Glucose-regulated protein 78 (GRP78), an endoplasmic reticulum chaperone, up-regulation serves as an efficient mechanism to promote malignant transformation of colorectal cancer (CRC) and protect CRC cells against apoptosis. Recently, the analysis of GRP78 polymorphisms has already determined that GRP78 rs391957 polymorphism could predict clinical outcome in CRC patients. Thus, we tested whethe...

Our study aimed to investigate the correlation between single nucleotide polymorphisms of ERCC1/XRCC1/XPA genes and postoperative chemotherapy efficacy and prognosis of endometrial carcinoma. Our study included 108 patients with endometrial carcinoma and 100 healthy participants. ERCC1 rs11615/XRCC1 rs25487/XPA rs1800975 gene polymorphisms were detected by polymerase chain reaction-restriction ...

BACKGROUND/AIMS It has been confirmed that telomere length (TL) correlates with chronological donor age and that telomere shortening is accelerated in allografts. The aim of this study was to analyse the associations between graft rs2735940 hTERT and rs2630578 BICD1 gene polymorphisms and rs7235755/rs2162440 chromosome 18 polymorphisms, relative TL and kidney function after transplantation. M...

AIM To investigate the association of tumor necrosis factor alpha (TNFα) -G308A polymorphism with different liver pathological changes in treatment-naïve Egyptian patients infected with hepatitis C virus (HCV) genotype 4. METHODS This study included 180 subjects, composed of 120 treatment-naïve chronic HCV patients with different fibrosis grades (F0-F4) and 60 healthy controls. The TNFα -G308...

Toll-like receptors 4, 5 and 9 (TLR4, 5 and 9) are involved in the induction of innate immune response against hepatitis B virus (HBV) infection. This study aimed to explore the potential role of TLR4, 5 and 9 polymorphisms in the susceptibility to HBV clearance and HBV-related hepatocellular carcinoma (HCC). In this study, five single nucleotide polymorphisms (SNPs) (rs1927911, rs11536889, rs1...

This aim of the study was to investigate the effect of CYP1A2 gene polymorphism on the metabolism of theophylline in minority and Han nationality. A total of 50 cases of Han (Han group) and 50 minority nationalities (ethnic groups) treated with theophylline were selected for the study. The genotype and allele frequencies of the two groups of CYP1A2 gene, G-3113A and G-3860A, were compared to de...

Several studies suggest an important role of Acyl-CoA: cholesterol acyltransferase-1(ACAT-1) in the development of atherosclerosis. The aim of present study was to investigate whether there exists a possible correlation between genetic variations in ACAT-1 genes and coronary artery disease (CAD) risk. Four polymorphisms (rs1044925, rs11545566, rs12121758 and rs10913733) were finally selected an...

BACKGROUND The phosphoinositide 3-kinase (PI3K)/protein kinase B (PKB, AKT)/mammalian target of rapamycin (mTOR) signaling pathway plays a critical role in angiogenesis and cell growth, proliferation, metabolism, migration, differentiation, and apoptosis. Genetic diversity in key factors of this pathway may influence protein function and signal transduction, contributing to disease initiation a...

We conducted a case-control study to evaluate the association between ERCC5 polymorphism and breast cancer risk. 325 breast cancer patients and 325 controls were recruited in our study between January 2011 and March 2014. ERCC5 rs1047768, rs2094258, rs2296147, rs751402 and rs873601 polymorphisms were genotyped, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) ...

Expression of estrogen receptors is correlated with breast cancer risk, but inconsistent results have been reported. To clarify potential estrogen receptor (ESR)-related breast cancer risk, we analyzed genetic variants of ESR1 in association with breast cancer susceptibility. We performed a meta-analysis to investigate the association between rs2234693, rs1801132, and rs2046210 (single nucleoti...
