Figure 5From: Cytosolic phospholipase A2alpha amplifies early cyclooxygenase-2 expression, oxidative stress and MAP kinase phosphorylation after cerebral ischemia in miceConcentration of cortical PGE 2 following MCAO and reperfusion is dependent on cPLA 2 α. PGE2 was measured in cortical homogenate from the ipsilateral and contralateral hemispheres after A: 2 hours MCAO or sham operation and B: 2 hours of MCAO and 6 hours reperfusion. Results are expressed as normalized for each lipid extraction and assay. * P < 0.05; ** P < 0.01 n = 3 - 4 each condition.Back to article page
