Fig. 2: Knockdown of SNHG15 retards the aggressiveness of gefitinib-resistant LUAD cells.

a Transwell assay was conducted to examine the migration of A549/GR and H1975/GR. b Western blot was implemented to test the protein levels of EMT related proteins (E-cadherin, N-cadherin, Vimentin, ZEB1, and ZEB2) in A549/GR and H1975/GR. c Immunofluorescence assay was conducted to investigate EMT effect of A549/GR and H1975/GR. Data obtained from three replications were shown as mean ± S.D. **P < 0.01 indicated that differences were statistically significant.
