DNA Methylation Tells Splicing Machinery Where to CutMarch 21, 2013In a recent paper, researchers say that DNA methylation, nucleosomes, and the “GC architecture” of an exon and its flanking introns may actually act as a big “cut here” sign stuck to the DNA or RNA to show where splicing is supposed to happen. Evidence that DNA methylation and nucleosomes are linked to splicing has […]
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 […]

lncRNA Regulates Tumor Suppressor Two WaysMarch 4, 2013A little redundancy can be a good thing. A team of researchers led by Dr. Kevin Morris at the Scripps Institute, in La Jolla, recently showed that a little redundancy in the regulation of PTEN, a tumor suppressor gene, can be pretty useful…but also really complicated. PTENpg1, a PTEN pseudogene, regulates PTEN via both sense […]
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 […]
EpiGenie Reviews: Genomic Imprinting – Methods and ProtocolsFebruary 24, 2013Genomic imprinting, or examining instances where paternal and maternal genomes aren’t represented equally, has kept many brilliant minds busy for decades. It has also established the foundations for emerging field of epigenetics. In the 2012 update of Genomic Imprinting: Methods and Protocols, edited by Nora Engel, experts in the field cover the most up to […]
High Def DNA Methylome Maps Point Out Male and Female Germ Cell DifferencesFebruary 20, 2013What sets males and females apart? Actually, let’s not head there, but how about at the methylome level? Quite a bit it appears. In a recent paper, researchers from Japan report that male and female primordial germ cells (PGCs) have different methylomes during development—at least in mice. While these germ cells divide and move to […]
EpiGenie Reviews: RNA Interference and Viruses – Current Innovations and Future TrendsFebruary 11, 2013RNA interference (RNAi) was first discovered in 1998 and has sparked new innovations and novel research tools for biological research ever since. RNAi has the scientific community buzzing because of it’s huge potential to tackle some of our most dreaded viral infectious diseases, like hepatitis C virus (HCV) and human immunodeficiency virus (HIV). But there […]
