The Significance of cGAS‐STING Signaling in Response to Oncogenic Viruses

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT The cyclic GMP‐AMP synthase (cGAS)‐stimulator of interferon genes (STING) signaling pathway, as a key DNA sensor, plays a significant role in the regulation of innate immune responses. This pathway can be activated by sensing abnormal DNA, and is of great significance for resisting the invasion of pathogenic microorganisms and maintaining ...

Uracil DNA Glycosylase Counteracts APOBEC3G-Induced Hypermutation of Hepatitis B Viral Genomes: Excision Repair of Covalently Closed Circular DNA [PDF]

, 2013
The covalently closed circular DNA (cccDNA) of the hepatitis B virus (HBV) plays an essential role in chronic hepatitis. The cellular repair system is proposed to convert cytoplasmic nucleocapsid (NC) DNA (partially double-stranded DNA) into cccDNA in ...

Next‐Generation Sequencing Methods for Sensitive Hepatitis B Viral Genome Analysis: A European Study

Journal of Medical Virology, Volume 98, Issue 9, September 2026.
ABSTRACT This multicentre study investigated the utility of next‐generation sequencing (NGS) to detect and generate hepatitis B virus (HBV) genomes in samples of low viral load (from 0.2 to 6207 IU/mL). 23 HBV DNA‐positive plasma samples of genotypes A‐E and one HBV‐negative control sample were assayed blindly via 9 established NGS methods from 6 ...

A Role for the Host DNA Damage Response in Hepatitis B Virus cccDNA Formation—and Beyond?

Viruses, 2017
Chronic hepatitis B virus (HBV) infection puts more than 250 million people at a greatly increased risk to develop end-stage liver disease. Like all hepadnaviruses, HBV replicates via protein-primed reverse transcription of a pregenomic (pg) RNA ...

Quantitation of covalently closed circular hepatitis B virus DNA in chronic B patients

, 2004
This study examined a signal amplification assay, the Invader assay, for the quantitation of hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) in liver biopsies and sera.

Inflammatory Gene Expression Associates with Hepatitis B Virus cccDNA- but Not Integrant-Derived Transcripts in HBeAg Negative Disease

Viruses, 2022
Chronic hepatitis B virus (HBV) infection is a global health problem that presents as a spectrum of liver disease, reflecting an interplay between the virus and the host immune system. HBV genomes exist as episomal covalently closed circular DNA (cccDNA)

Incidence of Hepatitis B Virus Reactivation in Patients Treated With Immunosuppressive and Chemotherapeutic Agents

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 5, Page 625-634, September 2026.
HBV reactivation incidence varied across immunosuppressive and chemotherapeutic agents. Clinically meaningful HBV reactivation was also observed in patients receiving corticosteroids and conventional immunosuppressive therapies. ABSTRACT Background Data on the incidence of hepatitis B virus reactivation (HBVr) remain limited. In Japan, patients who are

G‐Quadruplexes: Structural Diversity and Emerging Roles in Biomolecular Condensation

Advanced Science, Volume 13, Issue 45, 13 August 2026.
G‐quadruplexes (G4s) fold into diverse intra‐ and intermolecular structures, positioning them as emerging regulators of biomolecular condensation. Mechanistically, G4s autonomously form condensates, act as structural platforms to initiate and stimulate condensation, or induce phase transitions.

Quantification of Pregenomic RNA and Covalently Closed Circular DNA in Hepatitis B Virus-Related Hepatocellular Carcinoma [PDF]

, 2013
Pregenomic RNA (pgRNA) is generated from covalently closed circular DNA (cccDNA) and plays important roles in viral genome amplification and replication. Hepatic pgRNA and cccDNA expression levels indicate viral persistence and replication activity. This

TRMT6‐Mediated m1A Modification of CDK9 mRNA is a Dual‐Pronged Pathogenic Driver for HBV‐Related Hepatocellular Carcinoma

Advanced Science, Volume 13, Issue 39, 13 July 2026.
TRMT6‐mediated m1A modification in CDK9 mRNA enhances its mRNA stability and translation efficiency, thereby increasing the protein levels of CDK9. Upregulated CDK9 promotes the progression of HCC by elevating the levels of oncogenic factors including p‐STAT3, MCL1, and BCL‐2. On the other hand, CDK9 phosphorylates TARDBP at Ser254 to activate HBV core
