Divergent behavior of hydrogen sulfide pools and of the sulfur metabolite lanthionine, a novel uremic toxin, in dialysis patients. [PDF]

, 2016
Dialysis patients display a high cardiovascular mortality, the causes of which are still not completely explained, but are related to uremic toxicity.

Proteomic Analysis Infers Optimized ATP‐Production in Guard Cell Mitochondria

Physiologia Plantarum, Volume 177, Issue 5, September/October 2025.
ABSTRACT Guard cells are highly specialised leaf cells which regulate leaf transpiration and carbon fixation. As such, they are instrumental in balancing water use efficiency and photosynthetic activity. This unique function of guard cells requires them to quickly accumulate solutes for ATP‐dependent stomatal opening, but how this affects mitochondrial

Dimethyl Sulfoxide (DMSO) as a Potential Source of Interference in Research Related to Sulfur Metabolism—A Preliminary Study

Antioxidants
Dimethyl sulfoxide (DMSO), an organosulfur compound, is widely used as the gold standard solvent in biological research. It is used in cell culture experiments and as a component of formulations in in vivo studies.

Evidence of endogenously produced hydrogen sulfide (H2S) and persulfidation in male reproduction

Scientific Reports, 2022
Persulfidation contributes to a group of redox post-translational modifications (PTMs), which arise exclusively on the sulfhydryl group of cysteine as a result of hydrogen sulfide (H2S) action.

Hydrogen Sulfide Protects Erectile Function Through Stimulation of Antioxidant Defense in the Corpus Cavernosum: Insights From SG1002 Administration and Cystathionine γ‐Lyase Knockout

The FASEB Journal, Volume 39, Issue 15, 15 August 2025.
Chronic consumption of a western diet suppressed corpus cavernosum cystathionine γ‐lyase (CSE) protein content and H2S production and was associated with elevated penile reactive oxygen species (ROS) levels and impaired erectile function. CSE knockout mice demonstrate impaired erectile function, elevated penile ROS levels, and suppressed corpus ...

Production of hydrogen sulfide from D-cysteine and its therapeutic potential

Frontiers in Endocrinology, 2013
Accumulating evidence shows that H2S has physiological functions in various tissues and organs. It includes regulation of neuronal activity, vascular tension, a release of insulin, and protection of the heart, kidney and brain from ischemic insult. H2S

3‐Mercaptopyruvate sulfurtransferase supports endothelial cell angiogenesis and bioenergetics [PDF]

British Journal of Pharmacology, 2019
Background and PurposeDuring angiogenesis, quiescent endothelial cells (ECs) are activated by various stimuli to form new blood vessels from pre‐existing ones in physiological and pathological conditions. Many research groups have shown that hydrogen sulfide (H2S), the newest member of the gasotransmitter family, acts as a proangiogenic factor. To date,

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]

, 2018
Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...

Catalytic Site Cysteines of Thiol Enzyme: Sulfurtransferases [PDF]

Journal of Amino Acids, 2011
Thiol enzymes have single- or double-catalytic site cysteine residues and are redox active. Oxidoreductases and isomerases contain double-catalytic site cysteine residues, which are oxidized to a disulfide via a sulfenyl intermediate and reduced to a thiol or a thiolate. The redox changes of these enzymes are involved in their catalytic processes.

Development and Application of a 1,8‐Naphthalimide‐Based Fluorescent Probe for Sensitive Detection of Hydrogen Sulfide in Human Blood Serum

Luminescence, Volume 40, Issue 8, August 2025.
The target 1,8‐napthalimide‐based fluorescent probe was prepared and successfully applied for H2S detection in human blood serum whereby the concentration of H2S in human blood serum was found to be 16.2 μmol L−1. The accuracy of the developed method was confirmed by the standard addition method and UV‐Vis spectrophotometry method using methylene blue.
