Boosting CRISPR’s Editing EffectivenessMarch 31, 2015Unless you’ve been hiding under a rock you’ll know that CRISPR-Cas has been in the forefront of precise genome editing since its discovery in 1987 by Atsuo Nakata. However, as a technique it is not without shortcomings; while it has achieved a great deal of efficiency in the non-homologous end-joining (NHEJ) pathway, its ability to achieve […]
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 […]
iPSCs and CRISPR the Dynamic Duo of Regenerative MedicineMarch 23, 2015Laurel and Hardy, Peanut Butter and Jelly, Batman and Robin – can we now add iPSCs (induced pluripotent stem cells) and CRISPR to the list of famous duos? Linzhao Cheng (John Hopkins) certainly thinks so, and in a recently study his group have demonstrated how this combination of technologies may lead to an effective cell treatment […]
5hmC: a Helping Hand in Drug AddictionMarch 23, 2015While there’s no doubting that one month of continuous cocaine exposure is going to have an effect on the brain, it seems that some of the molecular culprits behind the response and long-term effects are 5hmC and the TET protein family. An international research team studying addiction via cocaine show that repeat exposure downregulates the TET machinery in the brain’s reward centre, the nucleus […]
Novel Primate- and Tissue Specific miRNAs with Dr Isidore RigoutsosMarch 17, 2015In this interview Dr Isidore Rigoutsos discusses his recent paper ‘Analysis of 13 cell types reveals evidence for the expression of numerous novel primate- and tissue-specific microRNAs‘ published in PNAS, February 2015. This paper shows the presence of many more miRNAs than previously thought and uncovers that the majority of these are in fact, cell-type […]
Our Favorite Findings from the Epigenomic RoadmapMarch 10, 2015For those of you with a keen eye, you’ll have already noticed the mass of Epigenomic Roadmap Studies published in Nature in February. In order to help you navigate this mountain of results we’ve highlighted some of our favorite findings from this collection of papers. Here’s our Top Five Findings: Enhancer-like Elements Take Center Stage in […]
