Consistently, the public RNAseq data revealed (Figure 5B) that B3GNT5 mRNA levels were positively correlated with classical (AKT2, HES1, PDGFA, NES, EGFR, and NOTCH1) and mesenchymal (CASP1, CASP8, CHI3L1, CD44, TLR2, and TRADD) GBM markers, but negatively correlated with proneural (BCAN, ERBB3, DLL3, OLIG2, NKX2‐2, and SOX4) and neural GBM markers (SLC12A5, GABRB2, STY1, SNCG, NEFL, and MBP). The gene discussed is DLL3; the disease is glioblastoma.
