Polymerases are Key Influencers in Homologous Recombination EventsNovember 5, 2014Gene targeting by homologous recombination can be variable and researchers are itching to understand what key factors underlie variable success in editing experiments. Could it be an unfavorable chromatin environment, repetitive sequences, or maybe just bad luck? An unrelenting group of researchers at the University of Washington recently set out to shed some light on the genomic elements […]
in vivo CRISPR Takes Aim at Key DNA Methylation Players in the BrainOctober 31, 2014Adding to the ever growing potential of genome editing, one of the latest breakthroughs from the lab of Feng Zhang at the Broad Institute of MIT and Harvard puts CRISPR/Cas9 to the test with an interesting research trifecta of: in vivo genome editing focused on the brain genome editing that targeted DNA methylation machinery including key readers and writers. both […]
A CRISPR Way to Create FusionsOctober 31, 2014As CRISPR continues to evolve into the laboratory version of a Swiss Army Knife, it’s not surprising that another innovative research team have used the approach in a slick way; in this case to engineer of oncogenic chromosomal rearrangements. Chromosomal rearrangements, gene fusions, deletions and inversions are classical hallmarks of cancer. These re-arrangements lead to […]
Epigram: Predicting the Human Epigenome from DNA MotifsOctober 16, 2014There’s no denying the power of technology in our lives, whether it be your latest and greatest iPhone bending in your pocket or it be getting the technology to do something more useful, like predict the entire epigenome and how it functions in the regulation of gene expression. We’ve always loved a good tool and/or […]
Enhancers Share their Genome Editing Turn Ons (and Offs)October 13, 2014Tired of not knowing what really turns an enhancer on? You’re not alone, but luckily an inquisitive team of researchers out of Cambridge spent some serious time targeting enhancers by throwing some genome editing wizardry at them. The team, led by Pentao Liu, systematically compared how the TALE effectors and CRISPR targeting tools fare in […]
More Cleavage: CRISPR Cas9 Can Target RNA TooOctober 11, 2014Targeted genome editing using CRISPR/Cas9 has been on the forefront of genome editing research lately. The Cas9 system is effective, efficient, and reliably specific in its approach to cleavage of nucleotides of interest. The catalytic activity of Cas9 depends on its ability to recognize short DNA sequences called the protospacer adjacent motif (PAM). Although it’s […]
Turning the Tables on Bacteria with CRISPR-Cas AntimicrobialsOctober 11, 2014Fighting pathogenic bacteria can be as frustrating as being an early adopter of electronic gadgets. You grab the latest smart phone, and the following day leaks of the next generation are hitting the net. The broad-spectrum nature of many antibiotics is partially to blame as they destroy our friendly bacteria and contribute to resistance. Lucky for […]
CRISPR/Cas9 Get Upgraded sgRNA TargetingAugust 12, 2014The Crispr/Cas9 genome editing system has risen to fame so quickly it appears to be suffering from a case of the bends. Researchers at Johns Hopkins University however have just given it a bit more room by to breathe by overcoming an inherent bias that limits sequences the system can target. By modifying the short guide […]
Patient Specific iPSCs Team Up with CRISPR/Cas9August 12, 2014Some villains are so tough that it might take a few heroes to take them on. β-thalassemia is just that evil, an all too common genetic disease at the worldwide level. Caused by simple mutations in the hemoglobin beta (HBB) gene, this beast is Mendelian in nature. Which makes a perfect target for CRISPR/Cas9, a duo with […]
Gazing at Your Local Epiproteome with CRISPR-ChAP-MSAugust 4, 2014For those of you who were thinking the CRISPR/Cas9 system was just limited to genome editing, think again because the story just got a new twist. Almost like combining the bullet speed of Superman with the hi-tech gadgets of Batman, Alan Tackett and colleagues come up with a new tool to look at all the […]
