Research Abstract |
In this study, we analyzed the molecular mechanism of new regulation of vitamin D metabolism by thyroid hormone 13 in kidney. We demonstrated that thyroid hormone receptor betal and VDIR is important factor for the T3-dependent repression of the vitamin D synthesis enzyme Cyp27b1 gene. And, we found that the neither VDR nor Klotho was essential to the Cyp27bl gene control by T3, furthermore, we demonstrated that the phosphate transporter Npt2a gene play a critical role for the T3-dependent renal Cyp27bl gene repression using the Npt2a deficient mice.
