FERMT1 promotes epithelial-mesenchymal transition of hepatocellular carcinoma by activating EGFR/AKT/β-catenin and EGFR/ERK pathways
Objective
This study aimed to investigate the effects of fermitin family member 1 (FERMT1) on epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma (HCC) via the EGFR/AKT/β-catenin and EGFR/ERK pathways.
Methods
The expression of FERMT1 encoding protein kindlin-1 in HCC tissues was determined by immunohistochemistry, and FERMT1 mRNA expression in HCC tissues and cell lines was analyzed by qRT-PCR. After the FERMT1 expression of SNU182 and SNU387 interfered with siRNA, the cell viability, invasion, migration, and EMT were tested by CCK-8, transwell invasion, scratching, immunofluorescence/WB, respectively. Similarly, the effects of FERMT1 on the viability and metastasis of HCC were investigated in transplanted tumor and lung metastasis mouse models. The protein expressions of EGFR/AKT/β-catenin and EGFR/ERK pathways were analyzed by WB. In addition, the relationship between FERMT1 and EGFR was further determined by immunofluorescence double staining and Co-IP.
Results
FERMT1 was significantly upregulated in HCC, and silencing FERMT1 inhibited the viability, invasion, migration, and EMT of HCC. Silencing FERMT1 also inhibited the activation of EGFR/AKT/β-catenin and EGFR/ERK pathways. In addition, inhibition of EGFR, AKT, or ERK confirmed that EGFR/AKT/β-catenin and EGFR/ERK pathways were involved in the promoting effects of FERMT1 on HCC. Co-IP and immunofluorescence experiments confirmed the targeting relationship between FERMT1 and EGFR.
Conclusion
FERMT1 was highly expressed in HCC and promoted viability, invasion, migration, and EMT of HCC by targeting EGFR to activate the EGFR/AKT/β-catenin and EGFR/ERK pathways. Our study revealed the role of FERMT1 in HCC and suggested that FERMT1 exerts biological effects through activating the EGFR/AKT/β-catenin and EGFR/ERK pathways.
