Transferrin targets the liposomes to cancer cells expressing increased levels of the transferrin receptor.17–19 The ratio of mebendazole to docetaxel in the combination liposomes was stable at 9:1, and the liposomal formulations were all <150 nm in size (<200 nm is essential for the enhanced permeation and retention (EPR) effect) (Supplementary Table S4). This evidence concerns the gene TFRC and cancer.
