SunTag Casts Light on iPSC ReprogrammingFebruary 6, 2018While the DNA editing function of CRISPR/Cas9 systems may appear to hog the limelight, we believe that a new SunTag approach for CRISPR/Cas9-mediated induced pluripotent stem cell (iPSC) reprogramming via epigenome editing deserves its day in the sun! The exciting reprogramming strategy utilizes an endonuclease dead Cas9 (dCas9) fused to a repetitive protein scaffold known […]
Like a Fine Wine, Histone Variant H2A.Z Represses Memories and Accumulates with Age!February 6, 2018While aging works wonders for the taste of our ever-accumulating wine collection, the passage of the years is not as kind to our memories! To fully decipher the processes underlying learning and memory differences in the aging brain, the lab of Iva Zovkic at the University of Toronto Mississauga (Canada) recently expanded on past work […]
Epigenetic and Mitochondrial Clocks Synchronously Accelerate with Bipolar DisorderJanuary 18, 2018A wise man once said that time is relative, and while physics was on his mind, it seems that biology should have been as well. For instance, patients with bipolar disorder suffer from accelerated aging. However, examinations of telomere length have given mixed results, and this inspired the lab of Joao Quevedo in the University […]
H3K4 Mono-Methylation Means More at Most EnhancersJanuary 16, 2018People can have some pretty strange tastes. From mayonnaise on fries to syrup on spaghetti, there’s no accounting for personal preference. Proteins can have some interesting preferences too, where some regions of the genome look better than others. To get at these preferences, a recent publication from the Laboratory of Bing Ren at UC San […]
Single-Cell DNA Methylomes Reveal the Reprograming Secrets of Early Human EmbryosJanuary 16, 2018You’ve heard before that timing is everything, and this is doubly true in developmental biology. New research out of Fuchou Tang’s lab (Peking University, Beijing) singles in on the timing of methylation changes during embryonic development, and exposes the delicate epigenetic dance of global demethylation and targeted remethylation. Tang’s lab is no stranger to embryonic […]
