Thrombopoietin (TPO) protects against heart damage induced infarction in rat model

ABSTRACT: In order to examine the mechanism of TPO on cardiac protection against myocardial infarction damage (MI), we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to delineate the TPO cardioprotective mechanism against infarction.

Project description:Inflammatory response plays a bidirectional regulatory role in myocardial infarction (MI). TLR signaling pathway plays an important role in the development of inflammation. Additionally, we discovered that CCRR is an anti-arrhythmic lncRNA in a prior work. Here we show, it is decreased in mice with 3-day MI followed by a sharp increase of pro-inflammatory cytokines and activation of the TLR pathway. Overexpression of CCRR could effectively inhibit the inflammatory response, reduce the infarct area, and improve cardiac function. And also reduced hypoxia-induced inflammation in cardiomyocytes and macrophages induced by IFN and LPS. It produced a similar protective effect in cardiomyocytes co-cultured with macrophages. Through microarray analysis, RNA-binding protein immunoprecipitation analysis, and other related experiments verification, TLR2 and TLR4 may be as potential targets of CCRR after MI. Our findings provide the evidence that lncRNA CCRR plays a key cardioprotective role against MI injury by targeting the TLR signaling pathway. nflammatory response plays a bidirectional regulatory role in myocardial infarction (MI).
