Dose response curves for various formulations against Panc-1 cells. For in vitro cytotoxicity assay, Panc-1 cells were treated with M-PLDUs, PLDUs, and FD at various DOX concentrations (A), or USPIOs at various Fe concentrations (B); PBS was set as control group in both experiments.
Notes: Cell viability was analyzed by MTT assay and calculated as a percentage of living cells. Each point represents the mean ± SD (n = 3).
Abbreviations: FD, free doxorubicin; DOX, doxorubicin.
