DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...

Researchers have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via ...

(A) DNA methylation is maintained by DNMT1 on hemimethylated DNA after replication, while DNMT3A/3B catalyse de novo methylation on unmethylated DNA. In mammals, this modification is primarily found ...

Within the realm of genetic regulation, chromatin modifications such as histone methylation and acetylation play pivotal roles in the transcriptional control of genes. Disruptions in these processes ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Conventional view and the novel view proposed in this study about the function of H3K9 methylation (H3K9me). The conventional view considered the regulation by H3K9me as an on-off switch, where H3K9me ...
