Abstract：
:The effect of N-methyl-D-aspartate (NMDA) receptor antagonists on cell viability was studied in rat primary cortical cells. NMDA antagonists [MK-801 and 2-amino-5-phosphonovalerate (APV)] induced cell shrinkage, nuclear condensation or fragmentation, and internucleosomal DNA fragmentation. Treatment of cells with MK-801 (an NMDA antagonist) for 1-2 days induced apoptotic cell death in a dose-dependent manner (1 nM to 10 microM). NMDA (25 microM), however, inhibited the MK-801 (0.1 microM)-induced apoptotic cell death. MK-801 and APV decreased the concentration of intracellular calcium ion. Activation of caspase-3 was accompanied by MK-801-induced cell death in a dose-dependent manner, and an inhibitor of caspase-3 reduced the cell death. Further, cycloheximide (0.2 microg/ml) completely protected the cells from MK-801-induced apoptotic cell death and caspase-3 activation. Insulin-like growth factor I completely attenuated MK-801-induced apoptotic cell death and caspase-3 activation. These results demonstrated that the moderate NMDA receptor activation is probably involved in the survival signal of the neuron.
