Puerarin Prevents Acute Liver Injury via Inhibiting Inflammatory Responses and ZEB2 Expression

Area of Science:

• Pharmacology
• Hepatology
• Immunology

Background:

• Puerarin, derived from Radix Puerariae, is used for immune diseases and inflammation.
• Puerarin has shown protective effects against acute lung injury.
• The impact of puerarin on acute liver injury (ALI) remained largely uninvestigated.

Purpose of the Study:

• To investigate the protective effects of puerarin in acute liver injury models.
• To elucidate the molecular mechanisms underlying puerarin's action in ALI.

Main Methods:

• Lipopolysaccharide (LPS)/D-galactose (D-Gal) induced ALI model in vivo.
• LPS-induced L-02 cell model for in vitro studies.
• Analysis of liver injury, inflammatory cell infiltration, pro-inflammatory cytokines (IL-1β, IL-6, TNF-α), ZEB2 expression, and NF-κB signaling pathway activation.

Main Results:

• Puerarin significantly inhibited liver injury and inflammatory cell infiltration in ALI models.
• Puerarin reduced pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) in liver tissues and L-02 cells.
• Puerarin upregulated Zinc Finger E-box-Binding Homeobox 2 (ZEB2) expression, which was crucial for inhibiting cytokine production and blocking NF-κB pathway activation.

Conclusions:

• Puerarin demonstrates beneficial effects in preventing and treating acute liver injury.
• ZEB2 upregulation by puerarin plays a key role in suppressing inflammatory responses.
• Puerarin exerts its hepatoprotective effects by inhibiting the NF-κB signaling pathway via enhanced ZEB2 expression.
