Project description:

Title:
Impact of endothelial cell derived lncRNAs for cardiomyocyte signal-transduction and the cardiac stress response
Summary:
We have identified a novel lncRNA, which is secreted by endothelial cells within extracellular vesicles and impacts cardiomyocyte signal-transduction. Using newly generated endothelial specific knock-out mice of this lncRNA, we will assess its functional impact on the myocardial stress response in mouse models of pathological cardiac overload. We will use proteomic and RNA sequencing methods as well as co-culture of endothelial cells and cardiomyocytes to identify and study the molecular mechanism of action of this novel lncRNA.
