细胞内NF-kB的活化过程受到精细调控。通常情况下,在细胞质中的NF-kB处于失活状态,与抑制蛋白IkB(inhibitory protein of NF-kB)结合成三聚体复合物。当出现TNF-a信号、炎症因子以及LPS、紫外线等外界刺激时,细胞因子与细胞膜表面的TNF受体结合后,TNF受体发生多聚化并与细胞质中TRADD分子发生相互作用。TRADD招募TRAF(...
Indeed, the levels of NFKBIA and the NF-κB precursor NFKB1 were reduced in KRAS-mutant cells, which were restored by the suppression of TBK1. Additional experiments found that mutant KRAS and TBK1 were required for the nuclear accumulation of the NF-κB subunit REL, as well as the ...

RAS在体内调控着多种信号通路,研究最多的主要包括以下三种信号通路:(1)PI3K-AKT-mTOR通路,对细胞增殖分化凋亡、葡萄糖转运等细胞生命活动有重要影响;(2)Ras-Raf-MEK-ERK信号通路,参与调控细胞增殖、分化、迁移、免疫应答等生命活动;(3)Ras-Ral A/B-NF-kB信号通路,参与调控细胞增殖、生命周期等生命活动。
肝癌的病因繁多,过程复杂,其发生机理尚不清楚.体外研究表明Ras信号通路在肝癌发生,发展中起到重要作用.实验室曾利用白蛋白启动子诱导Ras癌基因在肝细胞中特异性表达,成功建立了Ras转基因肝癌小鼠模型.最近几年的研究结果表明NF-kB信号转导通路与肿瘤的发生,发展,抗凋亡,侵袭和转移都有着非常重要的关系[1]. 本实验...
AKT further hinders apoptosis by phosphorylating the IkB repressor of NFkB. Stimulus of Rac causes among other things (see RacPathway) the activation of NFkB. Ras also stimulates the mitogen-activated kinases ERK1/2 via the Raf1 cascade. The Erk kinases translocate to the nucleus where they ...
华北理工大学附属医院甄琪教授研究发现RasGRP1在银屑病小鼠和人皮肤的活化T细胞中的表达显著增加,表皮VEGF通过RasGRP1-AKT-NF-KB途径增加炎性因子的产生,Rasgrp1过表达与敲除可显著影响银屑病小鼠皮肤炎症。哈尔滨医科大学附属第二医院柏冰雪教授针对银屑病共发疾病病如白癜风,在遗传免疫发病的机制进行了探索。
