CRABP2 and bladder transitional cell carcinoma: However, in certain cancer types, such as ovarian cancer (OV), pheochromocytoma and paraganglioma (PCPG), pancreatic adenocarcinoma (PAAD), mesothelioma (MESO), glioblastoma multiforme (GBM), diffuse large B-cell lymphoma (DLBC), bladder urothelial carcinoma (BLCA), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), and adrenocortical carcinoma (ACC), especially in GBM, DLBC, and BLCA, there is no significant correlation between CRABP2 expression and most immune checkpoint genes.
