Enhancer Hypomethylation in Alzheimer’s Disease Brain Paves the Way for Cell DeathJune 15, 2019When it comes to understanding the epigenetics of aging, Alzheimer’s Disease (AD) has enhanced our knowledge in countless ways. This neurodegenerative disease has taught us to embrace healthy aging, and some surprising players have emerged from the examination of DNA methylation. Studies have uncovered a role for enhancers in AD; however, investigations into the consequences of DNA methylation at these […]
Heterochromatin Finds an Alternative Way to Lengthen TelomeresJune 15, 2019We recently advised our readers to “think different” when it came to the epigenetic control of maintenance in alternative lengthening of telomeres (ALT) cells, and now, a team of “out-of-the-box” thinkers from the lab of Jérôme Déjardin (Université de Montpellier, France) have described an unconventional link between ALT and telomeric heterochromatin formation. Previous results have […]
SETing up SETD2 as a Key Player in Oocyte DevelopmentJune 5, 2019While we’ve been fascinated by how epigenetic alterations during development SET the stage for adult life, in order to fully understand this relationship, we also have to examine how the stage for the development is SET by our epigenome. The epigenome of the oocyte is reprogrammed during early embryonic development; however, some marks remain at […]
The Chicken or the Egg: Beefing Up Causal Relationships Between DNA Methylation and Gene Expression in Skeletal MuscleJune 4, 2019An age old question: Which came first: the chicken or the egg? Determining the cause and effect relationship isn’t easy, and the same is true for the relationship between DNA methylation (DNAme) and gene expression. Who is strong-arming who? And even more important (at least to the pragmatists among us), how do both of these […]
Moms Hedonistic Lifestyle Echoes Through the Ages Thanks to Sperm tRNA-derived Small RNAsMay 28, 2019Sometimes a novel, a poem, or a song can enjoy such an outpouring from adoring fans that its influence can echo across the ages; however, recent work led by the lab of Daria Peleg-Raibstein (ETH Zurich, Switzerland) has established that mom’s unhealthy lifestyle can also echo across the ages leading to an observed negative impact […]
