摘要
目的探讨P62基因在恶性黑色素瘤A375细胞迁移、侵袭中的作用及其机制。方法取对数生长期的恶性黑色素瘤A375细胞,采用干扰P62基因表达的siRNA及阴性对照siRNA分别转染A375细胞。采用Transwell法检测干扰组及对照组的细胞迁移、侵袭能力,Western blotting检测干扰组及对照组Wnt/β-catenin信号通路的表达。结果干扰组细胞Transwell迁移、侵袭能力较对照组下降(P<0.05);且干扰组Wnt/β-catenin及下游通路因子(P62、ZEB1、β-catenin、TCF4、c-Myc、c-Jun及CCND1)均受抑制(P<0.05)。结论P62可能通过调控Wnt/β-catenin及下游通路促进黑色素瘤细胞的迁移、侵袭。
Objectives To explore the role and mechanism of P62 in malignant melanoma A375 cells invasion.Methods Malignant melanoma A375 cells were cultured at logarithmic growth phase,then they were transfected with siRNA-P62 and siNC,respectively.Transwell assays were both performed to detect the cell migration and invasion in interfering group and negative control group,respectively;Western Blot were both used to detect the expression of Wnt/β-catenin signaling pathways in two groups,respectively.Results The ability of cell migration and invasion decreased in interfering group compared with that in negative control group using Transwell(P<0.05),meanwhile,Wnt/β-catenin pathway and downstream factors(includingβ-catenin,TCF4,ZEB1,c-Myc,c-Jun,CCND1,and so on)were all inhibited in interfering gourp compared with that in negative control group(all P<0.05).Conclusions P62 may promote A375 cell migration and invasion via Wnt/β-catenin signaling pathways.
