A pan-cancer analysis of CpG Island gene regulation reveals extensive plasticity within Polycomb target genes
Abstract
A subset of CpG Island promoter genes are regulated by Polycomb-Repressive Complex 2 (PRC2+-CGI), which become DNA hypermethylated and silenced in cancer. Here, the authors investigate the transcriptomic and epigenomic characteristics of PRC2-occupied CGI and free CGI across pan-cancer types.
