ABSTRACT
The present study investigates the hepatoprotective activity of Myrica rubra Sieb. et Zucc. extract (MCE) against acetaminophen (AAP)-induced liver damage and elucidates the possible mechanisms behind the hepatoprotection observed. Serum alanine aminotransferase and serum aspartate aminotransferase activities were detected and liver histopathology was observed. Mitochondrial swelling, mitochondrial membrane potential, and voltage-dependent anion channel (VDAC) gene transcription were also investigated. The results showed that 50, 150, and 450 mg/kg MCE could restore AAP-induced changes in mice liver in a dose-dependent manner. The mechanisms behind the hepatoprotective effects of MCE may be related to the mitochondrial protection of liver cells, especially of VDAC, an important protein on the outer membrane of the mitochondria.
