Bone sialoprotein.
The search for a protein nucleator of hydroxyapatite crystal formation has been a focus for the isolation and characterization of the major non-collagenous proteins in bone. Of the proteins characterized to date, bone sialoprotein (BSP) has emerged as the only bona fide candidate for nucleation. BSP is a highly glycosylated and sulphated phosphoprotein that is found almost exclusively in minera...
متن کاملHuman Bone Sialoprotein
A cDNA encoding the human bone sialoprotein was isolated from a X Zap expression library (made from cultured human bone cell poly(A)+ RNA) using radiolabeled rat bone sialoprotein cDNA (Oldberg, A., and Heinegard, D. (1988) J. Biol. Chem. 263, 1943019432) as a probe. A 5’ 1-kilobase EcoRI fragment of the purified 3-kilobase clone was sequenced and found to contain the entire protein-encoding re...
متن کاملCardiotonic agent milrinone stimulates resorption in rodent bone organ culture.
The cardiotonic agent amrinone inhibits bone resorption in vitro. Milrinone, an amrinone analog, is a more potent cardiotonic agent with lower toxicity. In contrast to amrinone, milrinone stimulated resorption in cultures of neonatal mouse calvaria and fetal rat limb bones. Threshold doses were 0.1 microM in calvaria and 0.1 mM in limb bones; maximal stimulation occurred in calvaria at 0.1 mM. ...
متن کاملHuman recombinant transforming growth factor alpha stimulates bone resorption and inhibits formation in vitro.
Human recombinant transforming growth factor alpha (TGF alpha), which binds to the epidermal growth factor (EGF) receptor and causes several biological effects similar to those caused by EGF, was compared with murine EGF for its effects on a number of parameters of bone cell metabolism. TGF alpha stimulated bone resorption in two organ culture systems, the fetal rat long bone and neonatal mouse...
