Abstract:
Purpose To investigate the expression of TAZ and β-catenin in colorectal carcinoma and to analyze their correlation with the clinical pathological features of colorectal carcinoma. Methods The immunohistochemical method was used to detect the expres-sion of TAZ and β-catenin in 168 colorectal carcinoma specimens and 30 normal colorectal mucosal specimens. Results The positive rate of TAZ expression was significantly higher in colorectal carcinoma than that in normal colorectal mucosal (P<0. 01). The ectopic expression ofβ-catenin was significantly higher in colorectal carcinoma than that in normal colorectal mucosa (P<0. 01). The expres-sion of TAZ was correlated with degree of differentiation, lymph node metastasis, invasion depth and TNM stages (P<0. 05), and that of β-catenin was correlated with lymph node metastasis, invasion depth and TNM stages (P<0. 05). The positive expression of TAZ and the ectopic expression of β-catenin were significantly related to the 5-years survival rate ( P<0. 05 ) . The expression of TAZ was significantly positively correlated with the ectopic expression of β-catenin ( P<0. 01 ) . Conclusion Up-regulated expression of TAZ and ectopic expression of β-catenin may be synergistically involved in the occurrence, invasion and metastasis of colorectal carcinoma.
