Tumour samples had significant upregulation of GFAP (4.44-fold increase, mean LFC = 2.16 ± 0.26; p = 0.0002, 95% CI = 1.14 to 3.15), IDH1 (5.21-fold increase, LFC = 2.38 ± 0.15; p < 0.0001, 95% CI = 1.87 to 2.89), NANOG (4.06-fold increase, mean LFC = 2.02 ± 0.37; p < 0.0001, 95% CI = 1.13 to 2.91), SOX2 (3.42-fold increase, mean LFC = 1.77 ± 0.15; p < 0.0001, 95% CI = 1.09 to 2.45), SOX2-OT (14.47-fold increase, mean LFC = 3.86 ± 0.28; p < 0.0001, 95% CI = 3.26 to 4.45), and CD133 (3.01-fold increase, mean LFC = 1.59 ± 0.29; p < 0.0001, 95% CI = 0.89 to 2.30). This evidence concerns the gene GFAP and neoplasm.
