The latest challenge is protecting damaged tissue immediately after a heart attack with the help of base editing (see the paper published in Science by Eric Olson’s group at the University of Texas Southwestern Medical Center). But there are hundreds of devastating diseases that affect the heart or other muscles and are caused by mutations that could be fixed by CRISPR-based tools (see this paper in Science Trsnslational Medicine for example). From Duchenne dystrophy to cardiomyopathies, some preliminary results are very encouraging.

“Exciting news! Our partner, Dr. Eric Olson and his team at Exonics published their research on increasing dystrophin restoration of 92% in the hearts of dogs. While they have a long way to go, their dramatic research gives hope to all families affected by Duchenne!”. This is how the patient advocacy group CureDuchenne announced the CRISPR breakthrough just published in Science. Continue reading
