Disaccharides relative abundance. The relative abundance (%) for CS (A) and HS (B) disaccharides for proneural (PRO), mesenchymal (MES), and classical (CLA) GBM subtype, and control samples (left) and for GBM total (average of all subtypes) and control samples (right). For HS disaccharides %, relative abundance of N-acetylated (NA) versus N-sulfated (NS) is also provided for GBM subtypes and control (bottom left), and GBM total and control (bottom right) samples. Nomenclature for the Lawrence code are provided in supplemental Table S1 (∗p ≥ 0.05, ∗∗p ≥ 0.001, ∗∗∗p ≥ 0.0001, ∗∗∗∗p ≥ 0.00001) (mean ± SD). CS, chondroitin sulfate; GBM, glioblastoma; HS, heparan sulfate.
