本研究探讨了乙醇和烯丙醇对小鼠原代肝细胞的影响。乙醇处理未观察到细胞毒性,但烯丙醇处理对细胞的毒性更大。细胞色素P450 2E1(CYP2E1),I相酶的表达进行了检查响应乙醇和烯丙醇。两种外源性物质在蛋白质水平诱导CYP2E1高达1.5 - 1.5倍。还测定了胰岛素对CYP2E1表达的影响。胰岛素被认为是原代肝细胞的必需激素,显示出降低CYP2E1蛋白水平,并且不影响细胞活力。CYP2E1诱导的这些结果表明,原代小鼠肝细胞,当使用乙醇和烯丙醇作为底物和在无胰岛素的培养基中,为研究CYP2E1在异生物质代谢和毒性中的作用提供了合适的系统。
In this study, the effects of ethanol and allyl alcohol on primary mouse hepatocytes were investigated. No cytotoxicity was observed by ethanol treatments, but more toxicity to cells was found in the response to allyl alcohol treatment. The expression of cytochrome P450 2E1 (CYP2E1), phase I enzyme was examined in response to ethanol and allyl alcohol. Both xenobiotics induced CYP2E1 up to 1.5∼5 fold at the protein level. The effects of insulin on CYP2E1 expression were also measured. Insulin, which has been regarded as an essential hormone for primary hepatocytes, was shown to decrease the level of CYP2E1 protein, and did not affect cell viability. These results on CYP2E1 induction demonstrate that primary mouse hepatocytes, when using ethanol and allyl alcohol as substrates and in insulin-free medium, provide a suitable system for the studies of the role of CYP2E1 in xenobiotic metabolism and toxicity.
