Circular RNAs (circRNAs) are covalently closed and stable functional RNA molecules. Through broad RNA-sequencing, we identified hundreds of heart-specific and species-conserved circRNAs in murine and human hearts. We characterised circINSR and circREGEN in depth as therapeutic targets to prevent anthracyclin-related cardiotoxicity and to affect cardiac regeneration, respectively. We now aim to gain detailed insight into their cardioprotective molecular mechanisms. In addition, we will identify novel circRNAs through the combination of our custom circRNA-specific Cas13 sgRNA library with in-house developed screening platforms for cardiomyocyte apoptosis and proliferation.
