As depicted in Figure 2B, PDE2A levels were notably lower in adrenocortical carcinoma (ACC), acute myeloid leukemia (LAML), lower-grade glioma (LGG), ovarian serous cystadenocarcinoma (OV), testicular germ cell tumors (TGCT), and uterine carcinosarcoma (UCS) tissues relative to their corresponding normal tissues. The gene discussed is PDE2A; the disease is testicular germ cell tumor.
