New gene-therapy approach could improve obesity treatment

Medical researchers at the University of Alberta have found a new way of using gene therapy to treat obesity. The treatment was successful, resulting in less weight gain, higher activity levels and decreased insulin resistance in lab models on a high-fat, high-sugar diet. Faculty of Medicine & Dentistry researcher Jason Dyck, who works in the Department of Pediatrics and the Department of Pharmacology, published his findings this week in the peer-reviewed journal Nutrition and Diabetes. His team found a way to deliver the obesity treatment via DNA as opposed to a virus, which has had limited success in the past, especially over the long term. The results they demonstrated corroborated findings by other researchers who conducted short-term studies or used more risky methods of gene delivery.
