We found that TCF3 was expressed at significantly higher levels in most cancers, especially in glioblastoma multiforme (GBM), breast invasive carcinoma (BRCA), colon adenocarcinoma (COAD), pancreatic adenocarcinoma (PAAD), acute lymphoblastic leukemia (ALL), acute myeloid leukemia (LAML), and cholangiocarcinoma (CHOL). The gene discussed is TCF3; the disease is glioblastoma.
