Multiple protein and mRNA expression correlations in the rat cerebral cortex after ischemic injury and repair due to buchang naoxintong jiaonang (BNJ) intervention

Publication date: May 2020Source: Biomedicine & Pharmacotherapy, Volume 125Author(s): Xin Liu, Qing Wang, Yiran Cui, Muhammad Hussain, Hongjun Yang, Xianyu LiAbstractStroke is the one of the most common causes of death worldwide. Systematic description and characterization of the types of stroke and the effects induced in the cerebral cortex have not been performed so far. Here, we analyzed the protein and mRNA expression in the cerebral cortex12 h after ischemic injury and repair. Drug intervention using Buchang Naoxintong Jiaonang (BNJ), which has been reported to have good clinical therapeutic effects, was selected for our study of cerebral ischemic repair in rat models. Two powerful techniques can be merged in a single study to examine and yield new perspectives in physiology and pathophysiology. Combining LC–MS/MS and DNA microarray analyses of the rat cerebral cortex confidently identified two large datasets in more than three biological replicates. Quantitative approaches were then used to quantify the differences among the four experimental groups the naive, sham, middle cerebral artery occlusion MCAO and MCAO + BNJ groups by a label-free proteomics approach and a Cy5-labeled microarray approach. In brief, 3217 unique proteins and 24,300 unique gene symbols were confidently identified. Bioinformatics analysis revealed that of these unique proteins and gene symbols, 269 proteins and 632 gene symbols were identified to be differentially expressed. The results of subce...
