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 […]
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 […]
Expand Your Epigenetic Editing Portfolio With Targeted RNA m6A Methyltransferases!August 4, 2020For 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 DystrophyJuly 29, 2020While 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 […]
Transgenerational Epigenetic Inheritance in Worms is A “Tail” of Two NucleotidesJune 2, 2020While the sprawls of London and Paris take center stage in the novel “A Tale of Two Cities,” we now seek to narrate an alternative epigenetic “tail” that tells all about two nucleotides! In this hefty tome, uridine and guanosine play the starring roles in a story passed down through generations and generations of worms; […]
How the Journey Towards Sperm Maturation Can Leave Offspring Stressed Out!April 23, 2020Queues! Security! Lost passports! While many will be currently reminiscing about the fun and frolics enjoyed during old holidays to far-flung exotic destinations, we generally choose to forget the enduring stress of the outward journey. However, a fascinating new study now provides evidence that any stress endured by maturing sperm during their epic voyage is […]
Inactive X Chromosomes SPENd Time Tucked Under the Epigenetic CoversFebruary 25, 2020When it’s the dead of winter, and the world outside is frozen solid, there’s no better place to be than under a mountain of warm blankets, like an inactivated X chromosome under a cloud of Xist long-noncoding RNA. Although we’ve known for a while that Xist is necessary for X chromosome inactivation (XCI), the mechanisms […]
SAXS Imaging Gets to the (Brave)heart of the Matter: First Full-Length Structure of a Long Non-Coding RNAFebruary 18, 2020It’s Valentine’s season, which means love is in the air, and heart-shaped novelties are abundant. But new research from the labs of Trushar Patel (University of Lethbridge, Alberta, Canada) and Karissa Sanbonmatsu (Los Alamos National Laboratory, New Mexico, USA) has flipped the script: they are giving us the shape of Braveheart, a long non-coding RNA […]
A Novel lncRNA Plays Cat and MAOs with Aggressive BehaviorsFebruary 4, 2020It’s the classic dilemma — do you eat that delectable morsel of cheese now or save it for later? If you tend to lack self-control, you might be at higher risk of impulsive or aggressive behavioral disorders, which have been linked to genes in the monoamine oxidase (MAO) family. A new study from the lab […]
The Epigenomics of Non-Coding DNA Variants with Dr. Guillaume BourqueDecember 20, 2019Dr. Guillaume Bourque from McGill University discusses his lab’s bioinformatic research examining the epigenomics of non-coding DNA sequence variants at the 2019 joint CEEHRC/IHEC meeting.
