Group III metabotropic glutamate receptors in rat cultured calvarial osteoblasts

Abstract

Reverse transcription polymerase chain reaction revealed expression of mRNAs for particular receptors for the central neurotransmitter l-glutamic acid (Glu) in primary cultures of rat calvarial osteoblastic cells under premature to mature states according to the duration of days in vitro. These included metabotropic Glu receptors (mGluR) such as mGluR4 and mGluR8, in addition to several ionotropic Glu receptor subunits including NR1 and NR2D. Expression of mRNAs was not detected with other mGluR and NR2A-C subunits irrespective of the maturity of cultured cells. The agonist for group III mGluR L-(+)-2-amino-4-phosphonobutyric acid significantly inhibited the forskolin-induced accumulation of cAMP in premature osteoblasts, which occurred in a manner sensitive to prevention by the group III mGluR antagonist (RS)-alpha-cyclopropyl-4-phosphonophenylglycine. These results suggest that Glu may at least in part play a role in mechanisms associated with cellular proliferation and/or differentiation through group III mGluR functionally expressed in rat calvarial osteoblastic cells.

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.
