Abstract

Significance: Cocaine is one of the most abused drugs in modern society, with overdoses that are frequently lethal. Molecular mechanisms underlying its toxic actions have been obscure. The present study demonstrates that cocaine’s cellular toxicity involves a signaling cascade that utilizes the gasotransmitter nitric oxide, which leads to autophagy, a cellular modification that can cause cell death. Thus, manipulations that impair nitric oxide signaling and autophagy diminish cytotoxic actions of cocaine. By contrast, alterations of apoptosis and other nonautophagic modes of cell death are ineffective. Therapies directed toward the autophagic process may be beneficial in treating cocaine neurotoxicity.

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.
