Abstract
- Objective: To establish the human colorectal cancer cell model SW620/PAR4D with inducible suppression of proteinase activated receptor 4 (PAR4) expression, and investigate the role PAR4 plays in the proliferation and migration of cancer cells.<br />Methods: A human colorectal cancer cell line with tetracycline-inducible expression regulatory system, namely SW620/Tet-on, was established; inducible expression lentiviral vector with artificial microRNA targeting PAR4, pLVX-Tight-Puro-PAR4-miR, was constructed and transfected into SW620/Tet-on to make an inducible PAR4-suppressed cell model SW620/PAR4D. Western blotting was used to confirm the suppression of PAR4 expression after the doxycycline (DOX) treatment. CCK-8 assay was used to evaluate the impact of suppressed PAR4 expression on cell proliferation, and wound-healing assay was used to analyze the migration of the cells.<br />Results: The SW620/PAR4D cell model was established successfully. Suppression of PAR4 expression by DOX treatment had no significant impact on the growth/proliferation of SW620/PAR4D cells, but markedly inhibited the cell migration.<br />Conclusion: Suppression of PAR4 expression has no significant effect on the proliferation of SW620 cells, but can inhibit the migration of the cells.
