Stimuli-responsive polymer nanocarriers, capable of exploiting subtle changes in the tumor microenvironment for controlled drug release, have gained significant attention cancer therapy. Notably, NAD(P)H: quinone oxidoreductase 1 (NQO1), found to be upregulated various solid tumors, represents a promising therapeutic target due its effective capability enzymatically reduce trimethyl-locked (TML) benzoquinone structures physiological condition. In this study, novel redox-sensitive carbonate monomer, MTC, was synthesized, and amphiphilic block copolymers were prepared through ring-opening polymerization. By successfully self-assembling poly(ethylene glycol)-b-PMTC micelles, model doxorubicin (DOX) encapsulated with high efficiency. The micelles exhibited redox-responsive behavior, leading rapid release. vitro assessments confirmed their excellent biocompatibility hemocompatibility. Furthermore, inhibition NQO1 enzyme reduced release NQO1-overexpressed cells but not control cells, resulting decreased cytotoxicity presence inhibitors. Overall, study showcases potential MTC-based polycarbonate achieve targeted specific enzyme-mediated microenvironment. Therefore, self-assembly polymers into nanomicelles holds immense promise as intelligent nanocarriers delivery applications.

Sunitinib resistance is a major challenge in advanced renal cell carcinoma (RCC). Clinically, elucidating the underlying mechanisms and developing practical countermeasures for sunitinib RCC desirable. In previous studies, we found that circAGAP1 expression was significantly upregulated clear (ccRCC) strongly associated with poor prognosis. However, role of ccRCC remains unclear. We used public databases bioinformatics analysis to identify binding targets circAGAP1. Additionally, effects on proliferation, clonogenesis, apoptosis, migration cells were analyzed using quantitative real-time PCR, counting kit-8 assays, apoptosis colony formation assays. Furthermore, RNA immunoprecipitation, dual-luciferase reporter, fluorescence situ hybridization assays explore molecular mechanism. this study, exhibited higher sunitinib-sensitive inhibited after treatment. Mechanical studies revealed regulated target platelet-derived growth factor receptor by acting as microRNA sponge suppresses miR-149-5p, miR-455-5p, miR-15a-5p simultaneously. Overexpression these three miRNAs reversed circAGAP1-mediated sensitivity ccRCC. summary, our findings indicate may serve promising biomarker predict sensibility therapeutic
