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 […]
Reactivating “Fossil” Enhancers from Embryonic Development in Adult TissuesApril 10, 2019The Jurassic Park movies got the whole world excited about resurrecting dinosaurs from fossilized DNA, but more recent findings that the half-life of DNA is only 521 years mean that dream is science fiction. So, while the finer details of dinosaur genomes may be lost in the fossil record, new work has dug up epigenomic […]
Histone Demethylases Have a “Sixth Sense” about Oxygen Levels!April 7, 2019Many people make dubious claims of being endowed with more than the five traditionally recognized senses; their “sixth sense” providing the extrasensory perception needed to converse with spirits and ghosts and predict the future, among other fanciful claims. While there is a lack of any evidence for extrasensory powers and paranormal activity, robust studies have […]
