Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Ageing alters cysteine oxidation‐regulated redox signalling in skeletal muscle: Integrative omics and AI‐based structural predictions

Experimental Physiology, EarlyView.
Abstract Ageing is associated with loss of skeletal muscle mass and strength (sarcopenia) and disrupted redox homeostasis. Redox signalling is essential for muscle adaptation, yet the mechanisms by which ageing disrupts cysteine‐based regulation are poorly defined. The drivers of site‐specific reactivity and signalling specificity in aged muscle remain

Suppression of Spry1 reduces HIF1α-dependent glycolysis and impairs angiogenesis in BRAF-mutant cutaneous melanoma

Journal of Experimental & Clinical Cancer Research
Background About 50% of cutaneous melanoma (CM) harbors the activating BRAFV600 mutation which exerts most of the oncogenic effects through the MAPK signaling pathway.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

Extracellular production of reactive oxygen species in response to abiotic stress in seeds [PDF]

, 2009
Reactive oxygen species (ROS), such as superoxide (O2 •‾), hydrogen peroxide (H2O2), singlet oxygen (1O2) and the hydroxyl radical (•OH) can damage essential biomolecules including nucleic acids, proteins and lipids, causing damage to various ...

Engineering Mosaic T7 Bacteriophages for Dual Peptide Display to Enable Cellular Targeting and Ligand‐Directed Protein Capture

Biotechnology Journal, Volume 21, Issue 11, November 2026.
Graphical Abstract and Lay Summary A mosaic T7 phage platform enables simultaneous display of two independent peptides on the same phage particle. The modular design integrates receptor targeting, protein capture, and tissue‐directed in vivo phage display, establishing a versatile methodology for multifunctional phage engineering, receptor ...

Sphingosine‐1‐Phosphate Attenuates LPS‐Induced Inflammatory Cardiac Injury in Association With RASGRP1–S100A9–NLRP3 Signaling

Drug Development Research, Volume 87, Issue 7, November 2026.
ABSTRACT Lipopolysaccharide (LPS) induces endotoxemia‐associated inflammatory cardiac injury rather than classical viral or autoimmune myocarditis. Sphingosine‐1‐phosphate (S1P) regulates cardiovascular and immune responses, predominantly through S1P receptors, but whether it also modulates macrophage‐associated inflammatory signaling during LPS ...

The Protein Interactome of Streptococcus pneumoniae and Bacterial Meta-interactomes Improve Function Predictions

, 2017
Identification of protein interactions in bacterial species can help define the individual roles that proteins play in cellular pathways and pathogenesis. Very few protein interactions have been identified for the important human pathogen
