Proteoforms in Disease: Biomedical Applications of Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The proteome is a dynamic landscape of proteoforms arising from genetic mutations, alternative splicing, and post‐translational modifications (PTMs), which collectively drive biological function and disease phenotypes. Mass spectrometry (MS)‐based proteomics has emerged as an essential technique for elucidating this molecular complexity ...

Top‐Down CSF Peptidomics Reveals Disease‐Associated Peptide Signatures and Oxidative Modifications in Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder

PROTEOMICS, EarlyView.
ABSTRACT Multiple sclerosis and neuromyelitis optica spectrum disorder (NMOSD) are inflammatory demyelinating diseases of the CNS whose diagnosis is mainly based on clinical evidence, magnetic resonance imaging, and the analysis of cerebrospinal fluid (CSF). Current approaches provide only partial insight into disease‐related biological processes, thus

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Microtubule S-glutathionylation as a potential approach for antimitotic agents

BMC Cancer, 2012
Background Microtubules have been one of the most effective targets for the development of anticancer agents. Cancer cells treated by these agents are characterized by cell arrest at G2/M phase.

S‑glutathionylation of MaWRKY44 orchestrates a MaZFP139‐MaWRKY44‐MaGSTU07 cascade to enhance banana cold tolerance

Journal of Integrative Plant Biology, EarlyView.
In banana, at low temperatures (7°C), the transcription factor MaZFP139 activates MaWRKY44 expression. MaWRKY44 binds to the W‐box sites in the promoter of the glutathione S‐transferase gene MaGSTU07 to enhance reactive oxygen species scavenging. S‐glutathionylation protects MaWRKY44 from oxidation‐induced degradation, reinforcing antioxidant defenses ...

Early oxidation‐related changes in aqueous humor following eye exposure to ultraviolet‐A radiation

Photochemistry and Photobiology, EarlyView.
UVA exposure induces early oxidative alterations in the aqueous humor, disrupting its antioxidant balance. Levels of ascorbic acid, reduced glutathione (GSH), and the GSH/GSSG ratio decrease, while oxidized glutathione (GSSG), S‐glutathionylated proteins (PSSG), and malondialdehyde (MDA), a lipid peroxidation by‐product, increase.

Glutathione S-transferase pi modulates NF-κB activation and pro-inflammatory responses in lung epithelial cells

Redox Biology, 2016
Nuclear Factor kappa B (NF-κB) is a transcription factor family critical in the activation of pro- inflammatory responses. The NF-κB pathway is regulated by oxidant-induced post-translational modifications. Protein S-glutathionylation, or the conjugation

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
