Dynamic Modeling of DNA Methylation “Turnover” Reveals Tasty Epigenetic MorselsJune 11, 2020While the word “turnover” may send the culinary-minded to the kitchen and the business-savvy straight to the accounts books, epigeneticists studying the turnover of DNA methylation have been left between a rock and a hard place! Researchers are in this unappetizing predicament as while we can accurately paint a genome-wide picture of DNA methylation levels, […]
A Rewired Metabolism Links the Aging Epigenome to Vision LossMay 16, 2020They say hindsight is 20/20, but for those of us looking over at a lifetime of memories, things might seem a little blurrier through our aging eyes. That’s because, unlike the fine wines, delectable whiskies, and smelly cheeses that we love to catabolize, the human epigenome tends not to age very well and a wide […]
Cannabis and Tobacco Produce a Double Hit on the EpigenomeMay 12, 2020While the epigenetic impacts of cannabis have been seen in sperm and adolescents, the effects on adults have not been well studied in large-scale studies. It’s commonly believed that smoking cannabis is less damaging than smoking tobacco; however, this is not backed by an abundance of actual data. Smoking tobacco is associated with numerous DNA […]
PRC2 Complex Genetic Variants Leave a DNA Methylation Signature in Overgrowth SyndromeApril 13, 2020While epigenetic modifications can leave their signatures on our genome, our genome can also leave its signature on our epigenomes. Genetic variants in epigenetic regulatory genes often cause disorders characterized by abnormal growth and intellectual disability. The Polycomb repressive complex-2 (PRC2) complex is a core regulator of chromatin structure through methylation of H3K27. EZH2, EED, […]
Tet3 Acts Against Anxiety in Forebrain NeuronsMarch 27, 2020While there are a lot of reasons to anxious these days, thankfully our neurons are using epigenetics to respond and adapt to the barrage of new information in our environment. In fact, DNA cytosine hydroxymethylation (5hmC) might be necessary to keep cognition in check, and a new research suggests that one of the enzymes that […]
