Cas9: The Ultimate Gene Driving MachineMarch 30, 2015Add one more to all the amazing things CRISPR can do: it is also the ultimate driving machine. Provided, of course, that you are a gene, and that your destination is any chromosome where you do not currently reside. Gene Drives Spread by Overwriting Alleles A gene drive is when a gene on one chromosome […]
H3K9me3: The Genomic Pacifier That Silences SINEsMarch 30, 2015Kids can be hard to handle, between dealing with drawing on the walls and public temper tantrums; therefore all parents need a successful tactic for keeping them under control. Short INterspersed Elements (SINEs) are like the chaotic kids of the genome. These repetitive sequences make up about 11% of our genome and because of their […]
Transdifferentiation Strategy Weeds Out Immature Cancer CellsMarch 29, 2015Every gardener knows the key to successful weeding; extract the entire root because even a small section can regenerate the whole plant. When treating cancer, doctors are faced with the same problem. Immature cancer stem cells often escape treatment and repopulate the tumor, despite its successful elimination by radio or chemotherapy. In a new take […]
The Long Route of MeCP2 in TranscriptionMarch 24, 2015A number of teams have already spent time in trying to uncover the path that leads from MeCP2 disruption to Rett syndrome, a severe neurodevelopmental disorder in the autism spectrum. Adding detail to MeCP2’s repressive function, a team led by Michael Greenberg gathered data from MeCP2 mouse mutants and patient samples, finding an unexpected clue in long-gene […]
Hearts on ChipsMarch 24, 2015Chips, in most incarnations, are bad for the heart. Whether you’re frying them, baking them into cookies, or carrying one on your shoulder, chips are not cardiologist-approved. A new paper from Kevin Healy’s lab aims to mend this relationship with a microfluidic chip that is able to coax human induced stem cells into beating 3D […]
