They say hindsight is 20/20, but for those of us looking over at a lifetime of memories, things might seem a little blurrier through our aging eyes. That’s because, unlike the fine wines, delectable whiskies, and smelly cheeses that we love to catabolize, the human epigenome tends not to age very well and a wide […]

There’s More Than One Way to Scare A Mouse: Z-DNA and ADAR1 Add to Fear Extinction
There’s already some histone modifications, and a dash of non-coding RNA, but new research adds another ingredient to the epigenetic recipe of fear memories and it’s called Z-DNA! Z-DNA occurs when the DNA molecule forms a left-handed double helix rather than the right-handed structure that we’re used to. This inside-out conformation is enriched at actively […]
Micro-C and Single-Cell Hi-C Provide Macro Chromosome Conformation Insights
Genome-wide chromosome conformation capture analyses, such as Hi-C, have provided us with snapshots of the large-scale spatial architecture of mammalian genomes, describing chromatin compartments, topologically associating domains (TADs), and CTCF– and cohesin-mediated chromatin loops in many cell types. However, the resolution of Hi-C-based protocols, limited by the size and uniformity of chromatin fragmentation, represents a […]
dCas9-ROS1 Cuts Out the Methylation Middlemen in Targeted DNA Demethylation
As the saying goes, the shortest path from A to B is a straight line and if you’re studying DNA demethylation, you know just how complicated things can get along the road from methylated to unmethylated cytosines. Mammals use Ten-Eleven Translocation proteins (TET) to oxidize 5mC, but the process creates pit stops that may be […]
Single-cell Multi-omic Maps of Germ Layer Enhancers – Deciphering The Best-laid Body-Plans of Mice and Perhaps Men?
A weekend away with a book of poetry, a mountain biking holiday, or perhaps a daring jewel heist……whatever your idea of a fun weekend is, a well-laid out, precise set of instructions usually help; in short, you need a plan! In the gastrulating mouse embryo, precise epigenomic and transcriptomic instructions dictate the differentiation of pluripotent […]
