We investigated the proteogenomic reflection of the matrisome signature using transcriptomic and mass spectroscopy-based proteomic data from matched samples of GBM patients (CPTAC GBM database, N=86 after filtering out IDH-mutated and/or poor-quality samples based on pathology assessment) {Wang, 2021 #16}. This evidence concerns the gene IDH1 and glioblastoma.
