SOX2 and glioma: Linc‐ROR acts as a sponge for miRNAs that target pluripotency regulators, and TUNA directly interacts with RNA‐binding proteins at the promoters of TFs, such as NANOG and SOX2, where transcription is activated by deposition of the active histone mark H3K4me3.43 Interestingly, the glioma tumour suppressor lincRNA‐p21 prevents somatic cell reprogramming by sustaining H3K9me3 and/or CpG methylation at pluripotency gene promoters or by direct association with SETDB1, a histone‐lysine N‐methyltransferase protein or DNMT1.80
