We hypothesized that the interaction between health foods and drug metabolism was the cause of severe liver injury in these patients. Therefore, we studied changes in the activity of the drug-metabolizing enzyme, cytochrome P450 (CYP), using slimming health food extracts and elucidated the molecular mechanism of liver injury onset through hepatotoxicity evaluation. Methods: For cytotoxicity testing, health food extract samples were added to HepG2 cells derived from hepatic parenchymal cells and culture medium, and cell viability was calculated 48 h after culture. To evaluate CYP3A4 induction, 3-1-10 cells constructed with a reporter linked to CYP3A4 gene were used, and reporter activity was measured 48 h after culture. Results: In the chronological order of the slimming health food intake history of the patient, niacinamide and Gymnema sylvestre extracts strongly inhibited HepG2 cell viability. In contrast, dietary supplements A and Coleus forskohlii extract strongly induced CYP3A4 reporter activity. To confirm CYP3A4 induction in humans, humanized CYP3A/pregnane X receptor (PXR) mice were treated with forskolin. CYP3A4 mRNA expression levels were elevated 3.9 times compared to that of the control group (P < 0.05). Conclusion: Coleus forskohlii extract showed the strongest transcriptional activation of CYP3A4 gene. In a mouse model of human-type drug metabolism, forskolin induced CYP3A4 transcription. Thus, we concluded that CYP3A4 induction by Coleus forskohlii is one of the causes of crucial hepatocellular injury, which is a type of liver injury caused by the active metabolite of acetaminophen produced by CYP3A4.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tottori
