Ginsenoside Rg2 Attenuates Aging-Induced Liver Injury via Inhibiting Caspase 8-Mediated Pyroptosis, Apoptosis and...

Area of Science:

• Gerontology
• Hepatology
• Pharmacology

Background:

• Aging is a natural process linked to chronic diseases, including liver dysfunction.
• Panax Ginseng and its active compound, Ginsenoside Rg2, have historical medicinal uses, including liver protection.
• The role of Ginsenoside Rg2 in ameliorating aging-induced liver injury is not well understood.

Purpose of the Study:

• To investigate the potential of Ginsenoside Rg2 in alleviating liver injury associated with aging.
• To elucidate the molecular mechanisms underlying Rg2's hepatoprotective effects in aged mice.
• To explore the influence of Rg2 on the gut microbiota and its impact on the gut-liver axis.

Main Methods:

• Utilized Senescence Accelerate Mouse Prone 8 (SAMP8) mice to model aging-induced liver injury.
• Administered Ginsenoside Rg2 to aged mice and assessed liver health markers.
• Analyzed changes in gut microbiota composition and gut-liver axis regulation.
• Investigated the inhibition of pyroptosis and apoptosis via caspase 8 signaling.

Main Results:

• Ginsenoside Rg2 significantly improved aging-induced liver injury in SAMP8 mice.
• Rg2 demonstrated the ability to inhibit pyroptosis and apoptosis by targeting caspase 8.
• The compound modulated the gut-liver axis by altering gut microbiota composition, thereby reducing liver inflammation.

Conclusions:

• Ginsenoside Rg2 possesses significant hepatoprotective effects against aging-induced liver injury.
• Rg2's mechanism involves the inhibition of programmed cell death pathways and regulation of the gut-liver axis.
• These findings support the use of ginsenosides for their anti-aging properties and potential in managing age-related liver diseases.
