Outline of Final Research Achievements |
Notch signaling modulates skeletal formation and pathogenesis of osteoarthritis (OA) through induction of catabolic factors. OA development was suppressed when Hes1 was deleted from articular cartilage after skeletal growth in type II collagen (Col2a1)-CreERT;Hes1fl/fl mice. ChIP-seq identified Hes1-responsive regions in intronic sites of both genes; the region in the ADAMTS5 gene contained a typical consensus sequence for Hes1 binding. We further identified calcium/ calmodulin-dependent protein kinase 2δ (CaMK2δ) as a cofactor of Hes1; CaMK2δ was activated during OA development, formed a protein complex with Hes1, and switched it from a transcriptional repressor to a transcriptional activator to induce cartilage catabolic factors. Therefore, Hes1 cooperated with CaMK2δ to modulate OA pathogenesis through induction of catabolic factors.
