m6A Modification Protects Against Heat ShockNovember 13, 2015When exposed to high temperatures, cells behave much as we would on a hot summer’s day. Cell division, and most energy-consuming activities, come to a standstill (a bit like the human equivalent of lying perfectly still on a sunbed with a mojito in hand). Yet, despite the general repression of translation, genes encoding protective heat […]
CRISPR Takes the PERV Out of Pig OrgansNovember 13, 2015Nobody likes a PERV – they just make everyone uncomfortable. Porcine (pig) Endogenous RetroViruses (PERVs) are a creepy concern when it comes xenotransplantation (transplanting organs from a different species), since the perks of not having to wait for an organ transplant take a hit when PERVs get all up in your genome. In order to […]
Different Pluripotent Stem Cells Remain Functionally SimilarNovember 12, 2015Coke vs. Pepsi, Domino’s vs. Pizza Hut, Bud vs. Miller. Could you tell the difference them in a taste test, given that they are made in a slightly different way with slightly different starting materials? And in the end, if each option does the job they were designed to do (filling bellies!), will any slight […]
New Cas Effectors Inject Fresh Talent Onto CRISPR StageNovember 12, 2015Poor Cas9. Â If CRISPR were a new music trend, Cas9 would the band that was playing CRISPR long before it was cool, rode the CRISPR wave to stardom, alienated its fans with copyright battles, and is already under threat from the new kids. Less metaphorically, Cas9 is an enzyme that uses RNA spacers (crRNAs) transcribed […]
Linking RNA Modifications and Stem Cell PluripotencyNovember 12, 2015Recent studies reported here at Epigenie have identified N6-methyladenosine (m6A) as a highly dynamic RNA modification that influences all aspects of RNA biology. Furthermore, an interesting study in mouse and human embryonic stem cells (ESCs) has indicated a role for N6-methyladenosine in the switch between ESC pluripotency and differentiation. Cool stuff indeed, but whate regulates N6-methyladenosine deposition […]
