Involvement of ASK1 in Ca2+-induced p38 MAP kinase activation.
The mammalian mitogen-activated protein (MAP) kinase kinase kinase apoptosis signal-regulating kinase 1 (ASK1) is a pivotal component in cytokine- and stress-induced apoptosis. It also regulates cell differentiation and survival through p38 MAP kinase activation. Here we show that Ca2+ signalling regulates the ASK1-p38 MAP kinase cascade. Ca2+ influx evoked by membrane depolarization in primary...
متن کاملMAP kinase activation in macrophages.
Stimulation of macrophages by a variety of agents causes activation of mitogen-activated protein kinases (MAPKs). Activation of MAPKs by lipopolysaccharide involves CD14 and Toll receptors. Subsequent steps still remain to be explored. Tumor necrosis factor-alpha (TNF-alpha)-induced activation of MAPKs has been shown to involve the death domain proteins (TRADD, FADD, MADD) and TRAFs. Other mole...
متن کاملRHO-associated protein kinase alpha potentiates insulin-induced MAP kinase activation in Xenopus oocytes.
We recently identified Xenopus Rho-associated protein kinase alpha (xROKalpha) as a Xenopus insulin receptor substrate-1 binding protein and demonstrated that the non-catalytic carboxyl terminus of xROKalpha binds Xenopus insulin receptor substrate-1 and blocks insulin-induced MAP kinase activation and germinal vesicle breakdown in Xenopus oocytes. In the current study we further examined the r...
متن کاملDealing with osmostress through MAP kinase activation.
In response to changes in the extracellular environment, cells coordinate intracellular activities to maximize their probability of survival and proliferation. Eukaryotic cells, from yeast to mammals, transduce diverse extracellular stimuli through the cell by multiple mitogen-activated protein kinase (MAPK) cascades. Exposure of cells to increases in extracellular osmolarity results in rapid a...
متن کاملNonproteolytic microglial activation by tPA
The central nervous system (CNS) macrophages, the microglia, are the primary immune cells in the brain. Microglia secrete a variety of substances that contribute to both neuroprotection and neurotoxicity (Chao et al., 1995; Gebicke-Haerter et al., 1996; Zhang and Fedoroff, 1996), as well as to synaptic plasticity (Schoen and Kreutzberg, 1994). During neonatal development microglia display an am...
