Abstract

Objective To investigate the expression of sex determining region Y box protein 4(SOX4) gene and its biological effects in endometrial carcinoma. Methods 156 cases of endometrial carcinoma tissues, adjacent tissues of endometrial carcinoma and 156 cases of endometrial atypical hyperplasia were collected; Immunohistochemistry was used to detect the expression of SOX4 in endometrial cancer, endometrial dysplasia and normal endometrial tissue, and to analyze the relationship between SOX4 and the clinical characteristics of patients with endometrial cancer. After establishing the SOX4 overexpression/silencing Ishikawa cell strain using the lentivirus transfection technique, MTT, flow cytometry and Transwell chamber method were used to detect the cell proliferation, apoptosis, migration and invasion ability, and Western blotting method was used to detect SOX4, βcatenin and E-cadherin protein expression changes. Results The expression of SOX4 in endometrial cancer tissue was higher than that in normal endometrial tissue and endometrial atypical hyperplasia (P<0.05). SOX4 expression was correlated with invasion depth, International Federation of Obstetrics and Gynecoogy(FIGO) stage and lymph node metastasis (P<0.05). Compared with control group, SOX4 overexpressed Ishikawa cells have significantly increased proliferative ability, migration and invasion ability, significantly reduced apoptosis rate, significantly increased SOX4 and β-catenin protein expression, and significantly reduced E-cadherin protein expression (all P<0.05). while the proliferation ability, migration and invasion ability of Ishikawa cells interfered by SOX4 were significantly reduced, the apoptosis rate was significantly increased, the expression of SOX4 and β-catenin protein was significantly reduced, and the expression of E-cadherin protein was significantly increased (all P<0.05). Conclusion SOX4 gene is highly expressed in endometrial cancer tissues, which may promote the development of endometrial cancer by activating Wnt/β-catenin signaling pathway.
