Except for lymphoma, brain and central nervous system cancer, and pancreatic cancer, the expression levels of the CLEC3B gene were significantly downregulated in all other available cancer tissues compared with normal tissues, including liver, bladder, breast, colorectal, cervical, esophageal, gastric, head and neck, lung, ovarian, prostate, and sarcoma tissues (Figure 1A). This evidence concerns the gene CLEC3B and central nervous system cancer.
