The combination of phototherapy with oxaliplatin (OXA) represents a potent strategy for triggering immunogenic cell death (ICD) and elicit robust antitumor immunity. In this study, we construct IROTD nanoparticles (IROTD NPs) through self-assembly of a norcantharidin (NCTD)-OXA-conjugated polymer (P2) and the near-infrared (NIR) photosensitizer DTIR780. Under 808 nm laser irradiation, IROTD NPs generate heat and reactive oxygen species (ROS) while release OXA and NCTD, result in severe DNA damage and potent induction of ICD within tumor cells. Concurrently, NCTD inhibits DNA repair mechanisms and down-regulates PD-L1expression, thereby increase the infiltration of cytotoxic T-cell and amplify systemic antitumor immunity. Leverage the enhanced permeability and retention (EPR) effect, IROTD NPs efficiently accumulate at tumor sites, result in remarkable inhibition of tumor growth and recruitment of CD4 + and CD8 + T lymphocytes, which collectively contribute to the activation of a systemic antitumor immunity. In a bilateral tumor model, IROTD NPs effectively inhibit both primary and distant tumor growth. Overall, this work presents a rationally designed combinatorial nanoplatform that effectively ignites systemic immune response, thus establish a prospective chemo-immunotherapeutic stratagem for cancer treatment.

The design of multimechanistic conjugates based on 10-hydroxycamptothecin (10-HCPT) offers a promising approach to reduce toxicity and enhance antitumor efficacy. We designed and synthesized a novel series of conjugates by linking melampomagnolide B (MMB) to 10-HCPT/SN-38 via diverse linkers. Among them, 6i1/6i2 exhibited remarkable anticolorectal cancer potency and minimal cytotoxicity toward normal THLE-2 cells. Mechanistic studies indicated that 6i1/6i2 could inhibit IκB kinase β (IKKβ), leading to the inhibition of p65 and IκBα phosphorylation, suppression of p65 nuclear translocation, and subsequent regulation of genes controlled by nuclear factor kappa-B (NF-κB). Additionally, they targeted topoisomerase I (Topo I), inducing DNA damage, reactive oxygen species (ROS) accumulation, mitochondrial membrane potential loss, and S-phase arrest. In a CT-26 xenograft model, 6i1 and 6i2 (5 mg/kg) potently suppressed tumor growth, achieving TGI rates of 89.9% and 95.4% without observable toxicity.

Ant–hemipteran mutualism is mediated by honeydew through long-term coevolution. To clarify the feeding preferences for the main honeydew components (sugars and amino acids) in the red imported fire ant,Solenopsis invictaBuren (Hymenoptera: Formicidae), this study employed a self-developed feeding preference assay system to systematically determine the feeding and attraction preferences of workers for ten sugars, eleven amino acids, and their different concentrations and combinations in both laboratory and field experiments. Results showed that: (1)S. invictaworkers exhibited a significant feeding preference for sucrose and leucine among all tested sugar and amino acid solutions; (2) Feeding preferences for both sucrose and leucine were concentration-dependent. Specifically, preferences for 20% sucrose and 0.5% leucine were significantly higher than for lower concentrations, while not significantly different from higher concentrations; (3) The feeding preference for 10% sucrose or 0.5% leucine alone was higher than that for multi-sugar mixtures or a mixture of all eleven amino acids. However, a mixture of sucrose and leucine solutions significantly enhanced field attraction compared to single solutions of sucrose or leucine. The self-developed feeding preference assay system provides a new tool for measuring feeding preferences in ant colonies under near-natural conditions. Overall, this study systematically clarifies the feeding preference for key nutrients inS. invictaworkers and establishes a critical theoretical basis for understanding its foraging ecology and developing highly effective liquid baits.

Background Glioblastoma (GBM) remains a therapeutic challenge with limited treatment options and poor prognosis. 18β-Glycyrrhetinic acid (GA), a natural metabolite from licorice, has shown anti-tumor potential, but its pharmacological effects in GBM and the underlying mechanisms require systematic investigation. Methods The anti-GBM activity of GA in vitro was evaluated in GBM cells using CCK-8, colony formation, wound healing, and flow cytometry assays. Intracranial and subcutaneous GBM models in C57BL/6 and nude mice were established to assess the in vivo pharmacological effects of GA. An integrative approach combining network analysis, transcriptomic sequencing, and TCGA data analysis was employed to explore key genes and pathways. Molecular docking predicted GA binding to MAPK11, and Western blotting assessed its impact on p38 signaling pathway. Results GA significantly inhibited GBM cell proliferation, migration, and induced apoptosis in vitro . In vivo , GA treatment markedly suppressed tumor growth in both intracranial and subcutaneous models, with no observed toxicity. Integrated bioinformatics analysis revealed that high MAPK11 (p38-pathway) expression was significantly associated with poor patient prognosis in TCGA. Molecular docking confirmed a strong binding affinity between GA and MAPK11. Mechanistically, GA downregulated MAPK11 expression, activated p38 signaling pathway, and subsequently suppressed the MEK/ERK signaling pathway. Conclusion This study demonstrats that GA exerted potent anti-GBM effects by regulating p38 signaling pathway, provides novel mechanistic insights, and positions its as a promising therapeutic candidate against GBM.

The poor prognosis of esophageal carcinoma (ESCA) highlights the need to identify novel targets for ESCA treatment. We found that inhibitor of differentiation 4 (ID4) was decreased in ESCA tumor tissues and its expression was associated with the survival of ESCA patients. However, the role of ID4 in ESCA remains unclear. Here, in this study, we found that overexpression of ID4 suppressed the cell proliferation of ESCA in vitro as well as tumor growth in vivo, whereas knockdown of ID4 presented the opposite trend. On the other hand, ESCA cells with overexpression of ID4 reduced macrophage migration and M2 polarization. However, significant increases in macrophage migration and M2 polarization were observed in cultures with ID4 silence. Interestingly, CCL2 was found to mediate the function of ID4 on macrophage polarization. Mechanistically, we identified for the first time that ID4 interacted physically with TCF4 to inactivate TCF4 transcriptional activity, which led to a decrease in CCL2 expression. Moreover, RNA binding protein cell cycle associated protein 1 (CAPRIN1) bound to ID4 mRNA and downregulated its stability, which may contribute to its low expression in ESCA. Taken together, these results support a novel hypothesis that ID4 downregulation may contribute to the development of ESCA by interacting with TCF4, resulting in abnormal proliferation of ESCA cells and tumor-associated macrophage infiltration. ID4 may contribute to the innovation of ESCA biotherapy.
Implications: ID4 inhibits ESCA through suppresses cancer cell proliferation and macrophage M2 polarization, and ID4 could be a potential prognostic marker for patients with ESCA.

Efficient and sustainable degradation of antibiotic pollutants remains a major challenge in electrochemical advanced oxidation processes. Here, we report a tungstate-assisted electro-Fenton strategy that enables rapid removal of sulfamethoxazole (SMX) at near-neutral pH, in which the oxidant is generated in situ from dissolve oxygen to drive the electro-Fenton process without the need for external oxidants. Sodium tungstate (Na 2 WO 4 ), serving as both electrolyte and redox co-catalyst, facilitates homogeneous Fe 2+ /Fe 3+ cycling and in situ hydrogen peroxide generation, while also inducing the formation of a conformal FeWO 4 interfacial layer on the iron anode. Kinetic studies show a pseudo-first-order rate constant of 0.1560 min −1 , representing more than a 14-fold enhancement over conventional Na 2 SO 4 electrolyte. Comprehensive characterization using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and Nyquist plots have indicated the dynamic nucleation of the FeWO 4 layer. Results of electron paramagnetic resonance (EPR) spectroscopy combined with radical scavenging tests revealed that the layer promotes surface-bound hydroxyl radical (•OH) generation, while suppressing iron dissolution and sludge formation. Additionally, UPLC-QTOF-MS/MS analysis identified key SMX degradation intermediates, confirming both homogeneous and interfacial oxidation pathways. Notably, Raman spectroscopy analysis detected the formation of peroxotungstate species (e.g., WO 2 (O 2 ) 2 2− ), indicating tungstate's participation in redox-mediated radical generation. Therefore, the co-designed electrolyte-electrode system integrates bulk-phase catalysis and interface-directed activation, achieving high degradation efficiency while reducing pollutant toxicity. This work offers a modular strategy for electrolyte-guided interfacial engineering and presents a practical design paradigm for electrochemical removal of sulfonamide antibiotics and similar micropollutants.

The pandemic-scale progression of type 2 diabetes mellitus (T2DM) necessitates innovative interventions targeting the pathogenic triad of insulin resistance, dysregulation of lipid metabolism, and gut microbiome dysbiosis. Here, we report a synthetically bioengineered probiotic consortium (REcN-F/Ca) developed through directed metabolic adaptations of Escherichia coli Nissle 1917 (EcN) under iterative hydrogen peroxide selection, subsequently functionalized with fructooligosaccharide-calcium carbonate composites. REcN-F/Ca exhibits enhanced reactive oxygen species tolerance through upregulated antioxidant enzymes and hydrogen sulfide-mediated redox balancing, alongside improved gastrointestinal survivability. In high-fat diet-induced obese male mice, REcN-F/Ca restores gut microbiota diversity, enriches butyrogenic taxa (Lachnospiraceae and Blautia ), and rescues short-chain fatty acids depletion. Transcriptomic profiling reveals PPAR signaling activation, driving lipid metabolism and suppressing adipose inflammation. These effects translate to systemic metabolic improvements with attenuated weight gain (−25.4%), restored glucose homeostasis, and reduced insulin resistance (HOMA-IR: −73.2%) in the obesity and T2DM murine model. Our findings establish REcN-F/Ca as a synthetically engineered probiotic that simultaneously corrects intestinal ecological perturbations and reverses host metabolic dysfunction, proposing a paradigm for metabolic syndrome management.

Highly wet, dynamic, inflammatory, and fouling environments were significant challenges in the healing of diabetic oral ulcers. Inspired by the oral mucosa, a wet-adhesion Janus hydrogel (WAJH) with asymmetric bifunctionalities of antifouling/antioxidant was proposed for diabetic oral ulcer treatment. In the WAJH, the antifouling layer was composed of the agar/polyacrylamide double-network (Agar/PAAm DN) hydrogel, and the wet-adhesive layer was constructed by the poly(acrylic acid-co-2-phenoxyethyl acrylate)/tannic acid (PAEA/TA) hydrogel. The antifouling layer mimicked the oral epithelium to prevent pollutant invasion, and the adhesive layer imitated the basement membrane of oral mucosa to adhere firmly to wet diabetic oral ulcers. Importantly, the adhesion energies of the two layers were distinctly different, measuring 15 J m −2 for the antifouling layer and 316 J m −2 for the adhesive layer, respectively. Notably, TA not only significantly enhanced the toughness and wet adhesion but also endowed the WAJH with reactive oxygen species (ROS) scavenging and antioxidant capabilities. The WAJH remarkably accelerated the healing of oral ulcer by inhibiting inflammation at the ulcer, promoting angiogenesis, and promoting re-epithelialization in vivo. Consequently, the WAJH with antifouling and antioxidant exhibited promising prospects in the clinical treatment of diabetic oral ulcer.

The clinical care of diabetic chronic wounds faces the dilemma that traditional dressings cannot simultaneously achieve real-time status monitoring and synergy treatment, while existing intelligent dressings are restricted in clinical application due to their reliance on external power sources. To tackle this, this study develops a self-powered enzymatic biofuel cell (EBFC) with protein hydrogel patch electrodes for personalized and intelligent wound care. Using bovine serum albumin/polypyrrole as the electrode scaffold, the cathode patch is fabricated with zeolitic imidazolate framework-8 (ZIF-8), while the anode patch is constructed by incorporating glucose oxidase-loaded ZIF-8. Inside, enzymatic cascades leverage hyperglycemia to generate antibacterial reactive oxygen species, which synergize with near-infrared photothermal effects to boost antibacterial efficacy; meanwhile, inter-electrode microelectric fields accelerate cell migration. It also monitors battery output voltage to provide real-time feedback on wound glucose levels for wound assessment. Integrating synergistic antibacterial activity, migration acceleration, and real-time monitoring, this EBFC creates an integrated diabetic wound diagnosis-treatment platform. In vitro/in vivo tests confirm its good biocompatibility, effective promotion of infected diabetic wound healing, and potential to advance intelligent wound care as a novel biomedical strategy.

The photo-Fenton method presents a promising approach for wastewater treatment, yet it faces several significant challenges, including the continuous supply of H 2 O 2 , slow mass transfer rates and a limited operational pH range. In this context, we describe the successful preparation of a novel catalyst: n-p type graphitic carbon nitride nanosheets engineered with nitrogen vacancies and decorated with Cu 2 O-T, which is characterized by controllable crystal planes. This photo-self-Fenton-like catalyst is designed for the in-situ production and activation of H 2 O 2 . The optimized catalyst, CNC-20, demonstrates remarkable efficiency in degrading various organic pollutants, showcasing high cyclic stability and wide applicability. Notably, CNC-20 achieves a degradation rate of 98.8% for tetracycline hydrochloride within 60 min, with a reaction rate constant 4.2 times greater than that of pristine carbon nitride. Characterization studies illustrate that the construction of ultrathin carbon nitride nanosheets featuring nitrogen vacancies, combined with the co-exposure of Cu 2 O-T crystalline planes (111) and (100), significantly enhances carrier separation efficiency, thereby facilitating effective H 2 O 2 generation. Furthermore, Cu 2 O-T plays a crucial role in the direct capture of in-situ generated H 2 O 2 , rapidly activating it to generate abundant ·OH, which effectively mitigates the issue of slow mass transfer associated with H 2 O 2 . This study presents a novel approach integrating in-situ H 2 O 2 generation and activation, effectively overcoming the inherent limitations of traditional photo-Fenton reactions and providing a promising strategy for pollutant degradation in wastewater treatment systems.

Residual organophosphorus pesticides (OPs) in food pose a severe threat to public health, necessitating simple and sensitive on-site analytical methods. In this study, a signal-off electrochemical sensing platform for OPs was constructed based on the OP-induced inhibition of silver deposition triggered by red kidney bean esterase (RKBE), coupled with the signal amplification of a CuNi dual-atom catalyst (CuNi-DAC). RKBE catalyzes the hydrolysis of α-naphthyl acetate to produce α-naphthol, which reduces Ag⁺ to Ag 0 deposited on the electrode. The electroactive Ag 0 undergoes oxidation to generate a prominent oxidation current, providing a sensitive sensing signal for detection. CuNi-DAC modification of the electrode accelerates charge transfer, provides more active sites, and effectively amplifies the sensing signal. Upon exposure to OPs, the activity of RKBE is inhibited, thereby suppressing the production of α-naphthol. This leads to a diminished Ag 0 generation and subsequent a weakened oxidation current. The decrease degree of current signal shows a positive correlation with pesticide concentration. Under optimized conditions, the fabricated sensing platform exhibits a good linear response range of 10 pmol/L-1000 pmol/L for fenthion with a low detection limit of 5.4 pmol/L. Spiked recoveries in cabbage and apple samples ranged from 93.3% to 108.5%, validating the sensing platform's practicality and reliability. This work offers a facile and cost-effective electrochemical sensing approach for on-site screening of OPs.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease that primarily affects the colon and rectum and is characterized by diffuse, superficial inflammation of the colonic mucosa. The excessive production of reactive oxygen species (ROS) plays a pivotal role in immune dysregulation and the pathogenesis of UC. However, current treatment options are limited by poor absorption, rapid metabolism, and systemic side effects due to the lack of targeted delivery. Therefore, there is an urgent need for therapies capable of specifically scavenging ROS. In this study, we developed a ROS-responsive nanoscavenger system, Fucoidan-TK-Resveratrol@Curcumin (FTR@Cur), based on the marine-derived polysaccharide fucoidan, and loaded with the natural compound curcumin (Cur) for the treatment of UC. The nanoscavenger was constructed using fucoidan (Fuc) as the hydrophilic backbone, while resveratrol (Res) was conjugated via a ROS-sensitive thioketal (TK) linker, enabling targeted ROS clearance. The resulting FTR@Cur nanoparticles had a mean particle size of 92.17 nm, a zeta potential of −22.2 mV, and an encapsulation efficiency and drug loading of 69.0% and 5.5%. FTR@Cur exhibited excellent ROS-scavenging ability and biocompatibility, effectively modulating the inflammatory and immune microenvironment in the colon. This system enhanced colonic barrier function, reduced inflammation, and offers a promising therapeutic strategy for UC.
