An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Enhanced thermo-oxidative stability of polydicyclopentadiene containing covalently bound nitroxide groups [PDF]

open access: yes, 2022
International audienceThe antioxidant 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) group was covalently introduced into polydicyclopentadiene (PDCPD) through ring-opening metathesis polymerization (ROMP) copolymerization of dicyclopentadiene (DCPD) with ...

The role of endogenous hydratable phospholipids in enhancing the oxidative stability of tiger nut (Cyperus esculentus L.) oil

open access: yesFood Chemistry: X
Tiger nut oil (TNO) is a promising oil due to its excellent oxidative stability. The simulated system was developed using stripped tiger nut oil (STNO) and hydratable phospholipids (HP) extracted from TNO to study HP's antioxidant role.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Influence of oxidative stress, diaphragm fatigue and inspiratory muscle training on the plasma cytokine response to maximum sustainable voluntary ventilation

open access: yes, 2014
The influence of oxidative stress, diaphragm fatigue and inspiratory muscle training (IMT) on the cytokine response to maximum sustainable voluntary ventilation (MSVV) is unknown.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

oxidative stability of seafood

open access: yes, 2023
Seafood is one of the most nutritious food sources, the quality-nutritional properties, odor, taste, texture, and color of seafood are of utmost importance which need to be prevented or control from oxidation. Differences in the endogenous pools of lipids and pro-and antioxidants, including their direct contact with each other and atmosphere, explain ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
