( b ) A549_R and A549 cells were immunostained for Vimentin, beta -catenin and E-cadherin (green). Nuclei were counterstained with DAPI (blue). Scale bar, 25 mu m ( c-e ) mRNA levels of EMT-TFs and CDH2/N-cadherin in A549_R, H358_R and H460_R cells and the corresponding parental cells (A549, H358 and H460) were analyzed by qPCR. Data are shown as mean+-S.D. of three independent experiments ( n =3).

Experimental details: Figure 2 beta-catenin is related to ALDH HIGH activity cell population . (A,B) Density plots showing the percentage of ALDH HIGH cells in SiHa cell line grown in monolayer or spheres cultures. The bar graph showed the percentages of ALDH HIGH cells in monolayer (white bar) or spheres cultures (black bar). The enzymatic activity of ALDH was measured by flow cytometry using the ALDEFLUOR kit. The inhibitor DEAB was employed as a background fluorescence control (data not shown). Data was normalized with DEAB (internal control) from 3 independent experiments are showed in bar graph (Means +- S.E.M. ), * p < 0.05. (C) Western Blot of beta-catenin in SiHa cells transfected with siRNA scramble (negative control) or siRNA beta-catenin at 100 nM during 24 h. GAPDH was used as loading control. (D) The units were normalized with siRNA scramble and the densitometry quantification from 3 independent experiments are showed in bar graph (Means +- S.E.M), ** p < 0.01. (E,F) Density plots showing the percentage of ALDH HIGH cells obtained of spheres cultures from SiHa cells transfected with siRNA scramble (left panel) or siRNA beta-catenin (right panel). Transient transfection of SiHa cells using siRNA scramble (control) or siRNA beta-catenin was employed to knockdown beta-catenin. At 24 h post-transfection, SiHa cells were growth in spheres cultures for an additional 72 h. Each percentage of ALDH HIGH cells was normalized with DEAB as internal control.

Experimental details: Figure 4 GSK3-beta inhibition upregulates ALDH through beta-catenin-dependent transcriptional activity. (A) Images showing beta-catenin (green) localization in SiHa cells treated with DMSO (vehicle) or 5 muM of BIO obtained by immunofluorescence microscopy. The nuclei were stained with IP (red). Representative images from at least 3 independent experiments are showed. Magnification 40X. (B) Reporter activity of beta-catenin-dependent transcription in SiHa cells exposed to BIO treatment. Transient transfection of SiHa cells using the plasmid control pFOP (black bars) and the reporter plasmid pTOP (white bars) was employed to measure transcriptional activity of beta-catenin. At 24 h post-transfection, the SiHa cells were treated with BIO at the concentrations indicated for an additional 48 h. The values of luciferase were normalized to beta-galactosidase and the data are showed in bar graph from 5 independent experiments, (Means +- S.E.M). * p < 0.05, ** p < 0.01.
