tiRNAs Emerge from FANTOM4July 22, 2009As deep sequencing platforms displace Nintendo’s Wii as the most popular toy in the research community, labs are discovering new varieties of RNAs at a dizzying pace. The latest edition, transcription initiation RNAs (tiRNAs), were recently identified by scientists at the University of Queensland in Australia, and published in Nature Genetics last April, by mining […]
How You Are Conceived Makes a Difference in Your EpigeneticsJuly 22, 2009Ahem! What we mean is that being conceived in a dish versus the natural way can affect the methylation of your DNA. Previous studies suggested that the less romantic method of putting sperm and egg together in vitro (assisted reproduction technology; ART) resulted in a higher risk of birth defects and rare disorders that involve […]
CLIPped Mouse Testes Reveal Novel Class of Small RNAsJuly 16, 2009Fish with germ cell-specific bait, and you get a new class of RNA. U Penn researchers CLIPped (Cross-Linked and ImmunoPrecipitated) mouse testis extract with the anti-DNA/RNA-binding protein MSY2, and caught a whole bunch of novel ~30 nt RNAs. While about 7% of these were known piRNAs, most came from a distinct class of testicular RNAs […]
NIH Digs into the Diet Movement with New Epigenetics Research GrantsJuly 16, 2009Nowadays it seems like everybody’s on some kind of a diet. Until recently, even public funding for epigenetic research had been leaner than a movie star on the South Beach diet. But with last year’s funding of the Roadmap Initiative and yesterday’s release of grant applications for the study of diet and epigenetics, things are […]
On Your Marks: Antibodies That Should be in Every Epigenetics Researcher’s FridgeJuly 15, 2009Chromatin is a complicated scene. Staying on top of who’s who in residue and degree-specific histone modifications and chromatin modifying proteins is more than a full time job. So, if you’re looking to jump start your investigations and pull down some quick hitting data, you’ll want to consider picking up on some quality antibodies targeting […]
