Dataset Summary
TitleIntegrated multi-omics analysis of adverse cardiac remodelling and metabolic inflexibility upon ErbB2 and ERR⍺ deficiency
DescriptionFunctional oncogenic links between ErbB2 and ERR⍺ in HER2+ breast cancer patients support a therapeutic benefit of co-targeted therapies. However, ErbB2 and ERR⍺ also play key roles in heart physiology, and this approach could pose a potential liability to cardiovascular health. Using integrated phosphoproteomic, transcriptomic and metabolic profiling, we uncovered molecular mechanisms associated with the adverse remodelling of cardiac functions in mice with combined attenuation of ErbB2 and ERR⍺ activity. Genetic disruption of both effectors results in profound effects on cardiomyocyte architecture, inflammatory response and metabolism, the latter leading to a decrease in fatty acyl-carnitine species further increasing the reliance on glucose as a metabolic fuel, a hallmark of failing hearts. Furthermore, integrated omics signatures of ERR⍺ loss-of-function and doxorubicin treatment exhibit reciprocal features of chemotherapeutic cardiotoxicity. These findings thus reveal potential cardiovascular risks in discrete combination therapies in the treatment of breast and other cancers.
