ABSTRACT
There is now substantial evidence that myocardial ischemiareperfusion (IR) injury affects the spinal cord and brain, and that interactions may exist between these two systems. In the present study, the spinal cord proteomes were systematically analyzed after myocardial IR injury, in an attempt to identify the proteins involved in the processes. The myocardial IR injury rat model was first established by cross clamping the left anterior descending coronary artery for 30min ischemia, followed by reperfusion for 2 h, which resulted in a significant histopathological and functional myocardial injury. Then using the stable isotope dimethyl labeling quantitative proteomics strategy, a total of 2,362 shared proteins with a good distribution and correlation were successfully quantified. Among these proteins, 33 were identified which were upregulated and 57 were downregulated in the spinal cord after myocardial IR injury, which were involved in various biological processes, molecular function and cellular components. Based on these proteins, the spinal cord protein interaction network regulated by IR injury, including apoptosis, microtubule dynamics, stressactivated signaling and cellular metabolism was established. These heartspinal cord interactions help explain the apparent randomness of cardiac events and provide new insights into future novel therapies to prevent myocardial I/R injury.
