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

Redox 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.

Role of sulfane sulfur species in elemental tellurium nanorod formation in mammalian cells

Redox Biochemistry and Chemistry
Tellurium (Te) is an industrially useful element but its oxyanions, such as tellurite and tellurate, are naturally occurring chemical forms that can become a potential source of toxicity to humans and animals.

Preliminary exploration of polysulfide detection in wine using fluorescent probe SSP4 and A-TEEM spectroscopy

OENO One
Polysulfides have emerged as a novel class of sulfur compounds in wine that continue to be explored and characterised, but analytical challenges still remain.

Terrestrial iron sulfide minerals induce distinct regulation of intracellular redox homeostasis and iron assimilation

Ecotoxicology and Environmental Safety
Repeated exposure to airborne terrestrial natural minerals may cause pneumoconiosis and lung cancer, among which iron sulfide is identified as an aggravating factor.

Oxidative Stress and Iron Addiction: A Comparative Study of 1321N1 Astrocytoma and T98G Glioblastoma Cells with Differential Expression of L-Cysteine-Metabolizing Enzymes

Biomolecules
Gliomas are central nervous system primary tumors that are distinguished by heterogeneity, broad-based infiltration, and metabolic reprogramming that sustains proliferation, invasion, and therapy refractoriness.
