As shown in Table 3, the abnormal expression of TAZ, nuclear β-catenin, membranous β-catenin, TAZ & nuclear β-catenin and TAZ & membranous β-catenin were markedly correlated with lymph node metastasis, invasion of serosa and tumour differentiation (P < 0.05, respectively). The gene discussed is WWTR1; the disease is neoplasm.
