Cells were washed in PBS, dissolved in 60‐100 μL solubilizing solution (9M urea, 2% NP40), and subjected to immunoblotting as previously described.3 (link) Primary Abs recognizing the following proteins were used: YAP1 (D8H1X), TAZ (v386), phospho‐(p)‐YAP1 (Ser127), p‐YAP1 (Ser397), p‐TAZ (S89), LATS1, and p‐LATS1 (Ser909) (all from Cell Signaling Technology), actin (Sigma), or GAPDH (Wako Chemical). Horseradish peroxidase‐conjugated anti‐rabbit Ab (Cell Signaling Technology) was used as the secondary Ab. Band intensities were determined by Fujifilm Multi Gauge software or the ImageJ program. The YAP1 and TAZ protein levels were normalized to actin or GAPDH, as indicated. Phosphorylated YAP1, p‐TAZ, and p‐LATS1 were normalized to total YAP1, TAZ, and LATS1 levels, respectively.
