Meanwhile, in TCGA-GBM, it can be found that the expression levels of NR2F2AS1 and HOTAIRM1 were significantly higher than that of normal tissues (Figures 8F,G), and the high expression levels were significantly correlated with poor prognosis in TCGA-GBM database (Figures 8H,I). Here, HOTAIRM1 is linked to glioblastoma.
