Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms

Medicinal Research Reviews, EarlyView.
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...

Mitogen-activated protein kinase pathways

Current Opinion in Cell Biology, 1997
Nearly all cell surface receptors utilize one or more of the mitogen-activated protein kinase cascades in their repertoire of signal transduction mechanisms. Recent advances in the study of such cascades include the cloning of genes encoding novel members of the cascades, further definition of the roles of the cascades in responses to extracellular ...

Mitogen-activated protein kinases

Critical Care Medicine, 2002
The cellular control switches are regulated through an extensive network of interactive intracellular signal transduction pathways, such as the mitogen-activated protein kinase (MAPK) family. The MAPK pathways may play an important role in the inappropriate inflammatory responses that lead to systemic inflammatory response syndrome or multiple organ ...

Mitogen‐activated protein kinases and asthma

Journal of Cellular Physiology, 2004
AbstractMitogen‐activated protein kinases (MAPKs) are evolutionary conserved enzymes which play a key role in signal transduction mediated by cytokines, growth factors, neurotransmitters and various types of environmental stresses. In the airways, these extracellular stimuli elicit complex inflammatory and structural changes leading to the typical ...

Novel mitogen-activated protein kinase kinase inhibitors

Expert Opinion on Investigational Drugs, 2011
the development of new drugs over the last few decades has targeted specific proteins thought to be a key to the disease state. MAPK kinases 1 and 2 (commonly known as MEK1-2) represent such proteins as they lie downstream of important drug targets for oncology, such as EGFR, RAS and RAF.

The mitogen-activated protein kinase activator

Current Opinion in Cell Biology, 1992
The mitogen-activated protein kinase appears to be regulated by another growth factor regulated kinase, the mitogen-activated protein kinase activator. In the past year, much progress has been made in purifying and characterizing the mitogen-activated protein kinase activator, in determining its primary structure, and in identifying another protein ...

Mitogen-activated protein kinases in schizophrenia

Biological Psychiatry, 1999
Mitogen-activated protein kinases (MAPKs) are important mediators of signal transduction from the cell surface to the nucleus and have been implicated in the integration of a variety of physiologic processes in most cells, including neurons. To investigate the possible involvement of MAPKs in schizophrenia, we compared the levels of the MAPK ...

Networking with mitogen-activated protein kinases

Molecular and Cellular Biochemistry, 1993
Mitogen activated protein (MAP) kinases and their target ribosomal protein S6 (RSK) kinases have been recognized as shared components in the intracellular signaling pathways of many diverse cytokines. Recent studies have extended this protein kinase cascade by identifying the major activator of vertebrate MAP kinases as a serine/threonine/tyrosine ...
