Programmed cell death 4 (PDCD4) is considered a tumor suppressor gene (3) and is frequently down-regulated in several types of cancers, such as lung cancers (4), pancreatic cancers (5), hepatocellular carcinomas (6), colon cancers (7), skin carcinomas (8), invasive ductal breast carcinomas (9), and gliomas (10). This evidence concerns the gene PDCD4 and glioma.
