Outline of Final Research Achievements

There are few reports regarding toxicity and enzyme activity associated with drug-metabolizing enzyme accumulated by disruption of its protein degradation system. We have clarified that acetaminophen led to inhibit CYP3A protein degradation and accordingly induced its enzyme activity using 3-dimensional hepatocyte culture. The results could contribute formation of the reactive metabolite by CYP3A, which is known to induce hepatotoxicity. Acetaminophen analog also showed inhibitory effects on CYP3A degradation in 3-dimensional culture. These findings could lead to clarify the detailed mechanism.
