GPLD1 and neoplasm: Since the tumor cell uptake of PLAD-MLP is as low as that of PLD and PL-MLP, as shown by the drug levels presented in Figure 5, and liposomal Ald (i.e., PLA) has negligible cytotoxicity in vitro on tumor cell lines[6], we would expect the cytotoxic effect of PLAD-MLP to be similar to that of the combination of PLD and PL-MLP.
