METHYLOMIC SIGNATURE AND MOLECULAR MODELLING TO BETTER UNDERSTAND AUTOPHAGY INDUCED BY PHYTOCHEMICAL IN CACO-2 CELLS

The binomial “autophagy-cancer” is intricate and methylomic studies can help to understand it by changing point of view from a gene level to an -omic one. Recently, autophagy-modulating properties of several phytochemicals have attracted attention in anticancer research. We evaluated whether Indicaxanthin (IND), the peculiar known beneficial phytochemical of prickly pear, seasonally available in the southern Italy, could induce autophagy in Caco2 cells, and whether it results from an epigenomic modification and/or a direct molecular interaction. IND increased autophagy in Caco-2 cells; the methylomic signature, obtained by Reduced Representation Bisulfite Sequencing (15 million of clusters)…
