Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Crystal structure of a photosynthetic LH1-RC in complex with its electron donor HiPIP

Nature Communications, 2021
The high potential iron-sulfur (HiPIP) proteins are direct electron donors to the light-harvesting-reaction center complexes (LH1-RC) in photosynthetic β- and γ-Proteobacteria.

Functional studies on oligotropha carboxidovorans molybdenum–copper CO dehydrogenase produced in escherichia coli [PDF]

, 2018
The Mo/Cu-dependent CO dehydrogenase (CODH) from Oligotropha carboxidovorans is an enzyme that is able to catalyze both the oxidation of CO to CO2 and the oxidation of H2 to protons and electrons. Despite the close to atomic resolution structure (1.1 Å),

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

The ins and outs of metal homeostasis by the root nodule actinobacterium Frankia [PDF]

, 2014
Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Identification of YdhV as the first molybdoenzyme binding a Bis-Mo-MPT cofactor in escherichia coli [PDF]

, 2019
The oxidoreductase YdhV in Escherichia coli has been predicted to belong to the family of molybdenum/tungsten cofactor (Moco/Wco)-containing enzymes. In this study, we characterized the YdhV protein in detail, which shares amino acid sequence homology ...

Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

Advanced Functional Materials, EarlyView.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.
