My lab’s new paper in Communications Biology focused on high-grade pediatric glioma that have mutant histone variant H3.3 and we did something fairly novel that we are calling reciprocal CRISPR. Kids with these tumors have a near zero survival rate within a few years of diagnosis so we as a field desperately need something new to give them and their families real hope. Our paper is entitled, “Reciprocal H3.3 gene editing identifies K27M and G34R mechanisms in pediatric glioma including NOTCH signaling.” What we did in …Read More

Is it possible that CRISPR gene editing actually didn’t happen in many of the human embryos in that big Nature paper that made such news a couple weeks back? Some doubts have emerged that call the main conclusions of the paper into question and argue that more definitive studies are needed to be sure. An international team of top scientists led by first author Dieter Egli has responded via a preprint on Biorxiv to that Mitalipov team high-profile Nature paper on CRISPR gene editing of …Read More

2020 Update: early NgAgo reports have been mostly discredited and there is doubt on its function as a gene-editing method. What could be better than CRISPR for gene editing? A new genetic modification technology called NgAgo has some researchers really excited. How does it compare to CRISPR? I’ll admit it that as a scientist who works on genetics and genomics, I am really enjoying the power and simplicity of CRISPR-Cas9 type technology for genome editing. We are working with it extensively in my lab. One of …Read More

Editors note: This is a guest post from Caroline Simons who is attending the two Paris meetings on human gene editing. For more background on those meetings see here. By Caroline Simons There were just over a hundred participants at the workshop organized by the Federation of European Academies of Medicine, the UK Academy of Medical Sciences and the Académie Nationale de Médicine France. That number included experts in the fields of science, medicine, law and bioethics. They came from Europe, the US and …Read More
