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.

| Summary: | 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. |
