Wild-Type Inheritance of DNA MethylationJune 12, 2014It seems like all news lately is focused on the terrors of the world and transgenerational epigenetic inheritance has been no exception, usually with a strong focus on how an exposure or trauma finds a way to haunt generations. But now now an optimistic team from UCLA have shown that a lot can be learned from examining […]
Mechanosensitive DNA Methylation Keeps the Flow GoingJune 12, 2014Going with the flow is a sound strategy unless, of course, something is disturbing that flow. Researchers from the Georgia Institute of Technology and Emory University have shown that when blood flow is disturbed (d-flow) there is a responsive stream of gene expression changes triggered by mechanosensitive DNA methylation. Lead author Jessilyn Dunn shares that “It was […]
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 […]
DNA Methylation and Diet: A Lot to Chew OnMay 7, 2014Just in time for Mother’s Day, a new published report finds that a mother’s diet at the conception of her child causes life-long epigenetic differences in the metastable epialleles of the child with “permanent phenotypic consequences”. While it may seem that the “you are what you eat” card has been played to death to explain […]
Ancient History as Told by DNA MethylationApril 23, 2014To some people ancient history is anything prior to Facebook, for others, it might mean pre-iPod, but this new study uses DNA methylation to look WAY back in time and analyze the beginnings of human evolution (And yes, that’s before the internet was invented). Using epigenomics to look back into pre-historic times has taught us […]
DNA Cubes May Take Genome Editing Outside the BoxApril 22, 2014Through the use of some creative chemistry researchers have devised DNA cubes that can deliver molecular packages with precision that would make FedEx jealous. A geometrically genius team from McGill University crafted a piece of DNA origami that will only release it’s molecular payload when triggered by a specific mRNA. Here’s how they did it: Cubes were […]
Kit Competition Reveals Hacks to Help Bisulfite ConversionApril 16, 2014At first pass it may seem like all bisulfite conversion kits are essentially the same – and for the most part, that’s true. But according to a recently published evaluation, the conversion is all in the details, and if those are overlooked it can have a big impact on the results. Fortunately, researchers from the […]
Mood Killer: DNA Methylation Linked to Depressive DisorderApril 10, 2014There aren’t a lot of laughs to be had when discussing the very real and increasing problem of depression, but some new research supported by the brain initiative on sets of twins may help to lighten the mood a bit. Studies have begun popping up showing that epigenetic marks can be used to show if someone has […]
