In pediatric ependymoma, a malignant glial cell tumor, high expression of the microRNA, miR-124-3p, and low expression of one of its target genes, TP53INP1, correlated with shorter progression-free survival, suggesting the potential to target miR-124-3p and TP53INP1 in new therapeutic approaches for this cancer (Margolin-Miller et al., 2017). The gene discussed is TP53INP1; the disease is malignant glioma.
