Hepatitis B virus (HBV) persists by depositing a covalently closed circular DNA (cccDNA) in the nucleus of infected cells that cannot be targeted by available antivirals. Cytokine treatments can diminish HBV cccDNA via APOBEC3-mediated deamination. Here we show that overexpression of APOBEC3A alone,...

Binding of Nucleolin to HBV cccDNA
: Hepatitis B virus (HBV) remains a major public health threat with more than 296 million people chronically infected worldwide at high risk to develop hepatocellular carcinoma. Current therapies are effective in suppressing HBV replication but rarely lead to cure. The fundamental limitation rests o...

Hepatitis B virus core protein is not required for cccDNA transcriptional regulation
HBV cccDNA Generated Using Single-Stranded M13 Phage DNA for Authentic Minichromosome Functionality
Covalently closed circular DNA (cccDNA) forms the basis for replication and persistence of hepatitis B virus (HBV) in the chronically infected liver. In this study we sought to identify host factors interacting with the HBV genome. Nucleolin (Ncl) was identified as a potential interactor of HBV cccD...

CTCF regulates hepatitis B virus cccDNA chromatin topology [RNA-seq]
CTCF regulates hepatitis B virus cccDNA chromatin topology [ATAC-seq]
Background & Aims: Hepatitis B virus (HBV) infection is a major health burden worldwide and currently there is no cure. The persistence of HBV covalently closed circular DNA (cccDNA) is the major obstacle for antiviral treatment. HBV core protein (HBc) has merged as a promising antiviral target, as ...
