RNA Pol II: The Hardest Working Polymerase in EpigeneticsAugust 13, 2009Stop us if you’ve heard this one before: new research shows RNA Pol II is a key player in an epigenetic mechanism. Lately, RNA Pol II seems to be in the headlines more than the Jonas Brothers, only with fewer screaming, teen fans. Recently we featured a paper suggesting that non-coding tiRNAs are formed through […]
True Biomarker: DNA Methylation Steps up in Non-Invasive Prenatal DxAugust 5, 2009With the raging success of Twilight and True Blood, the masses of entertainment junkies out there have joined a well-established movement in the scientific community to make the most out of blood. There are a ton of potentially useful biomarkers floating around in our veins and the non-invasive sampling process has made blood a crowd […]
Clamping Down on Affinity ReagentsAugust 4, 2009U of Chicago protein engineer Shohei Koide knows there’s biology beyond the genome. Adding a methyl group onto a histone here, or an acetyl group onto one there, can change the way genes are expressed. There’s gotta be a reliable way of finding those postranslational mods in the first place, though, right? That’s why he […]
DNA Repeats; More Than Just Broken RecordsJuly 30, 2009Roughly half of the human genome is made up of repetitive DNA sequences, and yet their repetitive nature has made their study as difficult to decipher as James Brown lyrics on a scratched record. Recent evidence shows chromatin regulation of DNA repeats playing a role in gene regulation, genome integrity and chromosome maintenance, so scientists […]
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 […]
