Roles (5)

RoleDescription
bone density conservation agentAn agent that inhibits bone resorption and/or favor bone mineralization and bone regeneration. Used to heal bone fractures and to treat bone diseases such as osteopenia and osteoporosis.
nutraceuticalA product in capsule, tablet or liquid form that provide essential nutrients, such as a vitamin, an essential mineral, a protein, an herb, or similar nutritional substance.
metaboliteAny intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
human metaboliteAny mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
mouse metaboliteAny mammalian metabolite produced during a metabolic reaction in a mouse (Mus musculus).

Drug Classes (3)

ClassDescription
hydroxycalciol
D3 vitaminsA vitamin D that is calciol or its hydroxylated metabolites calcidiol and calcitriol. Calciol (also known as vitamin D3) acts as a hormone precursor, being hydroxylated in the liver to calcidiol (25-hydroxyvitamin D3), which is then further hydroxylated in the kidney to give calcitriol (1,25-dihydroxyvitamin D3), the active hormone.
diolA compound that contains two hydroxy groups, generally assumed to be, but not necessarily, alcoholic. Aliphatic diols are also called glycols.

Plasma PTH Level

Building upon our hypothesis above, this aim exploits the fact that the nuclear Vit-D Receptor (VDR) regulates parathyroid hormone (PTH) gene transcription. Therefore the plasma PTH level serves as a sensitive biomarker of the Vit-D nutri-genomic response. This aim will define the multivariate determinants (covariates such as age, BMI, baseline Vit-D level and dietary calcium) of the Vit-D-PTH level relationship (the primary outcome variable) in African-Americans. It is anticipated that the Vit-D supplementation trial will document a wide variance of Vit-D-PTH level relationships that will identify patients at the upper and lower quartiles of the distribution that are either 'nutrient-responsive' or 'nutrient-resistant'. These studies should help identify the 'clinical' characteristics of the sub-set of African-Americans that exhibit the poorest response to Vit-D supplementation. (NCT02802449)
