ABSTRACT
Objective To investigate the related factors of clinical stage and prognosis in the patients with endometrial carcinoma and their relation with proto-oncogene Wip1 expression level.Methods The paraffin samples of resected endometrial carcinoma in 120 cases of endometrial carcinoma in our hospital from January 2002 to January 2012 were collected as the experimental group,the samples were verified by pathology.Contemporaneous 120 samples of biopsy normal endometrial tissue served as the control group.The expression leve of Wipl were detected in turo groups.Results (1) In the Wip1 immunohistochemical staining results:Wip1 immunohistochemical staining was negative or weak in normal endometrial tissue cells,while showed pale yellow to yellowish-brown in endometrial cancer tissue.The positive expression rate of Wip1 protein in endometrial carcinoma tissue was 77.5%(93/120),which was higher than 22.5%(27/120) in normal endometrial tissue,the difference was statistically significant (P<0.05).(2)In the Western blot results of Wip1 protein in endometrial cancer tissue and normal endometrial tissue:the relative amount of Wip1 protein in endometrial carcinoma tissue was 0.635±0.023,which was significantly higher than 0.325±0.018 in normal endometrial tissue,the difference between the two groups was statistically significant (P<0.05).(3)In the real time quantitative qRT-PCR results of various samples:Wip1 mRNA expression level was higher than that in normal endometrial tissue,which were 0.628±0.053 and 0.191±0.009 respectively,the difference between the two groups was statistically significant(P<0.05).(4) The expression level of Wip1 had no correlation with age,estrogen and progesterone status,HER2,lymph node status and TNM stage,but had correlation with P53 expression level.Conclusion (1) The Wip1 expression amount is high in endometrial carcinoma and low in normal endometrial tissue.(2)The Wip1 expression level has no relation with age,estrogen and progesterone status,HER2,lymph node status and TNM stage,while has association with P53 expression level.
