Analysis of reverse-phase protein array data (RPPA; a high-throughput antibody-based technique) from the TCGA GBM dataset yielded proteins significantly associated with TREM1, including IFGBP2, TGM2 VEGFR2, and NDRG1, many of which have also been linked to hypoxia (Figures 5B,G–I). This evidence concerns the gene NDRG1 and glioblastoma.
