    Expression of Intratumoral Forkhead Box Protein 3 in Posttransplant Lymphoproliferative Disorders: Clinical Features and Survival Outcomes2015Inngår i: Transplantation, ISSN 0041-1337, E-ISSN 1534-6080, Vol. 99, nr 5, s. 1036-1042Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background. The infiltration of regulatory T cells (Tregs) in lymphomas is associated with better prognosis for some types of lymphomas, but knowledge of their role in posttransplant lymphoproliferative disorders (PTLDs) is limited. We therefore investigated the association between the expression of the Treg marker forkhead box protein 3 (FoxP3) in biopsies of PTLDs and survival, PTLD subtype, and clinical characteristics.

    Methods. Seventy-four cases of PTLD after solid organ transplantation with sufficient material for further analysis were included from a population-based study of PTLDs in Sweden. The PTLD biopsies were reevaluated and stained with the 236A/E7 antibody to detect FoxP3 in lymphoma tissue. Detailed clinical data were collected retrospectively from medical records.

    Results. Based on a cutoff level of 29 FoxP3+ cells per mm2, most (80%) of the PTLDs were FoxP3-. Forty-seven of 74 PTLDs displayed no FoxP3+ cells at all. The frequency of FoxP3+ cells did not influence median overall survival. The FoxP3- PTLDs were more frequently of T-cell phenotype (P=0.04), located at the graft (P=0.03), occurred earlier after transplantation (P=0.04), were more likely to develop in lung recipients (P=0.04), and in patients that had received anti T-cell globulin as induction therapy (P=0.02). The FoxP3+ PTLDs were associated with hepatitis C seropositivity (P=0.03). In multivariate analysis, B-cell PTLD and hepatitis C infection were independent predictors of FoxP3 positivity.

    Conclusion. Our findings suggest that intratumoral FoxP3+ Tregs do not influence survival in patients with PTLD. FoxP3+ Tregs are rare in PTLD, possibly because of heavy immunosuppression.

    The human adrenal gland proteome defined by transcriptomics and antibody-based profiling2017Inngår i: Endocrinology, ISSN 0013-7227, E-ISSN 1945-7170, Vol. 158, nr 2, s. 239-251Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The adrenal gland is a composite endocrine organ with vital functions that include the synthesis and release of glucocorticoids and catecholamines. To define the molecular landscape that underlies the specific functions of the adrenal gland, we combined a genome-wide transcriptomics approach based on mRNA sequencing of human tissues with immunohistochemistry-based protein profiling on tissue microarrays. Approximately two-thirds of all putative protein coding genes were expressed in the adrenal gland and the analysis identified 253 genes with an elevated pattern of expression in the adrenal gland, with only 37 genes showing a markedly higher expression level (>5-fold) in the adrenal gland compared to 31 other normal human tissue types analyzed. The analyses allowed for an assessment of the relative expression levels for well-known proteins involved in adrenal gland function, but also identified previously poorly characterized proteins in the adrenal cortex, such as FERM domain containing 5 (FRMD5) and protein NOV homolog (NOV). In summary, we provide a global analysis of the adrenal gland transcriptome and proteome, with a comprehensive list of genes with elevated expression in the adrenal gland and spatial information with examples of protein expression patterns for corresponding proteins. These genes and proteins constitute important starting points for an improved understanding of the normal function and pathophysiology of the adrenal glands.

    A clonal expression biomarker associates with lung cancer mortality2019Inngår i: Nature Medicine, ISSN 1078-8956, E-ISSN 1546-170X, Vol. 25, nr 10, s. 1540-1548Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    An aim of molecular biomarkers is to stratify patients with cancer into disease subtypes predictive of outcome, improving diagnostic precision beyond clinical descriptors such as tumor stage(1). Transcriptomic intratumor heterogeneity (RNA-ITH) has been shown to confound existing expression-based biomarkers across multiple cancer types(2-6). Here, we analyze multi-region whole-exome and RNA sequencing data for 156 tumor regions from 48 patients enrolled in the TRACERx study to explore and control for RNA-ITH in non-small cell lung cancer. We find that chromosomal instability is a major driver of RNA-ITH, and existing prognostic gene expression signatures are vulnerable to tumor sampling bias. To address this, we identify genes expressed homogeneously within individual tumors that encode expression modules of cancer cell proliferation and are often driven by DNA copy-number gains selected early in tumor evolution. Clonal transcriptomic biomarkers overcome tumor sampling bias, associate with survival independent of clinicopathological risk factors, and may provide a general strategy to refine biomarker design across cancer types.

    Measurements of ECP in serum and the impact of plasma coagulation2000Inngår i: Allergy. European Journal of Allergy and Clinical Immunology, ISSN 0105-4538, E-ISSN 1398-9995, Vol. 55, nr 5, s. 442-448Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Serum measurement of ECP (eosinophil cationic protein) is used as an indication of eosinophil activation in diseases such as asthma. The levels are dependent on sample handling, since a certain amount of ECP is released during storage. The mechanisms that induce this in vitro release are not known, but are supposed to be related to the coagulation process. The aim of this study was to investigate this further. ECP was measured in EDTA plasma and serum at 22 and 37°C from healthy individuals and patients with asthma and allergy. The serum levels of ECP increased with temperature. Recalcification of citrated plasma in the presence of granulocytes with increasing concentrations of Ca2+ showed a dissociation between the levels of ECP and the occurrence of coagulation. Further experiments indicated that plasma coagulation is not of any importance for the degranulation of eosinophils, nor did the addition of platelets or mononuclear cells affect the ECP levels. Incubations of granulocytes with fresh or frozen plasma and Ca2+suggested the existence of a freezing labile factor in plasma, necessary for the degranulation of healthy eosinophils, but not for allergic/asthmatic eosinophils. Further experiments with pure eosinophils indicated the existence of factors in serum and plasma which facilitate ECP secretion of an active, temperature-dependent nature. We conclude that the raised ECP levels in serum, as compared to EDTA plasma, are unrelated to the coagulation process, but are due to the continuous secretion ex vivo of ECP from active eosinophils. This process is time and temperature dependent and may be facilitated by eosinophil-activating components in the extracellular environment.

    Stability of Proteins in Dried Blood Spot Biobanks.2017Inngår i: Molecular & Cellular Proteomics, ISSN 1535-9476, E-ISSN 1535-9484, Vol. 16, nr 7, s. 1286-1296Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    An important motivation for the construction of biobanks is to discover biomarkers that identify diseases at early, potentially curable stages. This will require biobanks from large numbers of individuals, preferably sampled repeatedly, where the samples are collected and stored under conditions that preserve potential biomarkers. Dried blood samples are attractive for biobanking because of the ease and low cost of collection and storage. Here we have investigated their suitability for protein measurements. 92 proteins with relevance for oncology were analyzed using multiplex proximity extension assays (PEA) in dried blood spots collected on paper and stored for up to 30 years at either +4&deg;C or -24&deg;C.</p> <p>Our main findings were that 1) the act of drying only slightly influenced detection of blood proteins (average correlation of 0.970), and in a reproducible manner (correlation of 0.999), 2) detection of some proteins was not significantly affected by storage over the full range of three decades (34% and 76% of the analyzed proteins at +4&deg;C and -24&deg;C, respectively), while levels of others decreased slowly during storage with half-lives in the range of 10 to 50 years, and 3) detectability of proteins was less affected in dried samples stored at -24&deg;C compared to at +4&deg;C, as the median protein abundance had decreased to 80% and 93% of starting levels after 10 years of storage at +4&deg;C or -24&deg;C, respectively. The results of our study are encouraging as they suggest an inexpensive means to collect large numbers of blood samples, even by the donors themselves, and to transport, and store biobanked samples as spots of whole blood dried on paper. Combined with emerging means to measure hundreds or thousands of protein, such biobanks could prove of great medical value by greatly enhancing discovery as well as routine analysis of blood biomarkers.

    Method verification for homocysteine and a sustainability study on glucose, homocysteine and lactate in different sampling tubes2016Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    The pre-analytical phase is known for being the most important step in the laboratory process to reach reliable test results. If handling, transport or preparation of the sample is performed incorrectly the results can deviate from the true value. Today, sampling tubes contains various additives to stabilize concentration levels. The aim of this study was to test a new sampling tube containing fluoride/citrate for glucose, lactate and homocysteine. It was also of interest to evaluate the stability of those three analytes in lithium-heparin, sodium-fluoride/potassium oxalate and fluoride/citrate tubes. To perform the sustainability study, a method verification was done for homocysteine in plasma. The study was performed in a hospital laboratory on the routine instrument Roche Cobas 6000 analyzer. Blood was drawn from 20 patients and was analyzed at the hospital laboratory in Gävle. The blood samples were transported frozen to the laboratory in Hudiksvall and were used in the method verification. For the sustainability study, blood was drawn from 10 healthy volunteers in lithium-heparin, sodium-fluoride/potassium oxalate and fluoride/citrate tubes. The method verification was approved. The results showed that glucose was stable for up to 72 hours in Vacuette Glycaemia tube with fluoride/citrate and this tube also gave more accurate results. Lactate and homocysteine were also stable in fluoride/citrate, but needs further studies. All three analytes were more stable if the sample tubes were centrifuged as soon as possible after blood collection. Fluoride/citrate tubes were stable without centrifugation directly.

    A nonsense mutation in CEP55 defines a new locus for a Meckel-like syndrome, an autosomal recessive lethal fetal ciliopathy.2017Inngår i: Clinical Genetics, ISSN 0009-9163, E-ISSN 1399-0004, Vol. 92, nr 5, s. 510-516Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Mutations in genes involved in the cilium-centrosome complex are called ciliopathies. Meckel-Gruber syndrome (MKS) is a ciliopathic lethal autosomal recessive syndrome characterized by genetically and clinically heterogeneous manifestations, including renal cystic dysplasia, occipital encephalocele and polydactyly. Several genes have previously been associated with MKS and MKS-like phenotypes, but there are still genes remaining to be discovered. We have used whole exome sequencing (WES) to uncover the genetics of a suspected autosomal recessive Meckel syndrome phenotype in a family with two affected fetuses. RNA studies and histopathological analysis was performed for further delineation. WES lead to identification of a homozygous nonsense mutation c.256C>T (p.Arg86*) in CEP55 (centrosomal protein of 55 kDa) in the affected fetus. The variant has previously been identified in carriers in low frequencies, and segregated in the family. CEP55 is an important centrosomal protein required for the mid-body formation at cytokinesis. Our results expand the list of centrosomal proteins implicated in human ciliopathies and provide evidence for an essential role of CEP55 during embryogenesis and development of disease.

    Biomarker discovery in non-small cell lung cancer: integrating gene expression profiling, meta-analysis and tissue microarray validation2013Inngår i: Clinical Cancer Research, ISSN 1078-0432, E-ISSN 1557-3265, Vol. 19, nr 1, s. 194-204Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background:

    Global gene expression profiling has been widely used in lung cancer research to identify clinically relevant molecular subtypes as well as to predict prognosis and therapy response. So far, the value of these multi-gene signatures in clinical practice is unclear and the biological importance of individual genes is difficult to assess as the published signatures virtually do not overlap

    Methods:

    Here we describe a novel single institute cohort, including 196 non-small lung cancers (NSCLC) with clinical information and long-term follow-up. Gene expression array data was used as a training set to screen for single genes with prognostic impact. The top 450 probe sets identified using a univariate Cox regression model (significance level p<0.01) were tested in a meta-analysis including five publicly available independent lung cancer cohorts (n=860).

    RESULTS:

    The meta-analysis revealed 14 genes that were significantly associated with survival (p<0.001) with a false discovery rate <1%. The prognostic impact of one of these genes, the cell adhesion molecule 1 (CADM1), was confirmed by use of immunohistochemistry on tissue microarrays from two independent NSCLC cohorts, altogether including 617 NSCLC samples. Low CADM1 protein expression was significantly associated with shorter survival, with particular influence in the adenocarcinoma patient subgroup.

    CONCLUSIONS:

    Using a novel NSCLC cohort together with a meta-analysis validation approach, we have identified a set of single genes with independent prognostic impact. One of these genes, CADM1, was further established as an immunohistochemical marker with a potential application in clinical diagnostics.

    High-grade progression confers poor survival in pancreatic neuroendocrine tumors.2019Inngår i: Neuroendocrinology, ISSN 0028-3835, E-ISSN 1423-0194Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: Little is known about how Pancreatic Neuroendocrine Tumors (PanNETs) evolve over time and if changes towards a more aggressive biology correlates with prognosis. The purpose of this study was to characterize changes PanNET differentiation and proliferation over time, and to correlate findings to overall survival (OS).

    PATIENTS AND METHODS: In this retrospective cohort study we screened 475 PanNET patients treated at Uppsala University Hospital, Sweden. Sporadic patients with baseline and follow-up tumor samples were included. Pathology reports and available tissue sections were re-evaluated with regard to tumor histopathology and Ki-67 index.

    RESULTS: Forty-six patients with 106 tumor samples (56 available for pathology re-evaluation) were included. Median Ki-67 index at diagnosis was 7% (range 1-38%), grade 1 n=8, grade 2 n=36, and grade 3 n=2. The median change in Ki-67 index (absolute value; follow-up - baseline) was +14% (range -11 to +80%). Increase in tumor grade occurred in 28 patients (63.6%), the majority from grade 1/2 to grade 3 (n=24, 54.5%). The patients with a high-grade progression had a median OS of 50.2 months compared to 115.1 months in patients without such progression (HR 3.89, 95% CI 1.91-7.94, P<0.001).

    CONCLUSIONS: A longitudinal increase in Ki-67 index and increase in tumor grade were observed in a majority of PanNETs included in this study. We propose that increase in Ki-67 index and high-grade progression should be investigated further as important biomarkers in PanNET.

    Reduced expression of TRIM21/Ro52 predicts poor prognosis in diffuse large B-cell lymphoma patients with and without rheumatic disease2015Inngår i: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 278, nr 3, s. 323-332Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    ObjectiveTRIM21 (also known as Ro52) is an autoantigen in rheumatic disease and is predominantly expressed in leucocytes. Overexpression is associated with decreased proliferation, and the TRIM21 gene maps to a tumour suppressor locus. We therefore investigated the expression of TRIM21 in patients with diffuse large B-cell lymphoma (DLBCL) and its potential usefulness as a prognostic biomarker. Materials and methodsTRIM21 expression levels were assessed by immunohistochemistry in lymphoma biopsies from three cohorts of patients with DLBCL: 42 patients with rheumatic disease treated with a cyclophosphamide, vincristine, doxorubicin and prednisone (CHOP)-like regimen, 76 CHOP-treated and 196 rituximab-CHOP-treated nonrheumatic patients. Expression was correlated with clinical and biomedical parameters. TRIM21 expression was assessed in relation to lymphocyte proliferation by quantitative PCR and correlated with H-3-thymidine incorporation and propidium iodine staining. ResultsTRIM21 expression levels differed in the lymphomas compared to normal lymphoid tissue, with reduced expression correlating with shorter overall survival in all three cohorts. In the two larger cohorts, progression-free survival was assessed and was also found to correlate with TRIM21 expression. The association was independent of commonly used clinical prognostic scores, lymphoma subtype and several previously reported prognostic biomarkers. In agreement with this clinical observation, we noted an inverse correlation between TRIM21 expression and proliferation of leucocytes invitro. ConclusionsWe show that loss of TRIM21 expression is associated with more aggressive lymphoma and increased proliferation, whereas maintenance of TRIM21 expression is associated with better prognosis in patients with DLBCL. Based on our findings, we suggest that TRIM21 should be considered as a novel biomarker for lymphoma characterization and for predicting patient survival.

    A Biological Signature for Breast Ductal Carcinoma In Situ to Predict Radiotherapy Benefit and Assess Recurrence Risk2018Inngår i: Clinical Cancer Research, ISSN 1078-0432, E-ISSN 1557-3265, Vol. 24, nr 23, s. 5895-5901Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: Ductal carcinoma in situ (DCIS) patients and their physicians currently face challenging treatment decisions with limited information about the individual's subsequent breast cancer risk or treatment benefit. The DCI-SionRT biological signature developed in this study provides recurrence risk and predicts radiotherapy (RT) benefit for DCIS patients following breast-conserving surgery (BCS). Experimental Design: A biological signature that calculates an individualized Decision Score (DS) was developed and cross-validated in 526 DCIS patients treated with BCS = RT. The relationship was assessed between DS and 10-year risk of invasive breast cancer (IBC) or any ipsilateral breast event (IBE), including IBC or DCIS. RT benefit was evaluated by risk group and as a function of DS. Results: The DS was significantly associated with IBC and IBE risk, HR (per 5 units) of 4.2 and 3.1, respectively. For patients treated without RT, DS identified a Low Group with 10-year IBC risk of 4% (7% IBE) and an Elevated Risk Group with IBC risk of 15% (23% IBE). In analysis of DS and RT by group, the Elevated Risk Group received significant RT benefit, HR of 0.3 for IBC and IBE. In a clinicopathologically low-risk subset, DS reclassified 42% of patients into the Elevated Risk Group. In an interaction analysis of DS and RT, patients with elevated DS had significant RT benefit over baseline. Conclusions: The DS was prognostic for risk and predicted RT benefit for DCIS patients. DS identified a clinically meaningful low-risk group and a group with elevated 10-year risks that received substantial RT benefit over baseline.

    PD-L1 immunohistochemistry in clinical diagnostics of lung cancer: inter-pathologist variability is higher than assay variability2017Inngår i: Modern Pathology, ISSN 0893-3952, E-ISSN 1530-0285, Vol. 30, nr 10, s. 1411-1421Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Assessment of programmed cell death ligand 1 (PD-L1) immunohistochemical staining is used for decision on treatment with programmed cell death 1 and PD-L1 checkpoint inhibitors in lung adenocarcinomas and squamous cell carcinomas. This study aimed to compare the staining properties of tumor cells between the antibody clones 28-8, 22C3, SP142, and SP263 and investigate interrater variation between pathologists to see if these stainings can be safely evaluated in the clinical setting. Using consecutive sections from a tissue microarray with tumor tissue from 55 resected lung cancer cases, staining with five PD-L1 assays (28-8 from two different vendors, 22C3, SP142, and SP263) was performed. Seven pathologists individually evaluated the percentage of positive tumor cells, scoring each sample applying cutoff levels used in clinical studies: < 1% positive tumor cells (score 0), 1-4% (score 1), 5-9% (score 2), 10-24% (score 3), 25-49% (score 4), and > 50% positive tumor cells (score 5). Pairwise analysis of antibody clones showed weighted kappa values in the range of 0.45-0.91 with the highest values for comparisons with 22C3 and 28-8 and the lowest involving SP142. Excluding SP142 resulted in kappa 0.75-0.91. Weighted kappa for interobserver variation between pathologists was 0.71-0.96. Up to 20% of the cases were differently classified as positive or negative by any pathologist compared with consensus score using >= 1% positive tumor cells as cutoff. A significantly better agreement between pathologists was seen using >= 50% as cutoff (0-5% of cases). In conclusion, the concordance between the PD-L1 antibodies 22C3, 28-8 and SP263 is relatively good when evaluating lung cancers and suggests that any one of these assays may be sufficient as basis for decision on treatment with nivolumab, pembrolizumab, and durvalumab. The scoring of the pathologist presents an intrinsic source of error that should be considered especially at low PD-L1 scores.

    Vitamin D in relation to bone health and muscle function in young female soccer players2017Inngår i: European Journal of Sport Science, ISSN 1746-1391, E-ISSN 1536-7290, Vol. 17, nr 2, s. 249-256Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The present work investigated serum vitamin D (25(OH)D) status in relation to bone and muscle qualities and functions in 19 female soccer players (13-16 years) resident at northern latitude with very low sun exposure (∼32-36 h/month) during winter season (late January to early March). Serum 25(OH)D, parathyroid hormone and bone turnover markers osteocalcin (OC) and beta carboxy-terminal collagen cross-links (β-Ctx), as well as body composition and muscle performance were examined. Hormones were tested using routine laboratory methods. Fat mass, lean mass, and bone mineral density in whole body, as well as femur and lumbar spine were evaluated with dual-energy X-ray absorptiometry. Muscle performance was assessed through isokinetic knee extension and flexion, countermovement jump, and sprint running. 25(OH)D was low (50.5 ±   12.8 nmol l(-1)), whereas the values of bone turnover markers were markedly high (OC: 59.4 ±   18.6 µg l(-1); β-Ctx: 1075 ±   408 ng l(-1)). All bone and muscle measurements were normal or above normal. 25(OH)D was not significantly correlated with most of the parameters of bone and muscle quality or function, except the knee extension time to peak torque (r   =   -0.50, p =   .03). In conclusion, the level of vitamin D is markedly low in adolescent female soccer players during the winter in Sweden. However, vitamin D levels did not significantly correlate with measures of bone and muscle except a moderate correlation in time to peak torque in the knee extensors. The practical implication of low vitamin D levels in young growing female athletes remains unclear.

    CSF phosphorylated tau protein correlates with neocortical neurofibrillary pathology in Alzheimer's disease.2006Inngår i: Brain, ISSN 0006-8950, E-ISSN 1460-2156, Vol. 129, nr Pt 11, s. 3035-41Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Hyperphosphorylated tau protein (P-tau) in CSF is a core biomarker candidate of Alzheimer's disease. Hyperphosphorylation of tau is thought to lead to neurofibrillary changes, a neuropathological hallmark of this type of dementia. Currently, the question is unresolved whether CSF levels of P-tau reflect neurofibrillary changes within the brain of a patient with the illness. Twenty-six patients were included with intra-vitam CSF as well as post-mortem neuropathological data. In the CSF, P-tau phosphorylated at threonine 231 (P-tau231P) was analysed. Post-mortem, scores of neurofibrillary tangles (NFT) and neuritic plaques (NP) were assessed in frontal, temporal, parietal and hippocampal cortical areas. In the same cortical regions, load of hyperphosphorylated tau protein (HP-tau load) was determined. Concentrations of P-tau231P were measured in frontal cortex homogenates. We found significant correlations between CSF P-tau231P concentrations and scores of NFTs and HP-tau load in all neocortical regions studied. The score of NPs was correlated with CSF P-tau231P only within the frontal cortex. There was a correlation between P-tau231P in CSF and brain homogenates. These findings indicate that CSF P-tau231P may serve as an in vivo surrogate biomarker of neurofibrillary pathology in Alzheimer's disease.

    High Levels of Cerebrospinal Fluid Chemokines Point to the Presence of Neuroinflammation in Peripheral Neuropathic Pain: A Cross-Sectional Study of Two Cohorts of Patients Compared to Healthy ControlsManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Animal models suggest that chemokines are important mediators in the pathophysiology of neuropathic pain. Indeed, these substances have been called “gliotransmitters”, a term that illustrates the close interplay between glial cells and neurons in the context of neuroinflammation and pain. However, evidence in humans is scarce. The aim of the study was to determine a comprehensive cerebrospinal fluid (CSF) inflammatory profile for neuropathic pain patients. Our hypothesis was that we would thereby find indications of a postulated on-going process of central neuroinflammation.  

    CSF samples were collected from two cohorts of patients with neuropathic pain (n=11 and n=16, respectively) and healthy controls (n=11). The samples were analyzed with a multiplex proximity extension assay in which 92 inflammation-related proteins were measured simultaneously (Proseek® Multiplex Inflammation I, Olink Bioscience, Uppsala, Sweden). Univariate testing with control of false discovery rate, as well as orthogonal partial least squares – discriminant analysis, were used for statistical analyses.

    CSF levels of chemokines CXCL6, CXCL10, CCL8, CCL11, CCL23, as well as protein LAPTGF-beta-1, were significantly higher in both neuropathic pain cohorts compared to healthy controls, pointing to neuroinflammation in patients. These 6 proteins were also major results in a recent similar study in fibromyalgia patients. The findings need to be confirmed in larger cohorts, and the question of causality remains to be settled. Since it has been suggested that prevalent co-morbidities to chronic pain (e.g., depression, anxiety, poor sleep, and tiredness) also are associated with inflammation, it will be important to determine whether inflammation is a common mediator.

    LIPG-promoted lipid storage mediates adaptation to oxidative stress in breast cancer2019Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 145, nr 4, s. 901-915Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Endothelial lipase (LIPG) is a cell surface associated lipase that displays phospholipase A1 activity towards phosphatidylcholine present in high‐density lipoproteins (HDL). LIPG was recently reported to be expressed in breast cancer and to support proliferation, tumourigenicity and metastasis. Here we show that severe oxidative stress leading to AMPK activation triggers LIPG upregulation, resulting in intracellular lipid droplet accumulation in breast cancer cells, which supports survival. Neutralizing oxidative stress abrogated LIPG upregulation and the concomitant lipid storage. In human breast cancer, high LIPG expression was observed in a limited subset of tumours and was significantly associated with shorter metastasis‐free survival in node‐negative, untreated patients. Moreover, expression of PLIN2 and TXNRD1 in these tumours indicated a link to lipid storage and oxidative stress. Altogether, our findings reveal a previously unrecognized role for LIPG in enabling oxidative stress‐induced lipid droplet accumulation in tumour cells that protects against oxidative stress, and thus supports tumour progression.

    450K-array analysis of chronic lymphocytic leukemia cells reveals global DNA methylation to be relatively stable over time and similar in resting and proliferative compartments.2013Inngår i: Leukemia, ISSN 0887-6924, E-ISSN 1476-5551, Vol. 27, nr 1, s. 150-158Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In chronic lymphocytic leukemia (CLL), the microenvironment influences gene expression patterns; however, knowledge is limited regarding the extent to which methylation changes with time and exposure to specific microenvironments. Using high-resolution 450K arrays, we provide the most comprehensive DNA methylation study of CLL to date, analyzing paired diagnostic/follow-up samples from IGHV-mutated/untreated and IGHV-unmutated/treated patients (n=36) and patient-matched peripheral blood and lymph node samples (n=20). On an unprecedented scale, we revealed 2239 differentially methylated CpG sites between IGHV-mutated and unmutated patients, with the majority of sites positioned outside annotated CpG islands. Intriguingly, CLL prognostic genes (for example, CLLU1, LPL, ZAP70 and NOTCH1), epigenetic regulator (for example, HDAC9, HDAC4 and DNMT3B), B-cell signaling (for example, IBTK) and numerous TGF-β and NF-κB/TNF pathway genes were alternatively methylated between subgroups. Contrary, DNA methylation over time was deemed rather stable with few recurrent changes noted within subgroups. Although a larger number of non-recurrent changes were identified among IGHV-unmutated relative to mutated cases over time, these equated to a low global change. Similarly, few changes were identified between compartment cases. Altogether, we reveal CLL subgroups to display unique methylation profiles and unveil methylation as relatively stable over time and similar within different CLL compartments, implying aberrant methylation as an early leukemogenic event.

    Serotonin, ATRX, and DAXX Expression in Pituitary Adenomas: Markers in the Differential Diagnosis of Neuroendocrine Tumors of the Sellar Region.2017Inngår i: American Journal of Surgical Pathology, ISSN 0147-5185, E-ISSN 1532-0979, Vol. 41, nr 9, s. 1238-1246Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Differential diagnosis based on morphology and immunohistochemistry between a clinically nonfunctioning pituitary neuroendocrine tumor (NET)/pituitary adenoma and a primary or secondary NET of nonpituitary origin in the sellar region may be difficult. Serotonin, a frequently expressed marker in the NETs, has not been systematically evaluated in pituitary NETs. Although mutations in ATRX or DAXX have been reported in a significant proportion of pancreatic NETs, the mutational status of ATRX and DAXX and their possible pathogenetic role in pituitary NETs are unknown. Facing a difficult diagnostic case of an invasive serotonin and adrenocorticotroph hormone immunoreactive NET in the sellar region, we explored the immunohistochemical expression of serotonin, ATRX, and DAXX in a large series of pituitary endocrine tumors of different types from 246 patients and in 2 corticotroph carcinomas. None of the pituitary tumors expressed serotonin, suggesting that serotonin immunoreactive sellar tumors represent primary or secondary NETs of nonpituitary origin. Normal expression of ATRX and DAXX in pituitary tumors suggests that ATRX and DAXX do not play a role in the pathogenesis of pituitary endocrine tumors that remain localized to the sellar and perisellar region. A lack of ATRX or DAXX in a sellar NET suggests a nonpituitary NET, probably of pancreatic origin. One of the 2 examined corticotroph carcinomas, however, demonstrated negative ATRX immunolabeling due to an ATRX gene mutation. Further studies on a larger cohort of pituitary carcinomas are needed to clarify whether ATRX mutations may contribute to the metastatic potential in a subset of pituitary NETs.

    KIT protein expression and mutational status of KIT gene in pituitary adenomas2012Inngår i: Virchows Archiv, ISSN 0945-6317, E-ISSN 1432-2307, Vol. 460, nr 2, s. 171-181Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    KIT protein expression and mutational status of KIT gene in different types of tumours have been intensively studied since Imatinib Mesylate, KIT/PDGFRA tyrosine kinase inhibitor became available. However, only one immunohistochemical study on KIT expression in pituitary adenomas has been published. There are currently no reports on mutational status of KIT gene in pituitary adenomas. We have immunohistochemically investigated KIT expression in 252 pituitary adenomas and found cytoplasmic reactivity in 52.4% and membranous reactivity in 8.3% of all adenomas. There was statistically significant difference in KIT expression between clinically non-functioning, growth hormone- and adrenocorticotroph hormone-producing adenomas. The group with membranous expression was dominated by somatotropinomas and clinically non-functioning adenomas. KIT expression in a subset of adenomas was also confirmed by western blot analysis of 48 adenomas. Immunohistochemical KIT expression was correlated with basic clinical data and in a cohort of acromegalic patients with additional data (somatostatin receptor type 2A expression, response to somatostatin analogue treatment and mutational status of gsp oncogene). Exons 9, 11, 13 and 17 of KIT gene were searched for mutations in the tumours with membranous KIT expression and in a minority of tumours with cytoplasmic KIT expression using denaturing high-performance liquid chromatography and in suspected cases sequencing of one or more exons. No mutations in the examined exons were found. Our results may suggest a role of KIT in the pathogenesis of a subset of pituitary adenomas and point out the need for further research to find out if KIT-reactive adenomas could be sensitive to Imatinib Mesylate.

    Spindle cell oncocytoma of the adenohypophysis: report of a case with marked cellular atypia and recurrence despite adjuvant treatment.2009Inngår i: Clinical Neuropathology, ISSN 0722-5091, Vol. 28, nr 2, s. 91-95Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Spindle cell oncocytoma (SCO) of the adenohypophysis is a recently defined pituitary tumor mimicking a non-functioning macroadenoma and composed of mitochondrion rich tumor cells, positive for S-100, vimentin, epithelial membrane antigen and galectin-3 but lacking cytokeratins, pituitary hormones, and neuroendocrine markers. Derivation from pituitary folliculostellate cells (FSCs) has been suggested based upon immunohistochemical and ultrastructural characteristics shared by SCO and FSCs. 10 cases of SCO have been reported to date; of these, 8 underwent a benign clinical course and 2 recurred. We report a case of SCO with typical histologic and immunohistochemical features in addition to marked cellular pleomorphism and nuclear atypia. It showed slow regrowth over a 30-month period of follow-up despite combined surgical and radiotherapy. Despite the benign course of most reported cases, additional experience with longer follow-up are needed to assess clinical, histopathologic, and proliferative indices and their relevance to optimal therapy for this rare pituitary tumor.

    Incorporation of Pharmacogenomics into Routine Clinical Practice: the Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline Development Process2014Inngår i: Current drug metabolism, ISSN 1389-2002, E-ISSN 1875-5453, Current drug metabolism, Vol. 15, nr 2, s. 209-217Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Clinical Pharmacogenetics Implementation Consortium (CPIC) publishes genotype-based drug guidelines to help clinicians understand how available genetic test results could be used to optimize drug therapy. CPIC has focused initially on well-known examples of pharmacogenomic associations that have been implemented in selected clinical settings, publishing nine to date. Each CPIC guideline adheres to a standardized format and includes a standard system for grading levels of evidence linking genotypes to phenotypes and assigning a level of strength to each prescribing recommendation. CPIC guidelines contain the necessary information to help clinicians translate patient-specific diplotypes for each gene into clinical phenotypes or drug dosing groups. This paper reviews the development process of the CPIC guidelines and compares this process to the Institute of Medicine's Standards for Developing Trustworthy Clinical Practice Guidelines.

    Pharmacological targeting of peptidylarginine deiminase 4 prevents cancer-associated kidney injury in mice.2017Inngår i: Oncoimmunology, ISSN 2162-4011, E-ISSN 2162-402X, Vol. 6, nr 8, artikkel-id e1320009Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Renal insufficiency is a frequent cancer-associated problem affecting more than half of all cancer patients at the time of diagnosis. To minimize nephrotoxic effects the dosage of anticancer drugs are reduced in these patients, leading to sub-optimal treatment efficacy. Despite the severity of this cancer-associated pathology, the molecular mechanisms, as well as therapeutic options, are still largely lacking. We here show that formation of intravascular tumor-induced neutrophil extracellular traps (NETs) is a cause of kidney injury in tumor-bearing mice. Analysis of clinical biomarkers for kidney function revealed impaired creatinine clearance and elevated total protein levels in urine from tumor-bearing mice. Electron microscopy analysis of the kidneys from mice with cancer showed reversible pathological signs such as mesangial hypercellularity, while permanent damage such as fibrosis or necrosis was not observed. Removal of NETs by treatment with DNase I, or pharmacological inhibition of the enzyme peptidylarginine deiminase 4 (PAD4), was sufficient to restore renal function in mice with cancer. Tumor-induced systemic inflammation and impaired perfusion of peripheral vessels could be reverted by the PAD4 inhibitor. In conclusion, the current study identifies NETosis as a previously unknown cause of cancer-associated renal dysfunction and describes a novel promising approach to prevent renal failure in individuals with cancer.

    Neurophysiological characteristics of MuSK antibody positive Myasthenia Gravis mice: Focal denervation and hypersensitivity to acetylcholinesterase inhibitors2012Inngår i: Journal of the Neurological Sciences, ISSN 0022-510X, E-ISSN 1878-5883, Vol. 316, nr 1-2, s. 150-157Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Myasthenia Gravis (MG) patients with antibodies against the muscle specific tyrosine kinase (MuSK+) typically present with focal fatigue and atrophy of the facial and bulbar muscles, along with unbeneficial reactions upon administration of acetylcholinesterase inhibitors (AChEIs). This study addresses the neurophysiological characteristics in facial versus limb muscles, before and after intraperitoneal injection of AChEIs, in mice immunized with MuSK. We performed in-vivo neurophysiological examinations in the masseter and gastrocnemius muscles of mice with MuSK+experimental autoimmune MG (EAMG) and in healthy control mice before and after administration of AChEIs. Abnormal spontaneous activity (fibrillations) was observed in the masseter muscle of MuSK+mice. Furthermore, 94% of MuSK-immunized mice displayed so called extra discharges (EDs) upon administration of a therapeutic AChEI dose, in contrast to 22% of the control mice, indicating neuromuscular hyperactivity. These findings support functional denervation in the masseter muscle and neuromuscular hypersensitivity already at a standard dose of AChEIs in MuSK+EAMG.

    Usefulness of assessing repeater F-waves in routine studies2012Inngår i: Muscle and Nerve, ISSN 0148-639X, E-ISSN 1097-4598, Vol. 45, nr 4, s. 477-485Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: Repeater F-waves are sometimes seen in routine studies.

    METHODS: We retrospectively reviewed the clinical significance of repeater F-waves in median, ulnar, and fibular nerve recordings in 50 healthy subjects and groups of 50 patients each with diabetic polyneuropathy, amyotrophic lateral sclerosis, carpal tunnel syndrome, ulnar mononeuropathy, and L5 root lesion. The number of identical F-waves and their repetitions in samples of 20 stimuli were estimated.

    RESULTS: Repeater F-waves occurred significantly more frequently in all nerves and patient groups than in healthy individuals. Their persistence was negatively correlated with that of non-repeater F-waves.

    CONCLUSIONS: Based on the presented material and recording condition it appears that repeater F-waves differentiate between health and disease but not between different types of pathology of motor neurons or their axons. Even in routinely recorded samples of 20 traces, the index of repeater all F-waves could be used as a sign of nerve pathology.

    Persistent glucose transporter expression on pancreatic beta cells from longstanding type 1 diabetic individuals2011Inngår i: Diabetes/Metabolism Research Reviews, ISSN 1520-7552, E-ISSN 1520-7560, Vol. 27, nr 8, s. 746-754Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Recent reports have established the notion that many patients with longstanding type 1 diabetes (T1D) possess a remnant population of insulin-producing beta cells. It remains questionable, however, whether these surviving cells can physiologically sense and respond to glucose stimuli.

    METHODS: Frozen pancreatic sections from non-diabetic donors (n=8), type 2 diabetic patients (n=4), islet autoantibody-positive non-diabetic patients (n=3), type 1 diabetic patients (n=10) and one case of gestational diabetes were obtained via the network for Pancreatic Organ Donors. All longstanding T1D samples were selected based on the detection of insulin-producing beta cells in the pancreas by immunohistochemistry. RNA was isolated from all sections followed by cDNA preparation and quantitative real-time polymerase chain reaction for insulin, glucose transporter 1 (GLUT1), GLUT2 and GLUT3. Finally, immunofluorescent staining was performed on consecutive sections for all four of these markers and a comparison was made between the expression of GLUT2 in humans versus NOD mice.

    RESULTS: In contrast to islets from the most widely used T1D model, the NOD mouse, human islets predominantly express GLUT1 and, to a much lesser extent, GLUT3 on their surface instead of GLUT2. Relative expression levels of these receptors do not significantly change in the context of the various (pre-)diabetic conditions studied. Moreover, in both species preservation of GLUT expression was observed even under conditions of substantial leucocyte infiltration or decades of T1D duration.

    CONCLUSIONS: These data suggest that despite being subjected to multiple years of physiological stress, the remaining beta-cell population in longstanding T1D patients retains a capacity to sense glucose via its GLUTs.

    Method verification for aldosterone and renin assay - a reliable screening test for primary aldosteronism2018Independent thesis Advanced level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    Primary aldosteronism (PA) is a common form of secondary hypertension with an international prevalence rates between 5 and 10 %. It is characterized by a high autonomous aldosterone production that causes cardiovascular damage, renin suppression, hypertension, sodium retention, potassium excretion and hypokalemia. The screening of PA is a simple test measuring aldosterone to renin ratio (ARR) with immunoassay method. This test is currently considered as the most reliable screening tool for PA.

        The main objective of the study was to evaluate an ELISA-method, for detection of aldosterone and renin in blood plasma, to be used for routine analysis in the laboratory. The second aim was to investigate the effect of refreezing samples, considering that cryoactivation of prorenin might occur.

        One hundred blood samples were analysed, in regard to aldosterone and renin, by using two commercial ELISA assays (DRG ELISA from DRG Diagnostics, Germany) on a Dynex DS2 instrument. In addition, the accuracy and precision of the methods were calculated. The effect of refreezing was investigated with a series of eight samples, which were analyzed twice on the same instrument.

        Both assays performed well. The resulting data showed good precision and accuracy. The correlation between the original and refreezed samples was good, r = 0.989 and r = 1.0 for aldosterone and renin respectively. Considering that the study only included eight samples, further investigation is recommended.

        Evaluation showed that both immunoassays are reliable in diagnostic use and the ELISA-method is suitable to implement in the laboratory for routine analysis.

    Ten years transmission of the new variant of Chlamydia trachomatis in Sweden: prevalence of infections and associated complications.2018Inngår i: Sexually Transmitted Infections, ISSN 1368-4973, E-ISSN 1472-3263, Vol. 94, nr 2, s. 100-104Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: (nvCT) was discovered in Sweden. It has a deletion in the plasmid resulting in failed detection by the single target systems from Abbott and Roche used at that time, whereas the third system used, from Becton Dickinson (BD), detects nvCT. The proportion of nvCT was initially up to 65% in counties using Abbott/Roche systems. This study analysed the proportion of nvCT from 2007 to 2015 in four selected counties and its impact on chlamydia-associated complications.

    METHODS: sequencing. Ectopic pregnancy and pelvic inflammatory disease records were extracted from the national registers.

    RESULTS: -positive samples were analysed. The nvCT proportion significantly decreased in the two counties using Roche systems, from 56% in 2007 to 6.5% in 2015 (p<0.001). In the two counties using BD systems, a decrease was also seen, from 19% in 2007 to 5.2% in 2015 (p<0.001). Fifteen nvCT cases from 2015 and 102 cases from 2006 to 2009 had identical MLST profiles. Counties using Roche/Abbott systems showed higher mean rates of ectopic pregnancy and pelvic inflammatory disease compared with counties using BD systems.

    CONCLUSIONS: The nvCT proportion has decreased in all counties and converged to a low prevalence irrespective of previous rates. Genotyping showed that nvCT is clonal and genetically stable. Failing detection only marginally affected complication rates.

    KIT signaling is dispensable for human mast cell progenitor development2017Inngår i: Blood, ISSN 0006-4971, E-ISSN 1528-0020, Vol. 130, nr 16, s. 1785-1794Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human hematopoietic progenitors are generally assumed to require stem cell factor (SCF) and KIT signaling during differentiation for the formation of mast cells. Imatinib treatment, which inhibits KIT signaling, depletes mast cells in vivo. Furthermore, the absence of SCF or imatinib treatment prevents progenitors from developing into mast cells in vitro. However, these observations do not mean that mast cell progenitors require SCF and KIT signaling throughout differentiation. Here, we demonstrate that circulating mast cell progenitors are present in patients undergoing imatinib treatment. In addition, we show that mast cell progenitors from peripheral blood survive, mature, and proliferate without SCF and KIT signaling in vitro. Contrary to the prevailing consensus, our results show that SCF and KIT signaling are dispensable for early mast cell development.

    Cell surface proteomics identifies glucose transporter type 1 and prion protein as candidate biomarkers for colorectal adenoma-to-carcinoma progression2012Inngår i: Gut, ISSN 0017-5749, E-ISSN 1468-3288, Vol. 61, nr 6, s. 855-864Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and objective

    Early detection of colon adenomas at high risk of progression and early-stage colorectal cancer (CRC) is an effective approach to reduce CRC death rates. Current screening methods lack specificity as they detect many adenomas that will never progress to CRC. The authors aimed to identify cell surface protein biomarkers with extracellular domains that could be targeted for molecular imaging and discriminate low-risk adenomas and normal colon from high-risk adenomas and CRC.

    Design

    Cell surface proteins of five CRC cell lines were biotinylated, isolated and analysed by in-depth proteomics using gel electrophoresis and nanoliquid chromatography coupled to tandem mass spectrometry. Differential expression in adenomas and CRCs was based on mRNA expression and verified by immunohistochemical staining of tissue microarrays.

    Results

    In total, 2609 proteins were identified in the cell surface fractions. Of these, 44 proteins were selected as promising cell surface candidate biomarkers for adenoma-to-carcinoma progression based on the following criteria: protein identification in at least four out of five cell lines, a predicted (trans)membrane location and increased mRNA expression in CRCs compared to adenomas. Increased protein expression in high-risk adenomas and CRCs compared to low-risk adenomas was confirmed by immunohistochemistry for glucose transporter type 1 (gene symbol SLC2A1; p<0.00001) and prion protein (gene symbol PRNP; p<0.005).

    Conclusion

    This study revealed glucose transporter type 1, prion protein and 42 other cell surface candidate biomarkers for adenoma-to-carcinoma progression that could potentially serve as targets for emerging molecular imaging modalities like optical imaging, (19)F-MRI and positron emission tomography.

    Muscle atrophy and preferential loss of myosin in prolonged critically ill patients2012Inngår i: Critical Care Medicine, ISSN 0090-3493, E-ISSN 1530-0293, Vol. 40, nr 1, s. 79-89Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE:

    Muscle weakness contributes to prolonged rehabilitation and adverse outcome of critically ill patients. Distinction between a neurogenic and/or myogenic underlying problem is difficult using routine diagnostic tools. Preferential loss of myosin has been suggested to point to a myogenic component. We evaluated markers of muscle atrophy and denervation, and the myosin/actin ratio in limb and abdominal wall skeletal muscle, of prolonged critically ill patients and matched controls in relation to insulin therapy and known risk factors for intensive care unit-acquired weakness.

    DESIGN:

    Secondary analysis of two large, prospective, single-center randomized clinical studies.

    SETTING:

    University hospital surgical and medical intensive care unit.

    PATIENTS:

    Critically ill patients and matched controls.

    INTERVENTIONS:

    Intensive care unit patients had been randomized to blood glucose control to 80-110 mg/dL with insulin infusion or conventional glucose management, where insulin was only administered when glucose levels rose above 215 mg/dL.

    MEASUREMENTS AND MAIN RESULTS:

    As compared with controls, rectus abdominis and vastus lateralis muscle of critically ill patients showed smaller myofiber size, decreased mRNA levels for myofibrillar proteins, increased proteolytic enzyme activities, and a lower myosin/actin ratio, virtually irrespective of insulin therapy. Increased forkhead box protein O1 action may have played a role. Most alterations were more severe in patients treated with corticosteroids. Duration of corticosteroid treatment, independent of duration of intensive care unit stay or other risk factors, was a dominant risk factor for a low myosin/actin ratio. The immature acetylcholine receptor subunit γ mRNA expression was elevated in vastus lateralis, independent of the myosin/actin ratio.

    CONCLUSIONS:

    Both limb and abdominal wall skeletal muscles of prolonged critically ill patients showed downregulation of protein synthesis at the gene expression level as well as increased proteolysis. This affected myosin to a greater extent than actin, resulting in a decreased myosin/actin ratio. Muscle atrophy was not ameliorated by intensive insulin therapy, but possibly aggravated by corticosteroids.

    The effect of the UGT1A1*28 allele on survival after irinotecan-based chemotherapy: a collaborative meta-analysis2014Inngår i: The Pharmacogenomics Journal, ISSN 1470-269X, E-ISSN 1473-1150, Vol. 14, nr 5, s. 424-431Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To date, studies of irinotecan pharmacogenetics have mostly focused on the effect of the UGT1A1*28 allele on irinotecan-related toxicity. However, the clinical utility of routine UGT1A1*28 genotyping to pre-emptively adjust irinotecan dosage is dependent upon whether UGT1A1*28 also affects patient survival following irinotecan therapy. Previous observational studies evaluating the influence of UGT1A1*28 on survival have shown contradictory results. A systematic review and meta-analysis of both published and unpublished data were performed to summarize the available evidence of the relationship between the UGT1A1*28 allele and patient survival related to irinotecan therapy. Overall and progression-free survival meta-analysis data were available for 1524 patients and 1494 patients, respectively. The difference in the survival between patients of different UGT1A1*28 genotypes (homozygous, heterozygous or wild-type) who had received irinotecan was not found to be statistically significant. There was also no evidence of irinotecan dose, regimen or line of therapy having an impact on this association.

    Real-world prevalence of programmed death ligand 1 expression in locally advanced or metastatic non small-cell lung cancer: The global, multicenter EXPRESS study2019Inngår i: Lung Cancer, ISSN 0169-5002, E-ISSN 1872-8332, Vol. 134, s. 174-179Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives

    Tumor programmed death ligand 1 (PD-L1) expression is associated with improved clinical benefit from immunotherapies targeting the PD-1 pathway. We conducted a global, multicenter, retrospective observational study to determine real-world prevalence of tumor PD-L1 expression in patients with NSCLC.

    Materials and methods

    Patients ≥18 years with histologically confirmed stage IIIB/IV NSCLC and a tumor tissue block (≤5 years old) obtained before treatment were identified in 45 centers across 18 countries. Tumor samples from eligible patients were selected consecutively, when possible. PD-L1 expression was evaluated at each center using the PD-L1 IHC 22C3 pharmDx kit (Agilent, Santa Clara, CA, USA).

    Results

    Of 2617 patients who met inclusion criteria, 2368 (90%) had PD-L1 data; 530 (22%) patients had PD-L1 TPS ≥ 50%, 1232 (52%) had PD-L1 TPS ≥ 1%, and 1136 (48%) had PD-L1 TPS < 1%. The most common reason for not having PD-L1 data (n = 249) was insufficient tumor cells (<100) on the slide (n = 170 [6%]). Percentages of patients with PD-L1 TPS ≥ 50% and TPS ≥ 1%, respectively were: 22%/52% in Europe; 22%/53% in Asia Pacific; 21%/47% in the Americas, and 24%/55% in other countries. Prevalence of EGFR mutations (19%) and ALK alterations (3%) was consistent with prior reports from metastatic NSCLC studies. Among 1064 patients negative for both EGFR mutation and ALK alteration, the percentage with PD-L1 TPS ≥ 50% and TPS ≥ 1%, respectively, were 27% and 53%.

    Conclusions

    This is the largest real-world study in advanced NSCLC to date evaluating PD-L1 tumor expression using the 22C3 pharmDx kit. Testing failure rate was low with local evaluation of PD-L1 TPS across a large number of centers. Prevalence of PD-L1 TPS ≥ 50% and TPS ≥ 1% among patients with stage IIIB/IV NSCLC was similar across geographic regions and broadly consistent with central testing results from clinical trial screening populations.

    Detection of autoantibodies against cancer-testis antigens in non-small cell lung cancer2018Inngår i: Lung Cancer, ISSN 0169-5002, E-ISSN 1872-8332, Vol. 125, s. 157-163Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cancer testis antigens (CTAs) are defined as proteins that are specifically expressed in testis or placenta and their expression is frequently activated in cancer. Due to their ability to induce an immune response, CTAs may serve as suitable targets for immunotherapy. The aim of this study was to evaluate if there is reactivity against CTAs in the plasma of non-small cell lung cancer (NSCLC) patients through the detection of circulating antibodies. 

    To comprehensively analyse auto-antibodies against CTAs the multiplexing capacities of suspension bead array technology was used. Bead arrays were created with 120 protein fragments, representing 112 CTAs. Reactivity profiles were measured in plasma samples from 133 NSCLC patients and 57 cases with benign lung diseases. Altogether reactivity against 69 antigens, representing 81 CTAs, was demonstrated in at least one of the analysed samples. Twenty-nine of the antigens (45 CTAs) demonstrated exclusive reactivity in NSCLC samples. Reactivity against CT47A genes, PAGE3, VCX, MAGEB1, LIN28B and C12orf54 were only found in NSCLC patients at a frequency of 1%-4%. The presence of autoantibodies towards these six antigens was confirmed in an independent group of 34 NSCLC patients.

    In conclusion, we identified autoantibodies against CTAs in the plasma of lung cancer patients. The reactivity pattern of autoantibodies was higher in cancer patients compared to the benign group, stable over time, but low in frequency of occurrence. The findings suggest that some CTAs are immunogenic and that these properties can be utilized as immune targets.

    Profiling cancer testis antigens in non-small-cell lung cancer2016Inngår i: JCI INSIGHT, ISSN 2379-3708, Vol. 1, nr 10, artikkel-id e86837Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cancer testis antigens (CTAs) are of clinical interest as biomarkers and present valuable targets for immunotherapy. To comprehensively characterize the CTA landscape of non-small-cell lung cancer (NSCLC), we compared RNAseq data from 199 NSCLC tissues to the normal transcriptome of 142 samples from 32 different normal organs. Of 232 CTAs currently annotated in the Caner Testis Database (CTdatabase), 96 were confirmed in NSCLC. To obtain an unbiased CTA profile of NSCLC, we applied stringent criteria on our RNAseq data set and defined 90 genes as CTAs, of which 55 genes were not annotated in the CTdatabase, thus representing potential new CTAs. Cluster analysis revealed that CTA expression is histology dependent and concurrent expression is common. IHC confirmed tissue-specific protein expression of selected new CTAs (TKTL1, TGIF2LX, VCX, and CXORF67). Furthermore, methylation was identified as a regulatory mechanism of CTA expression based on independent data from The Cancer Genome Atlas. The proposed prognostic impact of CTAs in lung cancer was not confirmed, neither in our RNAseq cohort nor in an independent meta-analysis of 1,117 NSCLC cases. In summary, we defined a set of 90 reliable CTAs, including information on protein expression, methylation, and survival association. The detailed RNAseq catalog can guide biomarker studies and efforts to identify targets for immunotherapeutic strategies.

    Multiplex plasma protein profiling identifies novel markers to discriminate patients with adenocarcinoma of the lung2019Inngår i: BMC Cancer, ISSN 1471-2407, E-ISSN 1471-2407, Vol. 19, artikkel-id 741Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background:The overall prognosis of non-small cell lung cancer (NSCLC) is poor, and currently only patients with localized disease are potentially curable. Therefore, preferably non-invasively determined biomarkers that detect NSCLC patients at early stages of the disease are of high clinical relevance. The aim of this study was to identify and validate novel protein markers in plasma using the highly sensitive DNA-assisted multiplex proximity extension assay (PEA) to discriminate NSCLC from other lung diseases. 

    Methods:Plasma samples were collected from a total of 343 patients who underwent surgical resection for different lung diseases, including 144 patients with lung adenocarcinoma (LAC),68 patients with non-malignant lung disease, 83 with lung metastasis of colorectal cancers and 48 patients with typical carcinoid. One microliter of plasma was analyzed using PEA, allowing detection and quantification of 92 established cancer related proteins. The concentrations of the plasma proteins were compared between disease groups.

    Results:The comparison between LAC and benign samples revealed significantly different plasma levels for four proteins; CXL17, CEACAM5, VEGFR2 and ERBB3 (adjusted p-value < 0.05). A multi-parameter classifier was developed to discriminate between samples from LAC patients and from patients with non-malignant lung conditions. With a bootstrap aggregated decision tree algorithm (TreeBagger) a sensitivity of 93% and specificity of 64% was achieved to detect LAC in this risk population. 

    Conclusion:By applying the highly sensitive PEA, reliable protein profiles could be determined in microliter amounts of plasma. We further identified proteins that demonstrated different plasma concentration in defined disease groups and developed a signature that holds potential to be included in a screening assay for early lung cancer detection.

    The role of SATB2 as a diagnostic marker for tumors of colorectal origin: Results of a pathology-based clinical prospective study2014Inngår i: American Journal of Clinical Pathology, ISSN 0002-9173, E-ISSN 1943-7722, Vol. 141, nr 5, s. 630-638Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: Immunohistochemistry is an important extension to clinical information and morphology, and prevails as an invaluable tool for establishing a correct cancer diagnosis in clinical diagnostic pathology. The applicability of immunohistochemistry is limited by the availability of validated cell- and cancer-type specific antibodies, rendering an unmet need to discover, test, and validate novel markers. The SATB2 protein is selectively expressed in glandular cells from the lower gastrointestinal tract and expression is retained in a large majority of primary and metastatic colorectal cancers.

    METHODS: We analyzed the expression of SATB2 in all clinical cases (n = 840), in which immunohistochemistry for detection of CK20 was deemed necessary for a final diagnosis.

    RESULTS: SATB2 showed a high sensitivity (93%) and specificity (77%) to determine a cancer of colorectal origin and in combination with CK7 and CK20, the specificity increased to 100%.

    CONCLUSIONS: We conclude that SATB2 provides a new and advantageous supplement for clinical differential diagnostics.

    Prostasomes as Diagnostic, Prognostic and Therapeutic Vesicles2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis explores prostasomes and their ability to be used as a new diagnostic tool for prostate cancer. Alongside diagnosis, this thesis also suggests prostasomes as a tool for prognosis and therapeutic treatment in patients with prostate cancer. By further characterizing prostasomes we can identify a biomarker and also a method of visualizing and interpreting the information provided in order to conduct a correct and fast diagnosis for prostate cancer.

    In Paper I, we show that the prostasomal bilayered membrane consists of lipid rafts, clusters that holds cholesterol, sphingolipids and gives receptors a rigid platform upon which to work. We compare the proteomic content of prostasome lipid rafts with the entire prostasome membrane in the search for a specific biomarker. 

    In Paper II, we show that purified lipid rafts from the prostasome membrane can re-vesiculate and create new bioengineered vesicles. These new vesicles can carry different agents inside them and we find that the method is also applicable to blood cells. This suggests a new method for cell-specific delivery of drugs and cancer therapy. 

    In Paper III, we further characterize the prostasome membrane, this time mapping purinergic receptors. This could be used in the development of prostate cancer treatment and to gain better understanding of how prostasomes interact with surrounding cells in their ambient environment.

    In Paper IV, we investigate the difference in thymidine kinase 1 (TK1) enzyme activity between prostasomes and malignant exosomes. TK1 is considered to be a biomarker of cell proliferation and could therefore be used as a biomarker for prostate cancer diagnosis and progression.

    In summary, this thesis contributes to the puzzle of how to better diagnose, prognose and treat prostate cancer. Although it is mainly pre-clinical research it opens up new possibilities for the diagnosis and treatment of prostate cancer.

    Abstract [en]

    Prostasomes are exosomes derived from prostate epithelial cells through exocytosis by multivesicular bodies. Prostasomes have a bilayered membrane and readily interact with sperm. The membrane lipid composition is unusual with a high contribution of sphingomyelin at the expense of phosphatidylcholine and saturated and monounsaturated fatty acids are dominant. Lipid rafts are liquid-ordered domains that are more tightly packed than the surrounding non-raft phase of the bilayer. Lipid rafts are proposed to be highly dynamic, submicroscopic assemblies that float freely within the liquid disordered membrane bilayer and some proteins preferentially partition into the ordered raft domains. We asked the question whether lipid rafts do exist in prostasomes and, if so, which proteins might be associated with them. Prostasomes of density range 1.13-1.19g/mL were subjected to density gradient ultracentrifugation in sucrose fabricated by phosphate buffered saline (PBS) containing 1% Triton X-100 with capacity for banding at 1.10g/mL, i.e. the classical density of lipid rafts. Prepared prostasomal lipid rafts (by gradient ultracentrifugation) were analyzed by mass spectrometry and electron microscopy. The clearly visible band on top of 1.10g/mL sucrose in the Triton X-100 containing gradient was subjected to LC-MS/MS and more than 370 lipid raft associated proteins were identified. Several of them were involved in intraluminal vesicle formation, e.g. tetraspanins, ESCRTs and Ras-related proteins. This is the first comprehensive LC-MS/MS profiling of proteins in lipid rafts derived from exosomes. Data are available via ProteomeXchange with identifier PXD002163.

    Abstract [en]

    Purpose: In future therapeutics new formulas are needed that assure lower doses, fewer side effects, targeted administration and protection of the drug from degradation. In a first step to fulfil the requirements defined above, we carried out an in vitro study by developing a new procedure to encapsulate drugs using native vesicles first from prostasomes and then from erythrocyte membranes known to be well tolerated. The new method for production of drug delivery vesicles utilized osmotic loading of detergent resistant membranes (DRMs).

    Materials and methods: DRMs of prostasomes and prepared human erythrocyte membranes were extracted and separated in a sucrose gradient at a density of 1.10 g/mL containing 1% Triton X-100. These DRMs were characterized by electron microscopy (transmission and scanning EM) and loaded with low and high molecular compounds. PC3 prostate cancer cells were treated with doxorubicin loaded DRMs in triplicate. DAPI (nuclear fluorescent stain) was included and fluorescence microscopic pictures were taken before the cells were trypsinized and counted after 48h.

    Results: The content of the well separated band was observed ultrastructurally as small spherical, double layered membrane vesicles, (DRM vesicles) which harbored hyperosmolar sucrose of the gradient. Encapsulated hyperosmolar sucrose induced a transient osmotic lysis of the DRM vesicles when suspended in isotonic buffer containing loading molecules allowing vesicular inclusion. After this proof of concept, the method was finally employed for doxorubicin loading of DRM vesicles from human erythrocytes. When incubating such vesicles with PC3 cells a complete arrest of growth was observed in sharp contrast to PC3 cells incubated with plain doxorubicin in similar conditions.

    Conclusion: The present results open up new possibilities for using DRM vesicles as drug delivery vesicles.

    Intragraft Cytomegalovirus Protein Expression Is Associated With Reduced Renal Allograft Survival2011Inngår i: Clinical Infectious Diseases, ISSN 1058-4838, E-ISSN 1537-6591, Vol. 53, nr 10, s. 969-976Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Cytomegalovirus (CMV) infection is a risk factor for acute and chronic rejection of transplanted organs and is thought to mediate rejection indirectly.

    Methods: In this retrospective observational cohort study, early- and end-stage biopsies from renal allografts lost because of chronic allograft dysfunction (n = 29) were examined for CMV antigens and DNA using immunohistochemistry, in situ hybridization, and real-time polymerase chain reaction.

    Results: CMV immediate-early and late proteins were present in 27 (93%) of 29 of the end-stage chronic allograft dysfunction biopsies and in 64% of the corresponding early biopsies but not in pretransplant biopsies from CMV-seronegative donors (n = 3). Graft survival time was reduced in patients with moderate or high CMV levels in the graft soon after transplantation compared with that in patients with no or low CMV levels in the graft. No significant difference was observed in serum creatinine obtained at the time of early biopsies.

    Conclusions: We provide evidence that intragraft CMV protein expression is associated with end-stage chronic renal allograft dysfunction, that intragraft CMV levels increase as graft function deteriorates, and that CMV protein expression in the grafts soon after transplant is associated with reduced graft survival. Thus, CMV may have a pathological role in chronic renal allograft dysfunction.

    Analytically Sensitive Protein Detection in Microtiter Plates by Proximity Ligation with Rolling Circle Amplification2017Inngår i: Clinical Chemistry, ISSN 0009-9147, E-ISSN 1530-8561, Vol. 63, nr 9, s. 1497-1505Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Detecting proteins at low concentrations in plasma is crucial for early diagnosis. Current techniques in clinical routine, such as sandwich ELISA, provide sensitive protein detection because of a dependence on target recognition by pairs of antibodies, but detection of still lower protein concentrations is often called for. Proximity ligation assay with rolling circle amplification (PLARCA) is a modified proximity ligation assay (PLA) for analytically specific and sensitive protein detection via binding of target proteins by 3 antibodies, and signal amplification via rolling circle amplification (RCA) in microtiter wells, easily adapted to instrumentation in use in hospitals.

    METHODS: Proteins captured by immobilized antibodies were detected using a pair of oligonucleotide-conjugated antibodies. Upon target recognition, these PLA probes guided oligonucleotide ligation, followed by amplification via RCA of circular DNA strands that formed in the reaction. The RCA products were detected by horseradish peroxidase-labeled oligonucleotides to generate colorimetric reaction products with readout in an absorbance microplate reader.

    RESULTS: We compared detection of interleukin (IL)-4, IL-6, IL-8, p53, and growth differentiation factor-15 by PLARCA and conventional sandwich ELISA or immuno RCA. PLARCA detected lower concentrations of proteins and exhibited a broader dynamic range compared ELISA and iRCA using the same antibodies. IL-4 and IL-6 were detected in clinical samples at femtomolar concentrations, considerably lower than for ELISA.

    CONCLUSIONS: PLARCA offers detection of lower protein levels and increased dynamic ranges compared to ELISA. The PLARCA procedure may be adapted to routine instrumentation available in hospitals and research laboratories.

    CD99 is a novel prognostic stromal marker in non-small cell lung cancer2012Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 131, nr 10, s. 2264-2273Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The complex interaction between cancer cells and the microenvironment plays an essential role in all stages of tumourigenesis. Despite the significance of this interplay, alterations in protein composition underlying tumour-stroma interactions are largely unknown. The aim of this study was to identify stromal proteins with clinical relevance in non-small cell lung cancer (NSCLC). A list encompassing 203 stromal candidate genes was compiled based on gene expression array data and available literature. The protein expression of these genes in human NSCLC was screened using the Human Protein Atlas. Twelve proteins were selected that showed a differential stromal staining pattern (BGN, CD99, DCN, EMILIN1, FBN1, PDGFRB, PDLIM5, POSTN, SPARC, TAGLN, TNC, VCAN). The corresponding antibodies were applied on tissue microarrays, including 190 NSCLC samples, and stromal staining was correlated with clinical parameters. Higher stromal expression of CD99 was associated with better prognosis in the univariate (p=0.037) and multivariate (p=0.039) analysis. The association was independent from the proportion of tumour stroma, the fraction of inflammatory cells, and clinical and pathological parameters like stage, performance status and tumour histology. The prognostic impact of stromal CD99 protein expression was confirmed in an independent cohort of 240 NSCLC patients (p=0.008). Furthermore, double-staining confocal fluorescence microscopy showed that CD99 was expressed in stromal lymphocytes as well as in cancer associated fibroblasts. Based on a comprehensive screening strategy the membrane protein CD99 was identified as a novel stromal factor with clinical relevance. The results support the concept that stromal properties have an important impact on tumour progression.

    Prognostic Impact of Tumor Cell Programmed Death Ligand 1 Expression and Immune Cell Infiltration in NSCLC2019Inngår i: Journal of Thoracic Oncology, ISSN 1556-0864, E-ISSN 1556-1380, Vol. 14, nr 4, s. 628-640, artikkel-id S1556-0864(19)30009-7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Infiltration of T and B/plasma cells has been linked to NSCLC prognosis, but this has not been thoroughly investigated in relation to the expression of programmed death ligand 1 (PD-L1). Here, we determine the association of lymphocytes and PD-L1 with overall survival (OS) in two retrospective cohorts of operated NSCLC patients who were not treated with checkpoint inhibitors targeting the programmed death 1/PD-L1 axis. Moreover, we evaluate how PD-L1 positivity and clinicopathologic factors affect the prognostic association of lymphocytes.

    Methods: Cluster of differentiation (CD) 3 (CD3)-, CD8-, CD4-, forkhead box P3 (FOXP3)-, CD20-, CD79A-, and immunoglobulin kappa constant (IGKC)-positive immune cells, and tumor PD-L1 positivity, were determined by immunohistochemistry on tissue microarrays (n = 705). Affymetrix data was analyzed for a patient subset, and supplemented with publicly available transcriptomics data (N = 1724). Associations with OS were assessed by Kaplan-Meier plots and uni- and multivariate Cox regression.

    Results: Higher levels of T and B plasma cells were associated with longer OS (p = 0.004 and p < 0.001, for CD8 and IGKC, respectively). Highly proliferative tumors with few lymphocytes had the worst outcome. No association of PD-L1 positivity with OS was observed in a nonstratified patient population; however, a significant association with shorter OS was observed in never-smokers (p = 0.009 and p = 0.002, 5% and 50% cutoff). Lymphocyte infiltration was not associated with OS in PD-L1–positive tumors (50% cutoff). The prognostic association of lymphocyte infiltration also depended on the patients’ smoking history and histologic subtype.

    Conclusions: Proliferation, PD-L1 status, smoking history, and histology should be considered if lymphocyte infiltration is to be used as a prognostic biomarker.

    Cardiac Troponins and Their Prognostic Importance in Patients with Suspected Acute Coronary Syndrome and Renal Dysfunction2017Inngår i: Clinical Chemistry, ISSN 0009-9147, E-ISSN 1530-8561, Vol. 63, nr 8, s. 1409-1417Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Cardiac troponin (cTn) is important for risk assessment in patients with suspected acute coronary syndrome (ACS). cTn concentrations may, however, be affected by renal dysfunction, and the clinical importance of this interrelation is not well established. We investigated the association between cTnT and cTnI (measured with conventional assays and a more sensitive assay) with the estimated glomerular filtration rate (eGFR) and also assessed the ability of cTn to predict the 1-year all-cause mortality. METHODS: This retrospective registry-based study used data from 309454 admissions to Swedish coronary care units. cTn associations with eGFR and mortality were assessed using different regression models and by calculating multivariable-adjusted c-statistics. RESULTS: cTnT concentrations exhibited stronger associations with eGFR than cTnI concentrations (conventional cTnT assay: beta = -0.113; more sensitive cTnT assay: beta = -0.186; pooled conventional cTnI assays: beta = -0.098). Overall, cTnT provided greater prognostic accuracy than cTnI. This was most evident in non-ACS patients with normal or mildly reduced eGFR when using the more sensitive assay. Despite higher mortality rates, no consistent increases in the c-statistics of cTn were seen with severely reduced eGFR irrespective of the presence of ACS or non-ACS. CONCLUSIONS: cTnT concentrations exhibited stronger associations with reduced eGFR than cTnI concentrations in patients admitted because of suspected ACS. cTnT, particularly when measured using the more sensitive assay, also tended to be a stronger prognosticator. However, the relative significance of the obtained results must be considered in the context of the severity of renal dysfunction and whether ACS is present.
