One- and Two-Photon-Activated Cysteine Persulfide Donors for Biological Targeting

open access: yes, 2019
Persulfides have been considered as potential signaling compounds similar to the H2S in “S-persulfidation”, a sulfur-mediated redox cycle. The research of this sulfur-mediated species is hindered because of the lack of efficient persulfide donors.

Cars2‐Mediated Cysteine Catabolism Drives Brown Fat Development and Thermogenesis Through Persulfidating EBF2

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

Transpersulfidation or H2S Release? Understanding the Landscape of Persulfide Chemical Biology

open access: yes
Persulfides (RSSH) are biologically important reactive sulfur species that are endogenously produced, protect key cysteine residues from irreversible oxidation, and are important intermediates during different enzymatic processes.

Histone Deacetylase 9 Gene Deletion Ameliorates Aging‐Related Adipose Tissue Senescence and Mitochondrial Dysfunction in Mice

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Cellular senescence and mitochondrial dysfunction disrupt adipose tissue homeostasis during aging, but mechanisms remain unclear. HDAC9 expression increases with age in mouse adipose tissue and Hdac9 knockout mice showed reduced fat mass, senescence markers, and enhanced mitochondrial gene expression, respiration, and thiosulfate sulfurtransferase (Tst)

Mammalian frataxin directly enhances sulfur transfer of NFS1 persulfide to both ISCU and free thiols.

open access: yes, 2014
International audienceFriedreich's ataxia is a severe neurodegenerative disease caused by the decreased expression of frataxin, a mitochondrial protein that stimulates iron-sulfur (Fe-S) cluster biogenesis.

Therapeutic Gases in Biomedicine: Updates on Nitric Oxide and Beyond

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
Therapeutic gases, including NO, CO, H2S, H2, CO2, O2, and Xe, play vital roles in cellular signaling and repair. This review highlights the emerging carriers and delivery systems that enable controlled, localized gas release for diagnostic and therapeutic applications.

Increased intracellular H2S levels enhance iron uptake in Escherichia coli

open access: yesmBio
We investigated the impact of intracellular hydrogen sulfide (H2S) hyperaccumulation on the transcriptome of Escherichia coli. The wild-type (WT) strain overexpressing mstA, encoding 3-mercaptopyruvate sulfur transferase, produced significantly higher ...

Clonal Stabilization Reveals a DAO/3MST‐Expressing MDCK Subpopulation With Robust d‐Cysteine‐Mediated H2S Production

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
A subpopulation of MDCK (NBL‐2) cells, an epithelial cell line derived from the normal kidney, expresses DAO and 3MST. The DAO/3MST‐expressing cells are progressively eliminated during passaging; however, clonal isolation enables the establishment of sublines that maintain stable H2S production. Clonal cells co‐expressing DAO and 3MST therefore provide

Thiosulfoxide (Sulfane) Sulfur: New Chemistry and New Regulatory Roles in Biology

open access: yesMolecules, 2014
The understanding of sulfur bonding is undergoing change. Old theories on hypervalency of sulfur and the nature of the chalcogen-chalcogen bond are now questioned.

Persulfide Formation Mediates Cysteine and Homocysteine Biosynthesis in Methanosarcina acetivorans

open access: yes, 2017
The mechanisms of sulfur uptake and trafficking in methanogens inhabiting sulfidic environments are highly distinctive. In aerobes, sulfur transfers between proteins occur via persulfide relay, but direct evidence for persulfides in methanogens has been ...
