The Therapeutic Potential of Supersulfides in Oxidative Stress-Related Diseases
Oxidation-reduction (redox) reactions are fundamental to sustaining life, with reactive oxygen and nitrogen species playing pivotal roles in cellular signaling and homeostasis. However, excessive oxidative stress disrupts redox balance, contributing to a

Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

Thiosulfonate‐Derived BODIPY “Stick and Glue” Strategy for Fluorescent Thiol Labeling
We present a powerful photochemical strategy for converting disulfide bonds into stable thioether linkages via a [1,2]‐sigmatropic rearrangement. By integrating this reaction into traditional methanethiosulfonate‐based thiol labeling, we enable light‐triggered stabilization of peptide and protein conjugates with enhanced robustness and versatility ...

Alcohol metabolism induces structural instability of iron‐sulfur clusters through ROS‐mediated oxidative damage and direct covalent modification of acetaldehyde. The iron‐sulfur cluster deficiency drives metabolic reprogramming by inactivating aconitase, accumulating succinate, and impairing tRNA thiolation, thereby promoting hepatic steatosis ...

Formation of persulfide groups in alkaline treated insulin [PDF]
Alkaline treatment of disulfidecontaining proteins is known to produce a number of unusual compounds related with the degradation of the cystinyl residues. Lanthionine [l] and lysinoalanine [2] are among the products identified with certainly, while dehydroala- nine [2] , thiocysteine [3,4] , cysteine sulfenic acid [S] and other products are supposed ...

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

MAPK Inhibitor‐Tolerant Persister Cells in Melanoma: Mechanisms and Therapeutic Vulnerabilities
Melanoma response to MAPK inhibition progresses from drug‐sensitive cells to drug‐tolerant persister states, which enable survival through adaptive signaling, metabolic rewiring, and phenotypic plasticity. These persister cells serve as an intermediate reservoir from which resistant tumors ultimately emerge. ABSTRACT Though major advancements have been

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.

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)
