Abstract

Using galactose instead of glucose in the culture medium of hepatoma cell lines, such as HepG2 cells, has been utilized for a decade to unmask the mitochondrial liability of chemical compounds. A modified glucose-galactose assay on HepG2 cells, reducing the experimental period for screening of mitochondrial toxicity to 2 to 4 hr, has been previously reported. HepaRG cells are one of the few cell lines that retain some of the important characteristics of human hepatocytes, offering advantages of working with a cell line, therefore, are considered an alternative for HepG2 cells in drug toxicity screening. A method is described here using HepaRG cells in an acute metabolic switch assay utilizing specific glucose/galactose media, a combined ATP-protein-LDH assay measuring three endpoints from one 96-well plate, and a criteria to label a compound as a mitochondrial toxin. © 2019 by John Wiley & Sons, Inc.

使用葡萄糖/半乳糖培养基检测HepaRG细胞线粒体毒性的急性代谢开关试验
在肝癌细胞系(如HepG2细胞)的培养基中使用半乳糖代替葡萄糖,已经使用了十年,以揭示化学化合物的线粒体倾向。先前有报道称,在HepG2细胞上进行了一种改进的葡萄糖-半乳糖试验,将线粒体毒性筛选的实验时间缩短至2至4小时。HepaRG细胞是少数保留人类肝细胞一些重要特征的细胞系之一,具有与细胞系一起工作的优势,因此被认为是HepG2细胞在药物毒性筛选中的替代品。本文描述了一种方法,使用HepaRG细胞进行急性代谢开关试验,利用特定的葡萄糖/半乳糖培养基,结合atp蛋白- ldh试验,测量一个96孔板的三个端点,以及将化合物标记为线粒体毒素的标准。©2019 by John Wiley &儿子,Inc。
