2、Virus-associated gastric carcinoma in northernAbstractObjective: The aim of our study was to evaluate the potential associations betweenthe SNPs of TLR genes and the risk of GC, especially to EBVaGC.Methods: The TLR2, TL

3、R4 and TLR9 genes polymorphism were assessed by poly-merase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 185cases of EBVnGC, 43 cases of EBVaGC. 100 cases of peripheral blood samples fromhealthy

4、individuals were also examined. And Genotyp of some samples wereanalyzed by PCR and sequencing. the data was analysed by SPSS.Results: As for the TLR2 gene rs3804099 and TLR4 gene rs10759932, there weresignificant differ

5、ences between the GC group and the control group in both genotypeand allelic frequency. As for TLR2 gene rs3804100 and TLR4 gene rs11536889, therewere no association between the GC group and control. As for TLR91486T/C(r
