conclusions the present clinical study suggests that the transmission of an hbv genotype other than genotype d, namely hbv genotype g, is possible in turkey. epidemiological and clinical information on genotype g infection is currently limited, and this is most likely due to its low prevalence throughout the world. therefore, it may be important to determine the epidemiologic and molecular char...
Background & Aims: Behcet’s disease (BD) is an inflammatory vasculitis of unclear etiology. MCP-1 gene is a member of the C-C chemokines family that is a chemotactic factor for monocytes. The results obtained have shown that the -2518A/G polymorphism of MCP-1 gene is associated with BD. The aim of this study was to evaluate the possible involvement of this polymorphism and Behcet&rsq...
Introduction: Breast cancer is the most common malignancy worldwide, which affects women. Also, this disease is one of the most frequent malignancies among women in Iran. Apoptosis is a known mechanism against cancer, which has intrinsic and extrinsic pathways. One of these extrinsic pathways, is Fas receptor-ligand system, which plays a key role in apoptotic signaling in many cell types, parti...
Background: Helicobacter pylori vacA (vacuolating toxin A) gene is comprised of mid- (m), intermediate- (i) and signal-regions. Recently, the vacA-i region genotype has been suggested to be a better predictor of disease severity than either the s- or m-region. The main aim of the present study was to determine the associations of i region poly-morphisms of vacA gene with gastric cancer (GC) and...
Objective(s): Accumulating evidence has demonstrated that miRNAs contribute to various genetic and epigenetic modifications in the pathogenesis of gastric cancer (GC). Recent studies focused on the four single nucleotide polymorphisms (SNPs) of pre-miRNAs including rs11614913, rs3746444, rs2910164, and rs2292832. It was suggested that these four SNPs were significantly associated with the risk ...
The genetic polymorphism of some genes related to meat production in three Egyptian sheep breeds (Barki, Rahmani and Osseimi) was studied. The candidate genes were: Calpastatin, Myostatin, Diacylglycerol-acyltransferase1, Insulin-like growth factor binding protein-3 and Booroola fecundity gene. The technique applied was the restriction fragment length polymorphism for the polymerase chain react...
بررسی شیوع پلیمورفیسم rs 1049174 ژن NKG2D در بیماران مبتلا به سرطان پستان و مقایسه آن با افراد سالم
Introduction: NKG2D receptor is one of the activator receptors of immune cells. In humans, NKG2D gene has two single nucleotide polymorphisms (SNP)(rs1049174G>C). According to other studies, GG SNP makes a high affinity receptor for NKG2D ligands whereas, CC polymorphism reduces NKG2D affinity for their ligands. The present study investigates NKG2D SNPs in patients with breast cancer in Yazd f...
Several previous studies indicated that genetic polymorphisms in inflammatory factor genes were associated with glioma risk. However, the relationship between the prostaglandin-endoperoxide synthase 2 (PTGS2) genetic polymorphism and glioma remains unclear in the Chinese population. We selected 199 histologically confirmed adult glioma patients and 199 cancer-free controls for the present study...
Background and purpose: The standard of care treatment for infected patients with HCV is based on a combination of pegylated interferon alpha and ribavirin. Recently, the rs12979860 SNP polymorphism, located upstream of the interleukin 28B gene, was shown to be strongly associated with response to anti-HCV therapy. This study investigated the distribution of the (C/T) polymorphism with sust...
Gastric cancer is the fourth most common cause of malignancy death in the world, which also has a high prevalence in Iran. Caspase 3 gene is considered one of the major genes related to gastric cancer. The present study aimed to investigate the relationship between rs12108497 polymorphism of Caspase 3 gene. Due to the fundamental role of caspases, we have considered an SNP of Caspase 3 (common ...
