Are LncRNAs the Future of Non-Invasive Prostate Cancer Testing?October 9, 2014Prostate cancer is the leading cause of mortality in North-American men and as a result many are forced to the clinic for some rather invasive biopsies, but thanks to some cool epigenetics involving lncRNAs, those once dreaded trips to the doctor’s office may soon be replaced a much less invasive urine test. Ranjan Perera and crew […]
Inheritance of Histone Mod Caught at Cell divisionSeptember 29, 2014Transgenerational Epigenetic Inheritance is one of our favorite topics, it’s done a great job of showing old school Mendelian inheritance who’s boss by creating the molecular complexity of complex traits. With phenotypes and exposures aplenty, the one thing that has been missing is catching the inheritance of an acquired epigenetic mark in the act. And that’s just what a […]
CRISPR Paves the Way for Large Fragment Genome EditingAugust 1, 2014Traditional large genome editing techniques employ indirect cloning of large genomes into bacterial artificial chromosome (BAC) plasmid. This technique is rather difficult and protracted. Thus, bypassing the BAC plasmid stage in large genome editing would be a big win for the application. The CRISPR-cas9 system, first discovered in Streptococcus pyogenes, is an important tool for […]
5′ UTR miRNA TargetingJuly 21, 2014The nightly news lately makes it seem like the world has gone upside down, and now we’ve got some science to back it. Honglei Zhou and Isidore Rigoutsos from Thomas Jefferson University recently revealed that mammalian miRNA targeting doesn’t always limit itself to 3′ miRNA action. It now seems that in addition to the traditional 3’UTR […]
Fetal Undernourishment Creates Temporary Transgenerational EffectJuly 11, 2014Transgenerational epigenetic inheritance is one hot topic, and it has long been shrouded in skepticism, but a number of cases and mechanistic insights into transgenerational epigenetic inheritance have helped molecular biology move past the limits of genetic determinism. Now a team from the University of Cambridge show that fetal nourishment results in a transgenerational epigenetic effect, rather than true […]
An Introduction to Epigenetic Editing with Dr. Marianne RotsJune 23, 2014Dr. Marianne Rots, Professor of Molecular Epigenetics and Head of Epigenetic Editing Laboratory at University of Groningen, Netherlands provides an informative overview of the current state of epigenetic editing approaches. Intro to Epigenetic Editing Epigenetic editing exploits the two main characteristics of epigenetics. On the one hand, epigenetic marks are heritable. This means the epigenetic […]
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 […]
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 […]
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 […]
