A yeast TDP-43 proteinopathy model: Exploring the molecular determinants of TDP-43 aggregation and cellular toxicity
Open accessAbstract
Protein misfolding is intimately associated with devastating human neurodegenerative diseases, including Alzheimer's, Huntington's, and Parkinson's. Although disparate in their pathophysiology, many of these disorders share a common theme, manifested in the accumulation of insoluble protein aggregates in the brain. Recently, the major disease protein found in the pathological inclusions of two of these diseases, amyotrophic lateral sclerosis (ALS) and frontal temporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U), was identified as the 43-kDa TAR–DNA-binding protein (TDP-43), providing a molecular link between them. TDP-43 is a ubiquitously expressed nuclear protein that undergoes a pathological conversion to an aggregated cytoplasmic localization in affected regions of the nervous system. Whether TDP-43 itself can convey toxicity and whether its abnormal aggregation is a cause or consequence of pathogenesis remain unknown. We report a yeast model to define mechanisms governing TDP-43 subcellular localization and aggregation. Remarkably, this simple model recapitulates several salient features of human TDP-43 proteinopathies, including conversion from nuclear localization to cytoplasmic aggregation. We establish a connection between this aggregation and toxicity. The pathological features of TDP-43 are distinct from those of yeast models of other protein-misfolding diseases, such as polyglutamine. This suggests that the yeast model reveals specific aspects of the underlying biology of the disease protein rather than general cellular stresses associated with accumulating misfolded proteins. This work provides a mechanistic framework for investigating the toxicity of TDP-43 aggregation relevant to human disease and establishes a manipulable, high-throughput model for discovering potential therapeutic strategies.

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.
