The Study on Gβγ complex Regulates TNF Induced Cell Necrosis

Abstract

早期的研究认为细胞坏死是不受信号通路调控的。然而近几年的研究发现细胞坏死和细胞凋亡一样同样存在着信号通路的转导。由受体相互作用蛋白1(RIP1)和受体相互作用蛋白3(RIP3)等蛋白组成的坏死复合体在细胞坏死信号中扮演着决定性角色。尽管最近的研究发现了一些影响坏死信号的蛋白,但坏死复合体如何形成及其如何影响下游底物并导致最终细胞坏死的机制依然不清楚。 本文通过逆转录病毒随机插入染色体破坏基因的方法在鼠成纤维细胞系L929中筛选对肿瘤坏死因子(TNF)抗性的突变株。通过鉴定发现其中一株突变株是由于逆转录病毒插入到鸟嘌呤核苷酸结合蛋白γ亚基10(GNG10)的第一个外显子和第二个外显子中间,影响...Previously researches showed that cell necrosis is not regulated by signaling pathways. Recently more and more evidences showed that necrosis, like apoptosis, is under control of some certain signaling pathways. Necrosis complex, principally consisted of receptor interaction protein 1(RIP1) and RIP3, plays a key role in necrosis pathway. Although many other new proteins had been found to regulate ...学位:理学博士院系专业:生命科学学院_生物化学与分子生物学学号:2172009015355
