If you are traveling, you might be asked to walk through a scanner. But are those scanners safe? Here's everything you need ...

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 ...
