NADH oxidase activity of mitochondrial apoptosis-inducing factor.
Apoptosis-inducing factor (AIF) is a mitochondrial flavoprotein, which translocates to the nucleus during apoptosis and causes chromatin condensation and large scale DNA fragmentation. Here we report the biochemical characterization of AIF's redox activity. Natural AIF purified from mitochondria and recombinant AIF purified from bacteria (AIFDelta1-120) exhibit NADH oxidase activity, whereas su...
متن کاملApoptosis-inducing factor modulates mitochondrial oxidant stress in acetaminophen hepatotoxicity.
Acetaminophen (APAP) overdose causes liver injury in humans and mice. DNA fragmentation is a hallmark of APAP-induced cell death, and nuclear translocation of apoptosis-inducing factor (AIF) correlates with DNA fragmentation after APAP overdose. To test the hypothesis that AIF may be a critical mediator of APAP-induced cell death, fasted male AIF-deficient Harlequin (Hq) mice and respective wil...
متن کاملRole of apoptosis-inducing factor, proline dehydrogenase, and NADPH oxidase in apoptosis and oxidative stress.
Flavoproteins catalyze a variety of reactions utilizing flavin mononucleotide or flavin adenine dinucleotide as cofactors. The oxidoreductase properties of flavoenzymes implicate them in redox homeostasis, oxidative stress, and various cellular processes, including programmed cell death. Here we explore three critical flavoproteins involved in apoptosis and redox signaling, ie, apoptosis-induci...
متن کاملApoptosis-inducing factor
Although the seminal paper by Kerr, Wyllie and Currie (Kerr et al., 1972), who coined the word ‘apoptosis’, stated that only nuclei but not cytoplasmic organelles would undergo major modifications in the dying cell, recent evidence suggests that no cellular compartment is spared (Ferri and Kroemer, 2001). Mitochondria are particularly affected early during the apoptotic process, and they are no...
متن کاملHydatid Cyst Killing Mechanism of Ziziphora tenuior by Inducing Apoptosis via Mitochondrial Intrinsic Pathway
Background and objectives: Ziziphora tenuior is considered as an appropriate protoscolicidal agent yet the mechanism of such effect is not known so far. The aim of this study was to evaluate the apoptotic effect of Z. tenuior extract on protoscolices of hydatid cyst. Methods: Protoscolices were collected aseptically and the Bradford test was e...
