Mitochondrial viability in mouse and human postmortem brain.
Neuronal function in the brain requires energy in the form of ATP, and mitochondria are canonically associated with ATP production in neurons. The electrochemical gradient, which underlies the mitochondrial transmembrane potential (DeltaPsi(mem)), is harnessed for ATP generation. Here we show that DeltaPsi(mem) and ATP-production can be engaged in mitochondria isolated from human brains up to 8...
متن کاملMitochondrial dysfunction in mouse trisomy 16 brain.
Mitochondrial function in the brain of mouse trisomy 16, an animal model of Down syndrome with accelerated neuron death, was studied in isolated cortex mitochondria. Using an oxygen-sensitive Clarke electrode, a selective 16% decrease in respiration was detected with the Complex I substrates malate and glutamate but not with the Complex II substrate succinate. Western blotting revealed a 20% de...
متن کاملConstitutive expression and functional characterization of mitochondrial glutaredoxin (Grx2) in mouse and human brain.
Oxidative stress and mitochondrial dysfunction caused by loss of complex I activity are presumed to be primary events leading to neurodegeneration in Parkinson's disease. Mitochondrial glutaredoxin (Grx2), a glutathione-dependent thiol disulfide oxidoreductase helps maintain redox homeostasis in the mitochondria. We therefore, examined the constitutive expression of Grx2 in brain and its role i...
متن کاملFelbamate Increases [H]Glycine Binding in Rat Brain and Sections of Human Postmortem Brain
The anticonvulsant compound felbamate (2-phenyl-1,3-propanediol dicarbamate; FBM) appears to inhibit the function of the N-methyl-D-aspartate (NMDA) receptor complex through an interaction with the strychnine-insensitive glycine recognition site. Since we have demonstrated previously that FBM inhibits the binding of [H]5,7-dichlorokynurenic acid (DCKA), a competitive antagonist at the glycine s...
