The present study was designed to investigate the function of death-associated protein kinase 1 (DAPK1) in infantile pneumonia and explore potential mechanism actions. Male C57BL/6 mice were injected with 2 mg/kg LPS for model pneumonia. A549 cells treated 100 ng/ml vitro Dapk1 mRNA expressions 6, 12 or 24 h after induction mice. gene increased inflammation through activation p38MAPK-mediated N...

The p38 mitogen activated protein kinase (p38MAPK) pathway is an important signaling cascade involved in cell growth, differentiation and apoptosis. High glucose activates p38MAPK pathway in different cells, including osteoblasts. In the present study, role of p38MAPK in high glucose induced osteoblast apoptosis and potential of RNA interference (RNAi) targeting p38MAPK as a therapy strategy ha...

BACKGROUND/AIMS Previous studies have shown that p38MAPK is involved in gastric cancer, yet the underlying mechanism remains unclear. METHODS q-PCR, Western blot and immunohistochemistry were used to explore the expression of PP2A and the phosphorylation of p38MAPK in gastric cancer tissues and normal gastric tissues. Activated p38MAPK in the gastric cancer cell line MKN45 using activator, th...

Formation of new adipocytes from precursor cells contributes to adipose tissue expansion and obesity. In this study, we asked whether p38 mitogen-activated protein kinase (MAPK) pathway regulates normal and pathological adipogenesis. In both dietary and genetically (ob/ob) obese mice, adipose tissues displayed a marked decrease in p38MAPK activity compared with the same tissues from lean mice. ...

The p38 mitogen-activated protein kinase (p38MAPK) plays a key role in larval settlement of the barnacle Amphibalanus amphitrite. To study the signaling pathway associated with p38MAPK during larval settlement, we sought to identify the upstream kinase of p38MAPK. Three MKKs (MKK3, MKK4 and MKK7) and three MAPKs (p38MAPK, ERK and JNK) in A. amphitrite were cloned and recombinantly expressed in ...

Transforming growth factor beta (TGFbeta) contributes to tumor progression by inducing an epithelial to mesenchymal transdifferentiation (EMT) and cell migration. We found that TGFbeta-induced EMT was blocked by inhibiting activation of p38 mitogen-activated protein kinase (MAPK) with H-7, a protein kinase C inhibitor, and with SB202190, a direct inhibitor of p38MAPK. Inhibition of the p38MAPK ...

Tumor necrosis factor-alpha (TNFalpha) induces apoptosis and cell growth inhibition in primary rat fetal brown adipocytes. Here, we examine the role played by some members of the mitogen-activated protein kinase (MAPK) superfamily. TNFalpha activates extracellular regulated kinase-1/2 (ERK1/2) and p38MAPK. Inhibition of p38MAPK by either SB203580 or SB202190 highly reduces apoptosis induced by ...

Objective: To investigate the anti-depression mechanism of JiaWeiWenDan Decoction in regulating p38MAPK-ERK5 signal transduction pathway. Methods: Depression model rats were randomly divided into Blank Control Group, Model Chinese Medicine Treatment and Western Group (hereinafter referred to as Group), with 48 each group. The mice treated on 7th day, 14th day 21st respectively, for 28 days. key...

interleukin (il)-25, a cytokine of il-17 family, can activate p38 mitogen-activated protein kinases(mapk) and nuclear factor(nf)-κb pathways to propagate th2 responses. the allergic rhinitis mouse model was established by stimulating balb/c mouse with ovalbumin (ova). then we detected expression of il-25 and downstream p38mapk and nf-κb. the expression of il-25, p38mapk and nf-κb were detected ...
