circPTK2 increases the migration and invasion capability of HCC cells. (A,B) Cell migration ability of HCC-LM3 and MHCC 97-H cells transfected with sh-circPTK2 plasmid(A), or OE-circPTK2 plasmid(B), assessed by scratch-healing assays; Mean ± SD, n = 3, **p < 0.01, ***p < 0.001, scale bar:100 μm. (C,D) The transwell assays without Matrigel evaluate the migration ability of HCC-LM3 and MHCC 97-H after circPTK2 knockdown(C) or overexpressing(D); Mean ± SD, n = 3, **p < 0.01, ***p < 0.001. (E,F) The invasion capability of HCC cells transfected with sh-circPTK2 plasmid(E), or OE-circPTK2 plasmid(F), was examined using transwell assays with Matrigel; Mean ± SD, n = 3, **p < 0.01, ***p < 0.001, vs. corresponding control plasmids.
