| Outline of Final Research Achievements |
Sclerostin, encoded by SOST, is a secretory protein that suppresses osteogenesis by inhibiting Wnt signaling. However, the regulatory mechanism underlying SOST expression remains unclear. We identified four transcription factors, ATF3, KLF4, PAX4, and SP7 that induced SOST expression and sclerostin secretion in human dermal fibroblasts. Parathyroid hormone suppressed the induced SOST and sclerostin, whereas hypoxia and prostaglandin E2 increased the induced SOST. This model may contribute to elucidating the regulatory mechanisms underlying SOST expression and advancing drug development for metabolic bone diseases.
