Abstract
The emergence of multidrug treatment resistance presents a hurdle for the successful chemotherapy of tumours. Ferroptosis, resulting from the iron-dependent accumulation of lipid peroxides, has the potential to reverse multidrug resistance. However, simultaneous delivery of the iron sources, ferroptosis inducers, drugs, and enhanced circulation carriers within matrices remains a significant challenge. Herein, we designed and fabricated a defect self-assembly of metal-organic framework (MOF)-red blood cell (RBC) membrane-camouflaged multi-drug-delivery nanoplatform for combined ferroptosis-apoptosis treatment of multidrug-resistant cancer. Ferroptosis and chemotherapeutic drugs are embedded in the centre of the iron (III)-based MOF at defect sites by coordination with metal clusters during a one-pot solvothermal synthesis process. The RBC membrane could camouflage the nanoplatform for longer circulation. Our results demonstrate that this defect self-assembly-enabled MOF-membrane-camouflaged nanoplatform could deplete the glutathione, amplify the reactive oxidative species oxidative stress, and enable remarkable anticancer properties. Our work provides an alternative strategy for overcoming multidrug resistance, which could regulate the fluidity and permeability of the cell membrane by ferroptosis to downregulate of P-glycoprotein protein expression by ferroptosis. This defect self-assembly-enabled MOF-membrane-camouflaged multi-drug-delivery nanoplatform has great therapeutic potential.
