Mitogen-activated protein kinase signal transduction in solid tumors.
Mitogen-activated protein kinase (MAPK) is an important signaling pathway in living beings in response to extracellular stimuli. There are 5 main subgroups manipulating by a set of sequential actions: ERK(ERK1/ ERK2), c-Jun N(JNK/SAPK), p38 MAPK(p38α, p38β, p38γ and p38δ), and ERK3/ ERK4/ ERK5. When stimulated, factors of upstream or downstream change, and by interacting with each other, these ...
متن کاملThe mitogen-activated protein kinase signal transduction pathway.
Catabolic processing of the amyloid precursor protein (APP) is subject to regulatory control by protein kinases. We hypothesized that this regulation involves sequential activation of the enzymes mitogen-activated protein kinase kinase (MEK) and extracellular signal-regulated protein kinase (ERK). In the present investigation, we provide evidence that MEK is critically involved in regulating AP...
متن کاملActivation of mitogen-activated protein kinase (mitogen-activated protein kinase/extracellular signal-regulated kinase) cascade by aldosterone.
Aldosterone in some tissues increases expression of the mRNA encoding the small monomeric G protein Ki-RasA. Renal A6 epithelial cells were used to determine whether induction of Ki-ras leads to concomitant increases in the total as well as active levels of Ki-RasA and whether this then leads to subsequent activation of its effector mitogen-activated protein kinase (MAPK/extracellular signal-re...
متن کاملGlycogen Synthase Kinase 3 Is a Natural Activator of Mitogen-activated Protein Kinase/Extracellular Signal-regulated
Glycogen synthase kinase 3 (GSK3 ) is implicated in many biological events, including embryonic development, cell differentiation, apoptosis, and insulin response. GSK3 has now been shown to induce activation of the mitogen-activated protein kinase kinase kinase MEKK1 and thereby to promote signaling by the stressactivated protein kinase pathway. GSK3 -binding protein blocked the activation of ...
متن کاملExtracellular signal regulated kinase (ERK)/mitogen activated protein kinase (MAPK)-independent functions of Raf kinases.
Raf comprises a family of three kinases, A-Raf, B-Raf and Raf-1, which are best known as key regulators of the MEK-MAPK/ERK cascade. This module is often perceived as a linear pathway in which ERK is the effector. However, recent advances have unveiled a role for Raf outside this established signalling unit. Current evidence, including gene-knockout studies in mice, suggests that there are ERK-...
