Furthermore, scatter plots of epigenetically regulated DNA methylation-based stemness scores (EREG-METHss) (Figure 2B), differently methylated probe-based stemness scores (DMPss) (Figure 2C), enhancer elements/DNA amplification-based (ENHss) (Figure 2D), and epigenetically regulated RNA expression-based stemness scores (EREG-EXPss) (Figure 2F) revealed that FOXD3-AS1 was positively correlated with each stem cell index of GBM and LGG. Here, PTGDR is linked to glioblastoma.
