| pubmed-article:16413100 | pubmed:abstractText | A dysregulated mitogen-activated protein kinase (MAPK) pathway plays an important role in various malignancies and is often mediated by mutations in several oncogenes (eg, RAF, RAS). B-RAF mutations, predominantly the specific V600E mutation and additional alterations in exons 11 and 15, were frequently detected in malignant melanomas, papillary thyroid tumors, and colorectal cancers with microsatellite instability (MSI). The present study investigated B-RAF mutations, MSI status, and activation of MAPK signaling in prostate tumors. | lld:pubmed |
