miR-380-5p represses p53 to control cellular survival and is associated with poor outcome in MYCN amplified neuroblastoma

The characterization of miR-380-5p–driven p53 repression provides a new mechanism for downmodulation of stress-induced antiproliferative responses in wild-type p53 contexts, including embryonic stem cells and neuroblastoma tumors. miR-380-5p potentiates Ras-induced mammary gland tumorigenesis and is frequently elevated in human neuroblastomas. miR-380-5p inactivation induces tumor cell death and shows therapeutic efficacy in orthotopic neuroblastoma models.
