N-acetyltransferase 2 polymorphisms and risk of esophageal cancer in a Chinese population.

ABSTRACT: Esophageal cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death in China in 2009. Genetic factors might play an important role in the carcinogenesis of esophageal squamous cell carcinoma (ESCC). We conducted a hospital-based case-control study to evaluate ten NAT2 tagging single nucleotide polymorphisms (SNPs) on the risk of ESCC. Six hundred and twenty-nine ESCC cases and 686 controls were recruited. Their genotypes were determined using the ligation detection reaction method. In the single locus analyses, there was a borderline statistically significant difference in genotype frequencies of NAT2 rs1565684 T>C SNP between the cases and the controls (p?=?0.057). The NAT2 rs1565684 CC genotype was associated with a borderline significantly increased risk for ESCC (CC vs. TT: adjusted OR?=?1.77, 95% CI?=?0.97-3.21, p?=?0.063 and CC vs. TT/TC: adjusted OR?=?1.68, 95% CI?=?0.93-3.04, p?=?0.085). The association was evident among older patients and patients who never drunk. After the Bonferroni correction, in all comparison models, NAT2 rs1565684 T>C SNP was not associated with ESCC risk (p>0.05). For the other nine NAT2 SNPs, after Bonferroni correction, in all comparison models, the nine SNPs were also not associated with ESCC risk (p>0.05). Thus, nine NAT2 tagging SNPs were not associated with risk of ESCC. NAT2 rs1565684 T>C SNP might play a slight role in ESCC etiology. Additional, larger studies and tissue-specific biological characterization are required to confirm the current findings.

Project description:Objective:The main aim of this study was to investigate the association of polymorphisms in long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) with the risk of esophageal squamous cell carcinoma (ESCC) in a Chinese population. Methods:A total of 245 ESCC patients and 490 gender- and age-matched cancer-free controls were genotyped for four tag single nucleotide polymorphisms (SNPs) of MALAT1 (rs3200401 C > T, rs1122709 C > G, rs664589 C > G, and rs619586 A > G). Statistical analyses including chi-squared test and logistic regression were performed to identify the association between the tag SNPs and risk of ESCC, and false discovery rate (FDR) <25% was applied to adjust for multiple comparisons. Results:We found that rs3200401 C > T polymorphism of MALAT1 was significantly associated with increased risk of ESCC (CT vs CC: adjusted OR =1.59, 95% CI =1.07-2.35, P=0.021; TT vs CC: adjusted OR =2.27, 95% CI =1.04-4.96, P=0.039; dominant model [CT+TT vs CC]: adjusted OR =1.68, 95% CI =1.16-2.43, P=0.006). In the stratified analysis, rs3200401 TT and CT/TT genotypes were associated with increased risk of ESCC compared with CC genotype in subgroup of never drinking (TT vs CC: adjusted OR =2.34, 95% CI =1.02-5.34, P=0.044; CT/TT vs CC: adjusted OR =1.52, 95% CI =1.02-2.26, P=0.041). However, compared with AA genotype, MALAT1 rs619586 GG was associated with decreased risk of ESCC in ever drinking subgroup (GG vs AA: adjusted OR =0.38, 95% CI =0.15-0.99, P=0.049). The results remained significant after FDR adjustment (FDR value <0.25) except for the comparison between rs619586 GG and AA genotype in ever drinking subgroup. Conclusion:Taken together, our findings proposed that polymorphism rs3200401 C > T in MALAT1 gene is associated with increased risk of ESCC. Since the association between rs619586 A > G polymorphism and ESCC risk was not significant after FDR adjustment, there was a minor possibility that rs619586 A > G might be a protective factor for ESCC.
