Objective: To find new protein biomarkers for the detection and evaluation of liver injury and to analyze the relationship between such proteins and disease progression in concanavalin A (Con A)-induced hepatitis.

Methods: Twenty-five mice were randomly divided into five groups: an untreated group, a control group injected with phosphate buffered saline (PBS), and groups with Con A-induced hepatitis evaluated at 1, 3 and 6 h. Two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS) were used to identify differences in protein expression among groups. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to verify the results.

Results: In mice with Con A-induced hepatitis, expression levels of four proteins were increased: RIKEN, fructose bisphosphatase 1 (fbp1), ketohexokinase (khk), and Chain A of class pi glutathione S-transferase. Changes in fbp1 and khk were confirmed by qRT-PCR.

Conclusion: Levels of two proteins, fbp1 and khk, are clearly up-regulated in mice with Con A-induced hepatitis.

Background: Autoimmune hepatitis (AIH) is an autoimmune disease accompanied by an autoimmune inflammatory response that often leads to severe liver damage. In addition, it may further lead to complications such as liver fibrosis, cirrhosis and liver failure. Dihydromyricetin (DHM) possesses various pharmacological properties, such as being anti-inflammatory, antioxidant, and antibacterial.

Background: As cell-free nanotherapeutics, extracellular vesicles derived from mesenchymal stem cells (MSC-EVs) have shown potential therapeutic action against liver diseases. However, their effects on autoimmune hepatitis (AIH) are not yet well understood.

Methods And Results: In this study, we utilized a well-established concanavalin A (Con A)-induced fulminant hepatitis mouse model to investigate the effects of MSC-EVs on AIH.

Rhoifolin (ROF) exhibits a diverse range of biological activities, encompassing anticancer, hepatoprotective, antidiabetic, antirheumatic, and antiviral properties. However, the specific protective effects and possible mechanisms of the compound against T-cell-mediated autoimmune hepatitis have not been previously elucidated. In the present study, adult male mice were administered Con A (20 mg/kg, intravenously) for 8 h.

Article Synopsis
  • Chronic HBV infection leads to severe liver disease and liver cancer, and new antiviral treatments like Capsid Assembly Modulators (CAMs) are needed but not fully understood in their mechanism of action.
  • Recent research demonstrates that CAM-A compounds reduce HBsAg levels and cause cell death in HBV-infected cells by promoting the aggregation of HBV core proteins (HBc) in the nucleus, triggering apoptosis.
  • Discovering that CAM-A facilitates HBc aggregation and activates apoptosis provides insights for developing new therapies aimed at effectively managing chronic HBV infections.

Article Synopsis
  • The study explores the role of DDX3X, a protein, in immune-mediated liver injury, particularly in conditions like autoimmune and viral hepatitis.
  • In experiments with mice, researchers found that a lack of DDX3X reduced liver damage and endoplasmic reticulum (ER) stress, while increasing DDX3X worsened liver injuries during experiments.
  • Elevated levels of DDX3X were also observed in patients with liver conditions, suggesting it could serve as a target for developing treatments against immune-mediated liver injury.
