Objective:To investigate the association between Cyclin D1 and metastasis and determine the relationship between Cyclin D1 proteins expression and P21 WAF1?P53 proteins in ovarian cancer.Methods:Cyclin D1,P21 WAF1 and P53 proteins were detected from 61 ovarian carcinoma and 7 ovarian tissues without cancer by using Western blot method.Results:The positive rate of Cyclin D1 and P53 proteins expression in cases with ovarian cancer were significantly higher than those in without cancer tissues(P0.05).However, the expression of P21 WAF1 protein was correlated with clinical stages(P0.05).The expression of Cyclin D1,P53 and P21 WAF1 protein in ovarian carcinoma were related to metastasis(P
