Hi-C Gets the Low Down On Chromatin InteractionsJune 6, 2012The Hi-C you might remember from childhood was a delicious fruit punch drink with a mix of flavors. But as a recent Methods article points out, there’s a new Hi-C method on the scene. It’s not a juice beverage, but it is a tasty combination of techniques to analyze chromatin interactions that epigenetics researchers will […]
Nanofluidic Sorting and Analyzing of Single Methylated DNA Molecules in Real TimeMay 14, 2012Getting kids to line up single-file can be a challenge, but lining up single molecules for analyses can be just as frustrating. Now, researchers at Cornell report that they’ve done just that—they can line up single DNA molecules in a tiny channel in a nanofluidic device, sort them according to methylation state, then recover them […]
oxBS-Seq Breaks Through 5hmC Sequencing BarrierApril 26, 20125-Hydroxymethylcytosine (5hmC) has always been a bear to sequence, mostly because it’s virtually indistinguishable from its close relative, 5-methylcytosine (5mC) using classic bisulfite sequencing techniques. Now a new sample preparation method has hit the scene that can discriminate between cytosine, 5mC and 5hmC at single base resolution, called oxidative bisulfite sequencing (oxBS-Seq) that essentially smashes […]
ChIP & Bisulfite-Seq Cut Through Chromatin, DNA Methylation ChatterApril 4, 2012There are two sides to every story. Maybe even more if you ask a lawyer. So it only makes sense that two epigenetic mechanisms like chromatin and DNA methylation would each have something to say about the genomic regions they regulate. Two new methods each combine ChIP and bisulfite sequencing in order to cut through […]
Schizophrenia’s DNA Methylation FingerprintsApril 4, 2012By now, we’re all used to hearing about epigenetics in cancer or stem cell research, but its role in mental illness is still a pretty new concept. Understanding how exactly DNA methylation factors into schizophrenia may be a ways off, but new research promises to soon be able diagnose the condition through just a blood […]
Epigenetics at the Intersection of Environment and SelectionFebruary 28, 2012One of the most fascinating things about epigenetics is the implication it has for inheritance and evolution. Theories and hypotheses are everywhere, of course, but until Sir Richard Branson launches a Virgin Time Travel business, actually measuring the changes from thousands of years of natural selection will remain a pretty tall order. Two recent papers […]
Getting your Fix: Optimizing Chromatin Fixation for ChIP AnalysisFebruary 23, 2012Various ChIP methods are filled with all sorts of secret tricks that don’t seem to make it into the textbooks. This is especially true of the chromatin fixation step, where loads of variables make it difficult to pin down the exact conditions you need. Instead of learning the hard way, through failed experiments or apprenticing […]
Epigenetics and TwinsFebruary 8, 2012Every summer outside Cleveland, Ohio identical twins congregate at the Twins Days Festival. Twins from all over join in on an assortment of activities over three days that resembles a massive Doublemint® gum commercial. It’s not just the twins that get stoked for the festival though. As was highlighted in a nice article in National […]
DNA Methylation: 2011 Editor’s FavoritesJanuary 11, 2012DNA methylation research had a little something for everyone in 2011. Not only was it linked to cancer, diet, post-traumatic stress, socio-economic status and heritability; but more was learned about 5-hydroxymethylcytosine as well. As if that wasn’t enough, two new cytosine variants, 5-formylcytosine and 5-carboxylcytsosine, joined the party this year too. We can’t wait to […]
Technology & Methods: 2011 Editor’s FavoritesJanuary 11, 2012Without advanced technology, epigenetic research would flounder. (You’d also probably be reading this on a stone tablet, which are really tricky to post on the web.) Check out our favorite improvements in technologies and methods from 2011 that are making sure epigenetic research is staying on the cutting edge. Single Cell Methylation Profiling The Restriction […]
