Figure 2. CircZNF609 enhances invasion and migration of melanoma cells. (A–D) The A375 and SK-MEL-28 cells were treated with the circZNF609 shRNA or control shRNA. (A and B) The cell migration and invasion were tested by transwell assays in the cells. (C and D) The migration and invasion were analyzed by wound healing assays in the cells. The wound healing proportion was shown. Data are presented as mean ± SD. Statistic significant differences were indicated: *P < 0.05, **P < 0.01.
