Abstract

In all animal species, oxygen consumption is a key process that is partially impaired in a large number of pathological situations and thus provides informative details on the physiopathology of the disease. In this study, we describe a simple and affordable method to precisely measure oxygen consumption in living zebrafish larvae using a spectrofluorometer and the MitoXpress Xtra Oxygen Consumption Assay. In addition, we used zebrafish larvae treated with mitochondrial respiratory chain inhibitors, antimycin A or rotenone, to verify that our method enables precise and reliable measurements of oxygen consumption.

摘要

在所有动物物种中,氧气消耗是一个关键过程,在大量病理情况下会部分受损,因此为疾病的病理生理学提供了有价值的信息。在这项研究中,我们描述了一种使用分光荧光计和 MitoXpress Xtra 氧消耗测定试剂盒精确测量活体斑马鱼幼鱼氧气消耗的简单且经济的方法。此外,我们还使用线粒体呼吸链抑制剂,如antimycin A 或鱼藤酮处理斑马鱼幼虫,以验证我们的方法能够精确可靠地测量氧气消耗。
