ADAMTS9 and glioblastoma: According to the correlation analysis among hypoxia score, the expression of hypoxia-related genes, and the six lncRNAs, we identified three key lncRNAs (ADAMTS9-AS2, LINC00968, and LUCAT1) that significantly affected the correlation between hypoxia score and the expression of hypoxia-related genes when eliminating three lncRNAs in both TCGA-GBM and CCGA-GBM datasets (Figure 8A).
