Abstract

Cardiolipin peroxidation plays a critical role in mitochondrial cytochrome c release and subsequent apoptotic process. Mitochondrial pore transition (MPT) is considered as an important step in this process. In this work, the effect of peroxidized cardiolipin on MPT induction and cytochrome c release in rat heart mitochondria was investigated. Treatment of mitochondria with micromolar concentrations of cardiolipin hydroperoxide (CLOOH) resulted in a dose‐dependent matrix swelling, Δ Ψ collapse, release of preaccumulated Ca 2+ and release of cytochrome c . All these events were inhibited by cyclosporin A and bongkrekic acid, indicating that peroxidized cardiolipin behaves as an inducer of MPT. Ca 2+ accumulation by mitochondria was required for this effect. ANT (ADP/ATP translocator) appears to be involved in the CLOOH‐dependent MPT induction, as suggested by the modulation by ligands and inhibitors of adenine nucleotide translocator (ANT). Together, these results indicate that peroxidized cardiolipin lowers the threshold of Ca 2+ for MPT induction and cytochrome c release. This synergistic effect of Ca 2+ and peroxidized cardiolipin on MPT induction and cytochrome c release in mitochondria, might be important in regulating the initial phase of apoptosis and also may have important implications in those physiopathological situations, characterized by both Ca 2+ and peroxidized cardiolipin accumulation in mitochondria, such as aging, ischemia/reperfusion and other degenerative diseases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
