Methylation decrease of BECN1 gene induced by phytochemical Indicaxantin in Caco2 cells: an epigenetic hypothesis of autophagy

2014

Autophagy is a highly conserved catabolic process that degrades and recycles intracellular components through the lysosomes [1]. The role of this process in tumorigenesis and tumor progression is controversial: in the early stages, it can block tumor growth and conversely it can promote its progression in the later stages [2]. The tumor suppressor BECN1 gene, encodes the protein Beclin 1, a marker of autophagy down-regulated in several types of cancer, such as colorectal cancer [3]. There are a lot of both genetic and environmental risk factors for colorectal cancer, including diet: for this reason, in accordance with epidemiological studies, consumption of foods rich in phytochemicals is w…
