Figure Lengend Snippet: ( a ) MDCK type I cells harbouring Src-EGFP were mixed with wild-type cells at a ratio of 35:1 and preincubated with the 100 μM S3i-201 (S3i), 20 μM stattic (Sta), 20 μM marimastat (Mari), or 400 nM ilomastat (Ilo) for 2 h and then incubated with Dox for 24 h. ( b ) Two type I clones harbouring Src-EGFP and STAT3-Y705F (DN) were mixed with wild-type cells at a ratio of 35:1 and incubated with Dox for 24 h. Cell behaviour was assessed by using the criteria . ( c, d ) Type I cells harbouring Src-EGFP were mixed with wild-type cells at a ratio of 10:1 and incubated with Dox for 24 h. Wild-type and Src-EGFP harbouring cells were separately incubated with Dox for 24 h, and cell lysates were mix at a ratio of 10:1. These cell lysates were subjected to immunoblotting analysis using the indicated antibodies. Relative intensity of p-Src (pY418)/GFP, p-STAT3 (pY705)/STAT3, and pY1000/Gapdh were calculated by setting the value for lysate mix to one. ( e, f ) Type I and II harbouring Src-EGFP were incubated in the presence of Dox for indicated time periods. Lysate from these cells were analysed by immunoblotting using indicated antibodies. Relative ratio of p-Src/GFP, p-STAT3/STAT3, and pY1000/Gapdh were calculated by setting the value for 24 h-treated type I cells to one. The mean ratios ± SDs were obtained from three independent experiments. *, P < 0.05; **, P < 0.01; ***, P < 0.001; two-way ANOVA was calculated compared with the Dox-treated cells (a) or mock-transfected cells (b), and two-tailed t -test was calculated (d, f).
