Coupling of Inositol Phospholipid Metabolism with Excitatory Amino Acid Recognition Sites in Rat Hippocampus
Abstract
Abstract: Ibotenate, a rigid structural analogue of glutamate, markedly enhances the hydrolysis of membrane inositol phospholipids, as reflected by the stimulation of [3 H]inositol monophosphate formation in rat hippocampal slices prelabeled with [3 H]inositol and treated with Li+. Quisqualate, homocysteate, l‐glutamate, and l‐aspartate also induce a significant (albeit weaker) increase in [3 H]inositol monophosphate formation, whereas N‐methyl‐d‐aspartate, kainate, quinolinate, and N‐acetylaspartylglutamate are inactive. The increase in [3 H]inositol monophosphate formation elicited by the above‐mentioned excitatory amino acids is potently and selectively antagonized by dl‐2‐amino‐4‐phosphonobutyric acid, a dicarboxylic amino acid receptor antagonist. These results suggest that, in the hippocampus, a class of dicarboxylic amino acid recognition sites is coupled with phospholipase C, the enzyme that catalyzes the hydrolysis of membrane inositol phospholipids.

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.
