Thrombin, the terminal serine protease in the coagulation cascade, is a proinflammatory molecule in vivo and induces endothelial activation in vitro. The cellular signaling mechanisms involved in this function are unknown. The role of the p38 mitogen-activated protein kinase (MAPK) signaling pathway in thrombin-induced chemokine production was studied. Phosphorylation of both p38 MAPK and its s...
Li, Zhihe, Jing Ying Ma, Irene Kerr, Sarvajit Chakravarty, Sundeep Dugar, George Schreiner, and Andrew A. Protter. Selective inhibition of p38 MAPK improves cardiac function and reduces myocardial apoptosis in rat model of myocardial injury. Am J Physiol Heart Circ Physiol 291: H1972–H1977, 2006. First published June 2, 2006; doi:10.1152/ajpheart.00043.2006.—p38 MAPK is activated during heart d...
BACKGROUND/AIM Protein-bound polysaccharide-K (PSK) is extracted from Coriolus versicolor (CM101) and is clinically used in combination therapy for gastrointestinal cancer and small-cell lung carcinoma. We have previously demonstrated that PSK induces apoptosis and inhibites proliferation of promyelomonocytic leukemia HL-60 cells, but the signaling pathway for this action remains to be elucidat...
We investigated the involvement of mitogen-activated protein kinases (MAPKs) in the maturation of CD83(-) dendritic cells (DC) derived from human blood monocytes. Maturating agents such as LPS and TNF-alpha induced the phosphorylation of members of the three families of MAPK (extracellular signal-regulated kinase l/2, p46/54 c-Jun N-terminal kinase, and p38 MAPK). SB203580, an inhibitor of the ...
The present study aimed to investigate the expression and regulation of extracellular signal‑regulated kinase (ERK)1/2 and p38 mitogen‑activated protein kinase (MAPK) signaling pathways in periodontal tissue remodeling of orthodontic tooth movement. Sprague Dawley rats with orthodontic tooth movement were generated. After tension stress for 1, 3, 5, 7 and 14 days, the protein and mRNA expressio...
The effect of casticin was investigated by focusing on cell viability, apoptosis induction and cell cycle arrest in HL-60 cells. Casticin induced a dose- and time-dependent decrease in cell viability associated with apoptosis induction and G2/M cell cycle arrest. The addition of SB203580, an inhibitor for p38 mitogen-activated protein kinase (MAPK), but not SP600125 [c-Jun NH2-terminal protein ...
Activation of p38 mitogen-activated protein (MAP) kinase (MAPK) has been implicated in the mechanism of cardiomyocyte (CMC) protection and injury. The p38 MAPK controversy may be related to differential effects of this kinase on apoptosis and necrosis. We have hypothesized that p38 MAPK-mediated F-actin reorganization promotes apoptotic cell death, whereas it protects from osmotic stress-induce...
Mitogen-activated protein kinase (MAPK)-activated protein kinase 2 (MK2) is activated upon stress by p38 MAPK alpha and -beta, which bind to a basic docking motif in the C terminus of MK2 and which subsequently phosphorylate its regulatory sites. As a result of activation MK2 is exported from the nucleus to the cytoplasm and cotransports active p38 MAPK to this compartment. Here we show that th...
(1) Background: Sleep deprivation (SD) triggers a range of neuroinflammatory responses. Dexmedetomidine can improve sleep deprivation-induced anxiety by reducing response but the mechanism is unclear; (2) Methods: The model was established using an interference rod device. An open field test and elevated plus maze were used to detect emotional behavior mice. Mouse cortical tissues subjected RNA...
