In our study, the abnormal expression of TAZ, nuclear β-catenin, membranous β-catenin, TAZ & nuclear β-catenin and TAZ & membranous β-catenin were positively correlated with lymph node metastasis, invasion of serosa and tumour differentiation which are crucial histological features associated with poor prognosis, and these findings were consistent with previous results. The gene discussed is WWTR1; the disease is neoplasm.
