چکیده

Tissue barriers are critical in the pathogenesis of human diseases, such as atopic dermatitis, inflammatory bowel diseases, and various cancers. Preserving or restoring barrier functions of the epithelia cells is a therapeutic strategy to prevent and treat the illness. Mounting evidence indicates that vitamin D and the vitamin D receptor (VDR) play key roles in the pathogenesis of human diseases. In particular, we note an interesting link between vitamin D/VDR signaling and tissue barriers. In the current review, we summarize the recent progress on vitamin D and cell junction complexes. We focus on the functions of VDR and VDR-associated intracellular junction proteins, such as β-catenin and claudins. We also discuss the potential therapeutic functions of vitamin D in treating defective tissue barriers that involve skin, intestine, lung, kidney, and other organs. However, the mechanisms for the vitamin D/VDR signaling in tissue barriers remain largely unknown. Further studies on vitamin D/VDR's multiple functions in physiological models will suggest new therapeutic targets for prevention and treatment diseases with defective barrier functions.

Evaluation of relationship between BMI with vitamin D receptor gene expression and vitamin D levels of follicular fluid in overweight patients with polycystic ovary syndrome

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...

The Association of Vitamin D Receptor Gene BsmI Polymorphism with Multiple Sclerosis in Iranian Patients

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...
