The mRNA expression level of BTG2 in tissues of UCEC, LUAD, ESCA, STES, KIRP, KIPAN, COAD, COADREAD, PRAD, STAD, HNSC, KIRC, LUSC, WT, SKCM, BLCA, PAAD, OV, UCS, PCPG, ACC, KICH was significantly different from that in normal tissues, and the mRNA expression level in tumor tissues was lower than that in normal tissues (Figure 3A). This evidence concerns the gene BTG2 and neoplasm.
