ProteomicsSupersulphide airway protection in viral and chronic lung diseases
Supersulphides (inorganic and organic sulphides with sulphur catenation) manifest diverse physiological functions. These supersulphides are mainly generated from mitochondrial cysteinyl-tRNA synthetase (CARS2) that functions as a principal cysteine persulphide synthase (CPERS). Here we found power...

ProteomicsPolysulfur-based bulking of dynamin-related protein 1 prevents ischemic sulfide catabolism and heart failure
The presence of redox-active molecules containing catenated sulfur atoms (supersulfide) in living organisms has led to a review of the concepts of redox biology and its translational strategy. Glutathione (GSH) is the body’s primary detoxifier and antioxidant, and its oxidized form (GSSG) has been c...

ProteomicsMammals produce cyclo-octasulfur to suppress lipid peroxidation and ferroptosis
This dataset contains LC-ESI-Q-TOF tandem mass spectrometry data acquired to examine the protein composition of lipid droplets isolated from differentiated mouse 3T3-L1 adipocytes. Lipid droplet-associated proteins were delipidated, reduced, alkylated, and digested with trypsin before analysis by da...

Proteomics2H-Thiopyran-2-Thione Sulfine, a Compound For Converting H2S to HSOH/H2S2 and Increasing Intracellular Sulfane Sulfur Levels
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 suitable donors to produce these species. Herein...
