For DLBC (lymphoid neoplasm diffuse large B-cell lymphoma), LAML (acute myeloid leukemia), OV (ovarian serous cystadenocarcinoma), and TGCT (testicular germ cell tumors), the KDM6B level decreased in the tumor tissues of DLBC, TGCT, and OV, while KDM6B expressed higher levels in the tumor tissues of LAML, all with p < 0.01 (Figure 1B). The gene discussed is KDM6B; the disease is ovarian serous cystadenocarcinoma.
