Aloperine attenuates carbon tetrachloride-induced mouse hepatic injury via Nrf2/HO-1 pathway
Abstract
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.
