CRISPR-Cas9 Gene Editing of Human Embryos: A Look at the ScienceApril 28, 2015Unless you were on Mars or in the middle of a Netflix binge, you couldn’t have missed the paper that has been hitting the headlines all over the world this week – the first example of the genetic modification of human embryos. The study led by Junjiu Huang (Sun Yat-sen University, Guangzhou) used CRISPR-Cas9 gene […]
Boosting Transcription with a Little Help from Histone CrotonylationApril 24, 2015Every auto enthusiast knows that if you want to maximize the performance of your car, you’ve got to have the right parts in the right combination. While sometimes you may have to completely rebuild your engine, other times all you need is to upgrade to the latest system components. In a recent article published in […]
Pioneering Transcription Factors Wiggle Towards PluripotencyApril 24, 2015Canoes, camels, cars and catamarans have carried human pioneers far and wide; taking us to undiscovered lands to encounter unseen beauty, encouraged by the hope of fame, glory, and a lust for adventure. How pioneer transcription factors brave the inhospitable exterior of a compacted DNA-histone complex to induce transcription of tightly guarded genes is, however, […]
Human Preimplantation Embryos Go RetroviralApril 24, 2015Our genomes are littered with tales of our evolutionary past, including infections from retroviruses that have left their mark in the vast expanses of the human genome. While most of the endogenous retroviruses (ERVs) have lost their protein coding potential, a class of human specific ERVs (HERVs) still possess intact open reading frames. Inspired by […]
At Risk of Autistic Offspring? Sperm DNA Methylation May Hold the AnswerApril 23, 2015Finding the origin of complex disease is no easy task but now it seems a seminal breakthrough has occurred. Andrew Feinberg and team at the John Hopkins University Center for Epigenetics have found a DNA methylation pattern in the sperm of fathers with an increased risk of fathering autistic children that is also present in brains […]
