Therapeutic effects of AICAR and DOX conjugated multifunctional nanoparticles in sensitization and elimination of cancer cells via survivin targeting
MetadataShow full item record
Purpose: Resistance to chemotherapy is one of the major problems facing current cancer research. Enhancing tumor cell response to anticancer agents increases chemotherapeutic effectiveness. We have recently addressed this issue and reported on producing multifunctional nanoparticles (Fe3O4@SiO2(FITC)-FA/AICAR/DOX) aiming to overcome chemoresistance with synergetic effect of AICAR and DOX. In the present study, we demonstrated that these nanoparticles not only show enhanced cellular uptake and cytotoxic effect but can also show enhanced pro-apoptotic and anti-proliferative effects in five different tumor-derived cell lines (A549, HCT-116, HeLa, Jurkat and MIA PaCa-2). Methods: The nanoparticles were examined by using flow cytometric analyses of apoptosis and cell cycle. In addition, we performed caspase-3 activity assay, which supported our flow cytometric data. Furthermore, we demonstrated the applicability of this approach in a variety of cancer types confirming the potential widespread utility of this approach. Results: With the concept of co-delivery of AICAR and DOX in the nanoparticle formulation, the use of AICAR against survivin (BIRC5) sensitized cancer cells to DOX chemotherapy which resulted in effective cancer cell elimination. These result showed that combination therapy involving both a molecularly targeted therapy and chemotherapeutic agent has the ability to retain and enhance therapeutic efficacy. Conclusion: Fe3O4@SiO2(FITC)-FA/AICAR/DOX nanoparticles is superior to monotherapy via the synergetic effect of AICAR and DOX and also the nanoparticle formulation could overcome issues of toxicity with targeted therapy while maintaining the potent anticancer effects of AICAR and DOX.
