Quantification of the wound area invaded in 24 hours (grey dots) for Epi cells expressing CTR, HOT, HOTΔP or HOTΔP (B), or Mes cells transfected with ASO CTR (control), ASO1 and ASO2 targeting HOTAIR (C), or Epi cells overexpressing CTR or HOT alone or together with LSD1 (LSD1-OE) (D). Bars correspond to Mean values and Confidence Interval (CI) of 95%. *** P-value < 10-4, ** P-value < 0.03 (Student t-test, N=48 for (B), N=6 for (C), N=30 for (D)).
