Dealing 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 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 کاملEGF and beta1 integrin convergently regulate migration of A431 carcinoma cell through MAP kinase activation.
We found that the convergently epidermal growth factor (EGF)-induced signal and the collagen-induced signal activate mitogen-activated protein kinase (MAPK), which induces migration. We examined the signaling mechanisms of EGF-induced cell migration on collagen using the A431 carcinoma cell. EGF (10 ng/ml) induced migration on collagen, but inhibited proliferation. Using a MAPK cascade inhibito...
متن کاملEscherichia coli LPS induces heat shock protein 25 in intestinal epithelial cells through MAP kinase activation.
Protection of colonic epithelial integrity and function is critical, because compromises in mucosal functions can lead to adverse and potentially life-threatening effects. The gut flora may contribute to this protection, in part, through the sustained induction of cytoprotective heat shock proteins (HSPs) in surface colonocytes. In this study, we investigated whether Escherichia coli LPS mediat...
متن کاملCytokine stimulation of energy expenditure through p38 MAP kinase activation of PPARgamma coactivator-1.
Cachexia is a chronic state of negative energy balance and muscle wasting that is a severe complication of cancer and chronic infection. While cytokines such as IL-1alpha, IL-1beta, and TNFalpha can mediate cachectic states, how these molecules affect energy expenditure is unknown. We show here that many cytokines activate the transcriptional PPAR gamma coactivator-1 (PGC-1) through phosphoryla...
