Abstract | OBJECTIVE: METHODS: A total of 110 paraffin colorectal sections were examined, which included 65 cases with UC, 25 cases with colorectal cancer and 25 cases with normal tissues. The expression of PTEN protein and AKT protein was detected with immunohistochemistry. RESULTS: (1) The patients with UC had lower expression of PTEN protein and higher expression of AKT than those with normal tissues (P < 0.01). (2) The patients with UC had higher expression of PTEN protein and lower expression of AKT protein than those with colorectal cancer (P < 0.01). (3) With the progress of UC, the expression of PTEN protein decreased while the expression of AKT protein increased (P < 0.01). (4) The expression of PTEN protein was negatively correlated with the expression with AKT protein in patients with UC and colorectal cancer (r = -0. 542 and -0. 674, respectively P < 0.01). CONCLUSION:
