ABSTRACT

The target of rapamycin (TOR) kinase is part of an evolutionarily conserved signaling pathway that coordinates cell growth, survival, and autophagy. Previously, pharmacological studies using rapamycin have suggested a cardioprotective effect of TOR signaling inhibition on cardiomyopathy. We found that rapamycin exerts a conserved cardioprotective effect in two adult zebrafish models of cardiomyopathy of different etiology, and provided the first genetic evidence to support a long-term cardioprotective effect of TOR signaling inhibition. Moreover, we detected dynamic TOR-autophagy activities along different stages of cardiomyopathy. This needs to be considered when developing TOR-autophagy-based therapeutics for cardiomyopathy.
