    Abstract:
    OBJECTIVE: To investigate the association of TGF beta1 and AT1R gene polymorphisms with hereditary susceptibility and clinical phenotype of HBV-induced liver cirrhosis. METHODS: Peripheral blood samples were collected from 102 patients with HBV-induced liver cirrhosis and 106 healthy blood donors. The polymorphisms of the promoter site -509C/T of TGF beta1 and 1166A/C of AT1R gene were determined by PCR-RFLP. RESULTS: The frequency of the homozygote CC of -509C/T of TGF beta1 gene in the group of liver cirrhosis was higher than that the control group (P<0.05); and the frequency rate of homozygote CC was higher in group C than in group A and group B of liver cirrhosis (P<0.05), but there was no significant difference in allele frequency among these group (P>0.05). There was no significant difference in genotypes and allele frequency of AT1R gene 1166A/C between the liver cirrhosis group and the control group (P>0.05). CONCLUSION: The polymorphism of the promoter site -509C/T of TGF beta1 gene is associated with hereditary susceptibility to liver cirrhosis and severity of HBV-induced liver cirrhosis; the polymorphism of AT1R gene 1166A/C is not associated with hereditary susceptibility to HBV-induced liver cirrhosis.
