GLI1 and glioblastoma: Cox regression analysis also revealed that GLI expression was associated with the overall survival of patients with glioblastoma from the CGGA mRNA and RNA sequencing datasets (P = 0.019, HR = 1.588, 95% CI = 1.080–2.334; P = 0.032, HR = 1.687, 95% CI = 1.045–2.725, respectively).
