Selenoproteins Protect Against Avian Liver Necrosis by Metabolizing Peroxides and Regulating Receptor Interacting Serine Threonine Kinase 1/Receptor Interacting Serine Threonine Kinase 3/Mixed Lineage Kinase Domain-Like and Mitogen-Activated Protein Kinase Signaling

open access: yesFrontiers in Physiology, 2021
Liver necroptosis of chicks is induced by selenium (Se)/vitamin E (VE) deficiencies and may be associated with oxidative cell damage. To reveal the underlying mechanisms of liver necrosis, a pool of the corn–soy basal diet (10 μg Se/kg; no VE added), a ...

Dynamic activation and regulation of the mitogen-activated protein kinase p38 [PDF]

open access: yesProceedings of the National Academy of Sciences, 2018
Significance The physical basis for the regulation of protein MAP kinases is key to understanding their role in cellular signaling in human biology and disease. However, the biochemical events that lead to MAPK activation are not well understood. Here, using biomolecular NMR dynamics measurements, we show that kinase activation is not

p38 Mitogen-Activated Protein Kinase and Hematologic Malignancies

open access: yesArchives of Pathology & Laboratory Medicine, 2009
Abstract Context. —p38 mitogen-activated protein kinase (MAPK) signaling has been implicated in responses ranging from apoptosis to cell cycle, induction of expression of cytokine genes, and differentiation. This plethora of activators conveys the complexity of the p38 pathway.

Capsaicin Acts Through Reducing P38 MAPK-Dependent Thymidylate Synthase Expression to Enhance 5-Fluorouracil-Induced Cytotoxicity in Human Lung Cancer Cells

open access: yesNatural Product Communications, 2021
Capsaicin, an ingredient of green and red bell peppers, shows anticancer activity in several malignant cell lines. Thymidylate synthase (TS) is a well-validated anticancer drug target in non-small cell lung cancer (NSCLC) cells.

Endothelin Type B Receptor–Induced Sustained Ca2+ Influx Involves Gq/11/Phospholipase C–Independent, p38 Mitogen-Activated Protein Kinase–Dependent Activation of Na+/H+ Exchanger

open access: yesJournal of Pharmacological Sciences, 2010
The mechanism for sustained Ca2+ influx activated by G protein–coupled receptors was examined. In Chinese hamster ovary cells expressing recombinant human endothelin type B receptor (ETBR) and endogenous P2Y receptor (P2Y-R), endothelin-1 elicited a ...

p38 Mitogen-Activated Protein Kinases on the Body Surface – A Function for p38δ [PDF]

open access: yesJournal of Investigative Dermatology, 2003
The p38 family of mitogen-activated protein kinases includes p38 alpha (SAPK2a, CSBP), p38 beta (SAPK2b), p38 delta (SAPK4), and p38 gamma (SAPK3/ERK6). p38 alpha and p38 beta are widely expressed p38 isoforms that are involved in regulation of cell proliferation, differentiation, development, and response to stress.

Total ginsenosides suppress monocrotaline-induced pulmonary hypertension in rats: involvement of nitric oxide and mitogen-activated protein kinase pathways

open access: yesJournal of Ginseng Research, 2016
Background: Ginsenosides have been shown to exert beneficial pharmacological effects on the central nervous, cardiovascular, and endocrine systems. We sought to determine whether total ginsenosides (TG) inhibit monocrotaline (MCT)-induced pulmonary ...

Role of p38 Mitogen-Activated Protein Kinases in Preconditioning [PDF]

open access: yesCirculation Research, 2000
Preconditioning, the phenomenon whereby brief episodes of ischemia or pharmacological agents protect the myocardium against subsequent ischemic injury, consists of an early and a late phase.1 The early phase develops immediately and disappears within 1 to 2 hours of ischemic preconditioning stimulus, whereas the late phase, also known as the “second ...

Activation of the cellular mitogen-activated protein kinase pathways ERK, P38 and JNK during Toxoplasma gondii invasion

open access: yesParasite, 2003
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.
