Abstract/Description:
Ischemic stroke is one of the leading causes of human death worldwide. It occurs due to high susceptibility of neurons to anoxia and reoxygenation. Unlike mammals, invertebrate Drosophila melanogaster withstands low oxygen levels without showing pathology. In the present study, Drosophila Schneider (S2) cells were employed to investigate the role of the cGMP-dependent Protein Kinase (PKG) signaling pathway in Drosophila anoxia-tolerance in vitro. This was accomplished by subjecting cells to chemical anoxia and oxidative stress concurrently with treatments by pharmacological agents affecting specific targets of the PKG pathway and assessing cytotoxicity. In this study, activation of the PKG pathway protected S2 cells from the aforementioned stresses. The results of this study may lead to a better understanding of fruit fly’s innate anoxia-tolerance strategies. Consequently, this knowledge may be used to identify potential therapeutic targets to prevent detrimental neurological effects of an ischemic stroke in humans.
