Outline of Final Research Achievements |
Fibrodysplasia ossificans progressiva (FOP) is a severely disabling heritable disorder of connective tissue characterized by progressive heterotopic ossification in various extraskeletal sites. FOP is caused by a gain-of-function mutation in ALK2, which causes up regulation of a transcriptional factor, Id1. We screened FDA-approval drugs for suppression of the Id1 promoter activated by the mutant ALK2 in C2C12 myogenic cells. We found that azelastine HCl (anti-histamine), Fluvastatin sodium salt (ant-hyperlipidemia), and Trimipramine maleate salt (anti-depressant) suppressed the Id1 promoter activity in a dose-dependent manner. These drugs also downregulated the expressions of the Id1-target osteoblastic genes such as alkaline phosphatase and osteocalcin.
