摘要
尽管人们一直在努力寻找有效的治疗策略,但胶质母细胞瘤(GBM)仍然是一个治疗难题,预后存活率很低。在过去十年中,应激反应在 GBM 治疗中的作用受到了广泛关注,因为根据这些细胞程序的持续时间和强度,它们可以起到细胞保护作用,也可以促进癌细胞死亡。因此,UPR、自噬或氧化应激的启动可能会阻碍或促进药物介导的细胞杀伤。在这篇综述中,我们总结了在 GBM 的发展和进展过程中调节 ER 应激、自噬和氧化应激的机制,随后讨论了这些应激途径在不同治疗反应中的参与情况。我们还讨论了精确了解不同药剂诱发的应激反应的分子调控机制将如何决定性地促进针对脑部恶性肿瘤的新型、更有效的联合疗法的设计。
Cellular stress responses as modulators of drug cytotoxicity in pharmacotherapy of glioblastoma
Despite the extensive efforts to find effective therapeutic strategies, glioblastoma (GBM) remains a therapeutic challenge with dismal prognosis of survival. Over the last decade the role of stress responses in GBM therapy has gained a great deal of attention, since depending on the duration and intensity of these cellular programs they can be cytoprotective or promote cancer cell death. As such, initiation of the UPR, autophagy or oxidative stress may either impede or facilitate drug-mediated cell killing. In this review, we summarize the mechanisms that regulate ER stress, autophagy, and oxidative stress during GBM development and progression to later discuss the involvement of these stress pathways in the response to different treatments. We also discuss how a precise understanding of the molecular mechanisms regulating stress responses evoked by different pharmacological agents could decisively contribute to the design of novel and more effective combinational treatments against brain malignancies.
