Background and purpose: Cytokines are a group of endogenous proteins which play an influential role in regulating the inflammatory responses and defeating infectious diseases. Elevated levels of proinflammatory cytokines and their receptors are usually observed in association with immune responses against viral infections such as hepatitis B virus (HBV) infection. IL 12 and its receptor play an...

Background: Indirect genetic diagnosis using polymorphic DNA markers can detect carriers of hemophilia A. This technique is preferable in developing countries because of its simplicity and cost effectiveness compared to direct mutation analysis. In the present study, we examined usefulness of intragenic marker BclI restriction fragment length polymorphism (RFLP) at intron 18, for carrier detect...

Introduction: Vitamin D fulfills its crucial role in cell proliferation and death through signal transduction into the nucleus by vitamin D receptor (VDR). Recent studies have depicted the association between VDR gene polymorphisms and different cancers, including breast cancer. This study attempted to consider the relationship between VDR gene polymorphisms and breast cancer risk among women i...

BackgroundAttention deficit hyperactivity disorder (ADHD), is a multifactorial disorder and converging evidence has implicated abnormalities of dopamine neurotransmission. The aim of this study was to examine the association of -141 polymorphisms in DRD2 gene with ADHA among Iranian-Azeri population.Materials and Methods A case–control association study included 153 patients with attention defi...

Introduction: Studies show polymorphism in leptin gene cause increase in level of leptin hormone and increased level of leptin hormon is associated with abosity, insulin resistance and increased risk of colorectal cancer. The aim of this study was to assess the incidence of leptin gene polymorphism rs 7799039 in Tehran and to investigate the influence of this polymorphism in increased risk of c...

Background and purpose: Chronic lymphocytic leukemia (CLL) is the most common form of adult leukemia characterized by the accumulation of seemingly mature type B lymphocytes in peripheral blood and lymphatic organs. One of the main markers used in the diagnosis and prognosis of CLL is the CD38 gene. Polymorphism is considered to be a major genetic source of phenotypic change within a species an...

Background: The p53 tumor suppressor gene plays important roles in genomic stability. Several reports have noted racial differences in the prevalence of p53 genotypes at the codon 72 in patients with endometriosis.To study the association of endometriosis with p53 codon 72 polymorphism in the population of Isfahan. Materials and Methods: We undertook a case–control study to examine the possible...

results the frequencies of the aa, at, and tt genotypes were 31%, 51%, and 18% in the chronic hbv patient group, and 40%, 45%, and 15% in the healthy control group, respectively. however, a lack of association of the + 874 polymorphism in the ifn-γ gene of those with chronic hbv infection was found. evaluation of hbv association with this polymorphism was significant under the dominant genetic ...
