MicroRNA-1275 suppresses cell growth, and retards G1/S transition in human nasopharyngeal carcinoma by down-regulation of HOXB5.

ABSTRACT: Through analysis of a reported microarray-based high-throughput examination, we found that miR-1275 was significantly down-regulated in nasopharyngeal carcinoma (NPC). While its role and mechanism participated in NPC progression are still little known. Here, we explored the effect of miR-1275 on the progression of NPC. Results demonstrated that miR-1275 was markedly down-regulated in NPC tissues and cell lines. MiR-1275 markedly repressed cell growth as confirmed by CCK8 and colony formation assay, via inhibition of HOXB5 in NPC cell lines. Moreover, miR-1275 suppressed G1/S transition via inhibition of HOXB5. Further, oncogene HOXB5 was evidenced to be a potential target of miR-1275, and its expression was conversely correlated with miR-1275 expression in NPC. Collectively, our study indi
