Association of CD44 polymorphisms and susceptibility to HBV-related hepatocellular carcinoma in the Chinese population.

ABSTRACT: BACKGROUND:This study aimed to determine whether CD44 polymorphisms were correlated with hepatocellular carcinoma (HCC) and to reveal a new potential target for early prediction, prevention, and diagnosis of HCC. METHOD:This study involved 96 cases with chronic hepatitis B (CHB), 96 cases with hepatitis B virus-related liver cirrhosis (LC), 204 cases with HCC related to the hepatitis B virus, and 210 healthy controls. The genotype of rs8193 was determined using the restriction fragment length polymorphism method, while the genotypes of rs10836347 and rs13347 were determined by direct sequencing. RESULTS:The results showed that patients with the CD44 rs13347 TT and T allele polymorphisms exhibited higher risks of LC than those carrying the CC genotype and C allele. The CD44 rs13347 CT and TT genotypes and T allele were significantly associated with an increased risk of HCC after adjusting for gender, age, smoking, and alcohol consumption (for CT: odds ratio [OR] = 1.626, 95% confidence interval [CI] = 1.057-2.500, P = .027; for TT: OR = 1.965, 95% CI = 1.043-3.702, P = .037; and for T: OR = 1.461, 95% CI = 1.091-1.956, P = .011). In the rs13347 site of the female population, the CT and TT genotypes were related to the high occurrence of HCC. In the population aged ?50 years, carriers of the CD44 rs13347 CT and TT alleles were more susceptible to HCC compared with CC carriers. Those who consumed alcohol who carried the rs10836347 CT genotype exhibited a risk factor for HCC. CONCLUSION:For the CD44 rs13347 site, mutations in the T allele might be a risk factor for HCC.

Project description:BackgroundPolymorphisms of genes encoding components of the vitamin D pathway including vitamin D receptor (VDR) and vitamin D binding protein (DBP) have been widely investigated because of the complex role played by vitamin D in cancer tumorogenesis. In this study, we investigated the association between VDR and DBP gene polymorphisms and HBV-related HCC risk in a Chinese population.MethodsStudy subjects were divided into three groups: 184 HBV patients with HCC, 296 HBV patients without HCC, and 180 healthy controls. The VDR rs2228570, and rs3782905 and the DBP rs7041 polymorphisms were genotyped using PCR-RFLP and the VDR rs11568820 polymorphism was genotyped by PCR-SSP, respectively. DNA sequencing was performed to validate the genotype results.ResultsWe found that there were significant differences in the genotype and allele frequencies of the VDR rs2228570 and DBP rs7041 polymorphisms between HBV patients with HCC and healthy controls. The rs2228570 T allele was associated with a significant increased HBV-related HCC risk as compared with the C allele. The rs2228570 TT and TT/TC genotypes were correlated with a significant increased HBV-related HCC risk when compared with the wild-type CC homozygote. Similarly, the rs7041 G allele was associated with a significant increased HBV-related HCC risk as compared with the T allele. The rs7041 GG and GG/TG genotypes were correlated with a significant increased HBV-related HCC risk when compared with the wild-type TT homozygote. However, we did not observe any significant effect of VDR rs11568820, and rs3782905 polymorphisms on HBV-related HCC risk in this population. In haplotype analysis, we also did not find any significant differences in haplotype frequencies of the VDR gene between HBV patients with HCC and the healthy controls.ConclusionsWe conclude that the VDR rs2228570 and DBP rs7041 polymorphisms may contribute to increased susceptibility to HBV-related HCC in the Chinese population. Due to the marginal significance, further large and well-designed studies in diverse ethnic populations are needed to confirm our results.
