Extracellular signal-regulated kinase 2 is necessary for mesoderm differentiation.
The extracellular signal-regulated kinase (ERK) is a component of the mitogen-activated protein kinase cascade. Exon 2 of erk2 was deleted by homologous recombination and resulted in embryonic lethality at embryonic day 6.5. erk2 mutant embryos did not form mesoderm and showed increased apoptosis but comparable levels of BrdUrd incorporation, indicating a defect in differentiation. erk2 null em...
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 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 کاملUCN-01-Induced Cell Cycle Arrest Requires the Transcriptional Induction of p21 by Activation of Mitogen-Activated Protein/Extracellular Signal- Regulated Kinase Kinase/Extracellular Signal-Regulated Kinase Pathway
The small molecule UCN-01 is a cyclin-dependent kinase (CDK) modulator shown to have antiproliferative effects against several in vitro and in vivo cancer models currently being tested in human clinical trials. Although UCN-01 may inhibit several serine-threonine kinases, the exact mechanism by which it promotes cell cycle arrest is still unclear. We have reported previously that UCN-01 promote...
متن کاملActivation of the RAF/mitogen-activated protein/extracellular signal-regulated kinase kinase/extracellular signal-regulated kinase pathway mediates apoptosis induced by chelerythrine in osteosarcoma.
PURPOSE Chelerythrine, a widely used broad-range protein kinase C inhibitor, induces apoptosis in many cell types. In this study, the mechanism of chelerythrine-induced apoptosis in osteosarcoma was investigated. EXPERIMENTAL DESIGN Signaling pathways activated by chelerythrine in osteosarcoma were detected by Western blots. Impacts of RAF/mitogen-activated protein kinase (MAPK)/extracellular...
