CDK8 and β-catenin protein expression in colon tumor and adjacent normal tissues detected by IHC. The expression of CDK8 (left) and β-catenin (right) was stained brown and present in tumor tissue and adjacent normal tissues. Representative sites with negative (a, 400 X ), moderate positive (c, 400 × ), strongly positive (e, 400 ×) expression of CDK8 and corresponding weakly positive (b, 400 ×), moderate positive (d, 400 ×), strongly positive (f, 400 ×) expression of β-catenin.
