BACKGROUND: Annexin A5 (ANXA5) is a kind of Ca2+-dependent phospholipid binding protein which is involved in cell membrane dynamics and organization. Recent data showed that ANXA5 might involve in tumorigenesis. OBJECTIVE: To explore what role ANXA5 play in human uterine cervical carcinoma. MATERIALS AND METHODS: In this study, a recombined ANXA5 plasmid was constructed and uterine cervical carcinoma cell lines HeLa and SiHa were transfected with it. After ANXA5 overexpression was determined by Western Blot, cell proliferation test was detected by MTT assay and colony formation assay respectively. FACS assay and Hochest33258 staining methods were employed to detect cell apoptosis. To further investigate whether ANXA5 influence cell migration and invasion, wound healing assay and transwell assay were applied. At the same time, the relative mechanism was investigated. RESULTS: When ANXA5 expression increased, cell proliferation was inhibited by regulating the expression of bcl-2 and bax while cell metastasis was suppressed by regulating E-cadherin and MMP-9 expression. CONCLUSION: ANXA5 overexpression in the uterine cervical carcinoma might play important roles in cell proliferation and metastasis of uterine cervical cancer cells and act as an anti-cancer gene in uterine cervical cancer.
