title: Inhibitory effects of egg yolk soluble protein on bone resorption.
abstract: We determined the effects of yolk water-soluble protein (YSP) on bone resorption. YSP potently suppressed osteoclastogenesis from bone marrow-derived precursor cells driven by tumor necrosis factor-alpha (TNF-alpha). YSP (200 microg/ml) abolished the formation of tartarate-resistant acid phosphatase (TRAP)-positive osteoclasts. Furthermore, TNF-alpha induced TRAP activity was greatly inhibited by YSP (100 microg/ml) treatment. Our results suggest that YSP has therapeutic potential for bone-erosive diseases.
