Abstract Mitochondrial transfer occurs both in stroke (central nervous system) and inflammatory pain (peripheral nerves). However, its role glioblastoma (GBM) remains poorly understood. We hypothesized that mitochondrial from non-malignant to GBM cells supports tumor metabolism growth. Using transgenic mice expressing fluorophore-tagged mitochondria, we found ~50% of orthotopically-implanted mo...

Mitochondria are key contributors to many forms of cell death including those resulting from neonatal hypoxic-ischemic brain injury. Mice have become increasingly popular in studies of brain injury, but there are few reports evaluating mitochondrial isolation procedures for the neonatal mouse brain. Using evaluation of respiratory activity, marker enzymes, western blotting and electron microsco...

We have studied the effects of bilirubin on respiration, respiratory control, oxidative phosphorylation, and swelling of mitochondria from rat liver, bovine heart, and brain of chick, rabbit, and monkey. Low (<4!0 PM) concentrations of bilirubin increase and high concentrations (>50 PM) decrease the respiration of liver or heart mitochondria. This biphasic effect is not observed in brain mitoch...

Poly(ADP-ribose) polymerase-1-dependent cell death (known as parthanatos) plays a pivotal role in many clinically important events including ischaemia/reperfusion injury and glutamate excitotoxicity. A recent study by us has shown that uncleaved AIF (apoptosis-inducing factor), but not calpain-hydrolysed truncated-AIF, was rapidly released from the mitochondria during parthanatos, implicating a...

Brain function declines with age and is associated with diminishing mitochondrial integrity. The neuronal mitochondrial ultrastructural changes of young (4 months) and old (21 months) F344 rats supplemented with two mitochondrial metabolites, acetyl-L-carnitine (ALCAR, 0.2%[wt/vol] in the drinking water) and R-alpha-lipoic acid (LA, 0.1%[wt/wt] in the chow), were analysed using qualitative and ...

Mitochondrial dysfunction contributes to the pathophysiology of both acute and chronic neurodegenerative disorders. Quantification of mitochondrial bioenergetic properties generally requires the use of isolated brain mitochondria. However, the involvement of neuronal mitochondrial dysfunction in these disorders is limited by the lack of markers, and therefore isolation procedures, that distingu...

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...
