Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Efficiency of Mammalian Selenocysteine Incorporation [PDF]

Journal of Biological Chemistry, 2004
Five components have thus far been identified that are necessary for the incorporation of selenocysteine (Sec) into approximately 25 mammalian proteins. Two of these are cis sequences, a SECIS element in the 3'-untranslated region and a Sec codon (UGA) in the coding region.

Folding of peptides and proteins: role of disulfide bonds, recent developments

Biomolecular Concepts, 2013
Disulfide-containing proteins are ideal models for studies of protein folding as the folding intermediates can be observed, trapped, and separated by HPLC during the folding reaction.

Unraveling the Physicochemical Landscape of Organoselenium Compounds in Nanocarrier Systems

The Chemical Record, EarlyView.
Main nanocarriers employed to enhance the bioavailability and transport of organoselenium compounds. The image illustrates the key interaction forces that stabilize these organoselenium species in solution, enabling their application in drug delivery systems, catalysis, photoelectronic devices, and sensing technologies. In recent years, publications on

Dietary interventions in acute kidney injury: From molecular mechanism to clinical trials

Experimental Physiology, EarlyView.
Abstract Ageing impairs renal resilience with an elevated risk of frequent and harmful acute kidney injury (AKI) that causes substantial morbidity and mortality among hospitalized patients. Since different damaging stimuli at the molecular, cellular and functional level contribute to this loss in kidney function, AKI's pathophysiology is heterogeneous ...

Bioinformatic analysis of glutathione peroxidase family from theobroma cacao and gene expression during Moniliophthora perniciosa infection.[Poster-B185] [PDF]

, 2018
Glutathione peroxidases (GPXs) are enzymes which are part of the antioxidant system of the cell. Mammalian GPXs are known as selenoproteins because containing the selenocysteine (Sec) amino acid. In plants, these proteins are less known.

LRP8‐mediated selenocysteine uptake is a targetable vulnerability in MYCN‐amplified neuroblastoma

EMBO Molecular Medicine, 2023
Ferroptosis has emerged as an attractive strategy in cancer therapy. Understanding the operational networks regulating ferroptosis may unravel vulnerabilities that could be harnessed for therapeutic benefit. Using CRISPR‐activation screens in ferroptosis

Molecular Probes for Tracking Reactive Oxygen Species at the Organelle Interface

Analysis &Sensing, Volume 6, Issue 3, May 2026.
This perspective charts the frontier of visualizing compartmentalized redox signaling across mitochondria, the ER, lysosomes, and the underexplored peroxisome. It discusses evolving molecular probe designs, the integration of multiplexed imaging, and the specific engineering challenges for tracking ROS at organelle interfaces.
