The steroid hormone 1 alpha,25-dihydroxyvitamin D3 (1 alpha,25-(OH)2D3) generates biological responses via both genomic and nongenomic mechanisms. This article reports the biological profile of four(More)
1Alpha,25(OH)2D3 is an important negative regulator of parathyroid hormone (PTH) gene transcription. In parathyroid cells, as in other target tissues, 1alpha,25(OH)2D3 is degraded by side chain(More)
The hormone 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) generates biological responses via both genomic and nongenomic mechanisms. This article addresses activity differences between the 6-s-trans(More)
The secosteroid hormone 1alpha,25-dihydroxyvitamin D3 [1alpha,25(OH)2D3] is metabolized into calcitroic acid through the carbon 24 (C-24) oxidation pathway. It is now well established that the C-24(More)
The steroid hormone 1 alpha,25-dihydroxyvitamin-D3 [1 alpha,25(OH)2D3] stimulates biological responses via both genomic mechanisms and nongenomic mechanisms (opening of voltage-gated Ca2+ channels).(More)
