Abstract:
OBJECTIVECDH1, encoding E-cadherin, is an important tumor suppressor gene. The present study aims to investigate the association of -160(C-->A) polymorphism in CDH1 gene with susceptibility to gastric cancer in Fujian province.
METHODSOne hundred and two patients from independent families and 101 healthy control subjects were analyzed. Genotype analysis was performed through polymerase chain reaction-based denaturing high performance liquid chromatography. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by unconditional logistic regression model.
RESULTSThe frequencies of -160(C-->A) polymorphism CC, CA and AA genotype in case group and controls were 58(56.9%), 38(37.3%)ì6(5.9%) and 55(54.5%), 41(40.6%), 5(5%), respectively. AA genotype did not present a significantly increased risk for gastric cancer (OR=1.12; 95% CI:0.32-3.95). No association was found between A allele and clinicopathological characteristics of gastric cancer.
CONCLUSION-160(C-->A) polymorphism in CDH1 gene promoter region may not be in association with genetic susceptibility to gastric cancer in Chinese population from Fujian.
