Sequences in the human parathyroid hormone gene that bind the 1,25-dihydroxyvitamin D3 receptor and mediate transcriptional repression in response to 1,25-dihydroxyvitamin D3.

Abstract excerpt

1,25-dihydroxyvitamin D3 [1,25(OH)2D3], plays an important role in the regulation of mineral ion homeostasis. As well as being the major steroid hormone that regulates calcium metabolism, 1,25(OH)2D3 suppresses transcription of the gene encoding parathyroid hormone, a peptide that plays a dominant role in regulating extracellular calcium levels. To identify DNA sequences that may mediate this transcriptional...
