Abstract

The tetracycline antibiotic minocycline beneficially affects neuronal functioning and also inhibits the enzyme 5-lipoxygenase (5-LOX). We hypothesized that similar to 5-LOX inhibitors, minocycline may increase phosphorylation and membrane insertion of the glutamate receptor GluR1. The experiments were performed in primary cultures of mouse striatal neurons and in the prefrontal cortex and striatum of minocycline-treated mice. In vitro, low micromolar minocycline concentrations increased GluR1 phosphorylation at Ser845 and Ser831 and increased the surface content of GluR1. Minocycline also increased GluR1 phosphorylation in vivo. Increased GluR1 phosphorylation and minocycline treatment have been associated with antidepressant and memory-enhancing activities. Direct consequences of minocycline-increased GluR1 phosphorylation are yet to be established.

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.
