Abstract [en]

In this work, a proteomics strategy based on nanoliquid chromatography-tandem mass spectrometry (nano-LC-MS/MS) using an Orbitrap high-resolution mass spectrometer together with stable isotope dimethyl labeling (DML) is applied to quantitatively examine relative changes in the protein fraction of HT-29 human colon cancer cells treated with different concentrations of a polyphenol-enriched rosemary extract over the time. The major objective of this study was to gain insights into the antiproliferative mechanisms induced by rosemary polyphenols. Using this methodology, 1909 and 698 proteins were identified and quantified in cell extracts. The polyphenol-enriched rosemary extract treatment changed the expression of several proteins in a time- and concentration-dependent manner. Most of the altered proteins are implicated, in the activation of Nrf2 transcription factor and the unfolded protein response. In conclusion, rosemary polyphenols induced proteomic changes that were related to the attenuation of aggresome formation and activation of autophagy to alleviate cellular stress..
