Regulation of MAP Kinase by the BMP-4/TAK1 Pathway in Xenopus Ectoderm
Bone morphogenetic protein-4 (BMP-4) induces epidermis and represses neural fate in Xenopus ectoderm. Our previous findings implicate p42 Erk MAP kinase (MAPK) in the response to neural induction. We have examined the effects of BMP-4 on MAPK activity in gastrula ectoderm.

Arabidopsis MAP kinase 4 regulates gene expression through transcription factor release in the nucleus [PDF]
Plant and animal perception of microbes through pathogen surveillance proteins leads to MAP kinase signalling and the expression of defence genes. However, little is known about how plant MAP kinases regulate specific gene expression. We report that, in the absence of pathogens, Arabidopsis MAP kinase 4 (MPK4) exists in nuclear complexes with the ...

Efficacy and gastrointestinal tolerability of ML3403, a selective inhibitor of p38 MAP kinase and CBS-3595, a dual inhibitor of p38 MAP kinase and phosphodiesterase 4 in CFA-induced arthritis in rats [PDF]
Mitogen-activated protein kinase (MAPK) p38 inhibitors have entered the clinical phase, although many of them have failed due to high toxicity and lack of efficacy. In the present study we compared the effects of the selective p38 inhibitor ML3403 and the dual p38-PDE4 inhibitor CBS-3595, on inflammatory and nociceptive parameters in a model of ...

MOM-4, a MAP Kinase Kinase Kinase–Related Protein, Activates WRM-1/LIT-1 Kinase to Transduce Anterior/Posterior Polarity Signals in C. elegans [PDF]
In C. elegans, a Wnt/WG-like signaling pathway down-regulates the TCF/LEF-related protein, POP-1, to specify posterior cell fates. Effectors of this signaling pathway include a beta-catenin homolog, WRM-1, and a conserved protein kinase, LIT-1. WRM-1 and LIT-1 form a kinase complex that can directly phosphorylate POP-1, but how signaling activates WRM ...

Integration of a Phosphatase Cascade with the MAP Kinase Pathway provides for a Novel Signal Processing Function [PDF]
We mathematically modeled the receptor-activated MAP kinase signaling by incorporating the regulation through cellular phosphatases. Activation induced the alignment of a phosphatase cascade in parallel with the MAP kinase pathway.

Pseudomonas syringae Effector Protein AvrB Perturbs Arabidopsis Hormone Signaling by Activating MAP Kinase 4 [PDF]
Pathogenic microbes often modulate phytohormone physiology in the host to their advantage. We previously showed that the Pseudomonas syringae effector protein AvrB perturbs hormone signaling, as exemplified by upregulated expression of jasmonic acid response genes, and enhances plant susceptibility.

Cytokine upregulation of proteinase‐activated‐receptors 2 and 4 expression mediated by p38 MAP kinase and inhibitory kappa B kinaseβin human endothelial cells [PDF]
Background and purpose:Up‐regulation of proteinase‐activated receptor‐2 (PAR2) is a factor in a number of disease states and we have therefore examined the signalling pathways involved in the expression of the receptor.Experimental approach:We investigated the effects of tumour necrosis factor‐α (TNF‐α), interleukin‐1β (IL‐1β), trypsin and the PAR2 ...

Dual Specificity Mitogen-activated Protein (MAP) Kinase Phosphatase-4 Plays a Potential Role in Insulin Resistance [PDF]
Insulin is the key hormone that controls glucose homeostasis. Dysregulation of insulin function causes diabetes mellitus. Among the two major forms of diabetes, type 2 diabetes accounts for over 90% of the affected population. The incidence of type 2 diabetes is highly related to obesity.

Incorporating expression data in metabolic modeling: a case study of lactate dehydrogenase [PDF]
Integrating biological information from different sources to understand cellular processes is an important problem in systems biology. We use data from mRNA expression arrays and chemical kinetics to formulate a metabolic model relevant to K562 ...
