Calcitriol acts through both genomic and non-genomic mechanisms ( 2 ). (jcancer.org)
In genomic pathways, calcitriol binds to intracellular vitamin D receptor (VDR), which subsequently heterodimerizes with another nuclear receptor retinoid X receptor (RXR). (jcancer.org)
In addition, calcitriol has rapid effects that are independent of gene transcription regulation, which are defined as non-genomic effects and not mediated directly through steroid receptor-ligand-DNA interaction. (jcancer.org)
Calcitriol induces a number of non-genomic responses including rapid intestinal absorption of calcium, release of calcium from intracellular stores, opening of voltage-gated calcium and chloride channels, and the activation of protein kinase C, protein kinase A, phosphatidylinositol-3 kinase (PI3K) and phospholipase C ( 4 ). (jcancer.org)
Vitamin D is a hormone regulating not only calcium and phosphate homeostasis but also, at the same time, exerting many other extraskeletal functions via genomic effects (gene transcription) and probably by non-genomic effects as well. (karger.com)
