Knocking down DST enhances YAP activity. (A) (Upper panels) Western blots on protein extracts from shLuc- or shDST-expressing MCF10A cells, blotted with anti-LATS1/2 (upper bands) or anti-GAPDH (lower bands). (Lower panels) Ratio of LATS1/2 levels between shLuc- and shDST-expressing MCF10A cells, normalized to GAPDH. Data are from three biological replicates. (B) Fold changes in CTGF or CYR61 or ITGB6 mRNA levels between shLuc- and shDST-expressing MCF10A cells. Data are from four biological replicates, performed in triplicates. (C) Fold changes in Luciferase activity between untreated MCF10A-shLuc cells and Tet-treated MCF10A-shDST cells, transfected with the YAP/TAZ-responsive MCAT-Luc reporter gene. Data are from three biological replicates, performed in triplicates. (D) (Left panels) Standard confocal sections of shLuc- or shDST-expressing MCF10A cells, stained with Phallodin (Magenta) to mark F-actin, anti-YAP (Yellow) and anti-Lamin (Blue) to mark the nuclear membrane. Scale bars represent 30 µm. (Right panel) quantifications of the percentage (%) of shLuc- or shDST-expressing MCF10A cells in which the ratio of YAP staining is higher in the nucleus than in the cytoplasm. Data are from three biological replicates. A total of 775 and 809 shLuc- and shDST-expressing cells, respectively, were quantified blind twice. (E) Fold changes in CTGF or CYR61 or ITGB6 mRNA levels in shLuc- or shDST-expressing MCF10A cells, treated with DMSO or Verteporfin (VP). Data are from three biological replicates, performed in triplicates. (F) Time course of growth rate for shLuc- or shDST-expressing MCF10A cells, before treatment (0 hours post-treatment) or treated with DMSO or VP for 24, 48 or 36 hours. A.U. Arbitrary Unit. Data are from three biological replicates. For all quantifications, error bars indicate SD.; ns indicates non-significant; *indicates P < 0.05; **indicates P < 0.005; ***indicates P < 0.001; ****indicates P < 0.0001.
