In comparison to the healthy tissues, VISTA was expressed at obviously higher levels only in cholangiocarcinoma (CHOL), glioblastoma multiforme (GBM), kidney renal clear cell carcinoma (KIRC), acute myeloid leukemia (LAML), brain lower grade glioma (LGG), and pancreatic adenocarcinoma (PAAD) (Fig. 3). Here, VSIR is linked to glioblastoma.
