High-dose radiotherapy (>8–10 Gy) causes rapid endothelial cell death via acid sphingomyelinase (ASMase)–induced ceramide production, resulting in biologically significant enhancement of tumor responses. To further augment or solicit similar effects at low radiation doses, we used genetic and chemical approaches to evaluate mechano-acoustic activation of the ASMase-ceramide pathway by ultrasound-stimulated microbubbles (USMB).

酸性鞘磷脂酶和神经酰胺在机械声增强肿瘤放射反应中的作用

大剂量放疗(> 8-10 Gy)通过酸性鞘磷脂酶(ASMase)诱导的神经酰胺产生,导致内皮细胞快速死亡,从而在生物学上显着增强了肿瘤反应。为了进一步增强或征求低辐射剂量下的类似效果,我们使用了遗传和化学方法来评估超声刺激的微泡(USMB)对ASMase-神经酰胺途径的机械声激活。
