Braf protein und hautkrebs das braf protein ist ein wichtiger bestandteil des ras raf mek erk mapk signalweges der am normalen wachstum und uberleben von zellen beteiligt ist.

Ras braf pathway. The mapkerk pathway also known as the ras raf mek erk pathway is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the dna in the nucleus of the cell. Various mutations in egfr ras and raf proteins can lead to particular t. Last year encouraging phase 3. Ras rat sarcoma ist ein proto onkogen das fur ein sogenanntes kleines g protein monomer codiert. Mutationen des braf proteins an der aminosaureposition 600 bewirken dass dieser signalweg uberaktiv wird. Ras and several of its downstream effectors including braf have been shown to be commonly mutated in a broad range of human cancers and biological studies have confirmed that ras pathway activation promotes tumour initiation progression and metastatic spread in many contexts.

The frequency of braf mutations varies widely in human cancers from more than 80 in melanomas and nevi to as little as 018 in other tumors such as 13 in lung cancers and 5 in colorectal cancer. Lesson on ras raf mek erk mapk pathway and its involvement in cancer pathogenesis. Rasrafmapk pathway is also involved in cell cycle regu lation wound healing and tissue repair integrin signaling and cell migration13 finally the rasrafmapk pathway is able to stimulate angiogenesis through changes in expression of genes directly involved in the formation of new blood ves. Braf is by far the most frequently altered gene in the mapk pathway downstream of ras altered in 7 to 10 of all cancers. Ras gtp ases are activated by the majority of growth factor receptors and bind and recruit raf to the cell membrane upon activation. Vemurafenib is an oral drug that inhibits the most common mutation of braf v600e found in about half of patients with metastatic melanoma.

More than 30 mutations of the braf gene associated with human cancers have been identified.
