Cyclosporine A inhibits bone resorption in cultured neonatal mouse calvaria.
The effect of the immunosuppressive agent cyclosporine A (CsA) on the resorption of neonatal mouse calvaria was examined in vitro. CsA, at concentrations of 10(-7) to 3 X 10(-5) M, inhibited bone resorption produced by 10(-8) M parathyroid hormone, 3 U/ml of mouse recombinant interleukin-1,5 X 10(-7) M prostaglandin E2, 14 U/ml of thrombin, 5 micrograms/ml of bacterial lipopolysaccharide or 10(...
متن کاملPorphyromonas gingivalis infection increases osteoclastic bone resorption and osteoblastic bone formation in a periodontitis mouse model
BACKGROUND Porphyromonas gingivalis has been shown to invade osteoblasts and inhibit their differentiation and mineralization in vitro. However, it is unclear if P. gingivalis can invade osteoblasts in vivo and how this would affect alveolar osteoblast/osteoclast dynamics. This study aims to answer these questions using a periodontitis mouse model under repetitive P. gingivalis inoculations. ...
متن کاملParathyroid hormone-like effects of rainbow trout Stannius products on bone resorption of embryonic mouse calvaria in vitro.
Products of the Stannius corpuscles (SC) of rainbow trout were tested in an established PTH bioassay involving bone resorption in embryonic mouse calvaria. Aqueous extracts from Stannius corpuscles (SC-homogenate) showed a bone-resorbing activity comparable to PTH in 24-h cultures of calvaria, indicated by a dose-dependent stimulation of lactate production and of calcium, phosphate as well as b...

متن کاملPhosphatidylcholine metabolism in neonatal mouse calvaria.
Phosphatidylcholine metabolism was examined in neonatal mouse calvaria in vitro. Incorporation of choline into phosphatidylcholine was slow in this tissue. At 2 h after a pulse of [methyl-3H]choline only 30% of the tissue radioactivity was in the organic phase. Chromatography of the aqueous phase of the tissue extract revealed that more than half of the radioactivity was present as choline at t...
