Reverse transcription‑PCR analysis of identified proteins in retinoic acid treated animals with middle cerebral artery occlusion animal model. Image of reverse transcription-PCR products (A) of ubiquitin carboxy-terminal hydrolase L1, ubiquitin thioesterase OTUB1, and proteasome subunit alpha types 1 and 3 in the cerebral cortex from vehicle + middle cerebral artery occlusion (MCAO), retinoic acid (RA) + MCAO, vehicle + sham, and RA + sham animals. The band intensity (B and C) of the reverse transcription-PCR product is expressed as a ratio of β-actin product intensity. Data (n = 5 per group) are represented as the mean ± S.E.M. *p < 0.05, **p < 0.01
