Molecular Mechanisms Behind the Inhibitory Effects of Ginsenoside Rg3 on Hepatic Fibrosis: a Review

Hepatitis is a chronic inflammatory liver disease and an important cause of liver fibrosis, which can progress to cirrhosis and even hepatocellular carcinoma if left untreated. However, liver fibrosis is a reversible disease, so finding new intervention targets and molecular markers is the key to preventing and treating liver fibrosis. Ginseng, the roots of Panax ginseng C. A. Meyer, is a precious Traditional Chinese Medicines with high medicinal value and is known as the "king of all herbs", and its active ingredient, ginsenoside Rg3 is a rare saponin and a new class of drug, one of the most thoroughly and extensively studied in a large number of studies. Ginsenoside Rg3 is an active ingredient extracted from ginseng that possesses a variety of biological activities, including anti-inflammatory, antioxidant, and anti-fibrotic effects. Several studies have suggested that ginsenoside Rg3 may help reduce hepatic inflammation and oxidative stress, thereby slowing the progression of liver fibrosis. Ginsenoside Rg3 may have some therapeutic effects on liver fibrosis, and the underlying molecular mechanisms behind these effects are attributed to cellular autophagy, apoptosis, and anti-inflammation, as well as the modulation of antioxidant activity and multiple signaling pathways. The molecular mechanisms behind the inhibitory effect of ginsenoside Rg3 on hepatic fibrosis are reviewed, with a view to providing reference for related studies.
