A study performed to identify prognostic lncRNAs using TCGA datasets reported that high expressions of five lncRNAs, that is, prostate androgen-regulated transcript 1 (PART1), MGC21881, myocardial infarction-associated transcript (MIAT), growth arrest specific 5 (GAS5) and Prader Willi/Angelman region RNA 5 (PAR5), were correlated with prolonged survival in glioblastomas [56]. This evidence concerns the gene GAS5 and glioblastoma.
