| Study Title | Estrogen-mediated inhibition of purine metabolism and cell cycle arrest as a novel therapeutic approach in colorectal cancer cells |
| Study Summary | Purine metabolism is upregulated in various cancers including colorectal cancer (CRC). While previous research has elucidated the role of Estrogen (E2) in metabolism remodeling and ATP production, its effects on purine metabolism remained unexplored. This study investigates the impact of E2 signalling on purine metabolism in CRC cells. We demonstrate, for the first time, a protective effect of E2 on CRC cells by targeting the purine synthesis pathway through its receptor estrogen receptor α (ERα). A full metabolomic profiling, next generation sequencing (NGS) and integrated OMICS were conducted for HCT-116 cells treated with E2 with and without silencing ERα. Our results revealed an enrichment of the purine metabolic pathway, with 27 genes in the de novo purine synthesis pathway downregulated in E2-treated CRC cells. Besides, E2-induced DNA damage, cell cycle arrest, and apoptosis are ERα-dependent. Our findings suggest potential therapeutic avenues for CRC treatment through antimetabolites targeting purine synthesis, as E2 treatment reduces the expression of relevant metabolites. |
