The c-Jun N-terminal protein kinase family of mitogen-activated protein kinases (JNK MAPKs).

The International Journal of Biochemistry & Cell Biology, 2001
The c-Jun N-terminal protein kinase mitogen-activated protein kinases (JNK MAPKs) are an evolutionarily-conserved family of serine/threonine protein kinases. First identified in 1990 when intraperitoneal injection of the protein synthesis inhibitor cycloheximide activated a 54 kDa protein kinase, the JNK MAPKs have now taken on a prominent role in ...

Structure and Expression of Carp Mitogen--Activated Protein Kinases Homologous to Mammalian JNK/SAPK

Journal of Biochemistry, 1997
Two distinct stress-activated protein kinase (JNKa and b) cDNAs were isolated from a carp ovary cDNA library. These cDNAs contained a full-length open reading frame encoding 427 amino acid residues with a predicted mass of 48.6 kDa. The deduced amino acid sequences of JNKa and b were 95.8% identical, with 18 residues replaced, and showed a high degree ...

Analyzing JNK and p38 mitogen-activated protein kinase activity

2001
Publisher Summary The JNK and p38 mitogen-activated protein (MAP) kinase groups are important for many physiological processes including cell growth, oncogenic transformation, cell differentiation, apoptosis, and the immune response. To understand the role of JNK and p38 MAP kinases in the cell, several protocols for measuring their activation state ...

JNK and ERK mitogen-activated protein kinases mediate THDA-induced apoptosis in K562 cells

Cell Biology and Toxicology, 2007
2-(6-(2-thieanisyl)-3(Z)-hexen-1, 5-diynyl) aniline (THDA), an enediyne compound, was identified in our laboratory as a novel antineoplastic agent against human leukemia K562 cells. THDA-induced apoptosis was associated with the upregulation of Bax, downregulation of X-linked inhibitor of apoptosis (XIAP), as well as the activation of caspase-3 and ...

Cry1Ac toxin induces macrophage activation via ERK1/2, JNK and p38 mitogen-activated protein kinases

The International Journal of Biochemistry & Cell Biology, 2016
The Cry1Ac toxin from Bacillus thuringiensis is used commercially as a bio-insecticide and is expressed in transgenic plants that are used for human and animal consumption. Although it was originally considered innocuous for mammals, the Cry1Ac toxin is not inert and has the ability to induce mucosal and systemic immunogenicity.

Phospho-specific mitogen-activated protein kinase antibodies for ERK, JNK, and p38 activation

2001
Publisher Summary The phosphorylation of cellular proteins or enzymes may result in alteration of their conformation and/or their enzyme activity. This is best illustrated by a group of enzymes collectively known as mitogen-activated protein (MAP) kinases, whose dual phosphorylation by upstream protein kinases results in their activation.

Repeated fasting stress causes activation of mitogen-activated protein kinases (ERK/JNK) in rat liver

Hepatology, 2002
Mitogen-activated protein kinases (MAPK)-signaling pathways play key roles in cytoplasmic-nuclear signal transmission in response to various extracellular stimuli. In this study, we investigated the effect of repeated fasting stress on activation of the 3 members of the MAPK family, the extracellular signal-regulated kinase ...

Targeting the MKK7–JNK (Mitogen-Activated Protein Kinase Kinase 7–c-Jun N-Terminal Kinase) Pathway with Covalent Inhibitors

Journal of Medicinal Chemistry, 2019
The protein kinase MKK7 is linked to neuronal development and the onset of cancer. The field, however, lacks high-quality functional probes that would allow for the dissection of its detailed functions. Against this background, we describe an effective covalent inhibitor of MKK7 based on the pyrazolopyrimidine scaffold.

Palmitic acid promotes endothelial progenitor cells apoptosis via p38 and JNK mitogen-activated protein kinase pathways

Atherosclerosis, 2010
Recent studies have demonstrated that palmitic acid (PA) could regulate endothelial progenitor cells (EPCs) function (migration, proliferation, survival and angiogenesis) via various signal pathways, but the effect of PA on EPCs apoptosis and associated mechanisms are still elusive.The human EPCs were obtained by Ficoll density gradient centrifugation ...

Quercetin attenuates cardiomyocyte apoptosis via inhibition of JNK and p38 mitogen-activated protein kinase signaling pathways

Gene, 2016
Quercetin (Que), a plant-derived flavonoid, possesses various biological functions. Moreover, Que exerts multiple beneficial actions in treatment of cardiovascular diseases and there are an inverse association between Que intakes and occurrence and development of various cardiovascular diseases. Some researchers have inferred that the mechanisms of Que
