Abstract [en]

BACKGROUND:

Apart from inactivation of the MEN1 gene, the molecular mechanisms involved in tumorigenesis of the endocrine organs and MEN1-associated non-endocrine lesions remain unknown.

MATERIALS AND METHODS:

In order to learn more about down-stream effects upon MEN1 gene inactivation BON1 cells were transfected with a MEN1 gene construct (BON/M1C), and both RT-differential display and oligonucleotide microarrays were performed.

RESULTS:

Three genes (SMARCC1, OVCA2 and SRp55) found to be differentially regulated on differential display were corroborated by northern blots on cell line RNA when comparing MEN1 transfected cells with control (empty vector transfection). When comparing two different passages of BON/M1C with two passages of vector control using oligonucleotide microarrays, 25 up-regulated genes and 64 down-regulated genes could be found using a cut-off of >or=1.6 times.

CONCLUSION:

These findings might contribute to the understanding of the molecular pathways involved in MEN1 tumorigenesis, and may also provide knowledge of genes involved in sporadic endocrine tumorigenesis.
