Using gene editing in a preclinical model, researchers at UT Southwestern Medical Center blocked the symptoms of a rare smooth muscle disease before they developed. Their findings, published in Circulation, could eventually lead to gene therapies for this and other genetic diseases affecting smooth muscle cells.

“Gene editing has been used in other disease contexts, but its application to inherited vascular diseases, particularly targeting smooth muscle cells in vivo, is still emerging. Our approach advances the field by demonstrating functional correction in a cell type that’s notoriously difficult to target,” said Eric Olson, Ph.D., Chair and Professor of Molecular Biology and a member of the Harold C. Simmons Comprehensive Cancer Center at UT Southwestern.

Dr. Olson co-led the study with Ning Liu, Ph.D., Professor of Molecular Biology, and first author Qianqian Ding, Ph.D., postdoctoral researcher, both members of the Olson Lab.
