Up to one thousand potential drugs or interventions have been developed to treat stroke, out of which ~160 have gone on to clinical trials. However, none of them has been successful. New insights into the molecular and cellular mechanisms of ischemia-induced injury are needed for discovering new therapeutic targets. Recently, Drosophila has been used to uncover new hypoxia-related genes. In this study, we describe an efficient and reliable assay with a sophisticated apparatus for studying the effects of oxygen deprivation on flies. Using this assay, wild-type flies were exposed to an anoxic environment for varying lengths of time, then the cumulative death rate and mobility recovery were systematically analyzed. We found that anoxia for over one hour caused lethality. The cumulative death rate on day 5 after anoxia was linearly and positively correlatedwith the duration of anoxia, and reached 50% when the duration was 2.5 h–3 h. We also found that the mobility recovery in normoxia was slow, as the climbing ability remained largely unchanged 4 h–6 h after 2.5-h of anoxia.We suggest that 2.5 h–3 h of anoxia and 4 h–6 h of recovery before mobility analysis are appropriate for future use of the anoxia assay. 关键词：HYPOXIA ANOXIA DROSOPHILA Mortality LOCOMOTOR activity
