Calcifediol 0-25 parathyroid hormone Rattus norvegicus 130-133 2560171-1 1989 Previous work from this laboratory has demonstrated that 25(OH) vitamin D3 [25(OH)D3] acutely suppresses the phosphaturic action of parathyroid hormone (PTH) and interferes with the PTH-induced activation of adenylate cyclase (AC). Calcifediol 76-84 parathyroid hormone Rattus norvegicus 132-151 2821148-6 1987 Parathyroid hormone significantly increased the conversion of 25-hydroxyvitamin D3 to 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) by renal slices from young but not adult or old animals. Calcifediol 62-82 parathyroid hormone Rattus norvegicus 0-19 3004922-0 1986 Human parathyroid hormone inhibits renal 24-hydroxylase activity of 25-hydroxyvitamin D3 by a mechanism involving adenosine 3",5"-monophosphate in rats. Calcifediol 68-88 parathyroid hormone Rattus norvegicus 6-25 3004922-1 1986 The in vivo effect of PTH on renal 24-hydroxylase activity of 25-hydroxyvitamin D3 (25OHD3) was examined in vitamin D-deficient thyroparathyroidectomized rats by a recently developed sensitive in vitro assay of 25OHD3-hydroxylases using rat kidney homogenates and by an in vivo assay measuring the accumulation of tritiated metabolites in plasma 5 h after injection of 25OH[3H]D3. Calcifediol 62-82 parathyroid hormone Rattus norvegicus 22-25 6317364-1 1984 Renal production of 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] from 25-hydroxyvitamin D3 (25OHD3) is increased by PTH. Calcifediol 65-85 parathyroid hormone Rattus norvegicus 111-114 6981502-1 1982 In young rats, PTH markedly stimulates the renal conversion of 25-hydroxyvitamin D3 (25OHD3) to 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3], the biologically active form of vitamin D3. Calcifediol 63-83 parathyroid hormone Rattus norvegicus 15-18 6320659-0 1984 Effect of PTH and 1,25(OH)2D3 on renal 25(OH)D3 metabolism, adenylate cyclase, and protein kinase. Calcifediol 39-47 parathyroid hormone Rattus norvegicus 10-13 6320659-1 1984 The purpose of these studies was to characterize the action of PTH and 1,25(OH)2D3 on the renal metabolism of 25(OH)D3 to 1,25(OH)2D3 and 24,25(OH)2D3. Calcifediol 110-118 parathyroid hormone Rattus norvegicus 63-66 6320659-6 1984 1,25(OH)2D3 also blocked the effect of PTH (5.0 U/ml) on renal 25(OH)D3 metabolism. Calcifediol 63-71 parathyroid hormone Rattus norvegicus 39-42 6320659-8 1984 These studies demonstrate that PTH may act directly on the kidney to modulate renal 25(OH)D3 metabolism and that this action can be inhibited by 1,25(OH)2D3. Calcifediol 84-92 parathyroid hormone Rattus norvegicus 31-34 196836-1 1977 Teh stimulatory effect of parathyroid hormone (PTH) on renal 1alpha-hydroxylation of 25-hydroxyvitamin D3 (25-OH-D3) was studied in thyro-parathyroidectomized (TPTX), vitamin D-deficient rats into which bovine PTH, theophylline, cAMP or dibutyryl cAMP (dbcAMP) was constantly infused. Calcifediol 85-105 parathyroid hormone Rattus norvegicus 26-45 196836-1 1977 Teh stimulatory effect of parathyroid hormone (PTH) on renal 1alpha-hydroxylation of 25-hydroxyvitamin D3 (25-OH-D3) was studied in thyro-parathyroidectomized (TPTX), vitamin D-deficient rats into which bovine PTH, theophylline, cAMP or dibutyryl cAMP (dbcAMP) was constantly infused. Calcifediol 107-115 parathyroid hormone Rattus norvegicus 26-45 4812447-16 1974 These results indicate that 25HCC enhances tubular reabsorption of phosphorus in rats, only in the presence of either endogenous or exogenous circulating PTH, but not in its absence and thus imply a PTH-dependent mechanism of 25HCC action on the kidney. Calcifediol 28-33 parathyroid hormone Rattus norvegicus 154-157 4812447-16 1974 These results indicate that 25HCC enhances tubular reabsorption of phosphorus in rats, only in the presence of either endogenous or exogenous circulating PTH, but not in its absence and thus imply a PTH-dependent mechanism of 25HCC action on the kidney. Calcifediol 28-33 parathyroid hormone Rattus norvegicus 199-202 4812447-16 1974 These results indicate that 25HCC enhances tubular reabsorption of phosphorus in rats, only in the presence of either endogenous or exogenous circulating PTH, but not in its absence and thus imply a PTH-dependent mechanism of 25HCC action on the kidney.
