英文摘要 | Multidrug resistance (MDR) remains one of the main challenges in the successful chemotherapy of human cancer. RNA interference (RNAi) strategy aiming at only one cause of MDR was widely applied, nevertheless hardly obtained satisfactory tumor-suppressing effect. In this work, a new attempt to package two kinds of RNA with different functions into one vector and reverse MDR against two different mechanisms via RNAi was carried out. A new bioreducible poly (beta-amino esters) (PAEs), poly[bis(2-hydroxylethyl)-disulfide-diacrylate-beta-tetraethylenepentamine] (PAP) was synthesized by Michael addition reaction. The PAEs/RNA complex nanoparticles (PAEN) were prepared. The experimental results demonstrated that co-delivery of iMdr-1-shRNA and iSurvivin-shRNA could be achieved by a single vector, and interfering two genes simultaneously had a synergistic effect on overcoming MDR. PAEN lowered the IC50 value of doxorubicin (DOX) in MDR tumor cells to a comparable level to that in the sensitive cell line through down-regulating the expression of P-gp and Survivin, and decreased the tumor volumes in mice xenograft model bearing DOX-resistant human breast cancer when combined with DOX. These results illustrated that PAEN could be applied as potential efficient non-viral RNA carriers for reversing MDR. (c) 2012 Elsevier Ltd. All rights reserved. |
