| abstractText | The klotho gene product and stanniocalcin (STC) 1 and 2 are recently identified molecules implicated in calcium and phosphorus homeostasis. In the present study, we investigated the regulation of STC1 and STC2 gene expression in the kidney by klotho gene expression. Mice deficient in klotho expression (klotho mice) have hypercalcemia and hyperphosphatemia, and increased renal gene expression of STC1 and STC2 compared with wild-type mice. Administration of vitamin D or CaCl(2) to wild-type mice causes upregulation of STC1 but STC2 gene expression is not altered significantly. On the other hand, treatment of klotho mice with low phosphorus diet results in partial decrease in STC2 gene expression with normalization of hyperphosphatemia. These findings indicate that klotho gene expression plays a crucial role in the regulation of renal stanniocalcin gene expression in vivo, at least partly, through the control of circulating calcium and phosphate concentrations. |
