Targeting tumor markers is one of the most important approaches to therapy, and "suicide" pattern marker response a very challenging study. Telomerase, as key factors associated with human longevity cancer progression, considered be an emerging biomarker for diagnosis. The targeted drug delivery nanobomb─BIBR1532@HSN/FQDNA/MUC1 aptamer (B@HDA) prepared in this study based on hollow silica nanoparticles (HSN) CRISPR systems. Amino-modified FQDNA amino-modified MUC1 are covalently attached surface carboxyl-functionalized HSN. modified directs nanobomb specifically target breast cells (MCF-7) sequesters telomerase inhibitor (BIBR1532) within Telomerase primers (TPs) recognized by highly expressed MCF-7 elongated form DNA substrates. substrate pairs crRNA bases effectively activate CRISPR-Cas12a. activated CRISPR-Cas12a precisely cut FQDNA, releasing BIBR1532, which inhibits activity. This strategy achieves "suicide". described above has following advantages. (1) "closing" effect contributes reducing nonspecific release BIBR1532. (2) B@HDA, combined CRISPR, regulates mitochondrial dysfunction cell senescence cells. (3) In tumor-bearing mouse model, exhibits good biocompatibility obvious ablation tumors, suggesting potential application prospects across wide range lines. summary, proposed provides tunable switch approach specific inhibition reduction growth, representing promising avenue promoting treating cancer.

Starvation therapy mediated by glucose oxidase is a widely used therapeutic approach for tumor treatment, but it limited the simultaneous drawbacks of weak efficacy, nonspecificity, and systemic toxicity. Thus, combination was to complement strategy anticancer therapy. On basis starvation therapy, we designed catalytic model nanosheets with biological cascade enzymes synergizing drugs. In short, two (glucose horseradish peroxidase) are covalently immobilized on Ti3C2 MXene nanosheet enzyme nanoreactor formed electrostatically adsorbing positive charged DOX. Finally, outer layer coated hyaluronic acid. By combining oxidase-mediated photothermal chemotherapy, have achieved effect "killing three birds one stone" dual stimulation response endogenous exogenous sources site. This method not only achieves targeting cancer cells also improves toxicity reduced efficacy realizes synergistic enhanced reactions. It opens up new path research nanomedicine.

Abstract Cuproptosis is a newly discovered copper‐dependent form of cell death. Intracellular glutathione (GSH) acts as copper chelator to inhibit cuproptosis, so the reduction GSH concentration conducive enhancing cuproptosis cells. In order reduce content and interfere with mitochondrial metabolism, strategy based on calcium overload depletion enhance proposed in this study. Containing manganese (Mn) (Cu) elements, CaCO 3 nanoparticles (NPs) are modified MCF‐7 aptamer (CaCO /Mn/Cu@lip‐Apt). When entering cell, /Mn/Cu@lip‐Apt decomposed released Mn* (Mn 2+ /Mn 3+ 4+ ), Cu Ca . The high valence Mn ion can effectively consume produce which catalyzed H 2 O reactive oxygen species (ROS), while reducing concentration. production ROS promoted influx exogenous large accumulation led intracellular overload, resulting dysfunction metabolism disorders. , turn triggered cuproptosis. This showed excellent antitumor effects provided new way study disease treatment.

Reactive Oxygen Species (ROS) therapy based on metal ion catalysis had attracted much attention due to its high selectivity for tumour cells and lower side effects. Copper ions (Cu2+) show great potential in their efficient fenton-like catalysis. However, the accumulation utilisation efficiency of copper within cell was limited, hence need delivery Cu2+ into cell. Curcumin (CUR) not only acted as a ligand bind ions, but also an electron donor increase catalytic Cu+ enhance generation ROS. Calcium carbonate (CaCO3) nanoparticles good biocompatibility, alleviated microacidic environment tumours released calcium (Ca2+) trigger overload leading apoptosis. Therefore, present study, CaCO3 (CRC@lip) loaded with curcumin were designed modified liposomal surface improve stability dispersion vivo. CRC@lip generated higher activity by releasing Cu2+, reacting glutathione (GSH). catalyzed highly toxic ·OH radicals H2O2, while property CUR further enhanced dispersal nanoparticles. The electron-donor effect amplified killing through interaction This strategy improved therapeutic effect, may reduce effects traditional chemotherapeutic drugs, providing new way thinking cancer treatment.
