Saffron reduces the liver fibrosis in mice by inhibiting the JAK/STAT3 pathway

Area of Science:

• Pharmacology
• Hepatology
• Natural Products

Background:

• Chronic liver inflammation is a primary driver of liver injury and fibrosis.
• Saffron possesses known anti-inflammatory and antioxidant properties.

Purpose of the Study:

• To investigate the pharmacological effects of Saffron on hepatic inflammation and fibrosis.
• To explore Saffron's potential as a therapeutic agent for liver disease.

Main Methods:

• A carbon tetrachloride (CCl4)-induced mouse model of hepatic fibrosis was utilized.
• Saffron was administered orally at low (10 mg/kg) and high (20 mg/kg) doses.
• Liver function, inflammation, and fibrosis markers were assessed; in-vitro studies examined effects on hepatic stellate cells.

Main Results:

• Saffron administration dose-dependently improved liver function, reduced liver inflammation, and attenuated liver fibrosis.
• Western blotting revealed significant inhibition of JAK/STAT3 phosphorylation in fibrotic livers.
• In-vitro experiments confirmed Saffron's inhibitory effects on hepatic stellate cell activation.

Conclusions:

• Saffron effectively attenuates liver fibrosis by inhibiting the JAK/STAT3 pathway and hepatic stellate cell activation.
• These findings provide a scientific basis for developing Saffron-based anti-fibrotic drugs.
• Saffron shows promise as a natural therapeutic for liver fibrosis.
