 note = {P(論文), Parathyroid hormone (PTH) acts on bone and kidney by binding to PTH/PTH-related protein receptor (PTH1R) and regulate calcium (Ca) and phosphorous (P) homeostasis. This experiment was undertaken to investigate the effect of Ca and vitamin D restriction (-Ca-D) diet on PTH1R mRNA expression in the major PTH target tissues such as bone and kidney. Rats fed -Ca-D diet showed significant decrease in serum Ca and P on day 14 and day 7, respectively. Serum PTH and 1, 25 dihydroxyvitamin D_3[1,25(OH)_2D_3] markedly increased on day 14 and day 1, respectively. Renal VitaminD-1 a-hydroxylase activities increased slightly during day 1-7 and markedly during day 14-35. PTH1R mRNA abundance determined by Northern blot analysis did not change in bone and kidney, when rats were fed -Ca-D diet for up to 14 days. These results suggest that down-regulation of PTH1R in PTH target tissues is due to degradation, internalization and desensitization of the receptor protein without transcriptional attenuation.},
