- Organ System/Disease Focus
- Skeletal muscle growth and regeneration
- Aligned Research Focus
- Musculoskeletal Regeneration
A portion of my labs research uses mouse models to understand the factors that regulate the regenerative capacity of skeletal muscle. For instance, we recently created mice with satellite cell-specific and inducible knockout of a protein called TRIM28 and found that the skeletal muscles of these mice are unable to regenerate after a destructive injury. Our current efforts are now focused on defining how TRIM28 exerts this powerful regulatory function.
