5hmU: Tet’s Newest Base on the BlockJune 9, 2014While Apple seems focused on reducing complexity, the epigenome just can’t stop increasing it. Researchers from the Ludwig-Maximilians-University in Munich have shown that Tet enzymes oxidize not only the methyl group of methyl-cytosine (mC) but also thymine (T). An analog to the traditional oxidation of 5mC to 5hydroxymethyl-cytosine (5hmC), this case generates hydroxymethyl-uracil (5hmU). By tracing metabolically stable isotopes […]
CTCF Prevents Cancerous LandscapesMay 26, 2014This is the time of year to spruce up the garden, but a recent report has us thinking more about a DNA Methylation landscaper: CTCF. Epigenetic marks have long been associated with cancer and resarchers from the Fred Hutchinson Cancer Research Center (Seattle) have shown that when the epigenetic groundskeepers (i.e. CTCF) are short handed, the epigenetic […]
lncRNAs Give a Shout Out to Imprinted GenesMay 22, 2014For a while there, it didn’t seem like long non-coding RNAS (lncRNAs) had very much to say on the subject of genomic imprinting. But some new evidence shows that lncRNAs have found their voice, shouting loud and clear as a cross-talk conduit between imprinted regions. Researchers from Hebrew University (Jerusalem) introduced a new concept into […]
Genome Editing & iPSCs Reveal Matters of the HeartMay 15, 2014Matters of the heart are always complicated (Just ask Dr. Phil!), but this is especially true when appropriate cardiac models aren’t available to medical researchers. Fortunately, a reverse engineering team from Harvard has found a way to combine the CRISPR/Cas9 genome editing system and induced pluripotent stem cells (iPSC), to create a “heart-on-chip” technology that’s […]
Synthetic DNA Adds Storage Capacity to Genome EditingMay 9, 2014Just when you thought you’d mastered both your linguistic and scientific alphabets, it looks like it’s time to dust off the ol’ learning cap and re-learn your ATGCs because the two-base-pair genetic alphabet has just got some fancy new characters. A clever team from the Scripps Research Institute in La Jolla (California) have now expanded the inheritable […]
