Phenolic acids are secondary plant compounds widespread in nature, which have potentially anticarcinogenic properties. In this study, the effect of ferulic acid (FA), which is the most common hydroxycinnamic acid in grain, on the mechanisms of colon carcinogenesis and tumor progression was investigated in a human colon carcinoma cell culture model (HT29 clone 19A). Antiproliferative and proapoptotic effects of FA were analysed. By means of proteome analysis (2D-PAGE, 2D-DIGE, LC-ESI-MS/MS) the influence of FA on the protein expression was investigated. It could be shown, that FA caused cytotoxic effects and significantly induced apoptosis only at high concentrations (> 3 mM). Simultaneously, the changes at the proteome level after FA-treatment were relatively small. Only at non-physiological concentrations did FA influence the processes of growth in HT29 clone 19A cells.
