Oxidative Stress and Iron Addiction: A Comparative Study of 1321N1 Astrocytoma and T98G Glioblastoma Cells with Differential Expression of L-Cysteine-Metabolizing Enzymes [PDF]
BiomoleculesGliomas are central nervous system primary tumors that are distinguished by heterogeneity, broad-based infiltration, and metabolic reprogramming that sustains proliferation, invasion, and therapy refractoriness.

Modified cyclodextrins solubilize elemental sulfur in water and enable biological sulfane sulfur delivery. [PDF]
Chem Sci, 2020 Sulfane sulfur, or S 0 , is found in polysulfide and persulfide compounds in biology. We demonstrate that modified cyclodextrins can solubilize S 8 in water, increase its reactivity with biological nucleophiles, and enable delivery to live cells.

Synechococcus sp. PCC7002 Uses Peroxiredoxin to Cope with Reactive Sulfur Species Stress
mBio, 2022 Cyanobacteria are a widely distributed group of microorganisms in the ocean, and they often need to cope with the stress of reactive sulfur species, such as sulfide and sulfane sulfur.

New fluorescent probes for sulfane sulfurs and the application in bioimaging [PDF]
Chemical Science, 2013 A sulfane sulfur mediated benzodithiolone formation was developed. Based on this reaction, two fluorescent probes (SSP1 and SSP2) for the detection of sulfane sulfur species (persulfide, polysulfide, and elemental sulfur) were prepared and evaluated. The probes showed high selectivity and sensitivity to sulfane sulfurs.

Isotope dilution mass spectrometry for the quantification of sulfane sulfurs [PDF]
Free Radical Biology and Medicine, 2014 Sulfane sulfurs are one type of important reactive sulfur species. These molecules have unique reactivity that allows them to attach reversibly to other sulfur atoms and exhibit regulatory effects in diverse biological systems. Recent studies have suggested that sulfane sulfurs are involved in signal transduction processes regulated by hydrogen sulfide

The multifaceted roles of sulfane sulfur species in cancer-associated processes
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2021 Sulfane sulfur species comprise a variety of biologically relevant hydrogen sulfide (H2S)-derived species, including per- and poly-sulfidated low molecular weight compounds and proteins. A growing body of evidence suggests that H2S, currently recognized as a key signaling molecule in human physiology and pathophysiology, plays an important role in ...

Sulfane Sulfur Compounds as Source of Reappearance of Reductive Off-Odors in Wine
Fermentation, 2022 Reactive compounds with one or more sulfane sulfur atoms can be an important source of reductive off-odors in wine. These substances contain labile sulfur, which can participate in microbiological (enzymatic) and chemical transformations (including in ...

The conversion of H2S to sulfane sulfur [PDF]
Nature Reviews Molecular Cell Biology, 2012 In a recently published Review article (H2S signalling through protein sulfhydration and beyond. Nature Rev. Mol. Cell Biol. 13, 499–507 (2012))1, Paul and Snyder use the term 'sulfhydration' to define a protein modification involving hydrogen sulfide (H2S) in which “the sulfhydryl group of a reactive Cys is modified to an -SSH group”.
