Background/Aims: MicroRNA (miRNA) plays important roles in the development of different cancers. In this study, we investigated the roles and mechanisms of miR-203 in human cervical cancer. Methods: miR-203 expression was detected in cervical cancer tumors and cell lines by qRT-PCR. The methylation status in the promoter region of miR-203 was examined by methylation-specific PCR. The functional effect of miR-203 was determined by both in vitro and in vivo assays. Results: miR-203 was frequently down-regulated in cervical cancer tumors and cell lines. This down-regulation of miR-203 was associated with methylation of the miR-203 promoter. Furthermore, miR-203 down-regulated vascular endothelial growth factor alpha (VEGFA) expression by directly targeting its 3'-untranslated region. Functional assays revealed that miR-203 suppressed cervical cancer cell proliferation, tumor growth, and angiogenesis in nude mice, whereas forced expression of VEGFA rescued this inhibitory effect. Conclusion: Our collective findings indicate that miR-203 functions as a tumor suppressor by targeting VEGFA, resulting in the inhibition of tumor growth and angiogenesis. Thus, miR-203 may be a potential therapeutic target and prognostic marker in cervical cancer.
