Abstract
Hepatitis B virus (HBV) is an obligate human hepatotropic DNA virus causing both transient and chronic infection. The livers of chronic hepatitis B patients have a high risk of developing liver fibrosis, cirrhosis, and hepatocellular carcinoma. The nuclear episomal viral DNA intermediate, covalently closed circular DNA (cccDNA), forms a highly stable complex with host and viral proteins to serve as a transcription template and support HBV infection chronicity. Thus, characterization of the composition and dynamics of cccDNA nucleoprotein complexes providing cccDNA stability and gene regulation is of high importance for both basic and medical research. The presented method for chromatin immunoprecipitation coupled with qPCR (ChIP-qPCR) allows to assess provisional physical interaction of the protein of interest (POI) with cccDNA using POI-specific antibody, the level of enrichment of a POI on cccDNA versus control/background is characterized quantitatively using qPCR.
