DNMT1-interacting RNAs (DiRs): DIY Methylation for the Locus that has EverythingOctober 18, 2013The holidays are just around the corner, but the gifts are arriving early as a talented crew of epigenetics enthusiasts published some great work in Nature last week that suggests some RNA transcripts have more self control than a Jedi. Look out Luke, these under appreciated RNAs fit DNMT1 like a glove, and block local DNA methylation. […]
We are the 98%: Intergenic Regions (Finally) Get Some BuzzOctober 11, 2013Many chose to focus on the ‘wealthy’ two percent of our genome that produces protein, but we’ve always found the other 98% to be much more interesting. Thankfully, we’re past the days of referring to non-coding, intergenic regions as ‘Junk DNA’, and new research is proving how scientifically rich they really are. Dr. Emily Hodges […]
A Crash Course in Folate, Nutrition, and DNA Methylation Regulation with Dr. Patrick StoverOctober 10, 2013Dr. Patrick Stover, PhD, the Director of the Division of Nutritional Sciences at Cornell University, provides a great overview of the key role of folate in one-carbon metabolism, and DNA methylation in nutrition. Folate, Nutrition, and DNA Methylation Regulation There’s a long history in the whole field of folate metabolism, one-carbon metabolism, that outcomes […]
R-Loops and GC-skew Predicts Epigenetic Effects of CpG IslandsOctober 9, 2013With the EpiGenie Fortune Telling Machine in the shop most of the time, it’s pretty difficult for us to predict much of anything. (Yeah, we didn’t see the whole ‘twerking’ phenomenon coming either!) But some enterprising researchers have developed a way to classify and predict the epigenetic and transcriptional activities of various promoter regions based […]
Inducible Models Breathe New Life into Epigenetic Inheritance StudiesOctober 8, 2013Food, toxins, and stress can all have enormous effects on the epigenome, but pinning down the true epigenetic mechanisms at work is the tricky part. While it’s been difficult to determine mechanisms of action in standard animal models, new ones have been developed using Tetracyline-induced systems, that make it much simpler to tease out how […]
