ABSTRACT
Objective:
To investigate the expression of Plk1 ( Polo-like kinase 1 ) and Chk1/2 ( Checkpoint kinase 1/2 ) in primary hepatic carcinoma tissue and HepG2 cell.Methods:
Using immunohistochemistry chemical method detected expression of Plk1,Chk1/2 protein in 40 cases of primary hepatic carcinoma tissue and 16 cases of non-tumor tissue of liver. Western blot was applied to detect the expression of Plk1 and Chk1/2 protein in HepG2 cells, and gray value was measured by using the quantitative analysis.Results:
The positive rate of Plk1,Chk1/2 protein expression in primary hepatic carcinoma was 57. 5%,75. 0% and 22. 5%respectively,compared with positive rate in the liver of non-tumor tissue were 0%,25. 0% and 56. 3%. The expression of Plk1 and Chk1 protein in primary hepatic carcinoma tissue is higher than that in non-tumor tissue of liver,and the difference was statistically sig-nificant( PChk1>Chk2.Conclusion:
Plk1,Chk1 protein in primary hepatic carcinoma was up-regulated,while Chk2 protein was down-regulated in these tissues. The expression degree was Plk1> Chk1>Chk2. There were relatively selective expression in primary hepatic carcinoma tissue of Plk1,Chk1 protein,then Plk1 and Chk1 might be ideal targets for therapy of primary hepatic carcinoma.
