Neuroblastoma is the most common extracranial solid tumor in children. We investigate whether miR-124, the abundant neuronal miRNA, plays a pivotal role in neuroblastoma. Knockdown of miR-124 promotes neuroblastoma SK-N-SH cell differentiation, cell cycle arrest and apoptosis. Further miR-124 is predicted to target aryl hydrocarbon receptor (AHR) which may promote neuroblastoma cell differentiation. We validate that miR-124 may suppress the expression of AHR by targeting its 3'-UTR. These results suggest that miR-124 could serve as a potential therapeutic target of neuroblastoma.
