Multi-omic Analyses Highlight an Epigenetic Treatment Strategy for Early-stage Alzheimer’sOctober 19, 2020Given the unfortunate failure of many treatment strategies for late-stage Alzheimer’s disease, researchers recently sought to gain some fresh new perspective from multiple angles by mounting a three-pronged transcriptomic, proteomic, and epigenomic attack to decipher the mechanisms controlling disease progression. Excitingly, the team behind this study now highlight the possibility of an early-stage epigenetic therapy […]
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 […]
Activity Matters: Enhancing our Understanding of Brain MaturationSeptember 29, 2020While epigenetic studies have shown us that the past sculpts the future, the mechanisms have remained a cognitive conundrum, particularly when it comes the developing brain. Thankfully, a stimulating new study has come forth to show how early-life brain activity flips a switch that establishes cell-type specific enhancers for life. To prime our brains with this […]
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 […]
Choosing Sides: Tsix RNA Decapping Initiates the X Chromosome Inactivation CascadeSeptember 9, 2020When it comes to X inactivation there are a huge number of studies that eXist. Despite being one of the best-studied epigenetic phenomena, the molecular decision making process behind the initiation of X chromosome inactivation (XCI) had remained far from fully understood. The regulation of the long non-coding RNA Xist initiates XCI. Xist’s antisense partner […]
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 […]
Epitranscriptomic tRNA Study Finally Reveals the “Y” of Aggressive Colon TumorsAugust 25, 2020Away with you Holmes, begone Poirot, and bye-bye Nancy Drew, because a terrific team of epigenetic detectives has solved an epitranscriptomic cold case to reveal the “Y” of aggressive colon tumors by linking CpG island promoter DNA hypermethylation of a key epitranscriptomic modifier and a transfer RNA (tRNA) modification to tumorigenesis. Epitranscriptomics includes the modification […]
Exosomal microRNA Roots for Regrowth by Raising Hairs in Retired FolliclesAugust 15, 2020Move over, Rogaine; the pharmacies of the future will carry hair regrowth treatments that contain microRNAs from hair follicle exosomes! There are creams, supplements, lasers and even surgery, but people struggling with hair loss still don’t have a convenient and effective treatment to help them restore their luscious locks. New treatments could involve injecting dermal […]
Cell free DNA MeDIP-seq is a Molecular Methylation Magnet for Machine Learning Cancer DetectionAugust 7, 2020Finding the cell free DNA (cfDNA) that most cell-types release into blood plasma is always a challenging task, but certain cancers release so little that it takes looking for a needle in a haystack to the next level. Methods for sorting the “hay” have often come up short, but two new studies successfully developed a […]
