Identification of differentially expressed proteins by retinoic acid in middle cerebral artery occlusion animal model. Images of protein spots of ubiquitin carboxy-terminal hydrolase L1, ubiquitin thioesterase OTUB1 (A), proteasome subunit alpha types 1, proteasome subunit alpha types 3 (B), and hypoxanthine phosphoribosyltransferase (C) in the cerebral cortex from vehicle + middle cerebral artery occlusion (MCAO), retinoic acid (RA) + MCAO, vehicle + sham, and RA + sham animals. Each square indicates protein spots. Intensities of protein spots (D–F) were analyzed with Image J software and normalized as a ratio of intensity of each group to that of vehicle + sham group. Data (n = 5 per group) are represented as the mean ± S.E.M. *p < 0.05, **p < 0.01
