目的
2
探讨FERMT1在肺腺癌细胞中的表达情况,研究FERMT1调控Wnt信号通对肺腺癌细胞增殖、侵袭、迁移、凋亡的影响及其机制。
方法
2
本研究利用生物信息学分析了FERMT1在肺腺癌中的表达及其与患者临床特征和预后的关系;并采用体外实验研究FERMT1对肺腺癌生物学行为的作用,使用实时荧光定量聚合酶链反应(quantitative real-time polymerase chain reaction,qRT-PCR)和蛋白质印迹技术(Western blot)方法检测分析FERMT1表达水平的变化对Wnt/β连环蛋白(β-catenin)通路及其下游靶基因的影响。
结果
2
生物信息学分析显示FERMT1在肺腺癌组织中高表达,肺腺癌TNM分期中Ⅰ~ Ⅳ期FERMT1的表达水平均高于正常肺组织,同时,FERMT1的高表达导致肺腺癌患者的不良预后,Wnt信号通路是其主要通路。体外实验显示,抑制FERMT1的表达降低肺腺癌细胞的增殖、迁移和侵袭能力,增加肺腺癌细胞的凋亡。qRT-PCR和Western blot结果显示,FERMT1表达的变化影响β-catenin、上皮间质转化(epithelial-mesenchymal transition,EMT)相关标志物及其下游靶基因的表达。
结论
2
FERMT1与肺腺癌发生发展密切相关,Wnt/β-catenin信号通路是其作用的机制之一。
Objective
2
To investigate the expression of FERMT1 in lung adenocarcinoma cells and the effect and mechanism of FERMT1 on the proliferation,invasion,migration,and apoptosis of lung adenocarcinoma cells by regulating the Wnt signaling pathway.
Methods
2
The bioinformatics analysis was used to investigate the expression of FERMT1 in lung adenocarcinoma and its association with clinical features and prognosis;
in vitro
experiments were used to investigate the influence of FERMT1 on the biological behavior of lung adenocarcinoma;qRT-PCR and Western blot were used to observe the effect of the change in FERMT1 expression on the Wnt/β-catenin pathway and its downstream target genes.
Results
2
The bioinformatics analysis showed the high expression of FERMT1 in lung adenocarcinoma tissue,the expression level of FERMT1 in TNM staging of lung adenocarcinoma was higher than that in normal lung tissue,and meanwhile,the high expression of FERMT1 led to the poor prognosis of lung adenocarcinoma patients,mainly through the Wnt signaling pathway.
In vitro
experiments showed that inhibition of FERMT1 expression reduced the proliferation,migration,and invasion abilities of lung adenocarcinoma cells and increased the apoptosis of lung adenocarcinoma cells. The results of qRT-PCR and Western blot showed that the change in FERMT1 expression affected the expression of β-catenin,epithelial-mesenchymal transition-related markers,and their downstream target g
enes.
Conclusion
2
FERMT1 is closely associated with the development and progression of lung adenocarcinoma through the Wnt/β-catenin signaling pathway.
