From: IGFBP3 induces PD-L1 expression to promote glioblastoma immune evasion
IGFBP3 positively correlates with PD-L1 expression in glioma patients. A The fraction of immune cells in the IGFBP3Low and IGFBP3High groups was assessed using CIBERSORT. B, C Correlation analysis of IGFBP3 and PD-L1 in TCGA (B) and CGGA (C) databases, left: LGG, right: GBM, and statistical significance was assessed using the spearman’s rank test. D, E Kaplan—Meier plots of IGFBP3 and PD-L1 gene expression in glioma patients from TCGA (D) and CGGA (E) databases, and statistical significance was assessed using the log-rank test
