摘要:
目的:探讨鼻咽癌干细胞的生物学行为和Ras信号通路特征,以及CD44与Ras信号通路活化之间的调控关系。方法:采用无血清悬浮培养法获得鼻咽癌CNE2和5-8F细胞的干细胞CNE2-SC和5-8F-SC。采用细胞计数试剂盒8(CCK-8)法检测细胞增殖,细胞平板克隆形成实验观察细胞克隆形成情况,Transwell细胞迁移实验检测细胞的迁移能力,细胞黏附实验观察细胞贴壁情况,Western blot法检测细胞中Ras信号通路相关蛋白的表达水平,采用RNA干扰技术明确CD44对Ras信号通路的调控作用。结果:接种后24、48和72 h,鼻咽癌干细胞CNE2-SC和5-8F-SC的增殖能力分别低于其来源鼻咽癌细胞(均 P
摘要(英文):
Objective:To study the biological behavior of nasopharyngeal carcinoma stem cells and to explore the activation of Ras signaling pathway regulated by CD44.Methods:CNE2-SC and 5-8F-SC were nasopharyngeal carcinoma stem cells and obtained by serum-free suspension culture. Cell counting kit-8 (CCK-8) assay, colony formation assay, Transwell migration assay, cell adhesion array were used to investigate the growth, proliferation, migration and adhesion of nasopharyngeal carcinoma stem cells. Western blot test was used to detect the expressions of Ra...
