Abstract
We applied a novel profiling approach using receptor binding domain (RBD) ligands to cell surface domains of a panel of nutrient transporters to characterize the impact of a number of tyrosine kinase inhibitor anticancer drugs on human stem cell–derived cardiomyocytes. High-content screening and flow cytometry analysis showed diagnostic changes in nutrient transporter expression correlating with glycolysis and oxidative phosphorylation–based cell metabolism in glucose and galactose media. Cluster analysis of RBD binding signatures of drug-treated cells cultured in glucose medium showed good correlation with sensitization of mitochondrial toxicity in cells undergoing oxidative phosphorylation in galactose medium. These data demonstrate the potential for RBD ligands as profiling tools to improve the clinical predictivity of in vitro cell assays for drug toxicity.
