Dr. James Amatruda is studying the causes of cancer in one of the nation’s largest zebrafish aquariums at UT Southwestern Medical Center. Amatruda got a boost last week when Hyundai Hope On Wheels awarded a $250,000 grant to the Children’s Medical Center Foundation to support his work. As a Hyundai Scholar, Amatruda will use the funds to study rhabdomyosarcoma, a pediatric cancer of the muscle and soft tissue.
