Research

Research Summary/Interests

Dr. Lowe’s laboratory investigates cellular and molecular mechanisms underlying skeletal muscle deterioration that occur with age, injury, and disease. We are particularly interested in how the loss of estradiol causes muscle weakness and impaired regeneration of injured muscles. Our studies point toward the deterioration of myosin function and satellite cells as two of the culprits. We are highly collaborative in muscular dystrophy research having published with eight other UMN muscle biologists. Our studies often have a flavor of exercise science and preventative medicine as well as rehabilitation. Trainee research experiences are enriched by the collaborative nature of our work that intersects muscle research from fields of biochemistry, physiology, biophysics, engineering, molecular and stem cell biology, pathology, endocrinology, immunology, and bone biology.
