Sustained erk activation

SpletSustained ERK activation is a prominent abnormality in a large number of cancers. In addition to upstream signaling cascades, ERK is constitutively activated by genetic events, such mutation of BRAF kinase, an aberration most frequently observed in colorectal cancer and malignant melanoma ( Davies et al., 2002; Hodis et al., 2012 ). SpletA TrkA/EGFR chimera (TEE) also gave sustained responses to NGF activation. Furthermore, substoichiometric levels of a reversible EGFR kinase inhibitor made EGF-induced EGFR …
