Epigenetics Book Reviews and Chapter SummariesJune 6, 2012Over the last year EpiGenie has reviewed a couple of the latest epigenetics textbooks for the site. As good citizens of the earth, we of course looked for ways to recycle the books (and the knowledge inside of them) once our writers were done with them. So, we sent our copies out to readers and […]
Covaris AFA: Shear Elegance for ChromatinJune 5, 2012Chromatin shearing is a key step in the ChIP workflow that can dramatically impact your experimental outcome, but so often the task of chromatin shearing is tackled with just brute force. Sub-optimal sonication or enzymatic approaches are like using a sledgehammer to chop fruits and vegetables. Fortunately, Covaris’ Focused-ultrasonicators use Adaptive Focused Acoustics (AFA) technology […]
Webinar: Defining Chromatin State by Characterization of Chromatin RegulatorsJune 4, 2012EMD Millipore sponsored this recent webinar last month, that you can now replay at your convenience. Check it out. Chromatin Regulators (CRs) control chromatin structure, yet the rules governing these processes remain obscure. This presentation details a systematic approach to infer the function of CRs by mapping genome-wide CR-binding, and presents a novel approach for […]
Nature AND Nurture Both Contribute to DNA MethylationJune 1, 2012A recent pub led by a talented research team might call for a ceasefire in the old “nature vs. nurture” argument. Researchers in The Netherlands and the U.S. say their new study on people conceived or born during the Dutch Famine of 1944-1945 piles on even more evidence that the prenatal environment and your genes […]
For Histone Variants It’s All in the NameMay 31, 2012Understanding the nomenclature for histone variants can sometimes be like deciphering an ancient language without a translation app. And as more variants are discovered without a naming convention to guide the process, the confusion just keeps growing. That’s why Steve Henikoff and the rest of the attendees of the EMBO Workshop on Histone Variants last […]
Allele-Specific Histone Modifications Frequent Disease LociMay 24, 2012Just as “identical” twins can sometimes have a few noticeable differences (one has a mole on her cheek, the other doesn’t), alleles that are copies of the same gene also can be different. Allele-specific methylation (ASM) might get all the attention, but now researchers in the U.K. say that allele-specific histone modification (ASHM) might be […]

New Epigenetic Analysis Methods to Watch in 2012May 24, 2012Based on what we’ve seen so far in journals, conferences and interviews, 2012 could be a banner year for epigenetic analysis methods. New twists on old tricks, and futuristic technology advances have converged to create some really exciting new approaches in the field. Here are just a few that you’ll want to keep track of […]
DNA Methylation Deserts: Hot Spots for Structural Genomic MutationsMay 23, 2012Deserts typically stir up images of desolate landscapes sprinkled with cacti, but according to a new report, ‘methylation deserts’, the 1% of the genome with the lowest occurrence of DNA methylation, are actually fertile ground for structural genomic mutations. A research group from the Baylor College of Medicine knew that the human genome contains many loci […]
Enhancers Set the Stage for Stem Cell Differentiation during EmbryogenesisMay 23, 2012It’s amazing to think that we all started out as one cell with DNA from our parents inside. Now, researchers in Spain and the Netherlands say that they have a better idea of how development happens—and enhancers are showing them the way by pointing out active genes. The researchers knew that active enhancers are marked […]
