Abstract:
Objective To investigate the role of Gly82Ser polymorphism of receptor for advanced glycation end-products (RAGE) in the genesis and progression of colon cancer in Chinese population.Methods Using the method of PCR-restriction fragment length polymorphism (PCR-RFLP),the Gly82Ser genotype of RAGE were examined in 90 colon cancer patients and 78 control subjects age and sex matched.Analyses stratified by TNM and tumor differentiation were conducted to check the associations of the Gly82Ser gene polymorphisms in RAGE and development of colon cancer.Results The genotype distribution was in agreement with that predicted under Hardy-Weinberg equilibrium for both patients and controls (both P ＞ 0.05).With the GG genotype as reference,the odds ratio (OR) for heterozygous GG and carriers with S allele (GS and SS) were 2.037 (95％ CI:1.207-3.438) and 2.022 (95％ CI:1.275-3.208),respectively,which had a significantly higher risk of colon cancer.Moreover,the elevated colon cancer risk was especially evident in patients with TNM (Ⅲ + Ⅳ) and/or patients with poor differentiation by stratification analysis (OR,3.575,95％ CI:1.495-8.550 and OR,3.580,95％ CI:1.390-9.217,respectively).Conclusions The RAGE Gly82Ser polymorphism may confer not only an increased risk of colon cancer but also with invasion of colon cancer in the Chinese population.
