The proteasome in brain aging

Keller, J·2002·Ageing Research Reviews

Abstract

The proteasome is a large intracellular protease, present in all cells of the central nervous system (CNS), that is responsible for the majority of intracellular protein degradation. In particular, the proteasome is responsible for the degradation of most oxidized, aggregated, and misfolded proteins. The importance of proteasome activity to neuronal homeostasis is highlighted by previous studies demonstrating that proteasome inhibition alone is sufficient to induce neuron death in vitro. Recent studies indicate that alterations in proteasome activity may occur during, and possibly contribute to, the aging process. These data raise the possibility that alterations in the proteasome proteolytic pathway may contribute to the elevations in protein oxidation, protein aggregation, and neurodegeneration evident in the aging CNS. The focus of this review is to describe what is currently known about the proteasome in the CNS, describe established age-related alterations in proteasome biology, and to discuss how such alterations in proteasome biology may ultimately contribute to the aging of the CNS.

  • Evidence of impaired UPS in the aging brain includes age-dependent accumulation of polyubiquitinated proteins in neurons and brain-region-specific reduction of proteasome activity in hippocampus and cerebral cortex.

    “Similar to age-dependent reduction of autophagy, evidence of impaired UPS in the aging brain arises from studies showing age-dependent accumulation of polyubiquitinated proteins in neurons and a brain region-specific reduction of age-dependent proteasome activity in the hippocampus and cerebral cortex (Keller et al., 2002; Mattson and Arumugam, 2018).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
