NRF2 signalling in cytoprotection and metabolism

British Journal of Pharmacology, EarlyView., 2023
The KEAP1‐NRF2 system plays a central role in cytoprotection in defence mechanisms against oxidative stress. The KEAP1‐NRF2 system has been regarded as a sulfur‐utilizing cytoprotective mechanism, because KEAP1 serves as a biosensor for electrophiles by using its reactive thiols and NRF2 is a transcriptional factor regulating genes involved in sulfur ...

Supersulfide biology and translational medicine for disease control

British Journal of Pharmacology, EarlyView., 2023
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Physiological function and catalytic versatility of bacterial multihaem cytochromescinvolved in nitrogen and sulfur cycling [PDF]

, 2011
Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many

Proteomics of Carbon Fixation Energy Sources in Halothiobacillus neapolitanus [PDF]

, 2019
Through the use of proteomics, it was uncovered that the autotrophic, aerobic purple sulfur bacterium Halothiobacillus neapolitanus displays changes in cellular levels of portions of its carbon dioxide uptake and fixation mechanisms upon switch from ...

Deletion of flavoredoxin gene in Desulfovibrio gigas reveals its participation in thiosulfate reduction [PDF]

, 2005
: The gene encoding Desulfovibrio gigas flavoredoxin was deleted to elucidate its physiological role in the sulfate metabolism. Disruption of flr gene strongly inhibited the reduction of thiosulfate and exhibited a reduced growth in the presence of ...

The chemistry of thiosulfate and vascular calcification [PDF]

Nephrology Dialysis Transplantation, 2011
Thiosulfate has been shown to inhibit vascular calcification in uremic rats and may inhibit calcification in humans with end-stage renal disease but whether this is due to a systemic or local action is unknown. The underlying mechanism is also unclear but complexation of calcium ions has been proposed.In vitro assays were used to determine the effect ...

Electrochemistry and Spectroscopy of Sulfate and Thiosulfate Complexes of Iron Porphyrins [PDF]

, 2002
The electrochemical and spectroscopic properties of the complex formed by the addition of thiosulfate to ferric porphyrins were examined. The NMR spectrum of the thiosulfate–ferric porphyrin complex was consistent with a high-spin ferric complex, while ...

In Situ Formation of a Melt‐Solid Interface Toward Stable Oxygen Reduction in Protonic Ceramic Fuel Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...
