Gene Therapy In Mice Builds Muscle, Reduces Fat
Exercise and physical therapy often are recommended to help people who have arthritis. Both can strengthen muscle — a benefit that also can reduce joint pain. But building muscle mass and strength can take many months and be difficult in the face of joint pain from osteoarthritis, particularly for older people who are overweight. A new study in mice at Washington University School of Medicine in St. Louis, however, suggests gene therapy one day may help those patients.
The research shows that gene therapy helped build significant muscle mass quickly and reduced the severity of osteoarthritis in the mice, even though they didn’t exercise more. The therapy also staved off obesity, even when the mice ate an extremely high-fat diet.
