Here, we engineer an injectable, mucoadhesive hydrogel-mediated tri-modal nanoplatform designed for localized CRC therapy by integrating smart chemotherapy delivery with externally activatable PTT and radiosensitization. Core-shell AuNP@mesoporous silica nanoparticles were loaded with 5-fluorouracil (5-FU) and functionalized with a pH/ROS-responsive linker and hyaluronic acid (HA) to enable CD44-mediated tumor targeting and microenvironment-triggered \"uncapping\"/drug release. The targeted nanocarriers were embedded within a chitosan/acellular fish skin (CS/AFS) hydrogel to form a local depot intended to prolong tumor-site residence and reduce systemic exposure. In vitro, the complete nine-group panel demonstrated stepwise gains from targeting, hydrogel confinement, and external activation. The tri-modal condition (Gel-tNP + 808-nm NIR + 2-Gy X-ray) produced the strongest cytotoxicity, approaching near-complete ablation in HCT-116 cells and reproducing the efficacy hierarchy in a second CRC line (SW480), while normal colon epithelial cells (NCM460) maintained higher viability across matched conditions, supporting an initial therapeutic window. Mechanistically, the tri-modal regimen generated the highest intracellular ROS levels, amplified early γH2AX DNA double-strand break signaling and increased damage persistence, and drove extensive cell death consistent with synergistic chemo-photothermal-radiotherapy action (e.g., ~ 9% viability and ~ 5.6-fold LDH release vs. control in the tri-modal group).

The in situ generation of multiple ROS species was directly confirmed by mass spectrometry using a TEMPO probe and by fluorescence imaging with ROS-sensitive dyes, while scavenger assays verified the ROS-dependent nature of viral inactivation.

Curcumin (Cur) is a natural polyphenol with anti-inflammatory and anti-angiogenic properties that holds promise for therapeutic applications. However, its clinical utility is limited due to poor solubility and instability. To address these challenges, we developed a curcumin-loaded silk fibroin nanoparticle (Cur-SN) delivery system to inhibit VEC infiltration and promote cartilage regeneration. Cur-SNs were prepared and characterised to evaluate their physicochemical properties. The effects of Cur-SN on VEC apoptosis and senescence were assessed, and the underlying mechanism by which Cur-SN regulates mitochondrial homeostasis via the Drp1/ROS pathway was investigated. Additionally, a rat knee cartilage defect model was established, in which Cur-SN combined with a BMSC-loaded hydrogel was implanted. Cartilage differentiation and VEC infiltration levels in newly formed tissues were subsequently analysed. In vitro experiments demonstrated that Cur-SN upregulated Drp1 and ROS levels, leading to mitochondrial homeostasis disruption. This, in turn, induced VEC apoptosis and senescence while significantly inhibited VEC infiltration. Furthermore, Cur-SN effectively counteracted the inhibitory effects of VEC activation on BMSC chondrogenic differentiation. In vivo experiments revealed that Cur-SN reduced VEC infiltration and angiogenesis in newly formed tissues, thereby promoting hyaline cartilage regeneration at the defect site. Cur-SN enhances cartilage repair by upregulating Drp1 expression and ROS levels, thereby disrupting mitochondrial homeostasis, inducing VEC apoptosis and senescence, and inhibiting VEC infiltration.</p>","PeriodicalId":15053,"journal":{"name":"Journal of Biological Engineering","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12955002/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146105590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
