Project description:Cardiac fibrosis is a common feature of ischemic heart disease and cardiac fibroblasts (CF) are key players in cardiac remodeling of the injured heart after myocardial infarction (MI). Fibrosis increases myocardial stiffness, thereby impairing cardiac function, which ultimately progresses to end-stage heart failure. Little is known, however, on the secretome of CF and cell-to-cell communication of CF is only incompletely understood. Here, we in vivo labeled secreted proteins by expressing TurboID under control of the POSTN promotor in cardiac fibroblasts of mouse with myocardial infarction, enriched biotinylated proteins and analyzed them using LC-MS.

Project description:In this study, we used a cardiac-specific, inducible expression system to activate YAP in adult mouse heart. Activation of YAP in adult heart promoted cardiomyocyte proliferation and did not deleteriously affect heart function. Furthermore, YAP activation after myocardial infarction (MI) preserved heart function and reduced infarct size. Using adeno-associated virus subtype 9 (AAV9) as a delivery vector, we expressed human YAP in the murine myocardium immediately after MI. We found that AAV9:hYAP significantly improved cardiac function and mouse survival. AAV9:hYAP did not exert its salutary effects by reducing cardiomyocyte apoptosis. Rather, we found that AAV9:hYAP stimulated adult cardiomyocyte proliferation. Gene expression profiling indicated that AAV9:hYAP stimulated cell cycle gene expression, enhanced TGFβ-signaling, and activated of components of the inflammatory response.Cardiac specific YAP activation after MI mitigated myocardial injury after MI, improved cardiac function and mouse survival. These findings suggest that therapeutic activation of hYAP or its downstream targets, potentially through AAV-mediated gene therapy, may be a strategy to improve outcome after MI. Three groups were involved in this study: sham group, AAV9:Luci+MI group and AAV9-YAP+MI group. Each group contained three biological replicates. The sham group had neither myocardial infarction nor AAV injection. The AAV9:Luci +MI(L for brief) group had myocardial infarction and injected with AAV9:Luic. The AAV9:hYAP+MI(YAP for brief) group had myocardial infarction and injected with AAV9:hYAP. 5 days after MI and AAV injection, the heart apexes were collected and the total RNA were isolated for microarray analysis.

Project description:Comparison of both LncRNAs and mRNAs expression in the border zone of the myocardial infarction rats and the sham operation rats Border zone (BZ) of the myocardial infarction is critical to patients. Current treatments of myocardial infarction are primarily aimed to save the dying myocardial cell in the border zone. During myocardial infarction, certain changes in BZ, e.g, apoptosis, fibrosis, inflammation, etc, played an important role in deciding the survival. Impairment and recovery of BZ has been linked to gene expression changes. The aim of our study was to obtain a global expression profile of lncRNAs and mRNAs of the border zone in Wistar rats myocardial infarction, and identify the changes during myocardial infarction.

Project description:It remains unclear how sleep influences inflammatory pathways after myocardial infarction (SF). In this study, we relied on established murine models and assessed how sleep fragmentation (SF) alters transcriptional programing in the blood, heart, and brain after MI.

Project description:Neuregulin-1 (NRG-1) is a paracrine factor critical for cardiac development. We have been examining whether the recombinant NRG-1β isoform known as glial growth factor 2 (GGF2) has therapeutic potential for heart failure. In both small and large animals after experimental myocardial infarction (MI) we have found that GGF2 treatment improves myocardial function and limits progressive myocardial remodeling. To understand potential mechanisms for this effect, we compared gene expression in swine by microarray analysis. We used microarrays to compared th the global gene expression underlying the efficacy of GGF2 treatment for heart injury. Left ventricular tissue remote from the site of infarct was collected from each of 8 animals (3 untreated controls, 3 low dose GGF2-treated and 2 high dose GGF2-treated) and processed for gene expression microarray analysis using Affymetrix porcine genome GeneChips.
