Apart for the fact that we needed a fully compatible model to link and overlap our results with what we previously validated on HuR and hypoxia, we persistently uncovered dysregulated meningioma signature genes, such as CDKN1A, HIF1A, EGFR, MUC1 (EMA), NRAS, MMP2, STAT3, ETV6, MN1, ERCC2, MDM2, NF2 and TP53, some of them well known to be often associated together in meningioma. This evidence concerns the gene HIF1A and meningioma.
