摘要 Abstract

中文摘要
本研究探索了磁电金属有机框架(MOFs)在诱导胶质母细胞瘤(GBM)铁死亡中的创新应用,旨在同时变革治疗精准性和诊断效能。MOFs凭借其可调的化学和物理特性,可作为精准肿瘤学的多功能平台。在此,磁电MOFs被设计用于利用电磁场,调节细胞内铁的氧化还原状态,以提升活性氧(ROS)生成并驱动脂质过氧化——铁死亡(一种独特的铁依赖性程序性细胞死亡形式)的标志。为增强肿瘤特异性,这些MOFs与细胞外囊泡(EVs)偶联,实现向GBM细胞的选择性递送并最小化脱靶毒性。这一靶向系统不仅改善了治疗疗效,也减少了副作用。此外,磁电MOFs与MRI兼容,允许实时肿瘤成像和精确定位。这种诊断-治疗双重能力提供了一种强大的非侵入性治疗策略。除直接细胞毒性外,MOF诱导的铁死亡促进肿瘤相关抗原的释放,触发免疫激活并可能启动免疫原性细胞死亡(ICD)。这种免疫调节效应通过重塑肿瘤微环境扩大了治疗获益。总的来说,这一基于MOF的多功能平台整合了诊断、治疗和免疫原性调节,代表了治疗最具侵袭性和治疗抗性的癌症之一的范式转变。

This study explores the innovative application of magnetoelectric metal-organic frameworks (MOFs) for inducing ferroptosis in glioblastoma (GBM), aiming to transform both therapeutic precision and diagnostic efficacy. MOFs, with their tunable chemical and physical properties, serve as versatile platforms for precision oncology. Here, magnetoelectric MOFs are engineered to harness electromagnetic fields, regulating intracellular iron redox states to elevate reactive oxygen species (ROS) production and drive lipid peroxidation-the hallmark of ferroptosis, a distinct iron-dependent form of programmed cell death.To enhance tumor specificity, these MOFs are conjugated with extracellular vesicles (EVs), enabling selective delivery to GBM cells and minimizing off-target toxicity. This targeted system not only improves therapeutic efficacy but also reduces side effects. Moreover, the magnetoelectric MOFs are MRI-compatible, allowing real-time tumor imaging and precise localization. This dual diagnostic-therapeutic capacity offers a powerful, non-invasive treatment strategy.Beyond direct cytotoxicity, MOF-induced ferroptosis promotes the release of tumor-associated antigens, triggering immune activation and potentially initiating immunogenic cell death (ICD). This immunomodulatory effect broadens therapeutic benefit by reshaping the tumor microenvironment. Collectively, this multifunctional MOF-based platform integrates diagnostics, therapy, and immunogenic modulation, representing a paradigm shift for treating one of the most aggressive and therapy-resistant cancers.
