Epigenetics articles from across Nature Portfolio

Age has an impact on circadian rhythm. Here, the authors report that LKRSDH-dependent H3R17me2 and H3K27me3 at insulin-like peptide sites contribute to age-related circadian rhythm change in Drosophila.

DNMT3A and DNMT3L form a complex to deposit DNA methylation in mammalian germ cells. Here, the authors report that loss-of-function of ADD domains of DNMT3A and/or DNMT3L has various impacts on DNA methylation landscapes in mouse oocytes and sperm.

Gene-editing at the DM1 mutant locus revealed a fundamental difference between undifferentiated and differentiated cell states: abnormal epigenetic modifications cannot be repaired after differentiation.

In this Tools of the Trade article, Dongsheng Bai and Chenxu Zhu describe SIMPLE-seq, a scalable single-cell sequencing method that simultaneously decodes the cytosine modifications 5mC and 5hmC.

We round up some recent stories from the Nature Briefing.

Carrying a baby creates some of the same epigenetic patterns on DNA seen in older people.

We show that in addition to promoter activation, MYC drives cancer progression by activating transcriptional enhancers via a distinct mechanism. MYC cooperates with several other proteins at these cis-regulatory regions to change the epigenome and promote recruitment of RNA polymerase II and enhancer transcription.
