Alcohol activates activator protein-1 and mitogen-activated protein kinases in rat pancreatic stellate cells.
Alcohol is a major cause of both acute and chronic pancreatitis. Activated pancreatic stellate cells (PSCs) have recently been implicated in the pathogenesis of pancreatic inflammation and fibrosis. Herein, we examined the effect of ethanol and acetaldehyde on the activation of transcription factors and mitogen-activated protein (MAP) kinases in PSCs. PSCs were isolated from rat pancreas tissue...
متن کاملMitogen-activated protein kinases and chemoresistance in pancreatic cancer cells.
BACKGROUND Chemoresistance is an important clinical problem in pancreatic cancer. As the mitogen-activated protein kinases (MAPKs) have been found to be involved in the development of chemoresistance in a variety of cancer cell lines, the aim of the current study was to assess the role and mechanism of MAPK signaling in mediating chemoresistance in pancreatic cancer cells. MATERIALS AND METHO...
متن کاملActivation of mitogen-activated protein kinases and activator protein-1 in myocardial infarction in rats.
OBJECTIVE The purpose of this study was to examine the activation of mitogen-activated protein kinases (MAPK) plus activator protein-1 (AP-1) and nuclear factor-kB (NF-kB) DNA binding activities, all of which seem to be important in a signal transduction cascade upstream of the increased level of mRNA expression observed after myocardial infarction. METHODS Myocardial infarction was produced ...
متن کاملAcute hypertension activates mitogen-activated protein kinases in arterial wall.
Mitogen-activated protein (MAP) kinases are rapidly activated in cells stimulated with various extracellular signals by dual phosphorylation of tyrosine and threonine residues. They are thought to play a pivotal role in transmitting transmembrane signals required for cell growth and differentiation. Herein we provide evidence that two distinct classes of MAP kinases, the extracellular signal-re...
متن کاملInhibition of p38 mitogen-activated protein kinase blocks activation of rat pancreatic stellate cells.
Activated pancreatic stellate cells (PSCs) have recently been implicated in the pathogenesis of pancreatic fibrosis and inflammation. However, the signal transduction pathways in PSCs remain largely unknown. We examined the role of p38 mitogen-activated protein (MAP) kinase in the activation of PSCs. PSCs were isolated from rat pancreas tissue and used in their culture-activated, myofibroblast-...
