Abstract:
Objective To investigate the effects of TFF3 overexpression on the proliferation, migration, and invasion ability of colorectal cancer HT29 cells and the mechanisms involved in cancer metastasis. Methods HT29 cells were transfected with pIRES2-TFF3, and the expression levels of mRNAs and proteins related to TFF3 gene, TWIST1/TRIB3 signaling pathway, and epithelial-mesenchymal transition (EMT) were detected by qRT-PCR and Western blot. The proliferation, migration, and invasion ability of HT29 cells were detected by the CCK-8, cell scratch, and Transwell assays. Changes in cell morphology after TFF3 overexpression were observed through transmission electron microscopy. Results After the HT29 cells were transfected with pIRES2-TFF3, the expression levels of TFF3 mRNA and protein significantly increased (P<0.01); cell proliferation, migration, and invasion were significantly enhanced (P<0.01); and the expression of related genes, such as TWIST1, TRIB3, Vimentin, and Snail were significantly upregulated. By contrast, the expression of E-cadherin significantly decreased (P<0.05). Various changes in cell morphology were observed after TFF3 overexpression, such as decrease in cell junctions, loss of cilia, formation of pseudopodia, and increase in fusiform cells. Conclusion TFF3 overexpression may promote EMT in colorectal cancer cells through the Twist1/TRIB3 signaling pathway, increase their metastatic potential, and accelerate the malignant progression of colorectal cancer.
