However, as different adjuvants induce distinct immune cell and antibody (Ab) responses, selecting the right adjuvants remains challenging. Here, we evaluated the following vaccine adjuvants to promote protection against tumor-growth in mice and correlated IgG subclass and Fc N-glycosylation responses: Alum; the toll-like receptor activators Poly(I:C) and MPLA; Alum-Poly(I:C); and the more inflammatory water-in-oil adjuvants Montanide, IFA, CFA, and M.tb.-enriched (e)CFA. While Alum and Montanide failed to protect, MPLA and IFA tended to protect, and Poly(I:C), Alum-Poly(I:C), CFA, and eCFA significantly protected against tumor-growth. Across all adjuvants, tumor-protection correlated with the induction of highly activating IgG2(c/b) Abs and afucosylated (F0) IgG1 Abs, the latter showing up to 5% abundance. While all adjuvants transiently induced IgG1 F0 following initial immunization, Poly(I:C)- and eCFA-induced memory responses also generated IgG1 F0 after repeated antigen-exposure without adjuvants. Additionally, Poly(I:C)-induced tumor-protection was associated with high IgG2c/IgG1 ratios, high levels of IgG galactosylation and sialylation, and IFNγ-producing CD8 + Tc1-cells. Conversely, Ova-eCFA-induced tumor-protection was additionally associated with high levels of IgG across all subclasses, but low levels of galactosylation and sialylation, and CD8 + Tc17- and CD4 + Th17-cells. Accordingly, tumor protecting adjuvants may induce common but also different protecting programs. A tumor-antigen-specific IgG2a monoclonal (m)Ab protected against tumor-growth in both its de-galactosylated and galactosylated plus sialylated forms, suggesting common and possibly distinct protective mechanisms.

In this study, we demonstrated that patient-derived BM-CAFs significantly enhanced NSCLC cell proliferation, migration, invasion and therapeutic resistance in vitro. Mechanistically, BM-CAFs promoted epithelial-mesenchymal transition (EMT) and cancer stem cell (CSC) phenotypes through upregulation of key transcription factors. In-vivo experiments showed that co-injection of NSCLC cells with BM-CAFs accelerated tumor growth and enhanced cisplatin resistance. Molecular analysis revealed these effects were mediated through distinct mechanisms whereby IL26 activated the JAK-STAT3 pathway, while CX3CL1 activated both JAK-STAT3 and AKT-mTOR pathways. Importantly, neutralizing antibodies against IL26 and CX3CL1 effectively suppressed their respective signaling pathways and reversed EMT and CSC characteristics.

Although conventional PI3Kα inhibitors (e.g., Alpelisib) have shown efficacy in extending progression-free survival in patients with PI3Kα-mutant breast cancer, their clinical application remains constrained by off-target toxicities, particularly hyperglycemia, which limits dosing and therapeutic feasibility. Building on recent preclinical findings, this study introduces BBO-10203, a first-in-class, orally bioavailable small-molecule inhibitor targeting the RAS-PI3Kα interaction. The compound is rationally designed to selectively and covalently bind to Cysteine 242 (Cys242) within the Rat Sarcoma (RAS)-Binding Domain (RBD) of PI3Kα, thereby effectively disrupting RAS-mediated PI3Kα activation. This unique mechanism confers potent in vivo antitumor activity while preserving insulin-regulated glucose metabolism, thereby mitigating metabolic adverse effects.</p>","PeriodicalId":12180,"journal":{"name":"Experimental Hematology & Oncology","volume":"14 1","pages":"115"},"PeriodicalIF":13.5,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482239/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145191552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
