Abstract:
Objective To investigate an association between Toll-like receptor(TLR)4 Asp299Gly or CD14 C-260T polymorphisms and colorectal cancer in Chinese patients.Methods By a method of polymerase chain reaction-based restriction fragment length polymorphism(PCR-RFLP), TLR4 Asp299Gly and CD14 C-260T polymorphisms in unrelated 110 patients with colorectal cancer and 160 healthy controls in Chinese Han race population were genotyped.Results Significant differences of CD14 genotypes were found between healthy controls and the patients with colorectal cancer.The fre- quency of the CC genotype in healthy controls was extremely lower than that in the group of colorectal cancer(15.6% vs.31.8%,P=0.0027,OR=0.3968,95%CI:0.2209-0.7129)while the frequency of the CT genotype in healthy controls was significantly higher than that in the group of colorectal cancer (48.1% vs.30.9%,P=0.0056,OR=2.074,95%CI:1.246-3.452).No TLR4 Asp299Gly mutant genotype was detected in any patients and healthy controls in Chinese Han population.Conclusion The polymorphism of CD14 C-260T but not TLR4 Asp299Gly is associated with colorectal cancer in Chinese patients.
