Comprehensive proteomic study of the antiproliferative activity of a polyphenol-enriched rosemary extract on colon cancer cells using nano-liquid chromatography-Orbitrap MS/MS

ABSTRACT: A proteomics strategy based on nano-liquid 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 objectives of this study were (i) to detect changes in amplitude and kinetics of proteins altered by the treatment over the time; and (ii) to identify proteomic differences between the cytostatic and cytotoxic effect of the natural extract tested in order to gain insights into the antiproliferative mechanisms induced by rosemary polyphenols.
