Background: Ganoderma lucidum Polysaccharides (GLPS) were found to possess various pharmacological properties including anti-inflammatory and hepatoprotective activities. However, the effect and possible mechanism of GLPS treatment on liver injury have not yet been reported. Therefore, this study aimed to explore the potential anti-inflammatory and hepatoprotective effects and possible mechanism of GLPS in carbon tetrachloride (CCl4)-induced acute liver injury mice. Summary: GLPS significantly reduced the activation of NLRP3 inflammasome and improved liver function in liver injury mice. It significantly inhibited CCl4-induced changes of alanine aminotransferase and aspartate aminotransferase activities in serum, as well as nitric oxide synthase (NOS) and cytochrome P450 2E1 (CYP2E1) activities in liver tissue; it also remarkably decreased levels of liver weight and index, total bilirubin, interleukin (IL)-1β, IL-18, IL-6 and tumor necrosis factor-α in serum, as well as malondialdehyde and IL-1β in liver tissue. Protein expression levels of liver NLRP3, ASC, and Caspase-1 were also downregulated, while the glutathione level in liver tissue was remarkably enhanced in GLPS groups compared to that of the model group. Key Message: These results suggested that GLPS may be a potential for the prevention and treatment of acute liver injury with liver inflammation. The possible mechanism may be related to the inhibition of free radical lipid peroxidation, NOS, and CYP2E1 activities and activation of liver inflammatory factors.

Nlrp3 Inflammasome Activation

NLRP3 inflammasome activation results in severe liver inflammation and injury. Saikosaponin-d (SSd) possesses anti-inflammatory and hepatoprotective effects. This study aimed to determine the protective effects of SSd on carbon tetrachloride (CCl4)-induced acute liver injury in mice, and whether oxidative stress and NLRP3 inflammasome activation participate in the process. The CCl4 mice model and controls were induced. The mice were treated with SSd at 1, 1.5, or 2.0 mg/kg in a total volume of 100 µl/25 g of body weight. Liver injury was assessed by histopathology. Oxidative stress was determined using mitochondrial superoxide production (MSP), malondialdehyde (MDA) content, and superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activities. NLRP3, ASC, and Caspase 1 were determined by real-time PCR and western blot. IL-1β and IL-18 levels were determined by ELISA. Significantly elevated oxidative stress was induced in the liver by CCl4, as demonstrated by histopathology and increases of MDA and MSP levels and decreases of SOD, GPx, and CAT activities (all P < 0.01). SSd significantly decreased the MDA and MSP levels and increased the activities of SOD, GPx, and CAT (all P < 0.05). The mRNA expression of NLRP3, ASC, and Caspase 1, and the protein expression of Caspase 1-p10, NLRP3, ASC, IL-1β, and IL-18 were significantly increased after CCl4 induction (all P < 0.01). These changes were reversed by SSd (all P < 0.05). Suppression of the oxidative stress and NLRP3 inflammasome activation were involved in SSd-alleviated acute liver injury in CCl4-induced hepatitis.

Purpose: To investigate whether aloperine pretreatment ameliorates acute liver injury in carbon tetrachloride (CCl4)-treated mice.Methods: Mice were injected with CCl4 and orally administered aloperine. Blood samples and liver tissues were used for histopathological and biochemical analyses, respectively. Protein expression levels were determined by western blotting.Results: Histopathological analysis indicate that aloperine pretreatment significantly alleviated CCl4- induced mouse hepatic injury. CCl4 treatment induced the upregulation of aspartate aminotransferase (AST), alkaline phosphatase (ALP), alanine amino transferase (ALT), and total bilirubin (p < 0.05). However, these alterations were significantly inhibited by aloperine treatment. Moreover, aloperine pretreatment markedly decreased (p < 0.05) the CCl4-induced expression of oxidative stress biomarkers, including malondrialdeline (MDA), glutathione (GSH), catalase (CAT), and  superoxide dismutase (SOD). Compared to the control group, the protein levels of Nrf2, HO-1, iNOS, and COX-2 were significantly increased in the CCl4 group, while Nrf2 and HO-1 were upregulated. Furthermore, iNOS and COX-2 were downregulated in mouse liver in CCl4 + aloperine group compared to CCl4 group in a concentration-dependent manner (p < 0.05).Conclusion: Aloperine pretreatment appears to markedly upregulate Nrf2 and HO-1 and downregulate iNOS and COX-2 to suppress hepatic injury in mice. Thus, aloperine is a promising treatment for acute liver injury. Keywords: Hepatic injury, Aloperine, Oxidative stress, Nrf2/HO-1 pathway

This study investigates the protective effect of baicalein on carbon tetrachloride (CCl4)-induced acute liver injury and the underlying molecular mechanisms. Mice were orally administrated baicalein at 25 and 100 mg/kg/day for 7 consecutive days or ferrostatin-1 (Fer-1) at 10 mg/kg was i.p. injected in mice at 2 and 24 h prior to CCl4 injection or the vehicle. Our results showed that baicalein or Fer-1 supplementation significantly attenuated CCl4 exposure-induced elevations of serum alanine aminotransferase and aspartate aminotransferase, and malondialdehyde levels in the liver tissues and unregulated glutathione levels. Baicalein treatment inhibited the nuclear factor kappa-B (NF-κB) pathway, activated the erythroid 2-related factor 2 (Nrf2)/heme oxygenase 1 (HO-1) pathway in liver tissues, and markedly improved CCl4-induced apoptosis, inflammation and ferroptosis in liver tissues exposed with CCl4. In vitro, baicalein treatment improved CCl4 -induced decreases of cell viabilities and knockdown of Nrf2 and arachidonate 12-lipoxygenase (ALOX12) genes partly abolished the protective effect of baicalein on CCl4 -induced cytotoxicity in HepG2 cells. In conclusion, our results reveal that baicalein supplementation ameliorates CCl4-induced acute liver injury in mice by upregulating the antioxidant defense pathways and downregulating oxidative stress, apoptosis, inflammation and ferroptosis, which involved the activation of Nrf2 pathway and the inhibition of ALOX12 and NF-κB pathways.
