Chamber–Specific Molecular Profiling of Doxorubicin-Induced Cardiotoxicity via Integrated Multi-Omics Analysis [PDF]

Metabolites
Background: Doxorubicin (Dox) induces dose-dependent Dox–induced cardiotoxicity (DIC), but the chamber-specific molecular mechanisms remain unclear, as traditional analyses rely on whole-heart homogenates.
