The correct duplication and transfer of genetic material to daughter cells is the major event of cell division. Dysfunction of DNA replication or chromosome segregation presents challenges in cancer initiation and development as well as opportunities for cancer treatment. Cyclic GMP-AMP synthase (cGAS) of the innate immune system detects cytoplasmic DNA and mediates downstream immune responses through the molecule stimulator of interferon genes (STING). However, how cytosolic DNA sensor cGAS participates in guaranteeing accurate cell division and preventing tumorigenesis is still unclear. Recent evidence indicates malfunction of cGAS/STING pathway in cancer progression. Cell cycle-targeted therapy synergizes with immunotherapy via cGAS/STING activation, leading to promising therapeutic benefit. Here, we review the interactions between cell cycle regulation and cGAS/STING signaling, thus enabling us to understand the role of cGAS/STING in cancer initiation, development, and treatment.
正确的遗传物质复制和传递到子细胞是细胞分裂的主要事件。DNA 复制或染色体分离功能障碍在癌症的发生和发展中带来了挑战，同时也为癌症治疗提供了机会。先天免疫系统中的环鸟苷酸-腺苷酸合成酶 (cGAS) 检测细胞质 DNA，并通过干扰素基因刺激物 (STING) 分子介导下游免疫反应。然而，细胞溶质 DNA 传感器 cGAS 如何参与保证准确的细胞分裂和预防肿瘤发生仍然不清楚。最近的证据表明，cGAS/STING 通路在癌症进展中的功能障碍。细胞周期靶向治疗通过 cGAS/STING 的激活与免疫疗法协同作用，带来了有前景的治疗益处。在这里，我们综述了细胞周期调控与 cGAS/STING 信号之间的相互作用，从而使我们能够理解 cGAS/STING 在癌症发生、发展和治疗中的作用。
