Objective:To investigate the expression and significance of guanine nucleotide exchange factor Dock180 in ovarian cancer
ovarian borderline tumor and ovarian benign tumor
and to evaluate their relationships with the initiation and progression of ovarian cancer.Methods:The expression of Dock180 protein was detected by immunostaining in 20 cases of ovarian benign tumor
12 cases of ovarian borderline tumor and 36 cases of ovarian cancer.Results:Immunostaining revealed that Dock180 protein was expressed in 66.7% of ovarian cancer
33.3% of ovarian borderline tumor and 15% of ovarian benign tumor(P<0.01).Conclusion:Over-expression of Dock180 may play an important role in the development of ovarian cancer and it could be used as a new measurement of malignant biological behavior of ovarian cancer.
