The mitogen-activated protein (MAP) kinase / extracellular signal regulated kinase (ERK1/2) pathway regulates cell cycle progression, cellular growth, survival, differentiation, and senescence by responding to extracellular signals. Signal transduction happens by a cascade of kinase activity that requires the activation of RAS proteins which in turn activate the RAF household of kinases major towards the phosphorylation of your downstream mitogenactivated protein kinase kinase (MEK), and ultimately to the phosphorylation of extracellular signal regulated kinases (ERK1/2) which then phosphorylate lots of targets that elicit cellular changes, with effects on gene expression [1]. A high percentage of tumors exhibit constitutively higher ERK1/2 signaling, most frequently resulting from mutations in rat sarcoma (RAS) genes or the v-raf murine sarcoma viral oncogene homolog B1 (BRAF) gene [2]. Activating mutations inside the BRAF gene occur in around 50?0 of melanomas, 90 of which have a valine to glutamic acid substitution at position 600 (BRAFV600E), top to constitutively higher ERK1/2 activity [3, 4]. Constitutive activation with the ERK1/2 pathway alters gene expression to promote proliferation and metastasis [5]. Selective inhibition of oncogenic B.
