Cas9 Nickase-Mediated Contraction of CAG/CTG Repeats in Vivo is Accompanied by Improvements in Huntington's Disease Pathology
Expanded CAG/CTG repeats cause over 15 different diseases that all remain without a disease-modifying treatment. Because repeat length accounts for most of the variation in disease severity, contracti...

Ever wondered why there are interruptions in expanded repeats? Here are our thoughts: www.sciencedirect.com/science/arti... (We think the answer is double-strand break repair) PS: I’ve not been on here for a bit, but I needed to do some self promotion.

Interruptions impact clinical features of repeat expansion diseases, but how are they gained and lost?
Interruptions within expanded tandem repeats reduce somatic expansion and alter the severity of the resulting diseases. Consequently, much has been do…

We are lucky to be among the funded projects (We’re in good company!) We’re de-risking our gene editing approach for expanded repeat disorders (e.g. Huntington’s disease, myotonic dystrophy…). One step closer to the clinic! www.ukdri.ac.uk/news-and-eve...

I’ll say it again because it is important. American scientists will not en masse leave the US. This is for several reasons. Here are a few. For those already on the fence, we are recruiting a new centre director. www.ukdri.ac.uk/vacancies/ce...

If you have been affected by the fires in LA, or are concerned about your ability to keep precious Drosophila strains going during the latest funding crisis, we will host your strains as a backup. Please email me. Please amplify. If you are also able to host fly strains, add your name as well.

In a study of brain cells from mice and humans, researchers have uncovered a 'chemical metronome' which tells us when its time to sleep.😴 The scientists say this could have implications for treating jetlag and sleep disorders.👇 www.imperial.ac.uk/news/258953/...
