Co-delivery of insulin-like growth factor 1 receptor specific siRNA and doxorubicin using chitosan-based nanoparticles enhanced anticancer efficacy in A549 lung cancer cell line. Artif Cells Nanomed Biotechnol. 2017 Mar 31;:1-10 Authors: Shali H, Shabani M, Pourgholi F, Hajivalili M, Aghebati-Maleki L, Jadidi-Niaragh F, Baradaran B, Movassaghpour Akbari AA, Younesi V, Yousefi M Abstract 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. PMID: 28362176 [PubMed - as supplied by publisher]
