HpaII and MspI Strike Again in 5hmC Sequencing with HMST-SeqMarch 24, 2013It’s hard to tell some things apart—for instance, with her new haircut, Miley Cyrus could almost be mistaken for Pink. Well, almost. Anyhow, if you’re trying to tell 5-methylcytosines (5-mCs) from 5-hydroxymethylcytosines (5-hmCs) from each other, you’re in luck because there’s a new method for that—one that’s inexpensive and selective. Sure, some methods for doing […]
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 […]
Chromatin Modifications in EnhancersMarch 20, 2013Enhancers serve as distal regulators of gene expression, but insights into the precise mechanisms of enhancer chromatin modifications are still lacking. In this recent review, Calo and Wysocka summarized various enhancer-associated modifications and propose how these modifications regulate enhancer activity during development. Here are some of the key topics discussed: The Enhancer Chromatin Landscape Enhancers […]
The 3D Genome: A Review into Genomic Organization and its Key PlayersMarch 20, 2013Our genome is not linear. Nope, it’s a three-dimensional labyrinth of regulatory nooks and crannies . Gibcus and Dekker recently published this free review that looks at the spatial hierarchy of genomic organization and how it modulates gene expression. This is a great resource for those of you looking to beef up your understanding of […]
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 […]
