Over expression of IL-32β- exaggerated myocardial injury after ischemia and reperfusion in mice model




Interleukin-32 (IL-32) is discovered as proinflammatory cytokine by inducing IL-1β, IL-6, IL-8, and tumor necrosis factor (TNF)-α. However, there are unclear data regarding IL-32β associated with worsening of myocardial injury after cardiac ischemia and reperfusion (I/R). In this study, we investigate the prognostic value of IL-32β in inflammatory response after myocardial injury. Anesthetized mice subjected to the myocardial ischemia for 30 min and 2 hours reperfusion. Expression and Regulation of IL-32β were measured by RNA Isolation and Real-Time Polymerase Chain Reaction, inflammatory response in blood and myocardial tissue, were assayed accordingly by ELISA and Western blotting, while Echo for cardiac elements measurement. The I/R group had a significantly higher expression level of IL-32β (0.643±0.012, vs. sham group 0.121±0.013; P<0.05) and associated with worsen myocardial injury, and low cardiac function. In-conclusion, IL-32β might be a new marker associated with adverse event after myocardial injury and may contribute with cardiac remodeling.
