Possible mechanisms for procaspase-3 denitrosylation and activation. Cerebral I/R actives KA receptor subunit GluR6 to induce upregulation of FasL expression, which bind more Fas receptors leading to activation of Trx-TrxR system. Procaspase-3 is then denitrosylated and subsequently activated leading to neuronal apoptosis
