GANT61 inhibits cell migration by attenuating the mesenchymal phenotype of HLE cells. (a) Transwell migration assay of HLE cells treated with 5 μM (GANT5) and 10 μM (GANT10) of GANT61. Migrated cells were stained with crystal violet. (b) The migration activity of the cells is expressed as a percentage of the cell number compared with the control. (c) Western blotting of E-cadherin, vimentin, and β-actin as an loading control. (d) Quantitarive PCR analysis of EMT-related transcription factors Snail1, Twist1, and Zeb1 in HLE (left) and HLF (right) cells treated with 10 μM GANT61. (e) Quantitative PCR analysis of Snail mRNA in HLE cells treated with control (si-Control) and Snail (si-Snail) siRNA. (f,g) Transwell migration assay of siRNA-treated HLE cells and their migration activity. * p < 0.05, ** p < 0.01 vs. vehicle control (DMSO).
