Abstract

Rats were raised in the absence of vitamin D in utero and throughout post-fetal life and neither 1,25-dihydroxyvitamin D3 nor related metabolites were detected in serums. No changes were observed in the relative amount of extractable noncollagenous bone proteins (NCP) in rachitic compared to vitamin-D-repleted animals. As expected, the relative levels of the mineral-bound, serum-derived albumin and α2-HS glycoprotein were unaffected in bones of rachitic animals. Interestingly, the vitamin D deficiency also did not have dramatic effects on several bone cell-derived noncollagenous proteins including: bone proteoglycans I & 11, bone sialoprotein li osteonectin, and osteocalcin. In contrast to the proteoglycans, the bone sialoprotein II and osteonectin were found in the nonmineral compartment of the rachitic animals, presumably bound to the wide osteoid seam.
