For instance, HOX transcript antisense intergenic RNA (HOTAIR) and HOXA Transcript Antisense RNA Myeloid-Specific 1 (HOTAIRM1), which are located in the HOXC and HOXA loci, respectively, are strongly expressed in GBM where they have pro-tumor functions [12,13,14,15,16,17]. The gene discussed is HOTAIRM1; the disease is glioblastoma.
