© 2017 Informa UK Limited, trading as Taylor & Francis Group Here, we investigated the effects of dual delivery of IGF-1R siRNA and doxorubicin by chitosan nanoparticles on viability of A549 lung cancer cells line by utilization of MTT and qRT-PCR. Furthermore apoptosis and migration of treated cells were assessed by Annexin-PI and wound healing assays, respectively. The chitosan nanoparticles had about 176 nm size with zeta potential and polydispersive index about 11 mV and 0.3, respectively. The IGF-1R siRNA had synergistic effect on DOX-induced cytotoxicity and apoptosis in tumour cells. In addition, siRNA/DOX-loaded chitosan nanoparticles could significantly decrease migration and expressions of mmp9, VEGF and STAT3 in A549 cells.
