Transcriptional repression and DNA hypermethylation of a small set of ES cell marker genes in male germline stem cells

Abstract excerpt

BACKGROUND: We previously identified a set of genes called ECATs (ES cell-associated transcripts) that are expressed at high levels in mouse ES cells. Here, we examine the expression and DNA methylation of ECATs in somatic cells and germ cells. RESULTS: In all ECATs examined, the promoter region had low methylation levels in ES cells, but higher levels in somatic cells. In contrast, in spite of their lack of...
