Vitamin D metabolism in pregnant rabbits: differences between the maternal and fetal response to administration of large amounts of vitamin D3.

abstract：:The alphaVbeta3 integrin is an important determinant of IGF-I-stimulated receptor phosphorylation and biological actions. Blocking ligand occupancy of alphaVbeta3 with the distintegrin echistatin reduces IGF-I-stimulated receptor phosphorylation, and it inhibits cellular migration and DNA synthesis responses to IGF-I....
