The association between PIN1 genetic polymorphisms and the risk of chronic hepatitis B and hepatitis B virus-related liver cirrhosis: A case-control study.

ABSTRACT: Peptidyl-prolyl cis/trans isomerase NIMA-interacting 1 (PIN1) reportedly plays a crucial role in tissue inflammation and tumourigenesis. Our previous studies have demonstrated that PIN1 gene polymorphisms are significantly related to the pathogenesis of hepatitis B virus (HBV)-related liver cancer in a Guangxi population. As chronic hepatitis B (CHB), liver cirrhosis (LC), and liver cancer are development processes, we further investigated whether any relationship exists between PIN1 gene polymorphisms and the risk of CHB and HBV-related LC. We used the polymerase chain reaction restriction fragment length polymorphism and the deoxyribonucleic acid sequencing method to analyze 3 common single-nucleotide polymorphisms (SNPs) (rs2233678, rs2233679, and rs2233682) of the PIN1 gene in 192 CHB patients, 171 HBV-related LC patients, and 201 healthy controls in this research. The results revealed that carriers of the rs2233682 A allele had a significantly decreased risk of HBV-related LC (LC vs. controls: odds ratio [OR]?=?0.262, 95% confidence interval [CI]?=?0.071-0.959, P?=?.043; LC vs. CHB: OR?=?0.198, 95% CI?=?0.049-0.803, P?=?.023). Similar relationships were observed for the PIN1 rs2233682 GA genotype among the groups (LC vs. controls: OR?=?0.248, 95% CI?=?0.067-0.919, P?=?.037; LC vs. CHB: OR?=?0.184, 95% CI?=?0.044-0.773, P?=?.021). This reduced risk was more obvious in older CHB patients (age ?50 years). No such correlations were found for PIN1 rs2233678 and rs2233679. However, the haplotypes constructed from these SNP (GCA for controls and CCG for CHB) were associated with a significantly decreased risk of HBV-related LC. In summary, the findings of this study suggest that the PIN1 rs2233682 A allele might be related with a decreased risk of HBV-related LC in a Guangxi population.

Project description:Reactive oxygen species (ROS) play critical roles in hepatocarcinogenesis. The catalase (CAT) enzyme is involved in the repair of ROS. Therefore, we investigate the association between CAT gene polymorphisms and the risk of hepatocellular carcinoma (HCC). A total of 715 subjects were divided into 4 groups: 111 chronic hepatitis B (CHB) patients, 90 hepatitis B virus (HBV)-related liver cirrhosis (LC) patients, 266 HBV-HCC patients, and 248 healthy controls. The polymerase chain reaction-restriction fragment length polymorphism strategy was used to detect CAT gene rs1001179, rs769217, and rs7943316 polymorphisms. Binary logistic regression analyses adjusting for sex, age, ethnicity, smoking and alcohol consumption, and body mass index suggested that subjects carrying the rs769217 T allele were at marginally increased risk of CHB, LC, and HCC, with adjusted odds ratios (ORs) of 1.51 (95% confidence interval [CI] = 1.04-2.20, P = 0.029), 1.48 (95% CI = 1.03-2.14, P = 0.035), and 1.51 (95% CI = 1.14-1.98, P = 0.004), respectively. Similarly, those individuals carrying the rs769217 TT genotype had a moderately increased risk of CHB, LC, and HCC, with adjusted ORs of 2.11 (95% CI = 1.05-4.22, P = 0.035), 2.00 (95% CI, 1.01-3.95, P = 0.047), and 1.93 (95% CI = 1.14-3.28, P = 0.015), respectively. Moreover, subjects carrying the rs769217 CT genotype and at least 1 copy of the T allele (dominant model) were 1.78 times and 1.83 times more likely to develop HCC, respectively (OR = 1.78, 95% CI = 1.16-2.73, P = 0.009 and OR = 1.83, 95% CI = 1.23-2.71, P = 0.003). This association between CAT rs769217 T alleles and HCC risk is significantly strengthened among men, nonsmokers, nondrinkers, and among individuals <50 years of age. Furthermore, we found 1 high-risk haplotype GTA for CHB (OR = 1.45, 95% CI = 1.05-2.01) and 1 protective haplotype GCA for HCC risk (OR = 0.67, 95% CI = 0.52-0.87). We did not found any significant difference in CAT rs1001179 and rs7943316 polymorphisms between controls and cases. Our findings suggest that the CAT rs769217 T allele is associated with increased risk of CHB, HBV-LC, and HBV-HCC in Guangxi population.
