Cardiac and skeletal muscle critically depend on mitochondrial energy metabolism for their normal function. Recently, we showed that apoptosis-inducing factor (AIF), a mitochondrial protein implicated in programmed cell death, plays a role in mitochondrial respiration. However, the in vivo consequences of AIF-regulated mitochondrial respiration resulting from a loss-of-function mutation in Aif ...
We demonstrate the role of p53-mediated caspase-2 activation in the mitochondrial release of apoptosis-inducing factor (AIF) in cisplatin-treated renal tubular epithelial cells. Gene silencing of AIF with its small interfering RNA (siRNA) suppressed cisplatin-induced AIF expression and provided a marked protection against cell death. Subcellular fractionation and immunofluorescence studies reve...
Photodynamic therapy (PDT) with endogenous protoporphyrin IX derived from 5-aminolevulinic acid or its derivatives has been established for treatments of several premalignancies and malignancies; however, the mechanism of the modality is not fully elucidated. The mitochondrial permeability transition pore consists mainly of the mitochondrial outer membrane voltage-dependent anion channel and th...
Inhibition of poly(ADP-ribose) polymerase (PARP) has been proposed to have a neuroprotective effect on hippocampal neurons in animal models of epilepsy. However, the mechanisms of PARP-mediated epileptic neuron apoptosis in vitro are still not thoroughly understood. Therefore, we investigated the effect of PARP inhibition and the underlying mechanisms in the hippocampal neuronal culture model o...
Developing polyamine conjugates having the potential of transporting naphthalimide selectively into tumor cells is attractive. However, the evaluation of their cytotoxic mechanism has not been comprehensive. This study focused on the effects of mononaphthalimide spermidine (MNISpd) conjugate on apoptosis induction and the relationship between MNISpd-induced apoptosis and reactive oxygen species...
Cerebral ischemia/reperfusion (I/R) injury could cause neural apoptosis that involved the signaling cascades. Cytochrome c release from the mitochondria and the followed activation of caspase 9 and caspase 3 are the important steps. Now, a new mitochondrial protein, apoptosis-inducing factor (AIF), has been shown to have relationship with the caspase-independent apoptotic pathway. In this study...
Arsenic trioxide (As(2)O(3)) has been used successfully in the treatment of acute promyelocytic leukemia. However, effects of As(2)O(3) in normal peripheral blood T cells have not been studied in detail. The purpose of this study was to investigate whether As(2)O(3) would induce apoptosis in normal T cells and therefore may have immunosuppressive side effects. Apoptosis was measured by terminal...
