We further evaluated the differences in the expression of CBX8 between the normal tissues and tumor tissues of uterine carcinoma (UCS), acute myeloid leukemia (LAML), ovarian serous cystadenocarcinoma (OV), lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), brain lower grade glioma (LGG), skin cutaneous melanoma (SKCM), testicular germ cell tumors (TGCT), and thymoma (THYM) (Figure 1B, all P-values < 0.01). This evidence concerns the gene CBX8 and thymoma.
