p53 Pathway

p53是最重要的肿瘤抑制基因之一，常被称为“基因组守护者”。在几乎所有的癌症中，都存在 p53基因或其调控回路中的一部分发生基因突变，由此可见其重要性。它通过防止由细胞应激或DNA损伤导致突变来保护基因组的稳定性。 p53通过调节细胞凋亡、抑制细胞周期进程、细胞分化、细胞生长阻滞及加速DNA修复来维持基因组的稳定。 p53是在哺乳动物细胞中保持低水平的特异性DNA结合转录因子， p53具有非常短的半衰期，因而在非应激细胞内几乎检测不到。这主要是在其抑制因子MDM2作用下，通过p53持续的泛素化和后期通过26S蛋白酶体降解实现。DNA损伤等细胞应激信号会抑制p53的泛素化，并导致其稳定和活化。一旦p53活化，将会与其下游目标的调控元件结合并调控其转录。从而可以启动基于p53的不同肿瘤抑制功能的多种细胞治疗方案。
