ABSTRACT
Objective To examine DNMT1,?-catenin and P-GSK-3? expressions in tissues of colon carcinoma compared with tumor clinicopathological parameters including differentiation and metastasis.Methods SYBR Green real-time PCR and immunoblotting method were used to detect these gene expressions in 62 tissues of colon carcinoma and 21 tissues of normal colon.Results Overexpressions of DNMT1,?-catenin,and P-GSK-3? were found in colon carcinoma tissues.The expression of DNMT1 was found to be higher in poorly differentiated tissues.The results also demonstrated statistical significance in the expression of ?-catenin involving differentiation and metastasis,but no statistical significance in the expression of P-GSK-3?.Conclusion These results show that DNMT1,?-catenin and P-GSK-3? expressions are regulated throughout colon cancer progression.
