The performance of the materials, however, can be impaired by the intrinsic antioxidant defense mechanism in organisms, such as autophagy.Methods: The nanoscale metal-organic frameworks (nMOFs), nMIL-100 (Fe), were exploited and characterized. Also, the Fenton-like catalytic characteristics, anti-endometrial cancer (EC) effects and potential mechanisms of nMIL-100 (Fe) nanoparticles were investigated in vitro.Results: The synthesized nMIL-100 (Fe) nanocatalyst catalyzed hydroxyl radicals (·OH) production in the presence of hydrogen peroxide (H2O2) and simultaneously depleted intracellular glutathione (GSH). Combining with H2O2, nMIL-100 (Fe) nanoparticles exhibited enhanced cytotoxicity for EC cells, especially for progesterone treatment-insensitive KLE cells, probably due to relatively lower expression of the catalase gene. The accumulated ·OH initiated PTEN induced putative kinase 1 (PINK1)/E3 ubiquitin-protein ligase Parkin-mediated cytoprotective mitophagy in turn to partially rescue ·OH-induced cell apoptosis. Furthermore, both pretreatments of EC cells with siRNA-mediated Parkin knockdown and Mdivi-1 (a mitophagy inhibitor) addition were sufficient to ensure nMIL-100 (Fe) synergizing with H2O2-induced oxidative damages.Conclusion: These results suggest that the degree of mitophagy should be taken into consideration to optimize therapeutic efficiency when developing ROS based-CDT for EC cancer therapies. Therefore, a nMIL-100 (Fe)-guided, elevated ROS and overwhelmed mitophagy-mediated therapeutic strategy may have greater promise for EC therapy compared with current treatment modalities.Keywords: mitophagy, chemodynamic therapy, metal-organic frameworks, nanocatalyst, endometrial cancerGong XPu XWang JYang LCui YLi LSun XLiu JBai JWang YDove Medical Pressarticlemitophagychemodynamic therapymetal-organic frameworksnanocatalystendometrial cancerMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 6661-6679 (2021) |
