Sox15, Ftz-f1, and CG15784 contribute to YAP/Yki + dTcf/PanRNAi tumor formation. (A) Confocal micrographs of ap-Gal4, UAS-GFP, UAS-Yki, UAS-dTcf/PanRNAi tumorous disk (Left), expressing of Ftz-f1RNAi, Sox15RNAi, CG15784RNAi as indicated in the figure (panels on the Right). (B) Confocal micrographs of ap-Gal4, UAS-GFP, UAS-Yki wing imaginal disk (Left) expressing α-Ftz-f1, β-Ftz-f1, Sox15, CG15784 as indicated in the figure (panels on the Right). GFP is shown in green. Nuclei are labeled with DAPI (blue). All of the images were taken under the same magnification (Scale bars, 100 μm). (C) Tissue-size quantification of wing imaginal discs in A (Unpaired t test, n = 12, 18, 17, 17, 12, 18 from left to right, ****P < 0.0001). (D) Tissue-size quantification of wing imaginal discs in B (Unpaired t test, n = 12, 18, 8, 9, 7, 24 from left to right, ****P < 0.0001).
