backgrounds and aims: p53 gene is regarded important in pathogenesis of different cancers. therefore, this study aimed to investigate the frequency of p53 gene codon 72 arg/pro polymorphism in women suffering from breast cancer. materials and methods: a total of 90 patients with breast cancer and 83 matched healthy control women participated in this case-control study. genomic dna was extracted...

Background & Aims: Lipoprotein lipase (LPL) is one of the key enzymes regulating the metabolism of triglycerides (TG) and HDL cholesterol. The lipoprotein lipase (LPL) gene polymorphisms are possibly involved in the pathophysiology of dyslipidemia. Hind III polymorphism is one of the most common polymorphisms in LPL gene. In some studies, association of Hind III polymorphism with dyslipidemia h...

objective: in peripheral blood polymorphonuclear and mononuclear cells nitric oxide (no) could be synthesized by an enzyme called inducible no synthase (inos). inos gene (nos2a) is located on chromosome 17 at position 17q11.2-q12. no is released during inflammatory responses. in the present studies the frequency of nos2a gene polymorphisms and their effects on no production were investigated in...

background: one of the limitations in the treatment of common diseases such as cancer chemotherapy is development of multidrug re sistance (mdr). polymorphisms could alter the expression level of mdr1 gene, which plays an important role in mdr. in this research, the frequency of c3435t, c1236t, and g2677t/a polymorphisms of mdr1 gene was investigated in a large group of population from hamadan ...

objective(s):the aim of the study was to investigate the relationship between insulin resistance (ir) and leptin (lep) gene polymorphisms in peritoneal dialysis (pd) patients. materials and methods: from july 1, 2011 to august 1, 2011, patients who received chronic pd were chosen and divided into three groups (dm, high homr-ir, and low homr-ir). two pcr products of lep were sequenced and aligne...

aim :  to evaluate the association of dnmt1 and mgmt amino acid substitution polymorphisms and colorectal cancer in iranian population. background : the mgmt and dnmt1 are two important methyltransferase enzymes. amino acid substitution polymorphisms in mgmt and dnmt1 genes may be associated with the genetic susceptibility to sporadic colorectal cancer. patients and methods : we assessed eight ...

Materials and Methods: From July 1, 2011 to August 1, 2011, patients who received chronic PD were chosen and divided into three groups (DM, high HOMR-IR, and low HOMR-IR). Two PCR products of LEP were sequenced and aligne...

the purpose of the study was to detect the alui and ddei polymorphisms within pou1f1 gene exon 6 and 3'utr region in turkish sheep breeds, and their association with milk productive traits. jugular blood samples were collected from 50 sakiz, 50 white karaman, and 50 awassi sheep using edta as an anticoagulant. pcr-rflp and sequencing analysis were performed to investigate possible polymorphisms...

background: the association between interleukin‑6 (il‑6) (‑174g/c) gene polymorphisms and level of tissue breakdown and periodontal disease progression is unknown. the present study investigated quantitative parameters of interdental papilla in chronic periodontitis (cp) patients with il‑6 (‑174g/c) gene polymorphisms. materials and methods: sixty gingival samples were studied. after determinat...
