The expressions of YAP1, β-catenin and survivin in colon cancer tissues and their clinical significance.

We aimed to evaluate the effects of YAP1, β-catenin, and survivin on the onset and progression of colon cancer, and to explore their correlations. The expressions of YAP1, β-catenin, and survivin in 106 colon cancer tissues and 55 normal colon mucosa tissues were measured by immunohistochemical assay. The correlations between their expressions and clinical and pathological characteristics were analyzed. The expression rates of YAP1, β-catenin, and survivin in colon cancer tissues were significantly higher than those in normal colon mucosa tissues (P<0.001). The expressions of YAP1, β-catenin, and survivin in colon cancer were correlated with neither gender nor age (P>0.05), but with the degree of differentiation, depth of invasion, lymph node metastasis and Duke's stage (P<0.05). Pearson's correlation analysis showed that the expressions of YAP1, β-catenin, and survivin in colon cancer tissues were all positively correlated (P<0.05). The overexpression of YAP1, β-catenin, and survivin played an important role in the onset and progression of colon cancer, providing reference value for prognosis prediction. IJCEP
