MYCN sustains a progenitor-stage differentiation block in human neuroepithelial stem cells to drive ETMR-like tumourigenesis [NanoString miRNA]
Listed in NCBI GEO
Embryonal tumours with multilayered rosettes (ETMRs) are aggressive paediatric brain tumours driven in most cases by amplification of the chromosome 19 microRNA cluster (C19MC), which upregulates the oncogene MYCN.
Description
Whether MYCN dysregulation alone is sufficient to produce ETMR-like tumours, independent of the broader C19MC machinery, has not been tested. Here, we show that sustained MYCN expression in human neuroepithelial stem (NES) cells, i.e. primitive neural progenitors resembling the proposed cell of origin of ETMR, is sufficient to generate ETMR-like brain tumours in vivo.
NanoString nCounter miRNA profiling was used to assess microRNA expression in this MYCN-only model, which lacks C19MC amplification.
