Involvement of the mitogen-activated protein (MAP) kinase signalling pathway in host cell invasion by Toxoplasma gondii

Parasite, 2000
Little is known about signalling in Toxoplasma gondii, but it is likely that protein kinases might play a key role in the parasite proliferation, differentiation and probably invasion.

Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

Advanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

siRNA Delivery via Cross‐Linked Gelatin Microparticles Enables Targeted Modulation of Osteogenic‐Vascular Cross‐Talk: An Advanced Human 3D in Vitro Test System for Therapeutic siRNA

Advanced Healthcare Materials, EarlyView.
Osteogenic‐angiogenic cross‐talk is a vital prerequisite for vascularized bone regeneration. In this study, we investigated the effects of siRNA‐mediated silencing of two inhibitory proteins, Chordin and WWP‐1, via CaP‐NP‐loaded gelatin microparticles in osteogenically differentiated microtissues.

Mitogen-activated protein kinases in normal and (pre)neoplastic ovarian surface epithelium

Reproductive Biology and Endocrinology, 2003
Mitogen-activated protein kinases (MAPKs) are a group of serine/threonine kinases which are activated in response to a diverse array of extracellular stimuli and mediate signal transduction from the cell surface to the nucleus.

Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

Advanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

Big Mitogen-Activated Protein Kinase 1 Protects Cultured Rat Aortic Smooth Muscle Cells From Oxidative Damage

Journal of Pharmacological Sciences, 2011
.: Oxidative stress is considered a major mediator of arteriosclerosis. In vascular smooth muscle cells, oxidative stress–induced cell death (including apoptosis) is probably related to arterial calcification in arteriosclerosis.

Characterization of the Structure and Function of the Fourth Member of p38 Group Mitogen-activated Protein Kinases, p38δ*

Journal of Biological Chemistry, 1997
We have cloned and characterized a new member of the p38 group of mitogen-activated protein kinases here termed p38δ. Sequence comparisons revealed that p38δ is approximately 60% identical to the other three p38 isoforms but only 40–45% to the other ...

A Patient‐Derived Organoid Biobank of Adamantinomatous Craniopharyngioma as a Platform for Drug Discovery

Advanced Science, EarlyView.
This study successfully establishes adamantinomatous craniopharyngioma (ACP) patient‐derived organoids (PDOs) that preserve the histopathological and genetic features of the original tumors. Through drug sensitivity assays and subsequent mechanistic analyses, the study demonstrates that Ceritinib exerts its inhibitory effects on ACP PDO growth by ...

Stress and Vascular Responses: Mitogen-Activated Protein Kinases and Activator Protein-1 as Promising Therapeutic Targets of Vascular Remodeling

Journal of Pharmacological Sciences, 2003
Mitogen-activated protein kinases (MAP kinases), including extracellular signal-regulated kinase (ERK), c-Jun NH2-terminal kinase (JNK), and p38, play a central role in cellular responses by various stress stimuli such as cell proliferation, apoptosis ...

Neddylation Targets and Stabilizes NLRP3 to Augment Inflammasome‐Mediated Colitis and Mood Disorder

Advanced Science, EarlyView.
NLRP3 inflammasome contributes to colitis and mood disorder. This study demonstrates that neddylation targets NLRP3 at K287, which hinders its interaction with K48‐linked ubiquitination E3 Trim31 and thereby stabilizes it. Neddylation blockade in myeloid cells and microglia mitigates DSS‐induced colitis and psychological stress‐induced anxiety‐like ...
