Mental disorders like depression will likely affect 1/6 of Americans at some point in their life. That probability might be higher if you’re a Cleveland sports fan, but seriously, with mental illnesses affecting hundreds of millions of people globally each year, we’re glad to see an increasing focus on the epigenetics of these disorders. In […]

Memories Saved By DNA Methylation
The connection between memory and epigenetics has been has been a hot topic over the last couple of years. A recent article in Nature Neuroscience adds a new wrinkle to the subject by showing that DNA methylation helps to save memories, in addition to creating them. Sort of like using the “Keep Until I Delete” […]
DNA Methylation Takes a Back Seat To Histone Mods in miRNA Regulation
DNA methylation has long been considered a key epigenetic driver in transcription, but lately histone modifications have been stealing some of the regulatory thunder. Histone mods like H3K4me3, H3K27me3 and H4 acetylation have shown researchers they’re not afraid to get conrolling when it comes to miRNA transcription either. Researchers from the Institute of Genetics and […]
Hydroxymethylcytosine Shakes Up the Epigenetics Community
5-hydroxymethylcytosine’s (5-hmC) discovery last year in mammalian DNA (Kriaucionis & Heintz, Science, 2009. and Tahiliani et al., Science, 2009), left the epigenetics community more shaken than a 007 martini. Although its broader role (if any) in epigenetics remains a mystery today, early evidence suggests a few putative mechanisms that could have big implications: Conversion of […]
Self Renewal: Yoga, Meditation and DNA Methyltransferases
Despite all the technology “progress” over the years that was supposed to save us heaps of time, we seem to be busier than ever. Real-time internet and PDAs make communication a 24-7 gig, so it’s no wonder that there’s a big movement in self-renewal. We would take some time here to give you small ways […]
