XIST and glioblastoma: Besides some well-known cancer-associated lncRNAs such as LINC01158 (Li Y. et al., 2018), LINC00461 (Dong et al., 2019), XIST (Yu et al., 2017), and HOTAIRM1 (Li Q. et al., 2018), we also identified several potential GBM progression-associated lncRNAs like POLR2J4, WWTR1-AS1, and VIM-AS1.
