MiR-205 Inhibits Neuroblastoma Growth by Targeting CAMP-Responsive Element-Binding Protein 1
Affiliations
Accumulating evidence indicates that microRNA-205 (miR-205) is involved in tumor initiation, development, and metastasis in various cancers. However, its functions in neuroblastoma (NB) remain largely unclear. Here we found that miR-205 was significantly downregulated in human NB tissue samples and cell lines. miR-205 expression was lower in poorly differentiated NB tissues and those of advanced International Neuroblastoma Staging System stage. In addition, restoration of miR-205 in NB cells suppressed proliferation, migration, and invasion and induced cell apoptosis in vitro, as well as impaired tumor growth in vivo. cAMP-responsive element-binding protein 1 () was identified as a direct target gene of miR-205. Expression of an miR-205 mimic in NB cells significantly diminished expression of CREB1 and the CREB1 targets BCL-2 and MMP9. CREB1 was also found to be upregulated in human NB tissues, its expression being inversely correlated with miR-205 expression ( = -0.554, = 0.003). Importantly, CREB1 upregulation partially rescued the inhibitory effects of miR-205 on NB cells. These findings suggest that miR-205 may function as a tumor suppressor in NB by targeting .
