Abstract

The unfolded protein response (UPR) is induced at symptom onset and disease end stage in rodent models of familial amyotrophic lateral sclerosis (ALS) that express superoxide dismutase (SOD1) mutations. However, ninety percent of human ALS is sporadic and mutations in SOD1 account for only 2% of total ALS. Here we show that a full UPR, including induction of stress sensor kinases, chaperones and apoptotic mediators, is also present in spinal cords of human patients with sporadic disease. Furthermore, the UPR chaperone protein disulphide isomerase (PDI) was present in CSF and was aggregated and widely distributed throughout the motor neurons of these patients. We also show up-regulation of UPR prior to the onset of symptoms in SOD1 rodents, implying an active role in disease. This study offers new insights into pathogenesis, placing ER stress onto a generic pathophysiology for ALS.

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.
