Engineering (Epi)Genomes with CRISPR-CasMarch 14, 2013To really figure out what genes really do, you gotta get in there and get your hands dirty. That usually means deleting or modifying genes, or other regulatory regions. In a recent “Research Highlight” article, researchers at Johns Hopkins reviewed the three main ways to do this, including the increasingly popular CRISPR/Cas system. To engineer […]
DNA Methylation in Cancer Goes the Distance via EnhancersMarch 14, 2013We like having all the important things close by—a stash of chocolate, a latte, and the remote control. But sometimes important things are far away. Take enhancers, for example. Enhancers are often pretty far from the genes whose transcription they are “enhancing.” And now, it turns out that DNA methylation at these enhancers can affect […]
EpiGenie Book Reviews: EpigeneticsMarch 11, 2013If you’ve spent any time browsing the EpiGenie site, then you already know that we find epigenetics pretty interesting. So, of course any book with the title of Epigenetics is going to grab our attention. Epigenetics edited by Jörg Tost, gathers information from several top scientists working in various facets of epigenetics to assemble a […]
Correcting Brain Tissue Heterogeneity with DNA MethylationFebruary 28, 2013A few weeks ago, we highlighted some great work that has been very useful in helping correct for heterogeneous cell populations in blood. Now, we’ve just got wind of a clever new bioinformatics tool to correct for heterogeneity in the brain. Researchers have studied DNA methylation in brain tissue to see if there’s an association between that modification and […]
The Ups and Downs of miRNA and MeCP2 in Fetal BrainsFebruary 26, 2013What goes up must come down. And in the developing human brain, when miR-483-5p levels go up, it makes MeCP2 levels go down, according to researchers in a recent report. Problems with MeCP2 cause Rett Syndrome and other neurological disorders. MeCP2 levels are low in fetal stages of development, but high after birth in the […]
