A schematic representation of bone resorption occurring at cellular and molecular level. a RANKL/RANK/OPG pathway and osteopontin in podosome formation. b Osteopontin binding to integrin αvβ3 leads to podosome formation and osteoclastic activity via Rac and NFAT pathway respectively. M-CSF (macrophage colony-stimulating factor), CSF-R (colony-stimulating factor receptor), RANKL (receptor activator of nuclear kappa-B ligand), RANK (receptor activator of nuclear kappa-B), OPG (osteoprotegerin), Src (proto-oncogene tyrosine-protein kinase), Syk (Spleen tyrosine kinase), Vav3 (vav guanine nucleotide exchange factor 3), Rac1 (Ras-related C3 botulinum toxin substrate 1), NFAT (nuclear factor of activated T cells)
