| Popis: | Ethnopharmacological relevance San Wei Gan jiang San (SWGJS) also called Jia Ga Song Tang, is widely used in ancient medicine for liver diseases. The aim of this study To identify the blood components of SWGJS. To determine the hepatoprotective effect and the mechanism of SWGJS by observing its effect on different degrees of liver damage and gene knockdown cells. Materials and methods SWGJS treated serum was analyzed by UPLC-MS to identify blood components. CCl4-induced chronic liver injury in rats was treated with SWGJS. The viscera index was calculated. Pathological changes of the liver were determined by HE staining and analysis of by following: GSH-Px and MDA in liver homogenate; ALT and AST in serum; mRNA expression of Nrf2, Bach1, and HO-1 by RT-PCR; Nrf2 and Bach1 in the nucleus and cytoplasm; HO-1 total expression by Western blot; silencing Nrf2 and Bach1 in human L-02 cells by siRNA; MDA, GSH-Px, GST, and GR in cell supernatants; and GSH/GSSG within the cell. Results We found that 6-gingerol was one of the blood components in the serum treated with SWGJS. In CCl4-induced chronic liver injury in rats, SWGJS repaired the liver structure in the early stages of liver damage as evidenced by reduced ALT and AST in the serum, increased GSH-Px activity and decreased MDA levels in the liver over time. SWGJS has excellent antioxidant and hepatoprotective effects and prevents disease progression. The mechanism of SWGJS is related to the dynamics promoting Nrf2 entry to the nucleus and Bach1 exit from the nucleus. In L-02 cells with silenced Nrf2, the antioxidant enzyme system was disordered, and the change in the cellular redox state was not conducive to antioxidative stress. However, in cells with silenced Bach1, the antioxidant enzyme system could be activated to promote cellular antioxidant stress. SWGJS had a combined effect on Nrf2 and Bach1 contributing to antioxidant properties and liver protection. SWGJS increased GSH-Px and HO-1, decreased MDA and increased the ratio of GSH/GSSG by upregulating the expression of Nrf2 to enhance its antioxidant effects. At the same time, SWGJS had a specific impact on decreasing Bach1. Its elevation of GST is due to the overall performance of increasing Nrf2 and decreasing Bach1. This mechanism of action embodies the characteristics of the multitarget impact of traditional medicine and the antioxidation effect of SWGJS. Conclusions 6-Gingerol is one of the blood components of SWGJS. SWGJS can regulate antioxidant enzymes, protect against liver damage in different stages, and slow the progression of liver cell damage and liver disease by increasing Nrf2 and reducing Bach1 in the nucleus, dynamically regulating Nrf2/Bach1. |
