Bacterial Kryptonite Uncovered in the Biological Dark Matter MinesJanuary 27, 2015Public health has a looming, if slow-simmering, crisis. Antibiotics, which revolutionized health care in the 20th century, are losing their punch. Evolution, it turns out, is pretty effective at producing things that don’t die. Accordingly, bacteria are evolving resistance to our antibiotic arsenal, and more people are suffering from previously-treatable infections. Meanwhile, the pipeline of […]
A Good Friend is Forever: DNMTs and Histone ComplexesJanuary 26, 2015It’s not always easy to find good friends, but recent work has found that the de novo DNA methyltransferases DNMT3A2 and DNMT3B1 are far from socially awkward. Baubec et al. from the Swiss team lead by Dirk Schübeler uncovered some companions of these DNMTs by profiling their binding in embryonic stem cells (ESCs) through streptavidin […]
Abcam’s Bisulfite-Seq High Sensitivity Kit Streamlines 5mC DetectionJanuary 26, 2015The new Bisulfite-Seq High Sensitivity Kit from the creative crew at Abcam, is a 2-in-1 package that weaves bisulfite conversion, and Illumina® sequencing library prep into the same process. This single kit can take you from sample DNA, to firing up a Bisulfite Sequencing (BS) run that same day. There’s No Such Thing as Too […]
The Latest and Greatest: A Genome-Editing Cautionary TaleJanuary 26, 2015Genome-editing techniques, including CRISPR-Cas9 and TALENs, have leapt into the limelight through their ability to perform feats such as creating genetically engineered monkeys, ‘curing’ a human related disease in mice, and taking out huge sections of a genome. The two systems are both based on nucleases, with the CRISPR-Cas9 system using the bacterially derived Cas-9 nuclease […]
Intergenerational Epigenetic Effects of Dad’s DietJanuary 23, 2015The effect of epigenetic marks across generations has helped bring epigenetics to the public eye like never before. The health implications are enormous and so is the contribution to basic science, particularly evolution. However, one important distinction is whether it is a true form of molecular inheritance, known as transgenerational epigenetic inheritance, or the shared effect […]
