We investigated the synergism between shRNAs against Bcl-xL and doxorubicin (DOX) using aptamer-conjugated polyplexes (APs) in combination cancer therapy. Synergistic and selective cancer cell death was achieved by AP-mediated co-delivery of very small amounts of DOX and Bcl-xL-specific shRNA, which
