Background: Lots of vitamin D functions are mediated by its steroid family receptor (VDR). Vitamin D role in infertility is reported by significant fertility reduction in many male laboratory animals with vitamin D deficiency. The reason for reduced fertility in male VDR-null mouse model has been reported to be reduced sperm count and sperm motility. Vitamin D has effects on sperm motility, spe...
Background & Aims: Scleroderma is a chronic connective tissue disease with unknown etiology. Vitamin D, a necessary hormone that plays a particular function in the calcium and phosphate homeostasis, is involved in etiology of this disorder. Klotho, co-receptor of fibroblast growth factor 23 (FGF-23), can interfere in calcium and phosphate metabolism. The purpose of this study was to determ...
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...
Objective(s): Cyclic AMP (adenosine monophosphate) response element-binding protein (CREB) and Brain-derived neurotrophic factor (BDNF) are reported to broadly involve in learning capacity and memory. BDNF exerts its functions via tropomyosin receptor kinase B (TrkB). BDNF transcription is regulated by stimulating CREB phosphorylation. The CREB-TrkB-BDNF pathway is rep...
INTRODUCTION Vitamin D deficiency and vitamin D receptor (VDR) gene polymorphism, FokI, is reported to increase the risk of many cancers. Role of vitamin D and its receptor polymorphisms in ovarian cancer has not been clearly defined. OBJECTIVE To study the levels of serum vitamin D and occurrence of vitamin D receptor gene polymorphism (FokI) in cases of ovarian cancer. MATERIAL AND METHOD...
Background and Aim: In addition to exposure to Mycobacterium tuberculosis (MTB), development of tuberculosis is influenced by environmental and host genetic factors, and clinical disease only occurs in less than 10% of the infected individuals. Vitamin D metabolism leads to activation of macrophages and restricts the intracellular growth of mycobacterium. This effect may be influenced by poly...
Deficiency of vitamin D3 has become common in both developed and developing countries. Vitamin D receptors are found on the granulosa cells ovarian tissue its deficiency plays a role dysfunction. Anti Mullerian Hormone (AMH) is generated small growing follicles ovaries by cells. Serum AMH one marker for reserve. We reviewed current literature present clinical practice. There relationship betwee...
Background & Aims: Tuberculosis is the second factor in the deaths caused by infectious diseases in the world. Out of every ten infected people, only in one the clinical symptoms of the disease is developed. The correct vitamin D receptor activity on the nuclei of macrophages is one of the main components of the host innate immunity against M. tuberculosis. In the present study, the relation...
Objective: The role of vitamin D has soared to a pinnacle in recent years with functions affecting 229 human genes linked to cardiovascular, autoimmune, humoral, pulmonary and neurological diseases. Relationship between obesity and vitamin D has not as yet been fully established. The objective of the study was to determine the possible relationship between Vitamin D receptor (VDR) gene polymorp...
