Members of the PIWI League Play Important Positions in the BrainMay 3, 2019It takes a special kind of small RNA to try out for the PIWI team. PIWI-interacting RNAs (piRNA) are small, have and adenine at their 10th position, an uracil at their 5’ end, and 2’-O-methylation at their 3’ end. This unique physique helps piRNA work with PIWI proteins to defend the germline against an aggressive transposon offense, but […]
New Epigenetic Clock Offers an Evolutionary Conserved View of Aging Through Ribosomal DNA MethylationApril 27, 2019With updates and novel iterations to the “epigenetic clock” occurring at a pace faster than our smartwatches, it’s about time a new player emerged in the world of epigenetic clocks. Not only can these specialist timepieces keep track of our chronological age, but they can also tell us how environmental factors affect the pace of […]
Giving Identity to the Masses: Antisense lncRNA Transcription Facilitates DNA Demethylation to Determine Promoter ChoiceApril 21, 2019As modern technology develops, we grow increasingly connected with one another while also striving to maintain our individual identities. Although some may blame social media for our desire to be unique snowflakes just like everyone else, exciting new research demonstrates a molecular mechanism for individual neuronal identity in the brain that may just be the […]
The Relationship Between CTCF and DNA Methylation? It’s Complicated…April 16, 2019Everyone knows one of those couples who keeps getting together and breaking up, as if they’re trying to decide how much they like each other. Well the chromatin architectural protein CTCF and DNA methylation have one of those relationships, and it just got more complicated! For years, we’ve been trying to decipher whether DNA methylation always prevents […]
Sugar Sticks it to Histones and Causes Problems for Chromatin ArchitectureApril 15, 2019Many of us have been lectured by our dentist about eating those delicious, sticky candies. Now, as it turns out, those cavity-causing sugars not only stick to your teeth but can stick to your histones too! Through a non-enzymatic process known as glycation, a glucose group is covalently attached to specific amino acids, which can […]
