Abstract:
Objective To investigate the relationship between single nucleotide polymorphisms (SNPs),serum CD31 and HCC.Methods We analyzed three single nucleotide polymorphisms of CD31 gene Leu125Val,Asn563Ser and Gly670Arg in 190 HCC patients and 210 age and sex matched controls in a Chinese population,using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy,and the serum level of CD31 was determined by enzyme-linked immunosorbent assay (ELISA).Results The distributions of CD31 gene Asn563Ser and Gly670Arg polymorphisms were not significantly different between HCC and control group (x2 =0.491,P ＞ 0.05),but the CD31 gene Leu125Val polymorphism was significantly different (x2 =10.988,P ＜ 0.05).The relative risk suffering from HCC of Val allele was 1.583 times of the Leu allele carriers(OR =1.583,95％ CI,1.197-2.093,P =0.001) ; Serum level of CD31 Val allele carriers was significantly higher than that of no carriers(x2 =10.408,P ＜ 0.05).Consistent with the results of the genotyping analyses,CD31 gene Leu125Val,Asn563Ser and Gly670Arg polymorphisms showed strong linkage disequilibrium,the Val-Ser-Arg haplotype was associated with a significantly increased risk of HCC as compared with the controls (OR =1.496,95％CI:1.095-2.046,P =0.011).Conclusions CD31 gene Leu125Val polymorphism and its Val-Ser-Arg haplotype were associated with HCC,Val allele is an important genetic susceptibility gene for HCC.CD31 Val allele carriers may subject to higher risk of HCC with enhanced CD31 expression.
