Inhibition of Mitogen-Activated Protein Kinase Erk1/2 Promotes Protein Degradation of ATP Binding Cassette Transporters A1 and G1 in CHO and in HuH7 cells. [PDF]

, 2013
Signal transduction modulates expression and activity of cholesterol transporters. We recently demonstrated that the Ras/mitogen-activated protein kinase (MAPK) signaling cascade regulates protein stability of Scavenger Receptor BI (SR-BI) through ...

Endothelin-1 Induces Contraction via a Syk-Mediated p38 Mitogen-Activated Protein Kinase Pathway in Rat Aortic Smooth Muscle

Journal of Pharmacological Sciences, 2007
Although spleen tyrosine kinase (Syk) has crucial roles in various cells, its function on vascular smooth muscle contraction has not been determined. In the present study, we performed experiments to determine if Syk contributes to the endothelin-1 (ET-1)

Structural Mechanism for the Specific Assembly and Activation of the Extracellular Signal Regulated Kinase 5 (ERK5) Module [PDF]

, 2013
Mitogen-activated protein kinase (MAPK) activation depends on a linear binding motif found in all MAPK kinases (MKK). In addition, the PB1 (Phox and Bem1) domain of MKK5 is required for extracellular signal regulated kinase 5 (ERK5) activation.

Nitric Oxide/cGMP Signaling Pathway Protects RAW264 Cells Against Nitric Oxide-Induced Apoptosis by Inhibiting the Activation of p38 Mitogen-Activated Protein Kinase

Journal of Pharmacological Sciences, 2006
.: Nitric oxide (NO) induces apoptosis in various cells lines, while activation of the NO/cGMP signaling pathway prevents apoptosis induced by diverse stimuli, including NO.

Targeting of p38 Mitogen-Activated Protein Kinases to MEF2 Transcription Factors [PDF]

Molecular and Cellular Biology, 1999
Mitogen-activated protein (MAP) kinase-mediated signalling to the nucleus is an important event in the conversion of extracellular signals into a cellular response. However, the existence of multiple MAP kinases which phosphorylate similar phosphoacceptor motifs poses a problem in maintaining substrate specificity and hence the correct biological ...

Interacting protein kinases involved in the regulation of flagellar length [PDF]

, 2006
A striking difference of the life stages of the protozoan parasite Leishmania is a long flagellum in the insect stage promastigotes and a rudimentary organelle in the mammalian amastigotes.

p38 regulates the tumor suppressor PDCD4 via the TSC-mTORC1 pathway

Cell Stress, 2021
Programmed cell death protein 4 (PDCD4) exerts critical functions as tumor suppressor and in immune cells to regulate inflammatory pro-cesses. The phosphoinositide 3-kinase (PI3K) promotes degradation of PDCD4 via mammalian target of rapamycin complex 1 (

The structure of mitogen-activated protein kinase p38 at 2.1-Å resolution [PDF]

Proceedings of the National Academy of Sciences, 1997
The structure of mitogen-activated protein (MAP) kinase p38 has been solved at 2.1-Å to an R factor of 21.0%, making p38 the second low activity MAP kinase solved to date. Although p38 is topologically similar to the MAP kinase ERK2, the phosphorylation Lip (a regulatory loop near the active ...

Evaluation of 2-(4-Chlorophenyl)-4-(4-fluorophenyl)-5-pyridin-4-yl-1,2-dihydropyrazol-3-one as a p38 MAPK inhibitor in MCF-7 and MDA-MB-231 breast cancer cell lines

Al-Mustansiriyah Journal of Pharmaceutical Sciences
Breast cancer is a diverse disease with high mortality rates, often due to metastasis. Breast cancer subtypes vary by the expression of progesterone receptor, human epidermal growth factor receptor 2, and estrogen receptor.
