A retrospective study was conducted on 128 patients diagnosed with MGC between December 2020 and January 2022. Demographic, clinical, pathological, surgical, and postoperative follow-up data were collected from the medical records. Patients were divided into two groups based on their total aesthetic outcome score: the satisfied group (score ≥27, n=87) and the dissatisfied group (score <27, n=41). Additionally, patients were categorized into recurrence (n=29) and non-recurrence groups (n=99) based on postoperative recurrence status.

By examining gene expression patterns - particularly immune checkpoint and TNFRSF genes - the study aimed to assess the immune state of cancer PBMCs. Surprisingly, half of the tumor PBMCs exhibited downregulation of both immunosuppressive genes (Pdcd1, Ctla4, Tigit) and immune activation molecules (CD27, CD357), suggesting immune inactivity rather than suppression. Additionally, cytokine expression varied significantly, with upregulation of IL-18 and IL-7, despite their controversial roles in tumor progression. Analysis of T-cell exhaustion markers did not reflect established exhaustion signatures, implying a naive-like immune state. Instead, a distinct immune signature emerged, characterized by the broad downregulation of TNFRSF genes (TNFRSF18, TNFRSF14, TNFRSF6, and CD27). We designated this group as PI (PBMC-impaired). Deconvolution of bulk RNA-seq data further revealed a significant reduction in CD4+ T cells and a lower CD4+/CD8+ ratio in the PI group.

Repurposing marketed non-cancer drugs in oncology is emerging as a fast-tracking approach to speed up the development of new treatment options, urgently needed for DMG. Repurposed anthelmintic mebendazole (MBZ) is in the spotlight against brain tumors, because it joins promising anticancer properties with high neuropenetrance, favorable pharmacokinetic and safety profile. Although MBZ is undergoing Phase I/II trials against brain tumors, including DMG, MBZ anticancer properties and the underlying mechanisms of actions have poorly been characterized in DMG preclinical models. We found that MBZ robustly reduced cell viability in six out of seven DMG cell lines with either K27M-mutated or wild-type H3. All IC<sub>50</sub> values (range 102 to 958 nM) fell in a clinically attainable range. The antiproliferative MBZ properties were mediated by an arrest of DMG cells in the G<sub>2</sub>/M phase with a concomitant upregulation of the key cell cycle regulators p21 and p27, whereas p53 upregulation and activation were cell context-dependent. At the same growth-inhibitory concentrations, MBZ triggered apoptotic cell death, as evidenced by higher levels of the apoptotic markers caspase-3 and PARP cleavage. Consistently, Annexin V-Propidium iodide (PI) double staining showed MBZ dose-dependent increase in both stages of apoptosis. Of interest, the combination of MBZ with the first-in-class imipridone ONC201 sinergistically increased the antiproliferative effects in two DMG cell lines as assessed by combination scores with different algorithms, showing additive effects in two others cell lines. Mechanistically, the combination potentiated the proapoptotic activity of either MBZ or ONC201, while not changing the cytokinetic perturbations induced by the single drugs. Finally, one pair of ONC201-sensitive and ONC201-resistant DMG cell lines with acquired resistance showed same responsiveness to MBZ with similar values of IC<sub>50</sub> and E<sub>max</sub>. In conclusion, MBZ demonstrates high growth-inhibitory/proapoptotic activity, chemosensitization property to ONC201 and the ability to overcome ONC201 resistance in DMG cell cultures, proposing as a new low-toxicity therapeutic for DMG, with a potential to be used in second-line treatment and/or in combination protocols.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"15 6","pages":"2701-2718"},"PeriodicalIF":3.6,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12256405/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
