The OS analyses across TCGA datasets indicated that low ACAP1 levels correlated with shorter survival in patients with BLCA, BRCA, CESC, HNSC, LIHC, LUAD, OV, PAAD, PCPG, SARC, SKCM, STAD, THYM, UCEC, and UCS (Figure 4A–O) but more prolonged survival in patients with DLBC, GBM, KIRC, KIRP, LAML, and UVM (Figure 4P–U). Here, ACAP1 is linked to glioblastoma.
