Stress granule (SG) assembly is a conserved cellular strategy to minimize stress-related damage and promote cell survival. Beyond their fundamental role in the stress response, SGs have emerged as key players for human health. As such, SG assembly is associated with cancer, neurodegenerative disorders, ischemia, and virus infections. SGs and granule-related signaling circuits are therefore promising targets to improve therapeutic intervention for several diseases. This is clinically relevant, because pharmacological drugs can affect treatment outcome by modulating SG formation. As membraneless and highly dynamic compartments, SGs regulate translation, ribostasis and proteostasis. Moreover, they serve as signaling hubs that determine cell viability and stress recovery. Various compounds can modulate SG formation and dynamics. Rewiring cell signaling through SG manipulation thus represents a new strategy to control cell fate under various physiological and pathological conditions.
应激颗粒(SG)组装是一种保守的细胞策略,用于最小化与应激相关的损伤并促进细胞存活。除了在应激反应中的基本作用外,SG 还成为了人类健康的关键因素。因此,SG 组装与癌症、神经退行性疾病、缺血和病毒感染有关。因此,SG 组装和与颗粒相关的信号转导回路是改善几种疾病治疗干预的有前途的靶点。这在临床上是相关的,因为药理药物可以通过调节 SG 的形成来影响治疗效果。作为无膜和高度动态的隔室,SG 调节翻译、核糖体稳定和蛋白质稳定。此外,它们作为信号枢纽,决定细胞活力和应激恢复。各种化合物可以调节 SG 的形成和动力学。通过 SG 操作重排细胞信号转导,因此代表了一种在各种生理和病理条件下控制细胞命运的新策略。
