Research Interest:
My laboratory is interested in understanding the pathological mechanisms underlying Duchenne Muscular Dystrophy (DMD). DMD is caused by mutations in the gene coding for dystrophin. Dystrophin is expressed at the membrane of muscle fibers and cardiac cells. Loss of dystrophin leads to chronic muscle damage and eventually muscle is replaced by fibrotic tissue. Patients succumb to heart or respiratory failure before their third decade of life.

Our laboratory is pursuing two research project. In project 1, we want to understand how loss of dystrophin leads to muscle degeneration and why some muscles are more affected than others. We have developed a proteomics-based protocol to isolate dystrophin from small amounts of muscle and then identify its interacting proteins. We have found new proteins that interact with dystrophin and provide new leads on its muscle-type specific functions. In Project 2, we want to understand the role of interstitial stem cells in the progression of muscle loss in DMD. We have found that stem cells from wild type muscle spontaneously differentiate into muscle. However, when we isolate these same stem cells from dystrophic muscle, only fibrotic cells are formed. We are currently studying pathways that regulate cell-fate choices in these stem cells with the goal of identifying compounds that can re-direct them to form muscle in dystrophic muscle.
