The results showed that MKI67 was significantly positively correlated with several of the pan-cancer immune checkpoint genes in some cancer types, such as THCA, STAD, LIHC, and BRCA, but also negatively correlated with the immune checkpoint genes in some cancer types, including THYM and GBM (Supplementary Figure S1C). This evidence concerns the gene MKI67 and glioblastoma.
