Standardized hypoxia-reoxygenation protocol to assess posthypoxic neurobehavioral impairments and molecular mechanisms in Drosophila melanogaster

Hypoxia plays a pivotal role in the pathogenesis of major causes of mortality such as cerebral ischemia. Here, we present a standardized protocol for the induction of global hypoxia and reoxygenation in Drosophila melanogaster, with details on subsequent analysis of mortality, neurobehavioral impairments, and molecular mechanisms. This protocol emphasizes the importance of controlling and monitoring specific environmental parameters to ensure reproducible results. It also highlights profound differences that can arise from variations in the age and genotype of the flies. For complete details on the use and execution of this protocol, please refer to Habib et al. (2021).
