Effects of ethanol on HBV gene mutations in patients with chronic hepatitis B by gene chip / 中国病理生理杂志

ABSTRACT

AIM: To study ethanol influence on gene mutations of HBV DNA and to offer testimony for clinical diagnosis and treatment of chronic hepatitis B.METHODS: 85 patients with chronic hepatitis B were divided into alcoholic group and non-alcoholic group.Gene chip technique was used to detect gene mutations located in Pre-C nt G1896A and nt A1814C,basal core promoter(BCP) nt A1762T and nt G1764A,P nt C528A and nt T552C.RESULTS: The mutation frequency on BCP nt A1762T and nt G1764A in alcoholic group was significantly higher than that in non-alcoholic group(P0.05).CONCLUSION: Ethanol stimulates HBV gene mutations on BCP nt A1762T and nt G1764A,enhances HBV DNA replication and gene expression,deteriorates the state of the illness.
