The anti-oncogenic influence of ellagic acid on colon cancer cells in leptin-enriched microenvironment

Abstract

Ellagic acid (EA) has been proposed as a promising candidate for therapeutic use in colon cancer. Investigation of the effectiveness of EA in a leptin-enriched model might have been given a little interest. Here in, we investigated the anti-tumor effect of EA in the presence of leptin to reflect on therapeutic use of EA in obesity-linked colon cancer. Proven effective in leptin-enriched microenvironment, EA inhibited cell proliferation of HCT-116 and CaCo-2 cell lines, modulated cell cycle, translocated Bax to the mitochondrial fraction of cells, activated caspase-8, and reduced PCNA expression. The current study findings cast a beam of light on the potential therapeutic use of EA in obesity-related colon carcinogenesis.
