上皮间质转化(E MT)是上皮细胞向间充质细胞分化的过程,EMT在恶性肿瘤的侵袭转移中广泛存在.EMT的发生与多种细胞因子、信号转导通路及转录因子有关,受多种影响因素的共同调控.上皮细胞表型的不同程度转化是细胞内外信号传递共同作用的结果.细胞外信号通过与细胞表面特异性受体相结合将信号转入细胞内,再通过胞内的信号转导途径,活化不同的核内转导因子,最终调节转导基因的表达.
上皮間質轉化(E MT)是上皮細胞嚮間充質細胞分化的過程,EMT在噁性腫瘤的侵襲轉移中廣汎存在.EMT的髮生與多種細胞因子、信號轉導通路及轉錄因子有關,受多種影響因素的共同調控.上皮細胞錶型的不同程度轉化是細胞內外信號傳遞共同作用的結果.細胞外信號通過與細胞錶麵特異性受體相結閤將信號轉入細胞內,再通過胞內的信號轉導途徑,活化不同的覈內轉導因子,最終調節轉導基因的錶達.

Epithelial-mesenchymal transition (EMT) is a differentiation process of epithelial cells into mesenchymals,which is widespread in the invasion and metastasis of malignant tumor.Studies show that EMT is influenced by a variety of factors such as cytokines,signaling pathways and transcription factors.Studies also show that intracellular and extracellular signal transmission could induce EMT.Signal transduction is a process which involves ligand-receptor binding in the extracellular,going into the cell and activating different nuclear transduction factor through intracellular signal transduction pathway.
