Expression of Hepatitis B Virus Core Antigen in Native and Fusion Forms in E. coli
DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
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 کاملDeep sequencing of hepatitis B virus basal core promoter and precore mutants in HBeAg-positive chronic hepatitis B patients
Mutants in the basal core promoter (BCP) and precore (PC) regions of hepatitis B virus (HBV) genome are associated with the progression of chronic hepatitis B (CHB) infection. However, quasispecies characteristics of naturally occurring mutants in those regions in HBeAg-positive CHB patients has not been well described, partly limited by quantitative assay. This study aimed to develop an Ion To...
متن کاملComparison of Serum Hepatitis B Virus DNA and HBsAg Levels Between HBeAg-Negative and HBeAg-Positive Chronic Hepatitis B Patients
BACKGROUND Chronic hepatitis B consists of different clinical phases. Laboratory and histological assessments can help differentiate the clinical phases of this disease and thus lead to better management. OBJECTIVES This study was conducted to determine laboratory and histological characteristics of HBeAg-negative and HBeAg-positive chronic hepatitis B patients. PATIENTS AND METHODS In this...
متن کاملSignificance of Hepatitis B Core Antibody as the Only Marker of Hepatitis B Virus Infection in High Risk Patients
Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the onl...
