Fibrinogen superfamily proteins regulate liver health, offering protection but also driving disease when overactive. Targeting these proteins, like FGL1, shows promise for treating liver diseases and cancer.
Area of Science:
- Hepatology
- Molecular Biology
- Immunology
Background:
- Liver diseases pose global health challenges.
- Fibrinogen (FG) superfamily proteins (FG, FGL1, FGL2) impact liver regeneration, metabolism, and cancer.
- Their role in hepatic disorders requires systematic examination.
Purpose of the Study:
- To review the pathophysiological links between FG superfamily proteins and major liver diseases.
- To elucidate the dual regulatory roles of these proteins in hepatic health and disease.
- To highlight their therapeutic potential in managing liver conditions.
Main Methods:
- Systematic review of existing literature.
- Analysis of molecular mechanisms.
- Examination of pathophysiological correlations.
Main Results:
- FG superfamily proteins have hepatoprotective roles in regeneration and matrix remodeling.
- Overactivation paradoxically promotes inflammation, metabolic dysfunction, and cancer progression.
- Specific roles in hepatitis, fatty liver disease, and hepatocellular carcinoma are detailed.
Conclusions:
- FG superfamily proteins exhibit dual roles in liver pathophysiology.
- Targeting the FGL1/lymphocyte activation gene 3 axis is a novel immunotherapy strategy.
- These proteins represent potential therapeutic targets for liver diseases and cancer.

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
