正常情况下,当炎性反应缓解后,该转化作用就会停止,但是在炎性反应持续活化的情况下,EMT过程将会持续存在,最终导致器官纤维化。在该过程中,许多因素通过复杂的通路引起EMT。目前研究最多的是TGF-β/smad通路,整合素连接激酶(ILK)和Wnt/β-catenin 通路。举例:TGF-β在肝纤维化中的研究肝纤维化主要指肝脏由...
EMT主要包括了三种类型 I型: 原肠胚时期,原始的上皮细胞发生EMT,参与多细胞生物胚胎发育和器官形成肠胚发生过程的EMT和Wnt信号通路有关,如果缺少Wnt3,则不能进行原肠胚形成相关的EMT。TGF-β家族成员(尤其是Nodal,Vg1)介导了Wnt信号通路,它们的缺失会引起功能性EMT缺失。从而影响胚胎组织发育。 II型: 内皮或者是...
PTBP3 is indispensable to TGF-beta-induced EMT and metastasis of LUAD cells and is a novel potential therapeutic target for the treatment of LUAD.Dong, ChenglaiWu, KaiqinGu, ShaoruiWang, WenliXie, ShiliangZhou, YongxinCell cycle
TGF-β信号传导的失调与多种疾病的发展有关,例如血液系统恶性肿瘤,例如白血病、血液性毛细血管扩张、软骨发育不良、伤口愈合不良、神经退行性疾病、发育障碍和肺动脉高压等。TGF-β信号传导的遗传性或表观遗传性丢失,会通过抑制免疫系统和上皮肿瘤细胞的细胞分化变化来促进肿瘤发生,这种现象称为EMT(Epithelial Mesenchymal ...
在体内,我们还发现USP4敲低明显阻断了HCC细胞的转移。从机理上讲,我们发现USP4直接与I型TGF-beta受体(TGFR-1)相互作用并去泛素化以激活TGF-β信号通路,并随后在HCC细胞中诱导上皮-间质转化(EMT)。综上所述,我们的结果阐明了USP4在HCC中高表达并促进了肿瘤的侵袭和转移,其潜在机制是USP4直接与TGFR-1相互...
Recently, it was demonstrated that transforming growth factor (TGF)-beta induces EMT in alveolar epithelial cells (AEC) in vitro and in vivo, and epithelial and mesenchymal markers have been colocalized to hyperplastic type II (AT2) cells in lung tissue from patients with idiopathic pulmonary ...
TGF-beta-induced EMT was blocked by RNA silencing of HEY1 or JAG1, and by chemical inactivation of Notch. The EMT phenotype, biphasic activation of Hey1, and delayed expression of Jag1 were induced by TGF-beta in wild-type, but not in Smad3-deficient, primary mouse kidney tubular ...
《AMPK对TGFbeta信号转导和乳腺癌转移的抑制作用》是依托南昌大学,由罗志军担任项目负责人的面上项目。项目摘要 乳腺癌在女性癌症患者位居第一,死亡率居第二。死亡的主要原因是晚期转移。癌细胞在发生上皮细胞至间充质细胞转化(EMT)、获得干细胞CSC特性后,发生侵润、转移,在远位第二次生长, TGFbeta被证明在...
