Supersulfide biology and translational medicine for disease control

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 1, Page 115-130, January 2026.
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

Mercaptopyruvate acts as endogenous vasodilator independently of 3-mercaptopyruvate sulfurtransferase activity

open access: yesNitric Oxide, 2018
Hydrogen sulfide (H2S) is produced by the action of cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) or 3-mercaptopyruvate sulfurtransferase (3-MST). 3-MST converts 3-mercaptopyruvate (MPT) to H2S and pyruvate. H2S is recognized as an endogenous gaseous mediator with multiple regulatory roles in mammalian cells and organisms.

Synthesis of Sulfides and Persulfides Is Not Impeded by Disruption of Three Canonical Enzymes in Sulfur Metabolism

open access: yesAntioxidants, 2023
Reactive sulfur species, or persulfides and polysulfides, such as cysteine hydropersulfide and glutathione persulfide, are endogenously produced in abundance in both prokaryotes and eukaryotes, including mammals.

A critical role for cystathionine-β-synthase in hydrogen sulfide-mediated hypoxic relaxation of the coronary artery [PDF]

open access: yes, 2017
Hypoxia-induced coronary artery vasodilatation protects the heart by increasing blood flow under ischemic conditions, however its mechanism is not fully elucidated.

The Concise Guide to PHARMACOLOGY 2025/26: Enzymes

open access: yesBritish Journal of Pharmacology, Volume 182, Issue S1, Page S307-S403, December 2025.
The Concise Guide to Pharmacology 2025/26 marks the seventh edition in this series of biennial publications in the British Journal of Pharmacology. Presented in landscape format, the guide provides a comparative overview of the pharmacology of drug target families. The concise nature of the Concise Guide refers to the style of presentation, being clear,

Dietary methionine depletion and hydrogen sulfide‐producing genes in perivascular adipose tissue of male Wistar rats

open access: yesPhysiological Reports, Volume 13, Issue 24, December 2025.
Abstract Perivascular adipose tissue (PVAT) regulates vascular tone, and high‐fat diets reportedly lead to the loss of its anti‐contractile properties. Methionine restriction recapitulates many caloric restriction metabolic effects and increases liver expression of activating transcription factor 4 (ATF4) and downstream targets with anti‐contractile ...

Sequential Accumulation of ‘Driver’ Pathway Mutations Induces the Upregulation of Hydrogen-Sulfide-Producing Enzymes in Human Colonic Epithelial Cell Organoids

open access: yesAntioxidants, 2022
Recently, a CRISPR-Cas9 genome-editing system was developed with introduced sequential ‘driver’ mutations in the WNT, MAPK, TGF-β, TP53 and PI3K pathways into organoids derived from normal human intestinal epithelial cells.

Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]

open access: yes, 2019
Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

3-Mercaptopyruvate sulfurtransferase disruption in dermal fibroblasts facilitates adipogenic trans-differentiation

open access: yesExperimental Cell Research, 2019
Transitioning from a differentiated state to a higher-order of plasticity, by partial rather than full reactivation of pluripotency genes, might be a better approach in regenerative medicine. Hydrogen sulfide plays a crucial role in the maintenance and differentiation of mesenchymal stem cells (MSC) that have the potential to differentiate to a diverse

Sulfur Administration in Fe–S Cluster Homeostasis

open access: yesAntioxidants, 2021
Mitochondria are the key organelles of Fe–S cluster synthesis. They contain the enzyme cysteine desulfurase, a scaffold protein, iron and electron donors, and specific chaperons all required for the formation of Fe–S clusters.
