Expression of metastasis associated antigen 1 in endometrial carcinoma and its clinical significance / 解放军医学杂志

ABSTRACT

Objective To investigate the relationship between the expression of metastasis associated antigen 1 (MTA1) and the biological behavior of endometrial carcinoma. Methods From May 2005 to May 2007, 30 patients with endometrial carcinoma and 20 patients with normal endometrial tissues, were admitted to Changzheng Hospital of the Second Military Medical University for surgical treatment were involved in the present study. The expression of MAT1 mRNA in two different groups was detected by real-time RT-PCR, and of MAT1 protein was detected by immunohistochemical streptavidin-peroxidase (SP) method and Western blotting. The relationship between their expression and pathological features were analyzed. Results The positive expression rate of MTA1 protein was 80% in endometrial carcinoma group, which was significantly higher than that in control group (30%, P0.05). Conclusion The expression of MTA1 might play a potential role in the pathogenesis and development of endometrial carcinoma, and it might be a novel target for the therapy and prognostic indicator of endometrial carcinoma.
