Reduced activities of thiamine-dependent enzymes in the brains and peripheral tissues of patients with Alzheimer's disease.
A report of cell loss in the nucleus basalis of Meynert in patients with Wernicke-Korsakoff disease prompted the examination of thiamine pyrophosphate (TPP)-dependent enzymes in the brain andExpand

Glial glutamate dehydrogenase: Ultrastructural localization and regional distribution in relation to the mitochondrial enzyme, cytochrome oxidase
Glutamate dehydrogenase (GDH) is primarily a mitochondrial enzyme involved in the metabolism of glutamate. We have recently shown by light microscopic immunocytochemistry that, withinExpand

Regional distribution of astrocytes with intense immunoreactivity for glutamate dehydrogenase in rat brain: implications for neuron-glia interactions in glutamate transmission
The principally mitochondrial enzyme glutamate dehydrogenase (GDH) exhibited low-intensity, uniform immunoreactivity in neurons and intense heterogeneous labeling of glial cells of rat brain.Expand

Polyglutamine Domains Are Substrates of Tissue Transglutaminase: Does Transglutaminase Play a Role in Expanded CAG/Poly‐Q Neurodegenerative Diseases?
Abstract: Huntington's disease and six other neurodegenerative diseases are associated with abnormal gene products containing expanded polyglutamine (poly‐Q; Qn) domains (n ≥ 40). In the presentExpand

The Pyruvate Dehydrogenase Complex Is Partially Inactivated During Early Recirculation Following Short‐Term Forebrain Ischemia in Rats
Abstract: The mechanisms of selective neuronal loss after short‐term global ischemia remain undefined, but processes including increased proteolytic activity, impaired protein synthesis, andExpand

The alpha-ketoglutarate dehydrogenase complex in neurodegeneration.
Altered energy metabolism is characteristic of many neurodegenerative disorders. Reductions in the key mitochondrial enzyme complex, the alpha-ketoglutarate dehydrogenase complex (KGDHC), occur in aExpand

Light microscopic immunocytochemical localization of pyruvate dehydrogenase complex in rat brain: topographical distribution and relation to cholinergic and catecholaminergic nuclei
Pyruvate dehydrogenase complex (PDHC; EC, EC and EC includes 3 catalytically active mitochondrial enzymes involved in the formation of cellular energy through theExpand

Pathogenesis of Inclusion Bodies in (CAG)n/Qn‐Expansion Diseases with Special Reference to the Role of Tissue Transglutaminase and to Selective Vulnerability
Abstract : At least eight neurodegenerative diseases, including Huntington disease, are caused by expansions in (CAG)n repeats in the affected gene and by an increase in the size of the correspondingExpand

Distribution of the α‐ketoglutarate dehydrogenase complex in rat brain
The α‐ketoglutarate dehydrogenase complex (KGDHC) is a key enzyme in mitochondrial oxidation that appears critical to neurodegenerative diseases. Its activity in the brain declines inExpand

Zn2+ inhibits alpha-ketoglutarate-stimulated mitochondrial respiration and the isolated alpha-ketoglutarate dehydrogenase complex.
Intracellular free Zn(2+) is elevated in a variety of pathological conditions, including ischemia-reperfusion injury and Alzheimer's disease. Impairment of mitochondrial respiration is alsoExpand
