upregulation of PDGF-DD-induced NK cell cytokine genes (芯片數(shù)據(jù))
downregulation of tumor cell-cycle genes
greater survival
TCGA GBM mRNA gene expression data obtained using the Affymetrix HT Human Genome U133a microarray platform (n = 539 patients)was downloaded through the UCSC data portal (https://) and matched to the gene expression data (Figures 4C and 4D). 7 of 9 cytokine genes (Figure 4C) and 27 of 34 cell cycle genes (Figure 4D) were matched with the GBM cohort.
