Adaptive Responses to Electrophilic Stress and Reactive Sulfur Species as their Regulator Molecules [PDF]

, 2019
We are exposed to numerous xenobiotic electrophiles on a daily basis through the environment, lifestyle, and dietary habits. Although such reactive species have been associated with detrimental effects, recent accumulated evidence indicates that ...

2H-Thiopyran-2-thione sulfine, a compound for converting H2S to HSOH/H2S2 and increasing intracellular sulfane sulfur levels

Nature Communications
Reactive sulfane sulfur species such as persulfides (RSSH) and H2S2 are important redox regulators and closely linked to H2S signaling. However, the study of these species is still challenging due to their instability, high reactivity, and the lack of ...

The Role of Hydrogen Sulfide in the Regulation of the Pulmonary Vasculature in Health and Disease

Antioxidants
The gasotransmitter hydrogen sulfide (H2S; also termed sulfide) generally acts as a vasodilator in the systemic vasculature but causes a paradoxical constriction of pulmonary arteries (PAs).

Versatile roles of cysteine persulfides in tumor biology

Current 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.

Unique response of polysulfide in serum albumin to oxidative stress

Scientific Reports
Supersulfide species have been identified as molecules that have catenated sulfur atoms as persulfides (R-SSH) and polysulfides (R-SSnH). The physiological activities of intracellular supersulfides have been widely studied, but little is known about the ...

Thiosulphate sulfurtransferase: Biological roles and therapeutic potential

Redox Biology
Mitochondria are central to eukaryotic cell function, driving energy production, intermediary metabolism, and cellular homeostasis. Dysregulation of mitochondrial function often results in oxidative stress, a hallmark of numerous diseases, underscoring ...
