Background: Subclinical hypothyroidism (SCH) remains largely unnoticed as a major cause of infertility due toasymptomatic. Polymorphisms of phosphodiesterase 8B gene (PDE8B) have been linked with various diseases,including female infertility. Hence, we aimed to study prevalence of SCH, in infertile females, explore associationof PDE8B rs4704397 A/G and rs6885099 G/A polymorphi...
Diabetic dyslipidemia is one of the leading causes of coronary artery disease (CAD) death. Genetic and environmental factors play an important role in the development of type 2 diabetes mellitus (T2DM) and dyslipidemia. The present study was aimed to investigate the association of ACE (rs4646994), FABP2 (rs1799883), MTHFR (rs1801133) and FTO (rs9939609) genetic polymorphism in T2DM with dyslipi...
Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system with presumed autoimmune origin. T cells are considered to play a pivotal role in orchestrating the self-reactive immune responses in multiple sclerosis (MS). This study was performed to investigate the role of polymorphisms of the programmed cell death 1 (PD-1) gene on susceptibili...
Investigating Genetic Diversity and Relationships in some Henbane (Hyoscyamus spp.) Populations Based on Polymorphisms Resulting from Retrotransposon Insertion
Glutathione S-transferases (GSTs; EC: 2.5.1.18) are ubiquitous multifunctional enzymes, which play a key role in cellular detoxification. Functional genetic polymorphisms in genes encoding GSTM1 (a member of GST class mu; OMIM: 138350), and GSTT1 (a member of GST class theta; OMIM: 600436) have been well defined. The functional null alleles of GSTM1 and GSTT1 represent deletions of GSTM1 and GS...

abstract background: gastric cancer is one of the most common malignant tumors in iran. hypomethylation and/or hypermethylation of dna have been described in gastric cancer and is presumed to be an early event in this process. objective: we hypothesized that single nucleotide polymorphisms of dnmt1 gene may be associated with the genetic susceptibility to gastric cancer. methods: 200 patients a...
Abstract Background: Sporadic colorectal cancer is the fourth most common cancer in Iran. The DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT) is involved in the cellular defense against alkylating agents. Genetic alterations in the MGMT gene may impair the protein’s ability to remove alkyl groups from the O6-position of guanine, thereby raising the mutation rate and increasi...
asthma as a chronic inflammatory airway disease is considered to be the most common chronic disease that is involving genetic and environmental factors. toll like receptors (tlrs) and other inflammatory mediators are important in modulation of inflammation. in this study, we evaluated the role of tlr2 arg753gln and tlr4 asp299gly polymorphisms in the asthma susceptibility, progress, control lev...
Abstract There was a difference in the genetic profiles of CYP21 genotype, it showed three polymorphisms: 250/240, 260/251 and 270/261 bp, their distribution ratios were 51.72, 29.31, 18.96%, respectively. The percentages highly significant differences (P≤0.01), total studied alleles 116. study that there no production milk its components between polymorphisms, as well rate flow. (P≤0.05) diffe...
