background: the study of the association between genotype and phenotype is of great importance for the prediction of many diseases and pathophysiological conditions. the relationship between angiotensin-converting enzyme (ace) gene insertion/ deletion (i/d) polymorphism and pathological processes such as coronary artery disease (cad) has been investigated previously with discordant results. thi...

the aims of the present study were to propose apolymerase chain reaction-restriction fragment length polymorphismpcr-rflp genotyping method for the ay_376689:c.773c>t single nucleotide polymorphism snp of the equine prkag3 gene, related to muscle performance, as well as to characterize this snp and a second polymorphism, aawr_02017454:g.121684t>c of the spata1 gene, related to male fertility, i...

conclusions although we found an association between myh9 gene polymorphism and urinary albumin excretion, the results did not show a significant association between myh9 polymorphism (rs4821481) and risk of dn in iranian diabetic patients. background myosin heavy chain 9 (myh9) gene polymorphisms have been implicated in different types of renal disease, as well as in nephropathy attributed to ...

background : the main function of the pineal hormone melatonin which is mediated via its two receptors, mtnr1a and mtnr1b, is to mediate dark signals in addition to anti-oxidation, immune system enhancement, protection from radiation, and anti-cancer functions. a common single nucleotide polymorphism in the mtnr1b gene is rs#10830963, which is well known as a risk factor for type 2 diabetes mel...

abstract background: schizophrenia is a severe mental disorder and numerous genes and loci are beleived to be involved in this disease. recent studies have reported a strong genetic association between dtnbp1 (dystrobrevin-binding protein 1) gene variants and schizophrenia. methods: in this research, we used a case-control study to establish the possible association between the p1635 (rs3213207...

Background:It has been hypothesized that genetic factors other than histocompatibility disparity may play a role in predisposition to developing Chronic Myelogenous Leukemia (CML). In this regard, Th1 and Th2 cytokines and their gene polymorphism seems to be important. Overall expression and secretion of cytokines is dependent, at least in part, on genetic polymorphism (nucleotide variations) w...

Introduction: Allergic Rhinitis (AR) is a common inflammatory disease of the nasal mucosa. The CD14 is a receptor for lipopolysaccharide and inhaled endotoxin which can stimulate the production of interleukins by antigen presenting cells. Accordingly, CD14 plays an important role in allergic and atopic diseases, which can be one of the etiological factors for allergic diseases. The present stud...

Background: Breast cancer is one of the most common cancers among women worldwide. Tumor protein 53 (TP53) and its regulator the mouse double murine 2 (MDM2) have important roles in tumorigenesis by playing key roles in cell division and response to DNA damage. MDM2 SNP309 T>G (rs2279744) polymorphism in the promoter region of MDM2 gene can cause dysfunction and inactivation of TP53 which promo...
