Anthracycline-induced cardiotoxicity associates with a shared gene expression response signature to TOP2-inhibiting breast cancer drugs in cardiomyocytes

E. Renee Matthews, Omar D. Johnson, K Horn…·Michelle C. Ward

The paper investigates the shared gene expression response to TOP2-inhibiting breast cancer drugs in cardiomyocytes and identifies genetic factors associated with inter-individual variation in cardiotoxicity.
