CDK8 and β-catenin mRNA expression in colon tumor and adjacent normal tissues detected by real-time PCR. Fresh tumor and corresponding adjacent tissues from 12 patients were resected under sterile conditions and then snapfrozen in liquid nitrogen immediately. 200 mg tissue was taken out from liquid nitrogen and plused 1 ml Trizol when RNA was extaracted. Real-time PCR is performed for the expression levels of CDK8 (A) and β-catenin (B). Results are given as means ± SD from three independent experiments. P < 0.05.
