Fig. 5. TUG1 regulates TWIST1 in CRC cell lines.
a The expression levels of TWIST1 in LoVo, HT-29, and HCT116 cells were detected by western blot following treatment with 3 ng/ml TGF-β or 2 μm LY 364947 for 48 h, *P < 0.05 and ***P < 0.001, versus control. b TWIST1 expression in LoVo, HT-29, and HCT116 cells transfected with NC-siRNA or TUG1 siRNA was analyzed by western blot, *P < 0.05, **P < 0.01, and ***P < 0.001, versus NC-siRNA. c, d Wound-healing assay (scale bar, 50 μm) and transwell invasion analysis (scale bar, 100 μm) of CRC cells transfected with TUG1 siRNA were transfected with NC-siRNA or TWIST1-siRNA.
