Iron‐Based Materials for Advanced Lithium/Sodium‐Ion Batteries

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
This Review examines iron‐based anode materials for lithium‐ and sodium‐ion batteries, emphasizing how phase chemistry (sulfides, oxides, and metal–organic framework (MOF)‐derived compounds), multiscale structural engineering, and interface regulation collectively address volume expansion, conductivity limitations, and cycling instability, while ...

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

Sulfide-Responsive Transcription Control in Escherichia coli

open access: yesMicroorganisms
To elucidate the mechanism of large-scale transcriptional changes dependent on sulfide in Escherichia coli, a large-scale RNA-sequencing analysis was performed on wild-type and sulfide-responsive transcription factor YgaV deletion mutants grown under ...

Biosynthesis of Sulfur-Containing tRNA Modifications: A Comparison of Bacterial, Archaeal, and Eukaryotic Pathways

open access: yesBiomolecules, 2017
Post-translational tRNA modifications have very broad diversity and are present in all domains of life. They are important for proper tRNA functions.

Self-S-sulfonation in a bacterial persulfide dioxygenase mediates thiol persulfide detoxification

open access: yes
A ubiquitous class of non-heme Fe(II) enzymes, the persulfide dioxygenases (PDOs), provide protection against hydrogen sulfide (H2S) poisoning. The PDO in humans is a single-domain enzyme, while bacterial PDOs, such as CstB of Staphylococcus aureus, are often fused to a sulfurtransferase (rhodanese) module.

Mining proteomes for zinc finger persulfidation

open access: yesRSC Chemical Biology
A meta-analysis of 22 persulfide-specific proteomics datasets reveals widespread persulfidation of zinc finger proteins across various species, highlighting the role of persulfidation as an important post-translational modification.

Ultrasensitive bioorthogonal probes for selective discrimination of trace H2S2/H2Sn in sulfide-competitive contexts

open access: yesActa Pharmaceutica Sinica B
Hydrogen persulfide/polysulfides (H2S2/H2Sn), as an oxidized derivative of hydrogen sulfide (H2S), is capable of directly inducing the S-persulfidation of cysteine residues, thereby modulating the activity of relevant enzymes.

Polysulfide and persulfide-mediated activation of the PERK-eIF2α-ATF4 pathway increases Sestrin2 expression and reduces methylglyoxal toxicity

open access: yesRedox Biology
Unfolded protein response (UPR) is activated in cells under endoplasmic reticulum (ER) stress. One sensor protein involved in this response is PERK, which is activated through its redox-dependent oligomerization.

Versatile roles of cysteine persulfides in tumor biology

open access: yesCurrent Opinion in Chemical Biology
Rewiring the transsulfuration pathway is recognized as a rapid adaptive metabolic response to environmental conditions in cancer cells to support their increased cysteine demand and to produce Reactive Sulfur Species (RSS) including hydrogen sulfide (H2S) and cysteine persulfide.
