MicroRNAs (MiRNAs) have been recognized to regulate cancer initiation and progression in carcinogenesis as either oncogenes or tumor suppressor genes, but their role in hypopharyngeal cancer development is not clearly defined. To determine whether miRNA-203 can promote tumor growth in human hypopharyngeal squamous cell carcinoma, we conducted experiments on the functional study of miRNA-203 and identification of miRNA-203 regulated target genes in hypopharyngeal cancer cells. We found that cell proliferation and cell colony-forming increased more in the miRNA-203 up-regulated cancer cells than in the negative control cancer cells. Up-regulation of miRNA-203 accelerated cell cycle progression in hypopharyngeal cancer cells. TP63 and B3GNT5 mRNAs were identified and validated as targets of miRNA-203. However, transwell assay and wound scratch assay showed that miRNA-203 did not involve in invasion and metastasis in hypopharyngeal cancer cells. According to the results, we conclude that miRNA-203 can promote tumor growth in human hypopharyngeal squamous cell carcinoma. These results provide the convincing evidence for the first time that up-regulation of miRNA-203 contributes to the malignancy of hypopharyngeal squamous cell carcinoma, possibly through down-regulating TP63 and B3GNT5.
