CpG Island (R)EvolutionJune 2, 2011CpG islands and their methylation patterns are the epigeneticists bread and butter, and it’s been assumed by many that there are evolutionary reasons behind their existence. New data suggests that not all CpG islands were created equal, and much like Donald Trump’s hair, can’t entirely be explained by natural selection. High-powered researchers from the Weizmann […]
Posttraumatic Stress Risk Altered by DNA MethylationJune 1, 2011After nearly a decade of sending troops into harms way, the U.S. is now coping with the aftermath that those situations can create for our armed forces, like posttraumatic stress disorder (PTSD). So it’s nice to see progress made towards understanding that condition. While many people are exposed to traumatic events, only a fraction will develop […]
EpiGenie 5-hmC Round-upJune 1, 2011We’re not entirely sure what the enigmatic base variant 5-hydroxymethylcytosine (5-hmC) does or why it’s important yet, but we do know it’s become one of our favorite epigenetic topics. Whether you’re a 5-hmC newbie, or just need a quick refresher, you’ll want to check out our favorite articles we’ve featured on the subject. Hydroxymethylcytosine Shakes […]
Histone Tails Take the Lead In De Novo MethylationMay 29, 2011“Newborn” (or de novo) DNA sequences come into this world just like newborn human babies—naked. So, how do new sequences get their DNA methylation on? Researchers from the Chinese Academy of Sciences say they’ve figured out what happens after the histones settle in: H3 tails that lack methylation at K4 bind to and activate de […]
Methylome Analysis Today: No One is PerfectMay 18, 2011With everyone focused on their own daily grind, its easy to gloss over some of life’s more philosophical questions like: “Does a falling tree make a sound if no one is there to hear it?” “What is the sound of one hand clapping?” or even “Are my methylome studies really accurate?” In an Epigenomics review […]
