Background/Objectives: miR-506-3p has been demonstrated to be a strong inducer of neuroblastoma cell differentiation, highlighting the potential of applying miR-506-3p mimics to neuroblastoma differentiation therapy. However, the target genes of miR-506-3p that mediate its differentiation-inducing function have not been fully defined. This study aims to comprehensively investigate the targetome of miR-506-3p regarding its role in regulating neuroblastoma cell differentiation. Methods: We combined gene expression profiling and functional high-content screening (HCS) to identify miR-506-3p target genes that have differentiation-modulating functions. For evaluating the potential clinical relevance of the identified genes, we analyzed the correlations of gene expressions with neuroblastoma patient survival. Results: We identified a group of 19 target genes with their knockdown significantly inducing cell differentiation, suggesting that these genes play a key role in mediating the differentiation-inducing activity of miR-506-3p. We observed significant correlations of higher mRNA levels with lower patient survival with 13 of the 19 genes, suggesting that overexpression of these 13 genes plays important roles in promoting neuroblastoma development by disrupting the cell differentiation pathways. Conclusions: Through this study, we identified novel target genes of miR-506-3p that function as strong modulators of neuroblastoma cell differentiation. Our findings represent a significant advancement in understanding the mechanisms by which miR-506-3p induces neuroblastoma cell differentiation. Future investigations of the identified 13 genes are needed to fully define their functions and mechanisms in controlling neuroblastoma cell differentiation, the understanding of which may reveal additional targets for developing novel differentiation therapeutic agents.
