Conclusions In summary, we made a dual antitumor therapy for bladder cancer. It really is primarily based on paclitaxel encapsulated in P- polymer nanoparticles and siRNA survivin-loaded poly(beta aminoester) nanoparticles. Our results recommend that both nanoparticles were efficiently formed, with properties that could enable their intravesical administration, therefore decreasing invasiveness and also the not-selective intravenous route. Each and every monotherapy was capable to significantly minimize the growth of two bladder tumor cells in vitro. Nonetheless, the combination therapy didn’t improve the tumor cell killing. This unexpected impact was further studied and attributed to the presence of nuclear vs. cytoplasmatic survivin isoforms combined with all the cell cycle arrest developed by nuclear survivin, that is incompatible with the paclitaxel mode of action. Therefore, we could not confirm our hypothesis: survivin silencing does not sensitize bladder cell lines to paclitaxel.Pharmaceutics 2021, 13,17 ofSupplementary Materials: The following are out there online at https://www.mdpi.com/article/10 .3390/pharmaceutics13111959/s1.
