该团队通过体内和体外实验研究了STING如何响应DNA辐射损伤，发现了辐射导致的DNA损伤可以激活PARP1蛋白，诱导多聚核糖（PAR）过度合成，进而触发STING蛋白介导的细胞死亡。研究显示，对于STING基因缺陷的小鼠，对其腹部辐射后，相对于正常小鼠，存活率提升5倍，即从11%跃升至67%，肠道病理损伤显著减轻。研究通过给予低剂量的PARP1抑制剂PJ34来下调PAR合成，可以抑制STING激 ...

2025年2月13日，中国科学院广州生物医药与健康研究院副研究员孙益嵘团队和美国加州大学洛杉矶分校合作在Cell Death & Differentiation期刊发表题为“STING directly interacts with PAR to promote apoptosis upon acute ionizing radiation-mediated DNA ...

米托蒽醌作为 Usp11 的抑制剂，给予野生型小鼠米托蒽醌处理后进行 TBI，结果显示米托蒽醌干预使 Usp11+/+ 小鼠脾脏边缘区变窄，减轻了电离辐射后 MZ B 细胞数量的减少。流式细胞术分析表明，米托蒽醌处理后，Usp11+/+ 小鼠受 TBI 后 MZ B 细胞的总百分比显著高于 PBS 处理组，且血清 IgM 水平变化表明米托蒽醌干预减少了抗体类型的转变。这说明靶向 Usp11 ...
