Mitochondrial dysfunction is an early event in high-NaCl-induced apoptosis of mIMCD3 cells.
Raising osmolality to 700 mosmol/kgH(2)O by the addition of NaCl rapidly kills most murine inner renal medullary collecting duct cells (mIMCD3), but they survive at 500 mosmol/kgH(2)O. At 300 and 500 mosmol/kgH(2)O, NADH autofluorescence is present in a mitochondria-associated, punctate perinuclear pattern. Within 45 s to 30 min at 700 mosmol/kgH(2)O, the autofluorescence spreads diffusely thro...
متن کاملOsthole Attenuates Doxorubicin-Induced Apoptosis in PC12 Cells through Inhibition of Mitochondrial Dysfunction and ROS Production
Doxorubicin (DOX) is a potent, broad-spectrum chemotherapeutic drug used for treatment of several types of cancers. Despite its effectiveness, it has a wide range of toxic side effects, many of which most likely result from its inherent prooxidant activity. It has been reported that DOX has toxic effects on normal tissues, including brain tissue. In the current study, we investigated the protec...
متن کاملMitochondrial dysfunction in lyssavirus-induced apoptosis.
Lyssaviruses are highly neurotropic viruses associated with neuronal apoptosis. Previous observations have indicated that the matrix proteins (M) of some lyssaviruses induce strong neuronal apoptosis. However, the molecular mechanism(s) involved in this phenomenon is still unknown. We show that for Mokola virus (MOK), a lyssavirus of low pathogenicity, the M (M-MOK) targets mitochondria, disrup...
متن کاملCumulative and irreversible cardiac mitochondrial dysfunction induced by doxorubicin.
Interference with mitochondrial calcium regulation is proposed to be a primary causative event in the mechanism of doxorubicin-induced cardiotoxicity. We previously reported disruption of mitochondrial calcium homeostasis after chronic doxorubicin administration (Solen et al. Toxicol. Appl. Pharmacol, 129: 214-222, 1994). The present study was designed to characterize the dose-dependent and cum...
