- Western blot analysis was performed on whole cell extracts (30 µg lysate) of MOLT-4 (Lane 1), U-87 MG (Lane 2), Caco-2 (Lane 3), U2OS (Lane 4), Jurkat (Lane 5) and HEK-293 (Lane 6). The blot was probed with anti-TCF7 Monoclonal Antibody (Product # MA5-14965,1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). A 50 kDa band corresponding to TCF7 was observed across the cell lines tested.

- Western blot was performed using Anti-TCF7 Monoclonal Antibody (C.725.7) (Product # MA5-14965) and a 50 kDa band corresponding to TCF7 was observed across across the cell lines and tissues tested. Whole cell extracts (30 µg lysate) of MOLT-4 (Lane 1), Jurkat (Lane 2), HeLa (Lane 3), SW480 (Lane 4), U-2 OS (Lane 5), LNCaP (Lane 6), Mouse Skeletal Muscle (Lane 7), Mouse Thymus (Lane 8) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177,1:20000 dilution) using the iBright™ FL1500 Imaging System (Product # A44115). Chemiluminescent detection was performed using SuperSignal™ West Atto Ultimate Sensitivity Substrate (Product # A38556).

- 10.1371/journal.pgen.1006990.g006 Fig 6 LEF1, TCF7 and Wnt3 are downregulated in Krt5-beta-catenin LOF CVP. To identify Wnt pathway genes regulated in the absence of beta-catenin, a Wnt pathway RT 2 profiler PCR assay was run on RNAs extracted from whole CVP of Krt5-beta-catenin LOF mice and their control counterparts (see Methods ). As expected, beta-catenin expression was downregulated 6 fold in Krt5-beta-catenin LOF mice compared with controls ( A ). Seven other genes were significantly regulated; all being downregulated ( A ) and attention was focused on genes which expression changed more than 2 fold, i . e . LEF1, TCF7 and Wnt3 ( A , genes in blue). Regulation of LEF1, TCF7 and Wnt3 expression was confirmed by qRT-PCR ( B ). qRT-PCR analysis of epithelium versus underlying tissue (mesenchyme and Von Ebner's glands) of wild-type CVPs revealed that LEF1 and Wnt3 are specifically expressed in the epithelium whereas expression of TCF7 is predominant in the epithelium and lower in the underlying tissue ( C ). Immunolabelling of LEF1 and TCF7 is localized in perigemmal basal cell, which include progenitors ( D , E , white arrowheads) and within taste buds ( D , E , yellow arrowheads). In addition, TCF7 signal was observed in the mesenchyme ( E , F , white arrows) supporting the qRT-PCR data. Dotted line delineates the basement membrane; Epi: CVP trench epithelium.

The same constructs as in ( a ) were cloned in the antisense direction between 2 anti-parallel asymmetric Lox66/Lox71 sites. Upon expression of Cre-recombinase the sequence is flipped in a unidirectional manner. c , d Western blot analysis showing expression of TCF7, SPI1, and NRAS for the different indicated constructs in Ba/F3 cells ( c ) ( n = 1) or Cre-Ba/F3 cells with active Cre-recombinase ( d ) ( n = 1). WT = Wild-type Ba/F3 and used as a control lysate. The viral P2A sequences within the expression vector results in a 3' in-frame 18 amino acid sequence tail on the first protein expressed accounting for the increased molecular weight for NRAS(G12D) and TCF7-SPI1 in ( c ) and ( d ), respectively. e Growth curve of Ba/F3 cells transduced with the vectors illustrated in ( a ) or empty vector (white). f Growth curve with floxed constructs illustrated in ( b ) in Ba/F3-Cre cells alongside an empty vector control. g - j Growth curves in pro-T cells after transduction with the indicated constructs and empty vector.
