The fundamental role of vitamin D receptor (VDR) gene polymorphisms have been reviewed. The VDR gene polymorphisms are associated with the intestinal calcium absorption , rate of bone gain and loss. The observed variability in younger and elderly people in the response of bone mass to calcium intake and supplementation may be explained partly by the interaction between environmental and genetic factors.

Vitamin D affects bone metabolism and calcium-phosphate metabolism. Its deficiency leads to bone mineralization disorders and is the cause of abnormal skeletal development from fetal life to the period of completed skeletal growth. In later periods of life, vitamin D deficiency leads to bone metabolism disorders, i.

Background/objectives: Vitamin D helps the mineralization of bone, teeth, and other calcified tissues by regulating calcium-phosphate metabolism. The nuclear activation of the vitamin D receptor () gene is essential for the effectiveness of vitamin D. The main objective of this study is to determine the role of vitamin D levels and gene variants in dental caries.

Purpose: The effect of exercise on serum concentration of vitamin D metabolites remains inconclusive, with studies reporting deviating results. This study evaluated the acute effect of a single session of two specific exercise forms; strength training (ST) and high-intensity interval training (HIIT), on circulating 25-hydroxyvitamin D (25(OH)D), free25(OH)D and 1,25-dihydroxyvitamin D (1,25(OH)2D), and skeletal muscle vitamin D receptor (VDR) gene expression, in healthy adults.
Methods: Thirty-nine participants (19 women and 20 men, age 21-30 years) completed a single bout of ST and HIIT exercise, separated by two weeks.

Vitamin D deficiency is a public health problem worldwide. Some studies have associated serum vitamin D deficiency with knee osteoarthritis. Additionally, some vitamin D receptor polymorphisms have been linked to knee osteoarthritis.

Background: The vitamin D pathway contributes to the microbicidal activity of macrophages against infection. In addition to induction of this pathway, interferon-gamma (IFNγ), interleukin (IL)-15, and IL32γ are part of a network of pro-inflammatory cytokines. The aim of this study was to evaluate single-nucleotide polymorphisms (SNPs) in the components of the vitamin D pathway and associated cytokine genes that could be related to resistance or susceptibility to American tegumentary leishmaniasis (ATL).
