However, in solid tumors, aberrant vasculature and an immunosuppressive microenvironment often restrict immune-cell infiltration, thereby weakening the immune benefits of PDT. Here, we develop an ICD-amplifying, self-assembled nanoparticle-hydrogel composite (methacrylate-functionalized fucoidan hydrogel [dFuGMA]-Ce6-Tas nanoparticles [CTNPs]) for local immunotherapy following melanoma resection. In this system, the photosensitizer chlorin e6 and the immunomodulatory/antiangiogenic agent tasquinimod (Tas) spontaneously coassemble into carrier-free nanoparticles (CTNPs), which are subsequently embedded in a photocrosslinkable dFuGMA to enable <i>in situ</i> gelation and coordinated therapy at the surgical site. <i>In vitro</i>, CTNPs markedly enhanced cellular uptake, reactive oxygen species generation, and ICD-associated responses. In a postoperative melanoma model, dFuGMA-CTNPs combined with laser irradiation significantly suppressed tumor regrowth and promoted immune activation, as evidenced by increased dendritic cell maturation (4.6-fold) and enhanced infiltration of CD4<sup>+</sup> (4.8-fold) and CD8<sup>+</sup> T cells (5.8-fold). Mechanistically, Tas induced tumor vascular normalization by downregulating the hypoxia-inducible factor 1-alpha/vascular endothelial growth factor axis, thereby synergistically potentiating PDT-triggered ICD and downstream immune responses. Transcriptomic profiling further confirmed modulation of pathways associated with \"immune response\" and \"T cell activation.\" In conclusion, dFuGMA-CTNPs achieves a dual-pathway synergy through ICD enhancement and vascular normalization, providing a precisely localized and translationally feasible immunotherapeutic strategy to prevent postoperative melanoma recurrence.</p>","PeriodicalId":19530,"journal":{"name":"Omics A Journal of Integrative Biology","volume":" ","pages":"15578100261488096"},"PeriodicalIF":2.0,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149063540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transcriptomic data were obtained from the Gene Expression Omnibus (GSE301181), and donor-matched proteomic data were deposited in Figshare. miRNA-mRNA correlations and miRNA-protein associations were evaluated through integrative correlation and interaction analyses, followed by functional enrichment and network modeling. Thirteen differentially expressed miRNAs were identified and showed widespread negative correlations with 710 differentially expressed genes. In contrast, proteomic integration identified a more restricted subset of 229 miRNA-associated differentially expressed proteins. Functional enrichment revealed broad distribution of miRNA-mRNA associations across extracellular matrix organization, immune signaling, and cell migration pathways, whereas miRNA-protein associations converged on a limited set of biological processes with higher enrichment ratios. Several miRNAs were linked to known fibrosis- and stress-related targets, supporting biological relevance. Together, these findings suggest that integrated protein-level analysis helps refine fibrosis-relevant miRNA regulatory programs in IPF fibroblasts and may improve biological interpretation of disease-associated molecular changes.</p>","PeriodicalId":19530,"journal":{"name":"Omics A Journal of Integrative Biology","volume":" ","pages":"541-550"},"PeriodicalIF":2.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148423079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
