The regulation mechanism of arecoline on rat hepatic CYP2E1 was studied in vivo. After oral administration of arecoline hydrobromide (AH; 4, 20 and 100 mg x kg(-1) x d(-1)) to rats for one week, the hepatic CYP2E1 mRNA level remained unchanged, but the hepatic CYP2E1 protein content was dose-dependently increased. Additionally, although the hepatic CYP2E1 activity was induced by AH treatment, the induction was attenuated with the increase in dosage.

Betel-quid use is associated with the risk of liver cirrhosis and hepatocellular carcinoma. The aim of the present work was to evaluate the impact of arecoline on human hepatic cytochrome P450 (CYP) enzymes in vitro and rat hepatic CYP enzymes, as well as the hepatic oxidative stress and liver injury of rats in vivo. The in vitro results indicated that arecoline hydrobromide (AH) has no significant effect on the activities of CYP2B, 2C9, 3A4, 1A2, 2E1 and 2D6 in human liver microsome (HLM).
