Abstract
Combined cancer treatment via co-delivery of siRNAs and an anticancer drug can be a promising strategy due to the synergistic effect of simultaneously minimizing gene/drug administration. In this study, Bcl-xL siRNA and doxorubicin (DOX) are encapsulated into designed methoxy-poly(ethylene glycol)-block-poly(D,L-lactic acid) (mPEG-b-PLA) block copolymer polymersomes (PSomes). A study of the cytotoxicity of Bcl-xL siRNA and DOX co-encapsulated PSomes (CPSomes) shows more inhibited proliferation of MKN-45 and MKN-28 human gastric cancer cell lines than only gene- and drug-loaded ones. Consequently, these results demonstrate that co-delivery of genes and drugs using PSomes results in a synergistic efficacy and indicates the potential of PSomes as efficient nanocarriers for combined cancer therapy.
