HOTAIR enhanced the migration of RCC cells in vitro (A,B) HOTAIR expression in ACHN and A498 cells transduced with a HOTAIR-overexpressing (HOTAIR) or empty vector (EV), determined by real-time PCR. (C) HOTAIR expression levels in HOTAIR-targeted siRNA-transfected Caki-1 cells, determined by real-time PCR. (D,E, and F) Cell-proliferation CCK-8 assays in the indicated cell lines. (G,H, and I) Two-chamber assays using HOTAIR-overexpressing (G,H) or knockdown cells (I) in arbitrary units (a.u.). (J to L) Wound-healing assays. *P < 0.05, Mann-Whitney U test.
