Estrogen receptor gene polymorphisms and HBV-induced liver cirrhosis / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To investigate the relationship between estrogen receptor (ER) gene polymorphisms and HBV-induced cirrhosis.@*METHODS@#Xba I and Pvu II polymorphisms of ER gene were analyzed in 98 patients with HBV-induced cirrhosis, 72 patients with chronic hepatitis B, and 84 healthy controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique.@*RESULTS@#The frequencies of Pp genotype and P allele of ER gene in patients with HBV-induced cirrhosis were higher than those in patients with chronic hepatitis B and controls, while the frequencies of pp genotype and p allele of ER gene in patients with HBV-induced cirrhosis were lower than those in patients with chronic hepatitis B and controls (P 0.05).@*CONCLUSION@#Pp genotype and P allele might be the susceptibility gene for HBV-induced cirrhosis while pp genotype and p allele might be the protective gene.
