Glioblastoma multiforme is a lethal disease and represents the most common and severe type of glioma. Drug resistance and the evasion of cell death are the main characteristics of its malignancy, leading to a high percentage of disease recurrence and the patients' low survival rate. Exploiting the modulation of cell death mechanisms could be an important strategy to prevent tumor development and reverse the high mortality and morbidity rates in glioblastoma patients. Ferroptosis is a recently described type of cell death, which is characterized by iron accumulation, high levels of polyunsaturated fatty acid (PUFA)-containing phospholipids, and deficiency in lipid peroxidation repair. Several studies have demonstrated that ferroptosis has a potential role in cancer treatment and could be a promising approach for glioblastoma patients. Thus, here, we present an overview of the mechanisms of the iron-dependent cell death and summarize the current findings of ferroptosis modulation on glioblastoma including its non-canonical pathway. Moreover, we focused on new ferroptosis-inducing compounds for glioma treatment, and we highlight the key ferroptosis-related genes to glioma prognosis, which could be further explored. Thereby, understanding how to trigger ferroptosis in glioblastoma may provide promising pharmacological targets and indicate new therapeutic approaches to increase the survival of glioblastoma patients.
胶质母细胞瘤是一种致命的疾病,代表了最常见和最严重的胶质瘤类型。药物耐药性和细胞死亡逃逸是其恶性肿瘤的主要特征,导致疾病复发率高,患者生存率低。利用细胞死亡机制的调节可能是预防肿瘤发展和逆转胶质母细胞瘤患者高死亡率和发病率的重要策略。铁死亡是一种最近描述的细胞死亡类型,其特征是铁积累、高水平的多不饱和脂肪酸 (PUFA) 含量磷脂和脂质过氧化修复缺陷。多项研究表明,铁死亡在癌症治疗中有潜在作用,可能是胶质母细胞瘤患者的一种有前途的治疗方法。因此,在这里,我们概述了铁依赖性细胞死亡的机制,并总结了铁死亡调节对包括非经典途径在内的胶质母细胞瘤的最新发现。此外,我们专注于用于治疗神经胶质瘤的新型铁死亡诱导化合物,并强调与神经胶质瘤预后相关的关键铁死亡相关基因,这些基因可以进一步探索。因此,了解如何在胶质母细胞瘤中引发铁死亡可能为提供有前途的药理靶点,并指出增加胶质母细胞瘤患者生存率的新治疗方法。
