There are many immune mediated disorders with the corroborated role of vitamin D or Vitamin D Receptor (VDR) gene polymorphisms in their pathogenesis, immunologic regulation, and disease characteristics. Therefore, in this review, we searched PubMed data base in regard to the role of VDR gene polymorphisms in common autoimmune disorders, emphasizing on dermatologic diseases.

Background & Aims: 1,25-dihydroxyvitamin D3 (1,25 (OH)2 D3), the biologically active form of vitamin D, exerts an immunosuppressive effect through binding to its specific nuclear receptor. The present case-control study was done to examine the possible association of BsmI polymorphism in vitamin D receptor gene (VDR gene) with severity of multiple sclerosis (MS). Methods: 267 Iranian patients w...

background: vitamin d plays a critical role in the regulation of growth and differentiation of squamous epithelium. the pleiotropic effects of 1,25-dihydroxyvitamin d3 [1,25(oh)2d3], include proliferative, pro-apoptotic, and pro-differentiation effects on numerous cell types. although 1,25-dihydroxyvitamin d3 is involved in the regulation and differentiation of epithelium, there is no data in t...

background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocal­cin and cross laps. the fok i polymorphism in ...

Objective(s) Deregulation of the immune system through allied factors and cytokine responses are thought to be important contributors to the pathogenesis of asthma. Vitamin D3 and its nuclear receptor appear to be factors that maybe involved in regulating immune responses during the progression of asthma. The aim of this study was to investigate the association between polymorphisms in intron ...

Background & Aims: Many studies have demonstrated that Vitamin D has an important role in cell growth and proliferation and vitamin D receptor polymorphism has significant relationship with colorectal cancer (CRC). The aim of this study was to assess the incidence of VDR rs 2238136 polymorphism in Iranian population and to investigate the relationship between this single nucleotide polymorphism...

background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...

multiple sclerosis (ms) is a multifactorial disease (caused by both environmental and genetic features) that could results from a demyelination of the myelin sheath. subsequently, it leads to many scars or lesions in different places within the central nervous system. the symptoms that occur depend on the site and rigorousness of the lesions and this is why people with ms experience different s...

objective(s) deregulation of the immune system through allied factors and cytokine responses are thought to be important contributors to the pathogenesis of asthma. vitamin d3 and its nuclear receptor appear to be factors that maybe involved in regulating immune responses during the progression of asthma. the aim of this study was to investigate the association between polymorphisms in intron 8...

Background Polycystic ovary syndrome (PCOS) is the most common endocrine disorder. The roles of vitamin D in the regulation of metabolic modulations specifically involving insulin action and reproduction processing are introduced. In addition, obesity appears to be closely associated with severity of PCOS. The aim of this study was to evaluate the effect of BMI on vitamin D levels in follicular...
