英文摘要Drug resistance is a main obstacle for the successful chemotherapy of lung cancer. In this work, a new co-delivery system, P85-PEI/TPGS/PTX/shSur complex nanoparticles (PTPNs), to overcome paclitaxel (PTX) resistance in A549 human lung cancer was designed and developed. The experimental results showed that PTPNs could facilitate drug into cells and induce survivin shRNA (shSur) into nuclei on A549 and A549/T cells, achieve efficient gene delivery and induce availably RNA interference on A549/T cells. The IC50 of PTPNs against A549/T cells was 360-fold lower than that of free PTX. The enhanced efficacy of PTPNs against A549/T cells was associated with PTX-induced apoptosis and cell arrest in G2/M phase. Down-regulation of survivin protein by PTPNs could lower the apoptosis threshold of drug resistant cells and render chemotherapeutic agents more effective. Moreover, the inhibition of GST activity by P85 was found to increase PTX accumulation in A549/T cells. The in vivo antitumor efficacy showed that PTPNs were more effective than that of the Taxol. As a result, the co-delivery of PTX and shSur by PTPNs could be a very powerful approach to improve the therapeutic effect of PTX in resistant lung cancer. (C) 2012 Elsevier Ltd. All rights reserved.
