Outline of Final Research Achievements |
In some pathological conditions, skeletal muscle tissues show heterotopic ossification. Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder characterized by progressive heterotopic ossification in skeletal muscle due to a genetic mutation of ALK2, a BMP type I receptor. We found that Smad9 has unique functions among substrates of BMP receptors, such as Smad1 and Smad5. A component of NFkB signaling, p65, suppressed the Smad-dependent BMP activity by direct interaction with Smad4. Mutant ALK2 identified in patients with FOP were synergistically activated by BMP type II receptors in a kinase activity-dependent manner. These results suggest that the heterotopic ossification caused by muscle trauma in FOP might be induced by ligands activated indirectly by inflammatory reactions in the skeletal muscle.
