The concurrence of DNA methylation and demethylation is associated with transcription regulation

The mammalian DNA methylome is formed by two antagonizing processes, methylation by DNA methyltransferases (DNMT) and demethylation by ten-eleven translocation (TET) dioxygenases. Although the dynamics of either methylation or demethylation have been …

Cellular Heterogeneity-Adjusted cLonal Methylation (CHALM) improves prediction of gene expression

Promoter DNA methylation is a well-established mechanism of transcription repression, though its global correlation with gene expression is weak. This weak correlation can be attributed to the failure of current methylation quantification methods to …

Acetylation on histone H3 lysine 9 mediates a switch from transcription initiation to elongation

The transition from transcription initiation to elongation is a key regulatory step in gene expression, which requires RNA polymerase II (pol II) to escape promoter proximal pausing on chromatin. Although elongation factors promote pause release …

PEpiD: a prostate epigenetic database in mammals

Epigenetic mechanisms play key roles in initiation and progression of prostate cancer by changing gene expression. The Prostate Epigenetic Database (PEpiD: http://wukong.tongji.edu.cn/pepid) archives the three extensively characterized epigenetic …
