Vitamin D derived from the diet or produced in the skin is converted to its active form by two sequential hydroxylation reactions (1, 2). The first occurs in the liver, forming 25-hydroxyvitamin D3...

Renal 25-hydroxyvitamin D3-1-hydroxylase (1-hydroxylase) enzyme activity in rats is known to be increased by parathyroid hormone (PTH), hypophosphatemia, and hypocalcemia. Thus, enzyme activity is markedly increased in vitamin D-deficient states, but

Using an experimental rat model, this study was undertaken to assess the effects of a short-term application of high dose 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] on calcium homeostasis, cancellous bone formation, and numbers of osteoblast precursors

The changes in plasma calcium, phosphate, and parathyroid hormone (PTH) levels that accompany 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] administration to experimental animals represent major obstacles to determining the precise role that 1,25(OH)2D3 pla

The hypocalcemia that accompanies vitamin D deficiency is a major obstacle to proper interpretation of the role(s) of vitamin D metabolites in Ca-sensitive tissues. This paper describes the development and complete characterization of a dietary regim

Despite numerous attempts, no reliable dietary regimen exists to achieve vitamin D deficiency (-D) in rats without attendant changes in plasma parathyroid hormone (PTH), Ca, or phosphate. This represents an important obstacle to proper investigations
