Getting Amped on Bisulfite ConversionJanuary 21, 2010Some of the biggest issues associated with bisulfite conversion aren’t really related to the bisulfite conversion process itself, but rather the downstream assays interpret the base conversion. After all, if a C is converted to a U in a test tube and nothing can assay it effectively, was in really converted? OK, enough bisulfite philosophy. […]
DNMT1 the Key to Radiant Skin?January 20, 2010The key to younger looking skin isn’t in expensive nip/tuck work or clay masks, but as a recent Nature paper shows, it’s actually DNMT1 that plays a major role. Thanks to DNMT1, whenever you shed dry skin, it is continually replaced with a new layer. That’s right—the same DNA methyltransferase that plays a role in […]
Epstein-Barr Virus is Crafty with DNA Methylation in LatencyJanuary 20, 2010The 80s TV show MacGyver featured a main character who was always able to get himself out of dangerous situations with just his wits and clever use of whatever materials happened to be lying around. In much the same way, EBV has figured out how to harness a host B cell’s DNAm machinery to modulate […]
More DNAm Data, Less Sample: Reduced Representation is No BSJanuary 13, 2010When someone tells you that they can save you time, money and sample, the magic trifecta for most scientists, your first thought is probably: “Bull&@%!”…your second thought might be: “Where do I sign up?” A new Nature Methods article from researchers at Broad, MIT, Harvard, and the Max Planck Institute promises to do just that […]
Two ES Cell Types Find Some Common GroundJanuary 6, 2010Coming from different backgrounds doesn’t make it impossible to find common ground. Just look at nuclear transfer-derived ES (ntES) and in vitro fertilized embryo-derived ES (IVFES) cells. Sure, they’re from different sides of the ES cell tracks, but as researchers from Michigan State University found out, once they’ve differentiated it hardly seems to matter. NtES […]
Zygotes Reboot On Paternal Methylation PatternsJanuary 6, 2010Kids often rebel against their parents as they grow up, and as it turns out, so do zygotes. Feeling “too cool” for their paternal sperm’s methylation patterns, zygotes assert their individuality by “rebooting” the inherited 5mCs and starting from scratch. But up until now, it was their little secret how they pulled it off. Researchers […]
RIP-Chip Tears Into miRNP Complex AnalysisJanuary 6, 2010Solving the mysteries of miRNA:mRNA interactions has been a tough case to crack. Correlation studies, and miRNA target prediction algorithms point us in the right direction, but their indirect nature is a little like going to trial with only circumstantial evidence. Researchers from University of Kentucky published a new paper demonstrating how RIP-Chip techniques can […]
Developing Technologies for Improved In Vivo Epigenetic Imaging/AnalysisDecember 15, 2009The NIH is opening up its wallet again for epigenetic technology development. $3.5M will be allocated in 2010 for developing in vivo epigenetic imaging and analysis technologies. According to the grant description, the NIH has recognized that “… the technologies available to determine the epigenetic state of tissues in vivo are extremely limited. The specific […]
Targeted Bisulfite Sequencing with Padlock ProbesDecember 8, 2009A rising star in the epigenetics field, Dr. Kun Zhang joined the UCSD faculty in 2007 after a post-doc with George Church at Harvard. Engaging in a little friendly competition with his former mentor, Zhang published a technique for targeted bisulfite sequencing using padlock probes (Nat. Biotechnol. 2009, 27, 353) at the same time the […]
LNA miR-122 Inhibitors Put HCV in Lockdown in vivoDecember 3, 2009miR-122 is a talented regulator. Sure it can negatively regulate gene expression by binding 3’ UTRs of target mRNAs, but it’s also shown that it can bind 5’ UTRs in the HCV genome just as well, and act as a positive regulator, giving the virus a hand with replicating its genome. Facilitating viral replication? Well, […]
