Epigenetics in Evolution with Dr Eva JablonkaMarch 13, 2011Dr. Eva Jablonka discusses the role of epigenetics in evolutionary biology. This short take was shot during a break at Keystone Symposia’s meeting on Environmental Epigenomics and Disease Susceptibility held in March 2011 in Asheville, North Carolina. Epigenetics in Evolution Well, what I’m doing really is theoretical work, and I’m mainly interested in the evolutionary […]
5-Azacytidine: The Charlie Sheen of DNA Methylation Inhibitors?March 13, 2011As we’ve all recently witnessed, some actors have polished public images but are a mess in real life. After reading two recent papers by groups in Los Angeles and Turkey, it sounds like the same could be said of 5-azacytidine (Vidaza®). Mounds of clinical data now show that 5-azacytidine is a good treatment for blood […]
EpiGenie Interview: Dr. Randy Jirtle on Environment EpigenomicsMarch 10, 2011We caught up with Dr. Randy Jirtle to hear more about his transition from nuclear engineer to imprinting guru and chief publicist for Agouti mice. Dr. Jirtle is a co-organizer for the epigenetics star-studded Keystone Environmental Epigenomics and Disease Susceptibility Meeting that kicks off March 27th, 2011 in Asheville, North Carolina. In the interview he […]
Adiós Amnio: Noninvasive Down Syndrome Screening with Fetal DNA MethylationMarch 6, 2011Oscar winner Natalie Portman and other pregnant women may glow with hormones. But to-be-mamas lose some of that radiance at the thought of having a long needle dig into their bellies to check their unborn baby for Down syndrome. Now thanks to some intrepid researchers, pregnant women might be able to ditch the stressful prenatal […]
DNA Methylation Links Low Maternal Folate with Neural Tube DefectsMarch 1, 2011Increasing evidence supports that mom’s parental duties start way before birth. Make sure you do this…don’t do that, but don’t stress over it. It’s great to see researchers starting to get a hold of the “why” behind all the rules. Not getting enough folate from mom puts fetuses at risk for neural tube defects such […]
Stressed Out Moms MethylateMarch 1, 2011Raising babies is a stressful thing, made even more so when Mom herself is raised: a meter high on a Plexiglas platform, while she’s pregnant, that is. The effect on her kids – er, pups – is manifest in brain and body weight, in behavioral development, and even epigenetically. Researchers from the University of Lethbridge […]
Turning Back the Clock: Epigenetics, iPSCs and AgingFebruary 25, 2011Aging can be a real downer, but for some individuals premature aging is a lot more serious than a few aches and pains the morning after some touch football. Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal genetic disorder where the victims speed through aging. It is caused by a point mutation in the […]
5-mC Stabilizes High-Maintenance MethyltransferasesFebruary 16, 2011Many things in life–like diets, exercise routines, and blogs–are easier to start than maintain. The same can be said for DNA methylation. De novo methyltransferases establish DNA methylation patterns in embryonic stem cells, but exactly how somatic cells maintain these patterns is puzzling. Now researchers at the University of Southern California have identified a new […]
Genome-Wide Methylation Sequencing Hits the Fast LaneFebruary 11, 2011Genome-wide DNA methylation sequencing hasn’t been much more than sci-fi reading for most labs. Sure there’ve been some great papers with really slick technologies, but many researchers just don’t have access to them. In many cases, no single lab can handle the complete experimental workflow from sample prep to data management/analysis, requiring collaborations with other […]
MethylC-Seq Delivers First Single Base Resolution Methylation Profiles of iPSCsFebruary 2, 2011There’s always something a bit “off” when you look at aging starlets who’ve had some work done. In the same way, researchers in California and Wisconsin recently found that induced pluripotent stem cells (iPSCs) generated from old somatic cells aren’t quite the same as youthful embryonic stem cells (ESCs)—the epigenetics are “off”. Sure, iPSCs and […]
