1 SIN-1(3-morpholino-sydnonimine), which can lead the simultaneous generation of superoxide anion and nitric oxide, and then form the highly reactive species ONOO(-), induced dose-dependent inhibition in amplitudes of both mEPSCs and sEPSCs. onoo MAPK associated protein 1 Homo sapiens
2 The SIN-1 action on mEPSC amplitude was completely blocked by U0126, a selective MEK inhibitor, suggesting that MEK contributed to the action of ONOO(-) on mEPSCs. onoo MAPK associated protein 1 Homo sapiens
3 SIN-1 inhibited the frequency of sEPSCs but had no effect on mEPSC frequency, which suggested a presynaptic action potential-dependent the action of ONOO(-) at CA1 pyramidal neuron synapses. onoo MAPK associated protein 1 Homo sapiens
