On the island of genome editing, CRISPR is king. Rapidly rising from obscurity, the CRISPR nuclease Cas9 handily dispatched its predecessors, the clumsy TALENs and zinc-finger nucleases. Since then, there has been some strife within the royal family, as better Cas9 proteins and its relatives fought for dominance. Despite this internal turmoil, the CRISPR dynasty […]
Ever get that feeling that you forgot something? Well maybe you did, but it doesn't have to be recent epigenetics research if you scope out our Headlines each week.
At first glance the naked mole rat (NMR), or Heterocephalus glaber to his Latin speaking friends, might not win you over with its looks, but it truly is an amazing animal. It’s obviously comfortable in its own skin, but it also thrives in harsh environments, lacks pain sensitivity in its skin, has low metabolic and […]
While fine wine and aged cheese are culinary delights, some of us who dine on dairy often start to go a bit ‘sour’ with age and develop lactose intolerance. Thankfully, to aid our mental digestion of such a foul fate, a collaborative effort between Toronto and Lithuania has shown the molecular mechanism of why we can […]
Every researcher loves a good tool, and lately, it seems that CRISPR might be an even more modular tool than PCR. Attesting to the modularity of CRISPR/Cas9 is catalytically deactivated Cas9 (dCas9). dCas9 has the precision of Cas9, when combined with sgRNA, and can be fused to a modular effector domain that allows for extra […]
Cellular reprogramming represents the biological equivalent of spinning gold from straw: the generation of one therapeutically-desired cell type from another more abundant, and less useful, starting cell type. Following reprogramming, we can incorporate the resultant cells into new and effective patient-specific regenerative strategies. Reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) generates a […]
