Adaptation of Candida albicans to Reactive Sulfur Species. [PDF]

open access: yesGenetics, 2017
Abstract Candida albicans is an opportunistic fungal pathogen that is highly resistant to different oxidative stresses. How reactive sulfur species (RSS) such as sulfite regulate gene expression and the role of the transcription factor Zcf2 and the sulfite exporter Ssu1 in such responses are not known. Here, we show that C.

Catalase as a sulfide-sulfur oxido-reductase: An ancient (and modern?) regulator of reactive sulfur species (RSS) [PDF]

open access: yesRedox Biology, 2017
Catalase is well-known as an antioxidant dismutating H2O2 to O2 and H2O. However, catalases evolved when metabolism was largely sulfur-based, long before O2 and reactive oxygen species (ROS) became abundant, suggesting catalase metabolizes reactive ...

Redox signaling regulated by electrophiles and reactive sulfur species. [PDF]

open access: yesJ Clin Biochem Nutr, 2016
Redox signaling is a key modulator of oxidative stress induced by nonspecific insults of biological molecules generated by reactive oxygen species. Current redox biology is revisiting the traditional concept of oxidative stress, such that toxic effects of reactive oxygen species are protected by diverse antioxidant systems upregulated by oxidative ...

Sulfide Homeostasis and Nitroxyl Intersect via Formation of Reactive Sulfur Species in Staphylococcus aureus [PDF]

open access: yesmSphere, 2017
Staphylococcus aureus is a commensal human pathogen and a major cause of nosocomial infections. As gaseous signaling molecules, endogenous hydrogen sulfide (H2S) and nitric oxide (NO·) protect S.

Reactive Sulfur Species in Human Diseases

open access: yesAntioxidants & Redox Signaling, 2023
Significance: Reactive sulfur species (RSS) have been recently recognized as redox molecules no less important than reactive oxygen species or reactive nitrogen species. They possess regulatory and protective properties and are involved in various metabolic processes, thereby contributing to the maintenance of human health.

Recent Development of the Molecular and Cellular Mechanisms of Hydrogen Sulfide Gasotransmitter

open access: yesAntioxidants, 2022
Hydrogen sulfide has been recently identified as the third biological gasotransmitter, along with the more well studied nitric oxide (NO) and carbon monoxide (CO). Intensive studies on its potential as a therapeutic agent for cardiovascular, inflammatory,

Rhodanese Rdl2 produces reactive sulfur species to protect mitochondria from reactive oxygen species

open access: yesFree Radical Biology and Medicine, 2021
Mitochondria damage is related to a broad spectrum of pathologies including Alzheimer's, Parkinson's disease, and carcinogenesis. Recently, it has been found that reactive sulfur species (RSS) has a close connection with mitochondrial health.

Juggling with reactive oxygen species and antioxidant defense system – A coping mechanism under salt stress

open access: yesPlant Stress, 2022
Even under optimal conditions many metabolic processes produce ROS like superoxide anion (O2.-), hydrogen peroxide (H2O2) and hydroxyl radicals (OH⋅), particularly in chloroplast and mitochondria.
