QRICH1, HMGB1, and HBV-Associated Fibrosis
2026-09-22
The reference study identifies QRICH1 as an endoplasmic reticulum stress effector that amplifies HBV-associated HMGB1 transcription, acetylation, nuclear-to-cytoplasmic translocation, and secretion. By connecting QRICH1 with SIRT6-regulated HMGB1 signaling, the work provides a mechanistic framework for interpreting inflammatory progression and fibrosis in chronic hepatitis B.

Isochlorogenic Acid A Disrupts HBV via HO-1 and ROS
2026-09-15
The reference study shows that isochlorogenic acid A (ICAA) suppresses HBV through coordinated effects on cccDNA-associated replication, viral gene expression, capsid assembly, and envelopment. Its mechanistic contribution is the connection of HO-1 induction and intracellular ROS modulation with altered viral structural-protein chemistry, providing a framework for evaluating host-directed antiviral strategies.
