Mitogen-activated protein kinase (MAPK) pathways transfer information from sensors to cellular responses in all eukaryotes. A surprisingly large number of genes encoding MAPK pathway components have been uncovered by analysing model plant genomes, suggesting that MAPK cascades are abundant players of signal transduction. Recent investigations have confirmed major roles of defined MAPK pathways ...
PI3K-Akt and Ras-MAPK pathways were both implicated in cell survival and neurite-outgrowth, respectively. Akt has been suggested to be involved in neuronal survival and MAPK in neurite outgrowth during development. This study investigated if Akt, a component of PI3K-Akt pathway, and MAPK/ERK, a component of Ras-MAPK pathway, were expressed in the normal and regenerating dorsal root ganglia and ...
Expression of endothelial nitric oxide synthase (eNOS) in transfected U-937 cells upregulates phorbol 12-myristate 13-acetate (PMA)-induced tumor necrosis factor-alpha (TNF-alpha) production through a superoxide (O(2)(-))-dependent mechanism. Because mitogen-activated protein kinases (MAPK) have been shown to participate in both reactive oxygen species signaling and TNF-alpha regulation, their ...
INTRODUCTION Pomegranate has been revered throughout history for its medicinal properties. p38-MAPK is a major signal-transducing pathway in osteoarthritis (OA) and its activation by interleukin-1β (IL-1β) plays a critical role in the expression and production of several mediators of cartilage catabolism in OA. In this study we determined the effect of a standardized pomegranate extract (PE) on...
p38 Mitogen-activated protein kinase (MAPK) is one of the most ancient signaling molecules and is involved in multiple cellular processes, including cell proliferation, cell growth, and cell death. In the heart, enhanced activation of p38 MAPK is associated with ischemia/reperfusion injury and the onset of heart failure. In the present study, we investigated the function of p38 MAPK in regulati...
Background: Since EGFR inhibitors show a limited therapeutic effect on Glioblastoma multiforme patients, the EGFR/MAPK/STAT5/FN14 signaling pathway becomes vulnerable to invasive GBM cell population and may be suitable target for treatment of GBM. Nanocurcumin consumption exercise training are probably effective interventions in this pathway. Objectives: This study aimed investigate simultaneou...
BACKGROUND AND PURPOSE It has been suggested that mitogen-activated protein kinase (MAPK) is involved in cerebral vasospasm after subarachnoid hemorrhage. The present study was undertaken to explore the inhibitory effect of U0126, a novel MAPK inhibitor, in the contraction of the rabbit basilar artery by 3 spasmogens: hemolysate, oxyhemoglobin, and bloody cerebrospinal fluid (CSF) from patients...
Mitogen-activated protein kinase (MAPK) signaling regulates fundamental cellular functions including proliferation, differentiation, and survival. We have demonstrated previously that inhibiting MAPK signaling induces apoptosis in melanoma cells but not in normal melanocytes, suggesting that the MAPK pathway propagates essential survival signals in melanoma cells. Here, we report that the 90-kD...
The loss of tumour suppressor gene function is a hallmark of malignant transformation and can occur by a variety of genetic and/or epigenetic alterations. We have previously characterised p38δ mitogen-activated protein kinase (MAPK) as a tumour suppressor in oesophageal squamous cell carcinoma (OESCC) and outlined how loss of p38δ MAPK expression promotes increased proliferation and migration, ...
The Mos protein kinase is a key regulator of vertebrate oocyte maturation. Oocyte-specific Mos protein expression is subject to translational control. In the frog Xenopus, the translation of Mos protein requires the progesterone-induced polyadenylation of the maternal Mos mRNA, which is present in the oocyte cytoplasm. Both the Xenopus p42 mitogen-activated protein kinase (MAPK) and maturation-...
