Copper‐Based Composites Nanoparticles Improve Triple‐Negative Breast Cancer Treatment with Induction of Apoptosis‐Cuproptosis and Immune Activation

Advanced Healthcare Materials, Год журнала: 2024, Номер 13(28)

Опубликована: Июль 12, 2024

The synergistic effect of apoptosis and cuproptosis, along with the activation immune system, presents a promising approach to enhance efficacy against triple-negative breast cancer (TNBC). Here, two prodrugs are synthesized: reactive oxygen species (ROS)-responsive prodrug PEG-TK-DOX glutathione (GSH)-responsive PEG-DTPA-SS-CPT. These self-assembled chelated Cu2+ prepare nanoparticle PCD@Cu that simultaneously loaded doxorubicin (DOX), camptothecin (CPT), Cu2+. elevated levels ROS GSH in TNBC cells disrupted structure, leading release Cu+, DOX, CPT depletion GSH. DOX triggered immunogenic cell death (ICD) cells. Simultaneously, downregulated expression copper transporting ATPase 2 (ATP7B), causing significant accumulation ions This further induced aggregation lipoylated dihydrolipoamide S-acetyltransferase (DLAT) downregulation iron-sulfur (Fe-S) cluster proteins, ultimately cuproptosis ICD TNBC. In vitro vivo experiments confirmed activated demonstrating strong anti-tumor capabilities. Moreover, exhibited an excellent biosafety profile. Overall, this study provides strategy for effective therapy.

An Electron Transfer Mediated Mechanism for Efficient Photoreforming of Waste Plastics Using a Ni₃S₄/ZnCdS Heterojunction

Advanced Materials, Год журнала: 2025, Номер unknown

Abstract The oxidative degradation of plastics in conjunction with the production clean hydrogen (H 2 ) represents a significant challenge. Herein, Ni 3 S 4 /ZnCdS heterojunction is rationally synthesized and employed for efficient H high‐selectivity value‐added chemicals from waste plastic. By integrating spectroscopic analysis techniques density functional theory (DFT) calculations, solely electron transfer‐mediated reaction mechanism confirmed, wherein extracts electrons ZnCdS (ZCS) to promote spatial segregation photogenerated holes, which not only facilitates but also maintains high oxidation potential holes on ZCS surface, favoring hole‐dominated plastic oxidation. Notably, catalyst exhibited rates as 27.9 17.4 mmol g −1 h , along selectivity 94.2% 78.3% liquid product toward pyruvate acetate polylactic acid (PLA) polyethylene terephthalate (PET), respectively. Additionally, carbon yields 26.5% 2.2% are measured after 9 photoreforming, representing highest values reported date. Overall, this research presents promising approach converting into fuel valuable chemical products, offering solution growing issue “ White Pollution ”.
