[Abstract]  Mammalian cells generate ATP by mitochondrial (oxidative phosphorylation) and non-mitochondrial (glycolysis) metabolism. Cancer cells are known to reprogram their metabolism using different strategies to meet energetic and anabolic needs (Koppenol et al., 2011; Zheng, 2012). Additionally, each cancer tissue has its own individual metabolic features. Mitochondria not only play a key role in energy metabolism but also in cell cycle regulation of cells. Therefore, mitochondria have emerged as a potential target for anticancer therapy since they are structurally and functionally ... [摘要]  哺乳动物细胞通过线粒体(氧化磷酸化)和非线粒体(糖酵解)代谢产生ATP。已知癌细胞使用不同的策略重新编程它们的代谢以满足能量和合成代谢需要(Koppenol等人,2011; Zheng,2012)。此外,每个癌症组织都有其自己的个体代谢特征。线粒体不仅在能量代谢中起关键作用,而且在细胞的细胞周期调控中也起关键作用。因此,线粒体作为抗癌治疗的潜在靶标已经出现,因为它们在结构和功能上与其非癌对应物不同(D'Souza等人,2011)。我们详细介绍了利用海马XF24细胞外通量分析仪(图1)测量活细胞中氧耗率(OCR)和细胞外酸化率(ECAR)测量的方案。 Seahorse XF24细胞外通量分析仪持续测量细胞上清液中的氧浓度和质子流量(Wu等人,2007)。这些测量结果在OCR和ECAR值中转换,并能够直接定量线粒体呼吸和糖酵解。有了这个协议,我们试图评估三种不同癌细胞系的基线粒体功能和线粒体应激反应细胞毒性测试先导化合物甲磺卡西林,以研究其作用机制。将细胞铺在XF24细胞培养板中并保持24小时。在分析之前,将培养基替换为无缓冲的DMEM pH7.4,然后使细胞在非代谢通量分析前使用Seahorse XF在非CO 2孵育器中平衡以允许精确测量Milli-pH单位改变。 ...
