Abstract: Objective To determine the effect of aristolochic acid I (AAI) on the liver metabolic enzymes of mice and the associated mechanism using metabolic kinetics and related techniques. Methods Male 6-week-old C57BL/6 mice were assigned to four treatment groups and one control group. Established doses of AAI (0.2, 2, 10, and 20 mg/kg) were administered intragastrically 5 days per week for 4 weeks. The effects of AAI on liver metabolic enzymes were determined using metabolic kinetics and molecular biology techniques. Results AAI induced enzyme activities and mRNA expressions of liver cyp1a2 and cyp3a11, and increased the content of indoxylsulfuric acid by inducing sulfotransferase (SULT1B1). However, renal toxicity induced by AAI was the main cause of the accumulation of indoxylsulfuric acid in the plasma, liver, and kidney, which in turn aggravated the renal toxicity caused by AAI. Conclusion AAI has multiple effects on liver metabolic enzymes in mice.
