... ATPases, resulting in a gradual loss of ion homeostasis during anoxia. This is particularly problematic if extracellular K + concentration rises ( Rodgers et al., 2010 ; Campbell et al., 2018 ), as a disrupted transmembrane [K + ] gradient leads to cell membrane depolarization, which can initiate...

... larvae, adults maintain low but survivable ATP levels for long durations in anoxia. Summary: Adult Drosophila melanogaster survive anoxic exposure by maintaining ATP at 3% of normal and tolerating a drastic disruption of ion balance. ATP Ion homeostasis Extracellular potassium D...

... better able to defend V m whilst exposed to high extracellular [K + ]. Together these results demonstrate a mechanism of cold acclimation in locusts that improves survival after cold stress: increased cold tolerance is accomplished by preservation of V m through maintenance of ion homeostasis...

... majority of mammals are unable to survive prolonged periods of hypothermia or O 2 deprivation owing to irreversible membrane damage and loss of cellular ion homeostasis in vital organs such as the brain and heart. However, numerous hibernating endotherms, neonatal and diving mammals as well as many...
