Mutations at Nucleotide 1762, 1764 and 1766 of Hepatitis B Virus X Gene in Patients with Chronic Hepatitis B and Hepatitis B-Related Cirrhosis
Abstract Background and objective: Hepatitis B virus (HBV) is a DNA virus with high tendency toward hepatic tissue. There are currently about 3 million HBV-infected people and 350 to 400 million chronic carriers of this virus in the world. X protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal co...
متن کاملhepatitis b virus core promoter mutations in patients with chronic hepatitis b and hepatocellular carcinoma in bucharest, romania
conclusions genotype d was the main genotype detected in romanian patients with chronic hbv infection. genotype d presented both bcp and pc mutations more frequently. results we detected two hbv genotypes; a (8.1%) and d (60.5%), and a mixture of genotypes a and d (31.4%) (p < 0.001). basal core promoter (bcp) a1762t/g1764a and precore (pc) g1896a mutations were detected in these romanian patie...
متن کاملMutations in pre-core and basal-core promoter regions of hepatitis B virus in chronic HBV patients from Golestan, Iran
Objective(s): It has been reported that the mutation of the pre-core (PC) and basal-core promoter (BCP) may play an important role in the development of HBV-related hepatocellular carcinoma (HCC). In this study the PC and BCP mutations were investigated in chronic HBV patients. Materials and Methods:In this study, 120 chronic HBV patients from Golestan, Northeast of Iran who were not vaccinated...
متن کاملYMDD and FLLAQ Mutations in Chronic Hepatitis B Patients
Abstract Background and Objective: Lamivudine is the first orally available drug approved for treatment of chronic hepatitis B. Mutations at the YMDD and FLLAQ motifs in the domains of HBV polymerase gene contribute resistance to lamivudine. This study was aimed to determine the rate of YMDD and FLLAQ mutants in hepatitis B patients in Golestan Province, Iran. Material and methods: In this cros...
متن کاملHepatitis B Virus Core Promoter Mutations in Patients With Chronic Hepatitis B and Hepatocellular Carcinoma in Bucharest, Romania
BACKGROUND Accurate and personalized molecular virological diagnosis of hepatitis B virus (HBV) infection is crucial for individualized selection of patients for antiviral therapy in Romania. OBJECTIVES We aimed to investigate HBV mutations in Romanian patients with chronic HBV infection, also to match HBV genotypes with HBV mutations identified and clinical outcomes. PATIENTS AND METHODS T...
