P38 MAPK Pharmacological Inhibitor SB203580 Alleviates Total Parenteral Nutrition-Induced Loss of Intestinal Barrier Function but Promotes Hepatocyte Lipoapoptosis [PDF]

Cellular Physiology and Biochemistry, 2017
Background & Aims: Our previous studies have provided evidence that p38 mitogen-activated protein kinase (MAPK) is involved in total parenteral nutrition (TPN)-associated complications, but its exact effects and mechanisms have not been fully ...

Norepinephrine inhibits cell cycle re‐entry of neonatal rat ventricular cardiomyocytes characterized by the absence of de novo nestin expression [PDF]

Physiological Reports
The p38α/β MAPK inhibitor SB203580 in the presence of a phorbol ester (protein kinase C activator) induced cell cycle re‐entry of two subpopulations of neonatal rat ventricular cardiomyocytes (NNVMs) distinguished by the absence or de novo nestin ...

β, β-Dimethylacrylshikonin Triggers Caspase-Mediated Cell Apoptosis via Heme Oxygenase-1 Upregulation and ERK/p38 Activation in Prostate Cancer. [PDF]

J Cell Mol Med
ABSTRACT β, β‐Dimethylacrylshikonin (DMAS), a natural naphthoquinone derivative isolated from the root of a biennial herb belonging to the family Boraginaceae, has been demonstrated to exhibit anti‐cancer and anti‐inflammatory features. Yet, the effects of DMAS on restraining the progression of prostate cancer (PC) remain mostly elusive.

Role of the MAPK pathway in human lung epithelial-like A549 cells apoptosis induced by paraquat [PDF]

Genetics and Molecular Biology, 2020
This study aims to investigate the value of mitogen-activated protein kinases (MAPKs) for paraquat (PQ)-induced apoptosis in human lung epithelial-like A549 cells and the specific mechanism. A549 cell apoptosis were induced by PQ.

Reduced parasite motility and micronemal protein secretion by a p38 MAPK inhibitor leads to a severe impairment of cell invasion by the apicomplexan parasite Eimeria tenella. [PDF]

PLoS ONE, 2015
E. tenella infection is associated with a severe intestinal disease leading to high economic losses in poultry industry. Mitogen activated protein kinases (MAPKs) are implicated in early response to infection and are divided in three pathways: p38 ...

APPLICATION OF INHIBITOR ANALYSIS FOR STUDYING MECHANISMS AND ACTIONS OF POLYMURAMYL, A MURAMYL PEPTIDE-BASED IMMUNE MODULATOR

Медицинская иммунология, 2014
In present study, the following low-MW inhibitors were used to dissect mechanisms of action for two muramyl peptide components of Polymuramyl, an immunomodulatory drug: (1) N-acetyl-D-glucosaminyl-(β1→4)-N-acetyl-D-muramoyl-L-alanyl-D-isoglutaminyl-meso ...

Inhibition of p38 Mitogen-Activated Protein Kinase Impairs Mayaro Virus Replication in Human Dermal Fibroblasts and HeLa Cells

Viruses, 2021
Mayaro virus (MAYV) hijacks the host’s cell machinery to effectively replicate. The mitogen-activated protein kinases (MAPKs) p38, JNK, and ERK1/2 have emerged as crucial cellular factors implicated in different stages of the viral cycle.

Inhibition of p38 MAPK Signaling Regulates the Expression of EAAT2 in the Brains of Epileptic Rats

Frontiers in Neurology, 2018
Seizures induce the release of excitatory amino acids (EAAs) from the intracellular fluid to the extracellular fluid, and the released EAAs primarily comprise glutamic acid (Glu) and asparaginic acid (Asp).

SB203580, a p38MAPK inhibitor, attenuates olfactory dysfunction by inhibiting OSN apoptosis in AR mice (activation and involvement of the p38 mitogen‐activated protein kinase in olfactory sensory neuronal apoptosis of OVA‐induced allergic rhinitis)

Brain and Behavior, 2019
Objective This study aimed to investigate the effect of the p38 mitogen‐activated protein kinase (p38MAPK) signaling pathway on olfactory mucosa function and apoptosis of olfactory sensory neurons (OSNs) in an allergic rhinitis (AR) mouse model.

Upregulation of Chemoresistance by Mg²⁺ Deficiency through Elevation of ATP Binding Cassette Subfamily B Member 1 Expression in Human Lung Adenocarcinoma A549 Cells

Cells, 2021
Several anticancer drugs including cisplatin (CDDP) induce hypomagnesemia. However, it remains fully uncertain whether Mg2+ deficiency affects chemosensitivity of cancer cells.
