Activation of the Sap-1a Transcription Factor by the c-Jun N-terminal Kinase (JNK) Mitogen-activated Protein Kinase [PDF]
Ternary complex factors (TCFs) bind to the serum response element in the c-fos promoter and mediate its activation by many extracellular stimuli. Some of these stimuli activate the ERK subclass of mitogen-activated protein kinases (MAPKs) that target the TCF Sap-1a.

Vomitoxin-Induced Cyclooxygenase-2 Gene Expression in Macrophages Mediated by Activation of ERK and p38 but Not JNK Mitogen-Activated Protein Kinases [PDF]
Vomitoxin (VT) and other trichothecene mycotoxins mediate a broad range of immunotoxic effects via the induction of inflammation-associated genes in leukocytes. The purpose of this study was to test the hypothesis that VT induces cyclooxygenase-2 (COX-2)

Activation of G1 Progression, JNK Mitogen-activated Protein Kinase, and Actin Filament Assembly by the Exchange Factor FGD1 [PDF]
Cdc42 has been shown to control bifurcating pathways leading to filopodia formation/G1 cell cycle progression and to JNK mitogen-activated protein kinase activation. To dissect these pathways further, the cellular effects induced by a Cdc42 guanine nucleotide exchange factor, FGD1, have been examined.

Scaffold Role of a Mitogen-activated Protein Kinase Phosphatase, SKRP1, for the JNK Signaling Pathway [PDF]
Stress-activated protein kinase (SAPK) pathway-regulating phosphatase 1 (SKRP1) has been identified as a member of the mitogen-activated protein kinase (MAPK) phosphatase (MKP) family that interacts physically with the MAPK kinase (MAPKK) MKK7, a c-Jun N-terminal kinase (JNK) activator, and inactivates the MAPK JNK pathway.

Activation of JNK, p38 and ERK mitogen-activated protein kinases by chromium(VI) is mediated through oxidative stress but does not affect cytotoxicity [PDF]
In this study we have explored the involvement of oxidative stress in Cr(VI)-induced JNK, p38 and ERK signaling pathways and their effects on Cr(VI) cytotoxicity in human non-small cell lung carcinoma CL3 cells.

Drosophila heat shock response requires the JNK pathway and phosphorylation of mixed lineage kinase at a conserved serine-proline motif. [PDF]
Defining context specific requirements for proteins and pathways is a major challenge in the study of signal transduction. For example, the stress-activated protein kinase (SAPK) pathways are comprised of families of closely related transducers that are ...

Ultraviolet Light-induced Stimulation of the JNK Mitogen-activated Protein Kinase in the Absence of Src Family Tyrosine Kinase Activation [PDF]
In T cells, the JNK mitogen-activated protein kinase is activated by simultaneous stimulation of the T-cell receptor and CD28 or by a number of stress stimuli including ultraviolet light, hydrogen peroxide, and anisomycin. Lck, a Src family kinase, is essential for T-cell receptor-mediated activation of JNK.

Activation of the cellular mitogen-activated protein kinase pathways ERK, P38 and JNK duringToxoplasma gondiiinvasion [PDF]
Host cell invasion is essential for the pathogenicity of the obligate intracellular protozoan parasite Toxoplasma gondii. In the present study, we evaluated the ability of T. gondii tachyzoites to trigger phosphorylation of the different mitogen-activated protein kinases (MAPK) in human monocytic cells THP1.

JNK and p38 Mitogen-Activated Protein Kinase Pathways Contribute to Porcine Circovirus Type 2 Infection [PDF]
ABSTRACTInfection with a wide variety of viruses often perturbs host cell signaling pathways including the Jun NH2-terminal kinase/stress-activated kinase (JNK/SAPK) and the p38 mitogen-activated protein kinase (p38/MAPK), which are important components of cellular signal transduction pathways.

The mitogen-activated protein kinome from Anopheles gambiae: identification, phylogeny and functional characterization of the ERK, JNK and p38 MAP kinases [PDF]
Abstract Background Anopheles gambiae is the primary mosquito vector of human malaria parasites in sub-Saharan Africa. To date, three innate immune signaling pathways, including the nuclear factor (NF)-kappaB-dependent Toll and immune deficient (IMD) pathways and the Janus kinase/signal transducers and ...
