Evasive Maneuvers! LINE-1 at the Helm Outwits Epigenetic RepressionJuly 16, 2019While the above title may conjure up images of Star Wars-esque galactic battles, the epic clash between the LINE-1 (L1) retrotransposon and repressive forces takes place on the scale of microns instead. This war has been waging in the human genome for thousands of years: L1 attempts to replicate and integrate into the genome, while […]
Shifting Sex: Social Stress Throws Epigenetics in Reverse for Female Bluehead WrassesJuly 15, 2019Have you ever run into an unexpected detour on your commute? Whether it be an ice patch, flood, or even a mudslide, mother nature can reroute even the best laid plans, but for some species, changes in the environment have much higher stakes than being late for work or that much needed vacation. In fact, […]
Mitochondrial Memes: How the Powerhouse of the Cell also Drives Epigenomic AlterationsJuly 12, 2019The appreciation of the mitochondrion as “the powerhouse of the cell” has become as culturally pervasive as some of our favorite memes; however, a powerful new study now shows that signals deriving from this double-membrane-bound ATP-generating organelle represent a major driving force behind alterations to the epigenome. A talented team of researchers from the lab […]
Epigenetic Heirlooms: The C. elegans Behavioral Legacy is Inherited Through Small RNAsJuly 2, 2019Some families have heirlooms that get passed down from generation to generation but if you’re a nematode, you might inherit more than just your Grandpa’s pocket watch! The phenomenon of transgenerational epigenetic inheritance (TEI) was first discovered in Caenorhabditis elegans, where environmental stressors can alter physiological responses in offspring up to 20 generations later! Since […]
Mutant DNMT3A Underperforms in Overgrowth SyndromeJune 25, 2019If you’re underperforming at work, you might end up with a rejected paper, failed experiments, or an angry boss. However, this isn’t so bad when compared to how mutated DNMT3A underperforms in its role as a DNA methyltransferase, since that can result in a pathogenic overgrowth known as Tatton-Brown-Rahman syndrome (TBRS). Despite DNMT3A’s known role […]
