HOTAIRM1 and glioblastoma: The number of candidate miRNAs with putative binding sites in HOTAIRM1 and any of the 12 candidate gene transcripts was further narrowed down by filtering for those miRNAs whose expression was inversely correlated to the expression of the 12 genes in the TCGA mRNA and miRNA glioblastoma data set (accession: phs000178.v10.p8.c1).
