Pro-apoptotic activity of the phytochemical Indicaxanthin on colorectal carcinoma cells (Caco-2) and epigenetic CpG demethylation of the promoter and…

Phytochemicals play prominent roles in human diet and nutrition as protective redo-active substances in prevention of several disorders and chronic diseases in humans. Today, their function as potent modulators of the mammalian epigenome-regulated gene expression is rapidly emerging. In the present study antiproliferative effects of Indicaxanthin (Ind) from the fruits of Opuntia ficus-indica (1), and potential influence on DNA methylation has been investigated on Caco-2 cells, a human cell line of colorectal carcinoma. Ind caused a clear dose- and time-dependent decrease of the cell proliferation (IC(50) 50 M) associated to apoptosis as demonstrated by phosphatidylserine externalization an…
