Abstract
We have investigated the expression of neuropeptide Y (NPY) in C6 glioma cells after the glutamatergic stimulation by the in situ RT-PCR and immunocytochemical techniques. The expression of NPY mRNA correlated well with immunocytological findings in each series of experiments. NPY protein expression was enhanced by glutamate (1, 10, 50, 100 μM, and 1 mM) dose-dependently, and its expression was slightly increased by N-methyl-d-aspartate (NMDA; 1, 10, 100, 500 μM, and 1 mM) and kainic acid (1, 10, 100, 300 μM, and 1 mM). We pretreated the cells with dopamine, haloperidol, pentylenetetrazol, and muscimol before each stimulation. The pentylenetetrazol and muscimol did not significantly alter the patterns of NPY expression induced by the glutamatergic stimulation. On the other hand, the dopamine and haloperidol pretreatment significantly elevated the levels of NPY expression that were induced by NMDA and kainic acid. Our results indicate that NPY release is closely related to glutamatergic stimulation, and it could be dynamically mediated by GABAergic and dopaminergic costimulation.
