Effect of nucleos(t)ide analogues therapy on HBsAg, intrahepatic HBV DNA and covalently closed circular DNA levels [PDF]

open access: yes, 2012
BACKGROUND: We aimed to study 1) the effects of 1-year nucleos(t)ide analogue (NA) therapy on HBsAg and covalently closed circular DNA (cccDNA) levels; and 2) the possible use of HBsAg reduction as a marker for cccDNA reduction. METHODS: We recruited 124

PCR mediated recombination impacts the analysis of hepatitis B Virus covalently closed circular DNA [PDF]

open access: yes, 2016
International audienceBackground: The replication of HBV involves the production of covalently closed circular DNA (cccDNA) from the HBV genome through the repair of virion relaxed circular DNA (rcDNA) in the virion.

Covalently closed circular DNA: The ultimate therapeutic target for curing HBV infections

open access: yes, 2021
Current antiviral therapies, such as pegylated interferon-α and nucleos(t)ide analogues, effectively improve the quality of life of patients with chronic hepatitis B.

Hepatitis B Virus Covalently Closed Circular DNA Predicts Postoperative Liver Cancer Metastasis Independent of Virological Suppression

open access: yes, 2021
New antiviral therapies against hepatitis B virus (HBV) focus on the elimination of covalently closed circular DNA (cccDNA). However, traditional cccDNA-specific quantitative PCR (qPCR) has a narrow effective range, hindering a reliable comparison ...

A Sensitive and Specific PCR-based Assay to Quantify Hepatitis B Virus Covalently Closed Circular (ccc) DNA while Preserving Cellular DNA

open access: yesBio-Protocol, 2021
Hepatitis B virus (HBV) is the major cause of liver diseases and liver cancer worldwide. After infecting hepatocytes, the virus establishes a stable episome (covalently closed circular DNA, or cccDNA) that serves as the template for all viral transcripts.

Concerted action of activation-induced cytidine deaminase and uracil-DNA glycosylase reduces covalently closed circular DNA of duck hepatitis B virus [PDF]

open access: yes, 2013
Covalently closed circular DNA (cccDNA) forms a template for the replication of hepatitis B virus (HBV) and duck HBV (DHBV). Recent studies suggest that activation-induced cytidine deaminase (AID) functions in innate immunity, although its molecular ...

IL6 Inhibits HBV Transcription by Targeting the Epigenetic Control of the Nuclear cccDNA Minichromosome. [PDF]

open access: yesPLoS ONE, 2015
The HBV covalently closed circular DNA (cccDNA) is organized as a mini-chromosome in the nuclei of infected hepatocytes by histone and non-histone proteins.

Mechanism of Hepatitis B Virus cccDNA Formation

open access: yesViruses, 2021
Hepatitis B virus (HBV) remains a major medical problem affecting at least 257 million chronically infected patients who are at risk of developing serious, frequently fatal liver diseases.

Detection of HBV Covalently Closed Circular DNA

open access: yes, 2017
Chronic hepatitis B virus (HBV) infection affects approximately 240 million people worldwide and remains a serious public health concern because its complete cure is impossible with current treatments.
