Kaplan-Meier survival analysis revealed that participants with high expression levels of CUL7 had a shorter overall survival (OS) than those with low expression levels of CUL7 (63.51 vs 95.51 months, p < 0.001 in LGG, 11.73 vs 15.11 months, p < 0.05 in GBM) (Fig. 1f). Here, CUL7 is linked to glioblastoma.
