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 o...

The inflammatory response associated with myocardial and brain ischemia/reperfusion injury (IRI) is a critical determinant of tissue necrosis, functional organ recovery, and long-term clinical outcomes. In the post-ischemic period, reactive oxygen species (ROS) are involved in tissue repair through the clearance of dead cells and cellular debris. Neutrophils play a critical role in redox signaling due to their early recruitment and the large variety of released ROS. Noteworthy, ROS generated during IRI have a relevant role in both myocardial healing and activation of neuroprotective pathways. Anatomical and functional diff...

This study is an extremely important step in assessing the Amplatzer Amulet as an effective non-prescription drug alternative for patients with AFib who are at an increased risk for ischemic stroke." In an email sent to MD+DI, Abbott wrote, “We already have an Amulet IDE trial underway that is intended to support our submission for approval in the U.S. for Amplatzer Amulet. The newly announced CATALYST trial will support our submission for an expanded indication for Amulet as a safe and effective alternative to NOAC drugs for patients with atrial fibrillation and at risk of stroke.”...

AbstractStroke is the second leading cause of death and main cause of disability worldwide, but with few effective therapies. Although stem cell-based therapy has been proposed as an exciting regenerative medicine strategy for brain injury, there are limitations. The developed cerebral organoids (COs) represent a promising transplantation source for stroke that remains to be answered. Here, we transplanted COs at 55  days and explored the feasibility in the rat middle cerebral artery occlusion (MCAO) model of stroke. COs transplantation at 6 h or even 24 h after MCAO significantly reduces brain infarct volum...

Today's open access paper is a review of potential approaches that might be used as a basis for therapies to restore a more youthful level of neurogenesis in the aging mammalian brain. Neurogenesis is the process by which new neurons are created by neural stem cell populations and then integrated into neural networks. In adults, neurogenesis is essential to memory, learning, and the limited degree of regeneration that the brain is capable of enacting. Unfortunately, the supply of new neurons declines with age as the underlying stem cells become ever less active. Beyond making the aging brain more resilient, methods of incr...

Abstract The central nervous system (CNS) has a poor self-repairing capability after injury because of the inhibition of axonal regeneration by many myelin-associated inhibitory factors. Therefore, ischemic stroke usually leads to disability. Previous studies reported that Ginsenoside Rb1 (GRb1) plays a role in neuronal protection in acute phase after ischemic stroke, but its efficacy in post-stroke and the underlying mechanism are not clear. Recent evidences demonstrated GRb1 promotes neurotransmitter release through the cAMP-depend protein kinase A (PKA) pathway, which is related to axonal regeneration. The pres...

Contributors : Yejie Shi ; Jun ChenSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusBlood monocytes/macrophages infiltrate the brain after ischemic stroke and critically influence brain injury and regeneration. We investigated stroke-induced transcriptomic changes of monocytes/macrophages by RNA sequencing profiling, using a mouse model of permanent focal cerebral ischemia. Compared to non-ischemic conditions, brain ischemia induced only moderate genomic changes in blood monocytes, but triggered robust genomic reprogramming in monocytes/macrophages invading the brain. Surprisingly, fun...
