Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Antioxidant Supplementation in the Treatment of Aging-Associated Diseases [PDF]

, 2016
Oxidative stress is generally considered as the consequence of an imbalance between pro- and antioxidants species, which often results into indiscriminate and global damage at the organismal level.

Coenzyme A mitigates cystine‐deprivation‐induced ferroptosis by suppressing the iron‐starvation response

The FEBS Journal, EarlyView.
Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

Electrodes modified with lipid membranes to study quinone oxidoreductases

, 2009
Quinone oxidoreductases are a class of membrane enzymes that catalyse the oxidation or reduction of membrane-bound quinols/quinones. The conversion of quinone/quinol by these enzymes is difficult to study because of the hydrophobic nature of the enzymes ...

Cytochrome c: Surfing Off of the Mitochondrial Membrane on the Tops of Complexes III and IV [PDF]

, 2019
The proper arrangement of protein components within the respiratory electron transport chain is nowadays a matter of intense debate, since altering it leads to cell aging and other related pathologies.

Omental adipocyte hypertrophy relates to coenzyme Q10 redox state and lipid peroxidation in obese women

Journal of Lipid Research, 2015
Occurrence of oxidative stress in white adipose tissues contributes to its dysfunction and the development of obesity-related metabolic complications. Coenzyme Q10 (CoQ10) is the single lipophilic antioxidant synthesized in humans and is essential for ...

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

The FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

Amino acid sequence and distribution of mRNA encoding a major skeletal muscle laminin binding protein: an extracellular matrix-associated protein with an unusual COOH-terminal polyaspartate domain. [PDF]

, 1988
Two cDNAs encoding an abundant chicken muscle extracellular matrix (ECM)-associated laminin-binding protein (LBP) have been isolated and sequenced. The predicted primary amino acid sequence includes a probable signal peptide and a site for N-linked ...

The GmGT‐2F, a trihelix transcription factor, regulates seed oil content by directly activating GmAGAL transcription in soybean

Journal of Integrative Plant Biology, EarlyView.
In soybean, the trihelix transcription factor GmGT‐2F positively regulates the expression of the α‐galactosidase gene GmAGAL, thereby modulating seed oil content. The cyclophilin GmCYP2 interacts with GmGT‐2F and suppresses GmAGAL activation. Haplotype diversity analysis of GmGT‐2F, GmCYP2, and GmAGAL identified favorable haplotype combinations ...

Mitochondrial alterations as potential early events in neuromuscular junction remodelling with muscle disuse

Experimental Physiology, EarlyView.
Abstract Physical inactivity impairs neuromuscular health, promoting skeletal muscle atrophy, mitochondrial changes, and neuromuscular junction (NMJ) instability. However, the interplay between mitochondria and NMJ alterations in the context of muscle disuse remains underexplored.
