The effect of miR-2277-3p and miR-26b-3p overexpression on proliferation, migration, and invasion of colon cancer cell line SW620. (a) 20 nM miR-2277-3p was transfected into SW620 cells, and the proliferation activity of SW620 cells were determined by cck-8 assay at the given time points; (b, c) 24 hours after transfecting 20 nM of miR-2277-3p into the SW620 cells, cell migration and invasion were determined by transwell assay; (d) 20 nM miR-26b-3p was transfected into SW620 cells, and the proliferation activity of SW620 cells were determined by cck-8 assay at the given time points; (e, f) 24 hours after transfecting 20 nM of miR-26b-3p into the SW620 cells, cell migration and invasion were determined by transwell assay; Data are the means ± SD. of three independent experiments. *P < 0.05 and ** P<0.01 versus control.
