Table S1.Genes associated with doxorubicin pharmacokinetics or pharmacodynamics in cancer cells or cardiomyocytes as identified in the PharmGKB knowledgebase. Those genes identical to and related to genes significantly changing expression upon acquisition of doxorubicin resistance in MCF-7 breast tumour cells by microarray analysis (false discovery rate of 0.01) are listed in bold regular font and bold italics font, respectively. The fold change in gene expression is also listed for upregulated (+) or down regulated (−) genes.

Table S2.Over-representation of doxorubicin pharmacokinetic or pharmacodynamic genes in the dataset of genes associated with the acquisition of doxorubicin resistance in MCF-7 breast tumour cells. The p values assessing the significance of this over-representation are depicted in parentheses, with statistically significant p values listed in bold font.

Table S3.Differences in doxorubicin and doxorubicinol DNA binding parameters. DNA binding by doxorubicin or doxorubicinol was compared in an ethidium bromide displacement assay as described in Materials and Methods. The Bmax and Kapp values for doxorubicin and doxorubicinol are listed, along with the p values for significant differences in their binding parameters (p < 0.05).
