    Mitochondrial Complex I superoxide production is attenuated by uncoupling

  • Original language description

    We have shown, that uncoupling diminishes rotenone-induced H2O2 production also in state 3 and that 5-(N-ethyl-N-isopropyl) amiloride is a real inhibitor of Complex I Hplus pumping . This amiloride also prevented suppression by FCCP of rotenone-induced H2O2 production with Complex I and II substrates. Our data suggest that Complex I mitochondrial superoxide production can be attenuated by uncoupling, which means by acceleration of Complex I H+ pumping due to the respiratory control. However, when this acceleration is prevented by 5-(N-ethyl-N-isopropyl) amiloride inhibition, no attenuation of superoxide production takes place

    Produckce superoxidu na mitochondriálním komplexu I je snižována odpřažením

  • Czech description

    Ukázali jsme, že odpřažení snižuje rotenonem zvýšenou produkci H2O2 ve stavu 3 a že 5-(N-ethyl-N-isopropyl) amiloride inhibuje pumpování protonů na komplexu I dýchacího řetězce. Tento amilorid také zabránil atenuujícímu efektu odpřahovače. Data svědčí pro snižování produkce superocidu na komplexu I při odpřažení tedy o akcelerování respirace, které lze zabránit inhibicí amiloridem. To ale není doprovázené snižováním produkce superoxidu
