Supplementary Figure 1: Assessment of kidney cancer cell lines A498, 786-O, and A704 via flow cytometry revealed surface expression of P-gp in all lines; Supplementary Figure 2: 786-O and A704 cells were transduced with lentiviral FR1, and flow cytometric analysis shows increased surface FR1 expression; Supplementary Figure 3: NCI/ADR-RES or NCI/ADR-RES-FR cells with known FR levels were treated with increasing concentrations (10-9 M to 10-5 M) of vintafolide for 2 h; Supplementary Figure 4: Ovarian tumors positive for P-gp tend to express lower levels of FR; Supplementary Table 1: P-gp inhibitor elacridar reverses P-gp-mediated DAVLBH and vintafolide resistance; Supplementary Table 2: Functional multi-drug transporter efflux assay.
