Abstract

The sympathetic nerve cell line PC-12 is killed by glutamate in a concentration-dependent manner. Although glycine and the deletion of magnesium weakly potentiate glutamate toxicity and PC-12 cells express N-methyl-D-aspartate-receptor mRNA, most toxicity is mediated by means of a mechanism independent of typical N-methyl-D-aspartate receptors. Glutamate toxicity is, however, greatly enhanced by prior exposure to nerve growth factor or basic fibroblast growth factor. Glutamate killing is blocked by epidermal growth factor and, to a lesser extent, by vitamin E. These observations show that synergistic interactions between growth factors and excitotoxic amino acids may play critical roles in the developing nervous system and that antioxidants attenuate this toxicity.

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.
