Physical damage to the peripheral nerves triggers Schwann cell injury response in the distal nerves in an event termed Wallerian degeneration: the Schwann cells degrade their myelin sheaths and dedifferentiate, reverting to a phenotype that supports axon regeneration and nerve repair. The molecular mechanisms regulating Schwann cell plasticity in the PNS remain to be elucidated. Using both in v...
Although flavonoids exhibit a variety of beneficial biological activities, the exact molecular mechanism of the cellular effects is still not fully explained. In this study, we investigated the molecular mechanism of cytoprotective effect of eriodictyol in UV-irradiated keratinocytes. We found that treatment with eriodictyol effectively suppressed the UV-induced cell death of the keratinocytes,...
We previously demonstrated the protective effect of hydrogen sulfide (H2S) against doxorubicin (DOX)-induced cardiotoxicity through inhibition of endoplasmic reticulum stress. The aim of the present study was to explore the role of p38 mitogen-activated protein kinase (MAPK) in DOX-induced cardiotoxicity and ascertain whether exogenous H2S protect...
BACKGROUND There is a need for agents that suppress inflammation and progression of chronic obstructive pulmonary disease. p38 mitogen-activated protein kinase (p38 MAPK) has been associated with this disorder, and several inhibitors of this cascade are in clinical trials for its treatment, but their efficacy and utility are unknown. This study evaluated the relationship between p38 MAPK activa...
Atrial natriuretic peptide (ANP) has been shown to reduce tumor necrosis factor (TNF)-induced activation of endothelial cells via inhibition of p38 mitogen-activated protein kinase (MAPK) and nuclear factor (NF)B pathways. The aim of this study was to determine whether ANP is able to inhibit TNF-induced expression of monocyte chemoattractant protein-1 (MCP-1) in endothelial cells and to elucida...
BACKGROUND IL-24 (melanoma differentiation-associated gene-7 (mda-7)), a member of the IL-10 cytokine family, possesses the properties of a classical cytokine as well as tumor suppressor effects. The exact role of IL-24 in the immune system has not been defined but studies have indicated a role for IL-24 in inflammatory conditions such as psoriasis. The tumor suppressor effects of IL-24 include...
We previously reported that 15-lipoxygenase (15-LO) and its metabolite 15-hydroxyeicosatetraenoic acid (15-HETE) were up-regulated in pulmonary arterial cells from both pulmonary artery hypertension patients and hypoxic rats and that these factors mediated the progression of pulmonary hypertension (PH) by affecting the proliferation and apoptosis of pulmonary arterial (PA) cells. However, the u...
In solid organ transplantation, ischemia/reperfusion (IR) injury during organ procurement, storage and reperfusion is an unavoidable detrimental event for the graft, as it amplifies graft inflammation and rejection. Intracellular mitogen-activated protein kinase (MAPK) signaling pathways regulate inflammation and cell survival during IR injury. The four best-characterized MAPK subfamilies are t...
Delayed cytoprotection (preconditioning) occurs 24 h after sublethal simulated ischaemia and reperfusion (SI/R) in neonatal rat ventricular cardiomyocytes. SI/R was used to investigate the role of activation of mitogen-activated protein kinases (MAPKs), stress-activated protein kinases (SAPKs) and phosphoinositide 3-kinase-dependent protein kinase B (PKB)/Akt in cytoprotection. SI resulted in t...
Kaur, Jaswinder, Richard C. Woodman, and Paul Kubes. P38 MAPK: critical molecule in thrombin-induced NFB-dependent leukocyte recruitment. Am J Physiol Heart Circ Physiol 284: H1095–H1103, 2003. First published December 27, 2002; 10.1152/ajpheart.00016.2002.—Thrombin-stimulated endothelium synthesizes numerous adhesion molecules to recruit leukocytes; however, it is unknown which intracellular p...
