Abstract B018: Restoration of p16INK4A expression in circulating tumor cells in patients with advanced solid tumors treated with deoxycytidine analogs and associated dynamic EMT phenotypic changes
Abstract:Background. In vitro experiments from multiple laboratories have shown that the methylation-induced silencing of the p16INK4A gene, a tumor suppressor gene, can be reversed by DNA methyltransferase (DNMT1) inhibitor-based epigenetic modulation. However, it remains unclear whether DNMT1 inhibitors induce re-expression of p16INK4A in patients treated with demethylation promoting agents. Here we report p16INK4A expression status in human circulating tumor cells (CTCs) and its dynamic changes during DNMT1 inhibito… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
