Schizophrenia Induces Oxidative Stress and Cytochrome C Release in Isolated Rat Brain Mitochondria: a Possible Pathway for Induction of Apoptosis and Neurodegeneration

schizophrenia induces oxidative stress and cytochrome c release in isolated rat brain mitochondria: a possible pathway for induction of apoptosis and neurodegeneration

schizophrenia is a chronic and often debilitating illness which affects about 1% of the world population. some reagents have been used to simulate schizophrenic disorders in laboratory animals, such as amphetamine and ketamine. previous studies have suggested that reactive oxygen species (ros) production, reduced levels of atp, mitochondrial dysfunction and apoptosis are involved in the pathoph...

depleted uranium induces disruption of energy hemostasis and oxidative stress in isolated rat brain mitochondria

Bax directly induces release of cytochrome c from isolated mitochondria.

Bax is a pro-apoptotic member of the Bcl-2 protein family that resides in the outer mitochondrial membrane. It is controversial whether Bax promotes cell death directly through its putative function as a channel protein versus indirectly by inhibiting cellular regulators of the cell death proteases (caspases). We show here that addition of submicromolar amounts of recombinant Bax protein to iso...

Ceramide induces cytochrome c release from isolated mitochondria.

This chapter addresses the role of mitochondria in apoptosis. Emphasis is put on the recently observed influence of ceramides on mitochondrial functions. We report here that N-acetylsphingosine (C2-ceramide), N-hexanoylsphingosine (C6-ceramide) and, to a much lesser extent, C2-dihydroceramide, induce cytochrome c (cyt c) release from isolated rat liver mitochondria. Ceramide-induced cyt c relea...
