The analysis revealed significant upregulation of ADM expression in tumor tissues compared to normal ones in certain cancer types, including glioblastoma multiforme (GBM), head and neck squamous cell carcinoma (HNSC), kidney chromophobe (KICH), kidney renal clear cell carcinoma (KIRC/ccRCC), acute myeloid leukemia (LAML), pancreatic adenocarcinoma (PAAD), pheochromocytoma and paraganglioma (PCPG), and testicular germ cell tumors (TGCT). This evidence concerns the gene ADM and glioblastoma.
