Abstract
AIMS Esophageal squamous cell carcinoma (ESCC) is characterized by high prevalence and mortality worldwide, and it is very highly prevalent in China. ESCC is caused by various factors, including microRNAs (miRNAs) whose expression have been shown to play a major role in tumor generation. Single nucleotide polymorphisms (SNPs) in miRNAs could affect susceptibility to numerous cancers. This study aimed to evaluate the relationship between SNPs in miR-124 and ESCC risk in the Chinese Kazakh population. METHODS A total of 239 Chinese Kazakh patients with ESCC and 227 healthy Chinese Kazakh individuals were recruited in this study. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was used to analyze the miR-124 rs531564 genotype. RESULTS Allele G of the miR-124 rs531564 polymorphism significantly reduced the risk of ESCC in the Chinese Kazakh population [odds ratio (OR) = 0.711; 95% confidence interval (CI): 0.508-0.996; p = 0.047]. The dominant model indicated that the CG+GG genotypes were associated with significantly decreased ESCC risk compared to the CC genotype (adjusted OR = 0.586; 95% CI: 0.396-0.867; p = 0.007). Stratification analyses showed that compared with the CC genotype, the CG and CG+GG genotypes manifested reduced ESCC risks in the female group [CG vs. CC: OR = 0.472; 95% CI: 0.255-0.872; p = 0.016; (CG+GG) vs. CC: OR = 0.472; 95% CI: 0.255-0.872; p = 0.016] and the age group of <57 years old [CG vs. CC: OR = 0.456; 95% CI: 0.258-0.806; p = 0.006; (CG+GG) vs. CC: OR = 0.456; 95%CI: 0.258-0.806; p = 0.006]. The miR-124 rs531564 polymorphism showed no significant association with histological stage, lymph node metastasis, depth of invasion, or tumor/node/metastasis stage. CONCLUSIONS Our findings are the first to be reported that the miR-124 rs531564 polymorphism decreased ESCC risk in the Chinese Kazakh population.

Abstract
This study was aimed to screen human papillomavirus (HPV) types associated with esophageal squamous cell carcinoma of Kazakh in Xinjiang using the gene chip technique and study the clinical significance of this application. The DNAs were collected from esophageal squamous cell carcinoma tissues and healthy esophageal mucosa of Kazakh adults in Xinjiang, and amplified firstly using HPV MY09/11 and then using HPV G5+/6+ to screen positive HPV specimens. These positive specimens were further detected by the gene chip technique to screen highly pathogenic HPV types. After determination with nested PCR amplification with HPV MY09/11 and G5+/6+, the infection rate of HPV was 66.67% in the esophageal squamous cell carcinoma group and 12.12% in the healthy control group. By testing the positive HPV specimens from the esophageal squamous cell carcinoma group, the infection rate of HPV16 was 97.72% and the co-infection rate of HPV16 and HPV18 was 2.27%. HPV16 infection may be involved in the development of esophageal squamous cell carcinoma in Xinjiang Hazakh adults.

Abstract
Aging associates with a variety of pathological conditions such as cancer, cardiovascular, neurodegenerative, autoimmune diseases, and metabolic disorders. The oncogenic alterations overlap frequently with the genes linked to aging. Here, we show that several aging related genes may serve as the genetic risk factors for cervical and esophagus cancers. In our study, we analyzed samples obtained from 115 patients with esophageal and 207 patients with cervical cancer. The control groups were selected to match the ethnicity and age of cancer patients. We examined the genes involved in the processes of xenobiotics detoxification (GSTM1 and GSTT1), DNA repair (XRCC1 and XRCC3), and cell cycle regulation and apoptosis (CCND1 and TP53). Our study revealed that deletions of GSTT1 and GSTM1 genes or the distinct point mutations of XRCC1 gene are associated with cervical and esophageal cancers. These results will lead to development of screening for detection of individuals susceptible to esophageal and cervical cancers. Introduction of the screening programs will allow the early and effective preventive measures that will reduce cancer incidence and mortality in Kazakhstan.

Abstract
Glutathione S-transferases (GSTs) play important roles in the detoxification of electrophilic carcinogens, and GSTM1 null genotype is associated with the dysfunction of GSTs. Previous studies investigating the association between GSTM1 null genotype and risk of esophageal carcinoma in Chinese provided inconsistent findings. To provide a more precise estimation on the association between GSTM1 null genotype and risk of esophageal carcinoma in Chinese population, a meta-analysis was performed. Eligible studies were searched in PubMed, Embase, and China National Knowledge Infrastructure databases. Odds ratio (OR) with the corresponding 95 % confidence interval (95 %CI) was used to assess the association. A total of 18 case-control studies involving 1,947 cases and 3,506 controls were finally included in the meta-analysis. Meta-analysis of those 18 studies showed that GSTM1 null genotype was associated with an increased risk of esophageal carcinoma in Chinese (random effect model OR = 1.49, 95 %CI = 1.11-2.00, P = 0.008). The findings from cumulative meta-analysis showed that the association was more obvious as the data increased by publication year. There was no risk of publication bias in the meta-analysis. Therefore, the findings from our meta-analysis provide a strong evidence for the association between GSTM1 null genotype and risk of esophageal carcinoma in Chinese population, and GSTM1 null genotype contributes to increased risk of esophageal carcinoma in Chinese.

Abstract
Genetic polymorphisms in genes encoding glutathione S-transferase T1 (GSTT1, a member of class theta) and M1 (GSTM1, a member of class mu) have been defined. Previous studies have revealed that there was significant difference between populations for allelic frequency of several members of GSTs. In order to find the prevalence of null genotypes of GSTM1 and GSTT1 in Afghanis populations the present study was carried out. The total study subjects consisted of 656 unrelated healthy Afghanis refugees living in Fars province (southern Iran). From these 257, 217, 120, and 62 individuals were Pashtuns, Tajiks, Hazaras, and Uzbeks, respectively. Genetic polymorphisms for GSTT1 and GSTM1 were detected by multiplex PCR. The prevalence of null genotype of GSTM1 in Pashtuns, Tajiks, Hazaras, and Uzbeks was 42.4, 48.4, 52.5, and 40.3 %, respectively. There was no significant difference between these populations for the genotypic distribution of the GSTM1 polymorphism (χ(2) = 4.67, df = 3, P = 0.197). The frequency of GSTT1 null genotype in Pashtuns, Tajiks, Hazaras, and Uzbeks was 7.4, 25.3, 25.0, and 29.0 %, respectively. The observed difference between populations for prevalence of GSTT1 null genotype was statistically significant (χ(2) = 35.54, df = 3, P < 0.001). In comparison with European and Asian populations, Afghanistan populations like Iranian populations showed intermediate frequency for GSTT1 and GSTM1 null genotypes.

Abstract
Glutathione S-transferases (GST) belong to a superfamily of phase II enzymes believed to be associated with enhanced frequency of esophageal carcinoma. This study was performed to evaluate whether the GST family was associated with susceptibility to esophageal carcinoma in China. Ninety-seven patients with newly diagnosed, untreated esophageal squamous-cell carcinoma (ESCC) and 97 healthy controls matched in age, gender, and residence were recruited in this community-based case-control study. Null genotypes of GSTM1 and GSTT1 were determined by multiplex polymerase chain reaction (PCR) technique. Ile105Val polymorphism in the fifth exon, mRNA level, CpG island hypermethylation of promoter, and protein levels of GSTP1 gene were measured with peripheral blood mononuclear cell (PBMC) by PCR-restriction fragment length polymorphism (PCR-RFLP) techniques, quantitative real-time reverse transcription PCR, methylation-specific PCR (MSP), and Western blotting, respectively. The results showed that GSTM1 null genotype and GSTT1 null genotype were significantly associated with increased risk for esophageal cancer in Chinese population. Compared with the control, the relative expression levels of mRNA were significantly reduced in ESCC patients. The conditional logistic regression analysis demonstrated that increased risk for esophageal cancer was associated with CpG island hypermethylation of promoter of GSTP1 gene. GSTP1 protein levels also showed significant decrease in ESCC when adjusted for age, gender, smoking status, and alcohol use. An individual with GSTM1 or GSTT1 null genotype may thus be more susceptible to esophageal cancer development. Reduced expression in mRNA and protein levels were the main manifestations noted in aberrant function of GSTP1 gene. Data thus suggest that the CpG island hypermethylation of promoter gene may serve as a useful biomarker for early diagnosis of esophageal carcinoma development.

Abstract
Glutathione S-transferase (GST) enzymes are known to metabolize tobacco-related carcinogens. Previous studies on the association of functional polymorphisms of GST genes with esophageal squamous cell carcinoma have yielded conflicting but overall null results. A few studies of esophageal adenocarcinoma were likewise conflicting, but the scarcity of data is striking. We aimed to study associations of the GSTM1 and GSTT1 null deletion polymorphisms as well as the GSTP1 Ile105Val polymorphism with risks for esophageal and gastric cardia cancers. DNA was prepared from 96 and 79 cases of esophageal adenocarcinoma and squamous cell carcinoma, respectively, 126 cardia cancer cases, and 471 population-based controls. Pyrosequencing typed the GSTP1 Ile105Val polymorphism, while multiplex PCR detected GSTM1 and GSTT1 deletions. Logistic regression modeling estimated odds ratios (ORs) with 95% confidence intervals (CIs). None of the studied polymorphisms were related to the risk of esophageal adenocarcinoma, but the variant GSTP1 Val(105) allele was associated with an increased risk of esophageal squamous cell carcinoma (OR = 1.7; 95% CI 1.0-2.9) and tended to be weakly, positively linked to cardia cancer (OR = 1.4; 95% CI 0.9-2.1). Finally, we performed a meta-analysis and found that GSTP1 polymorphism seems to be associated with the risk of esophageal squamous cell carcinoma among Caucasian population (OR = 1.4; 95% CI 1.0-2.2; p value for heterogeneity test 0.34).
