Epigenetic Cross-Talk: Histone H3K36 Methyltransferases Shape Sex Differences in Germ Cell DNA MethylationOctober 7, 2020Why did the DNA methylation cross the road? To cross-talk to the histone methyltransferase on the other side! In the epigenetics, cross-talk is how different marks “talk” to each other during development and is still something of mystery. NSD1 and SETD2 encode enzymes that chemically modify H3K36me2 and H3K36me3 respectively. Germline mutations in these genes […]
Racing Against the Epigenetic Clock: PRDM8 and Premature AgingOctober 5, 2020Scientists are always working against the clock, and recently, a team led by Wolfgang Wagner (RWTH Aachen University, Germany) used their ever-evaporating time to explore a potential link between telomere shortening and epigenetic clock acceleration in premature-aging associated bone marrow failure syndromes and describe a new disease biomarker! Patients with premature aging and difficult-to-diagnose bone […]
The One With All The Brand New Methylation FactorsSeptember 22, 2020Could there BE anymore genes affecting DNA methylation? Actually, yes! We always hear about the main cast of the methylation show, the DNMTs and the TETs, but where are all the supporting actors that attract, repel or otherwise interact with these stars? A new show (study) from the studio (lab) of Bastiaan Heijmans (Leiden University […]
A TET1 Thermostat Cranks up the Heat in Beige AdipocytesSeptember 9, 2020Many of us eagerly reach for the thermostat to crank up the heat a little as summer turns to fall, and now, a team of red-hot researchers studying heat generation in adipose tissue have discovered that the ten-eleven translocation 1 (TET1) DNA demethylase forms part of an epigenetic thermostat that could provide a means to […]
TET2 Overtrims the Methylation Hedges at Enhancers in Parkinson’s Disease NeuronsAugust 25, 2020It takes real restraint to prevent a routine hedge trim from turning into a horticultural horror show; and like an overzealous landscaper, new research shows that TET2 may be mowing down the methylome in Parkinson’s Disease (PD) neurons. The cognitive and motor symptoms of PD are caused by the degeneration of dopamine-producing neurons in the […]
