Ahmadov et al.93suggested that lncRNA HOTAIRM1 (HOXA transcript antisense RNA, myeloid‐specific 1) upregulated transglutaminase 2 (TGM2) by sponging miR‐17‐5p, thereby upregulating the viability and invasion ability of GBM cells and enhancing their radiotherapy resistance in vitro and in vivo. This evidence concerns the gene TGM2 and glioblastoma.
