Abstract

Objective To study the express of matrix metalloproteinase(MMP)-2 and tissue inhibitor of metalloproteinase(TIMP)-2 protein in human endometrial carcinoma. Methods The Immunohistochemistry was used to measure the MMP-2, TIMP-2 in endometrial carcinoma tissue of 40 patients, the atypical hyperplasia of 12 samples and the normal endometrium of 12 samples. Results The positive express of MMP-2 and TIMP-2 in the normal endometrium , atypical hyperplasia and endometrial carcinoma was increased gradually. In endometrial carcinoma, with progression of clinical stage and decrease of histological grade as well as deepening of cancer invasion, the ratio of MMP-2/TIMP-2 was increased. Conclusions The expression of MMP-2 and TIMP-2 were connected with endometrial carcinoma. The imbalance of MMP-2/TIMP-2 in the endometrial cancer might be one of the pathogenesis and development.
