摘要:近年研究发现,肿瘤细胞发生上皮向间质转化(EMT)摆脱细胞与细胞间连接而发生转移侵袭,已成为上皮细胞癌转移侵袭以及化疗耐药的一个重要途径。Snail家族成员,尤其是Snail被认为是肿瘤EMT发生的重要调节因子,它可以通过竞争性抑制E钙黏蛋白基因的表达,引起上皮细胞向间质细胞表型的转变,最终引起EMT。多项研究显示,在消化系统肿瘤中普遍存在EMT现象,并与这些肿瘤的侵袭转移及化疗耐药密切相关。

Abstract:Recent studies show that tumor cells get rid of the connections between cells, and induce tumor invasion and metastasis through epithelialmesenchymal transition (EMT). EMT becomes an important way to invasion, metastasis and chemotherapy resistance of epithelial cell carcinoma which accounting for more than 90% of malignant carcinomas. Members of Snail family, especially Snail is regarded as important adjustment factor of EMT, which induce the transformation from epithelial cell to mesenchymal phenotype through competitive inhibition Ecalcium protein gene expression. Many researches show that EMT exists widely in digestive system tumors, which is closly related to the invasion, metastasis and chemotherapy resistance of digestive system tumors.
