OBJECTIVE Improper usage of acetaminophen (APAP) leads to morbidity and also mortality secondary to liver damage. Ginseng could suppress APAP-induced hepatotoxicity and ginsenoside Rg3 is a kind of major component in ginseng against liver damage. Herein, we intended to estimate the beneficial function and molecular mechanism of Rg3 on APAP-caused hepatotoxicity and identified hepatoprotection. METHODS A total of 50 C57BL/6J mice were divided into five random groups, and each contains 10 mice as the control, acetaminophen (350 mg/kg) and Rg3 (5, 10 and 20 mg/kg) + acetaminophen (350 mg/kg) groups. These mice were intragastric administration a single dose of acetaminophen by oral treatment behind pre-administered with several doses of ginsenoside Rg3 for six hours. RESULTS According to our data, the injection of APAP (350 mg/kg) enhanced the basal levels of alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase and lactic dehydrogenase. However, these abnormal added were alleviated by Rg3. Moreover, Rg3 treatment obviously relieved APAP-caused inflammation and oxidant in liver tissues. The depletion of glutathione, glutathione peroxidase, total antioxidant capacity and generation of malondialdehyde induced by APAP treatment were reduced by Rg3. By H&E staining, Rg3 effectively reduced APAP-caused apoptosis and inflammatory infiltration. Moreover, Rg3 attenuated APAP-caused hepatic damage in part by regulating the pro-inflammatory and anti-inflammatory cytokines. Moreover, we found that Rg3 could bind to NLRP3 suggesting the anti-inflammatory effects of Rg3 by molecular docking study. CONCLUSIONS In summary, Rg3 showed hepatic protective function in APAP-induced hepatotoxicity as evidenced by a reduction of the oxidant and the inflammatory reply, relieve of hepatocellular damage, showing potential in Rg3 as a potential therapeutic medicine to prevent hepatic injury.

D016207 Cytokines Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. Cytokine
D017209 Apoptosis A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, i.e., DNA FRAGMENTATION. It is genetically programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
