Genetic polymorphism G6721T (rs.7003908) in gene encoding DNA-dependent protein kinase (DNA-PKcs, encoded by the XRCC7 gene) has been defined. In order to get more insight into the genetic structure of Iranian population the present study was carried out on Iranian Persian population living in Shiraz (Fars province, southwest Iran). The total study subjects consisted of 935 (195 males, 740 fema...

X chromosome inactivation is widely studied using DNA sequence polymorphisms and DNA methylation as a surrogate measure of inactivation, but the correlation of methylation with inactivation is not perfect. Thus, it may be better to study sequence polymorphisms expressed in the mRNA. A recent paper reported use of a silent C/T polymorphism at nt 1311 of the G6PD cDNA, and this polymorphism was r...

BACKGROUND Evidences are suggesting that DNA damage is implicated in development of systemic lupus erythematosus (SLE). Therefore we focused on two common XRCC1 polymorphisms (Arg399Gln and Arg194Trp) in SLE susceptibility in South East of Iran. METHODS Peripheral blood DNA was extracted from 163 SLE patients and 180 healthy controls. PCR-restriction fragment length polymorphism method was us...

background : gastric cancer as the fourth most frequent malignancy worldwide was known to have the highest rate among cancer-related disorders in ardabil province. the product of tp53 gene regulated  the cell cycle process and acts as a tumor suppressor factor. the polymorphism p53 arg72pro (rs1042522) has been reported to be associated with many type of cancers.  the purpose of the present stu...

background: leishmaniasis is important vector-borne parasitic disease worldwide, caused by the genus leishmania . the objective of the current study was to identify genetic polymorphism in l. major , one of the species causing cutaneous leishmaniasis (cl), isolated from southeastern iran, using permissively primed intergenic polymorphic-polymerase chain reaction (ppip-pcr) method. methods: over...

objective: jaundice with indirect hyperbilirubinemia is one of the most common neonatal problems that occur in 60% of term and 80% of preterm neonates but the causes are mostly unknown. it is suggested that race plays an important role in the prevalence of hyperbilirubinemia. it is a common problem in iran that worries both parents and pediatricians. it has been found that a mutation in the ugt...

background: obesity is a global public health problem. visfatin, as an adipocytokine, is coded by a gene known as nicotinamide phosphoribosyltransferase. so far, results were conflicted  regarding correlations of visfatin with obesity and metabolic variables.the present study aimed to explore the association between g?948t polymorphism of visfatin gene with obesity and lipid profile in a nation...

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...

BACKGROUND Based on differences in individual immune responses to the hepatitis B virus (HBV), between 5% and 10% of patients become persistently infected with the virus, which leads to the determination of chronic HBV. Cytokines such as interferon gamma (IFN-γ) are secretory proteins that play important roles in both innate and adaptive immune responses. Functional studies have demonstrated th...
