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...

Introduction. Vitamin D deficiency may be an independent predictor of coronary heart disease (CHD) and the severity atherosclerosis. The results studies association various polymorphisms vitamin receptor ( VDR ) gene with risk CHD are contradictory, which necessitates study genetic variants characteristics clinical course in Russian population. objective was to determine distribution genotypes ...

Background: A number of genes are associated with the incidence non-syndromic cleft lip/palate (NSCL/P). Studies have shown a significant association between polymorphisms ATP-binding cassette, sub-family A, member 4 (ABCA4) risk NSCL/P. The present meta-analysis assessed ABCA4 (rs560426 and rs481931) NSCL/P by reviewing case-control studies. Methods: Four databases (Scopus; Cochrane Library; W...

introduction: a thyroid nodule is a palpable swelling in a thyroid gland with an otherwise normal appearance. palpable thyroid nodules occur in 4 to 7 percent of the population. nodular thyroid diseases are more frequent in women than in men. most actions of thyroid hormone are mediated by the active form of thyroid hormone. d2 is essential for formation of active hormone of t3 through deiodina...

the aim of the study was to explore the mechanisms underlying the association of birth weight with later body mass index (bmi) from the biochemical markers related to metabolism and the apa i polymorphism in igf-ii gene.a total of 300 children were selected randomly from the macrosomia birth cohort in wuxi, china. the height and weight were measured and blood samples were collected. plasma conc...

aim : the present study evaluated the association between g241r and k469e polymorphisms of intercellular adhesion molecule 1 gene and inflammatory bowel disease in iranian population.   background : inflammatory bowel disease including ulcerative colitis and crohn’s disease, is a chronic idiopathic inflammatory disease of the gastrointestinal tract. there are two single base polymorphisms of in...

henoch–schönlein purpura (hsp), a common allergic hemorrhagic disease, occurs frequently in children affecting kidney, joint and skin. while interleukin-8 (il-8) plays an important role in inflammation, the association between il-8 gene +781 c/t polymorphism and hsp remains unclear. interleukin-8, an important chemokine related to the initiation and amplification of acute inflammatory responses...

The T-786C promoter and 27-bp repeat intron 4 polymorphisms in the endothelial NO synthase (eNOS) gene have been inconsistently associated with various eNOS-related phenotypic changes. We explored molecular mechanisms underlying the inconsistency. We constructed pGL3 luciferase reporter vectors by inserting an eNOS promoter fragment containing either T or C nucleotide at -786 bp at the 5' end o...

OBJECTIVES Controversy exists regarding the effects of polymorphisms in the endothelial nitric oxide synthase (eNOS) gene on nitrites/nitrates (NOx) plasma concentrations. In this study we compared the distribution of haplotypes involving three relevant eNOS polymorphisms (T-786C in the promoter region; b/a in intron 4, and Glu298Asp in exon 7) in healthy subjects with low and high circulating ...
