ST5 Positively Regulates Osteoclastogenesis via Src/Syk/calcium Signaling Pathways.

For physiological or pathological understanding of bone disease caused by abnormal behavior of osteoclasts (OCs), functional studies of molecules that regulate the generation and action of OCs are required. In a microarray approach, we found the suppression of tumorigenicity 5 (ST5) gene is upregulated by receptor activator of nuclear factor-κB ligand (RANKL), the OC differentiation factor. Although the roles of ST5 in cancer and β-cells have...
