Plotting the Path to Pluripotency Uncovers Key Role of DNA MethylationDecember 29, 2014If you’ve read our recent piece ‘Reprogramming Roadmap Reveals Fuzzy New Stem Cells‘ you’ll already know how “Project Grandiose” [1, 2], the brainchild of Andras Nagy, identified a new pluripotent state (the F-class stem cell). While the discovery of this new class is thrilling, the main purpose of this grand project was to uncover the […]
Genome Editing TimelineDecember 18, 2014Since its inception, the field of genetic engineering has introduced DNA to plenty of nips, tucks, and modifications all in the name of science. The latest evolution of these, genome editing, might be the most promising. Follow our favorite highlights in this rapidly moving application.
A “Grandiose” Project Provides a Fuzzy New Future for iPSC ResearchDecember 17, 2014Induced pluripotent stem cell (iPSCs) research burst on to the scene in 2006 with a paper which has since spawned thousands of studies and has proved to be a quantum leap for regenerative medicine. This reached a crescendo this year when a Japanese patient became the first recipient of retinal cells generated from iPSCs made […]
Histone H2A.Z Subunit Exchange Controls MemoryDecember 17, 2014Memory is one fancy cellular function that seems to be the niche of the epigenome. Through it a cell can remember its identity and past exposures. But what about that other type of memory? Ya know, neuroepigenetic memory. We’ve already seen that histone methylation has a role in long-term memories and altered histone acetylation (H4K12) is involved […]
Vitamin C Promotes ESC Self-Renewal by Modulating miRNA ExpressionDecember 16, 2014We all know “an apple a day, keeps the doctor away”, but it requires a lot of discipline to ensure that our diet contains enough vitamins. This holds especially true for the daily vitamin C uptake. Unfortunately, humans (and – for some mysterious reason – guinea pigs) lost the ability to synthesize this now essential […]
