Mitogen activated protein kinases blockade improves lipopolysaccharide-induced ileal motor disturbances

Mitogen activated protein kinases blockade improves lipopolysaccharide-induced ileal motor disturbances.

BACKGROUND several diseases such as sepsis can affect the ileum. Lipopolysaccharide (LPS), an endotoxin present in the cell wall of gram negative bacteria, is a causative agent of sepsis. OBJECTIVES the aims of this study were: a) to investigate the role of mitogen activated protein kinases (MAPKs) in the effect of LPS on the acetylcholine-induced contractions of rabbit ileum; and b) to study...

Involvement of mitogen-activated protein kinases in adriamycin-induced cardiomyopathy.

The current study investigated the phosphorylation of mitogen-activated protein kinases (MAPKs) as well as pro- and anti-apoptotic proteins in adriamycin (ADR)-induced cardiomyopathy (AIC) and heart failure in rats. Modulatory effects of antioxidant probucol on the activation of MAPKs were also examined. Male rats were administered with ADR (15 mg/kg body wt ip, over 2 wk) with and without prob...

"Stress-responsive" mitogen-activated protein kinases (c-Jun N-terminal kinases and p38 mitogen-activated protein kinases) in the myocardium.

Mitogen-Activated Protein Kinase Cascades: Terminology and Properties The best-characterized subfamilies of the mitogen-activated protein kinase (MAPK) superfamily are the extracellularly responsive kinases (ERKs) and the two “stress-responsive” MAPK subfamilies, namely, the c-Jun N-terminal kinases (JNKs) and the p38-MAPKs. As yet, no single nomenclature has been determined, and the synonyms c...

Mitogen-activated protein kinases and retinal ischemia.

PURPOSE Mitogen-activated protein kinases (MAPKs), consisting of three major enzymes-extracellular signal-regulated kinase (ERK), p38, and c-jun N-terminal kinase (JNK)-couple cell-surface receptors to critical regulatory targets and gene transcription. We hypothesized that MAPKs are differentially expressed and have distinct functions after retinal ischemia. METHODS Rats were subjected to re...
