O-GlcNAc transferase is a key regulator of DNA methylation and transposon silencing
Disruption of the enzyme O-GlcNAc transferase in mouse embryonic stem cells unleashes the activity of TET enzymes, which cause genome-wide decreases in DNA methylation and increases in DNA hydroxymethylation. This leads to de-repression of transposable elements, as well as the activation of some nearby genes.
