INSR and central nervous system cancer: Functional enrichment of the full 98 DElncRNAs revealed over 30 significantly enriched pathways previously identified in glioma, including pathways associated with O-glycans (O-glycan biosynthesis, O-linked glycosylation of mucins, termination of O-glycan biosynthesis and HS-GAG degradation of glycoproteins), the Fanconi anemia pathway, the glutamate neurotransmitter release cycle, insulin receptor recycling, interaction between L1 and ankyrins as well as transferrin endocytosis and recycling (Supplementary file S1).
