SOX2 was differentially expressed in the following tumors: UCEC (C1 had the highest expression level; Figure 2A), PAAD (C3 had the highest expression level; Figure 2B), ovarian serous cystadenocarcinoma (C4 had the highest expression level; Figure 2C), LUSC (C3 had the lowest expression level; Figure 2D), LHC (C1 had the highest expression level; Figure 2E), ESCA (C6 had the lowest expression level; Figure 2F), COAD (C6 had the highest expression level; Figure 2G), BRCA (C6 had the lowest expression level; Figure 2H). This evidence concerns the gene SOX2 and ovarian serous cystadenocarcinoma.
