C. Viability of CAL27 cell line transfected with si-GFP or si-p53 oligos and empty vector or GFP-YAP construct, as indicated in the legend to the graph.Cell viability analysis in A and B was determined by trypan blue dye exclusion staining, in C was determined by ATPlite luminescence analysis. All the values are means + s.d. of six replicates from three independent experiments.
