While a “bird’s-eye view” of a topic can often provide colossal insight, the opposite perspective can sometimes be just as useful! Recently, two fascinating studies of transgenerational epigenetic inheritance have taken a “worm’s-eye view” of this research area to deepen our understanding of this complex mechanism in the model nematode worm C. elegans. C. elegans […]

Choosing Sides: Tsix RNA Decapping Initiates the X Chromosome Inactivation Cascade
When 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 […]
Exosomal microRNA Roots for Regrowth by Raising Hairs in Retired Follicles
Move 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 […]
Expand Your Epigenetic Editing Portfolio With Targeted RNA m6A Methyltransferases!
For the last few years, DNA has cornered the methylation market as the Apple of epigenome editing tools, but a newly developed CRISPR-Cas13 system has epigenetic investors buying stock in RNA editing! 6-methyladenosine (m6A) is the most abundant RNA modification, and even though we know it’s involved in chromatin accessibility, RNA splicing and repairing damaged […]
Exon Skipping via Intergenerational Epigenetic Silencing Rescues Duchenne Muscular Dystrophy
While missing a gym class can happen from time to time without leaving you feeling too guilty (!), you really shouldn’t “skip” a fascinating new study that now describes how a maternally-transmitted epigenetic “exon skipping” effect may act as the foundation for new therapeutic approaches for a devastating genetic muscle-weakening disease. A majority of Duchenne […]
