The purpose of this study was establishing the basic energetic parameters of amoeba Acanthamoeba castellanii mitochondria respiring with malate and their response to oxidative stress caused by hydrogen peroxide in the presence of Fe2+ ions. It appeared that, contrary to a previous report (Trocha LK, Stobienia O (2007) Acta Biochim Polon 54: 797), H2O2-treated mitochondria of A. castellanii did not...
The purpose of this study was to examine the effects of oxidative stress caused by hydroperoxide (H2O2) in the presence of iron ions (Fe2+) on mitochondria of the amoeba Acanthamoeba castellanii. We used isolated mitochondria of A. castellanii and exposed them to four levels of H2O2 concentration: 0.5, 5, 15, and 25 mM. We measured basic energetics of mitochondria: oxygen consumption in phosphorylation...
