ACTR2 exhibited high expression in 28 tumor types (GBM, GBMLGG, LGG, UCEC, BRCA, CESC, LUAD, ESCA, STES, KIPAN, COAD, COADREAD, PRAD, STAD, HNSC, KIRC, LUSC, LIHC, WT, SKCM, BLCA, THCA, OV, PAAD, TGCT, UCS, LAML, CHOL), while low expression was observed in KIRP and KICH (Supplementary Figure 2A). This evidence concerns the gene ACTR2 and neoplasm.
