oxymatrine, a potent monosomic alkaloid extracted from chinese herb sophora japonica (sophora flavescens ait.). possesses anti-inflammatory activittyes.  this study was designed to investigate the effects of oxymatrine on nuclear factor–kappa b (nf-κb) and mitogen-activated protein kinase (mapk)-dependent inflammatory responses in lipopolysaccharide (lps)-activated microglia. in this paper, bv2...

signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...

the ds-rna activated protein kinase (pkr) is a serine-threonine kinase with mw of 68 kda. it belongs to a family of kinases that control one of the translational initiation factors, eif2. pkr is produced at high level in response to viral infection. this protein by phosphorylating eif2 inhibits cellular protein synthesis. in this study, the effect of gamma interferon (ifn-γ), an activator, and ...

methods campylobacter jejuni atcc 33291 and seven isolates donated from instituto de biotecnologia were used in this study. the presence of cdt genes in c. jejuni strains was determined by pcr. to evaluate the effect of cdt, hela cells were treated with bacterial lysate, and the damage and morphological changes were analyzed by microscopy, immunofluorescence staining, and flow cytometry. to eva...

Berberis vulgaris L (B. vulgaris) and its main constituent berberine have been used in traditional medicine for a long time. This medicinal plant and berberine have many properties that have attracted the attention of researchers over the time. According to several studies, B. vulgaris and berberine exhibited anti-inflammatory, antioxidant, anticonvulsant, antidepressant, anti-Alzheimer, anti-c...

Considering that MAPK (mitogen- activated protein kinase) signaling pathway has an important role in the progression of inflammatory cytokine secretion in type 2 diabetes mellitus (T2DM), we have recently investigated the reported genetic polymorphism from genome wide association study in MAP3K1 (mitogen-activated protein kinase kinase kinase 1) in diabetes as an important member of MAPK signal...

The aim of the present study was todeterminecharacteristics of Rheb gene and protein in Raini Cashmere goat. Comparative analyses of the nucleotide sequences were performed. Open reading frames (ORFs), theoretical molecular weights of deduced polypeptides, the protein isoelectric point, protein characteristics and three-dimensional structures was predicted using online standard softwares. The f...

MAPK (Mitogen Activated Protein Kinase) is a Ser/Thr kinase, which plays a crucial role in plant growth and development, transferring the extra cellular stimuli into intracellular response etc. Manual identification of these MAPK in the plant genome is tedious and time taking process. There are number of online servers which predict the P-site (phosphorylation site), find the motifs and domain ...
