| 摘要 |
The invention provides methods and biomarkers for assessing cardiac metabolic response to pharmaceuticals, environmental agents, chemical compounds and biologic therapies. The invention provides methods for identifying cellular metabolites secreted by primary cardiomyocytes, cardiomyocyte precursor cells, clonal cardiomyocytes derived from adult human heart, immortalized cardiomyocytes, human embryonic stem cell (hESC)-derived cardiomyocytes, human induced pluripotent stem cell (iPS)-derived cardiomyocytes, or any cell displaying cardiomyocyte-specific markers in response to exposure to pharmaceuticals, environmental agents, chemical compounds and biologic therapies that are cardiotoxic. Cardiomyocyte-secreted cellular metabolites provide metabolic signatures of cardiotoxicity, and can be used to screen pharmaceutical agents, lead and candidate drug compounds, biologics, and other therapeutics for cardiotoxic effects. |
