Fig. 3: LncRNA SNHG17 knockdown repressed migration, invasion and EMT in PC9/GR and A549/GR cells.

A, B After transfection for 24 h, PC9/GR and A549/GR cells were subjected to migration and invasion analysis using a transwell assay. C Protein expression of E-cadherin, N-cadherin, Vimentin and Snail in PC9/GR and A549/GR cells were tested via western blot. D Immunofluorescence analysis of E-cadherin and N-cadherin in treated PC9/GR and A549/GR cells. Data were representative images or were expressed as the mean ± SD of n = 3 experiments. *P < 0.05, **P < 0.01, ***P < 0.001.
