Proteome-wide analysis of cysteine oxidation reveals metabolic sensitivity to redox stress [PDF]

open access: yesNature Communications, 2018
Reactive oxygen species (ROS) are increasingly recognised as important signalling molecules through oxidation of protein cysteine residues. Comprehensive identification of redox-regulated proteins and pathways is crucial to understand ROS-mediated events.

Extracellular cysteine in connexins: Role as redox sensors [PDF]

open access: yesFrontiers in Physiology, 2016
Indexación: Scopus.Connexin-based channels comprise hemichannels and gap junction channels. The opening of hemichannels allow for the flux of ions and molecules from the extracellular space into the cell and vice versa.

50 shades of oxidative stress: A state-specific cysteine redox pattern hypothesis

open access: yesRedox Biology, 2023
Oxidative stress is biochemically complex. Like primary colours, specific reactive oxygen species (ROS) and antioxidant inputs can be mixed to create unique “shades” of oxidative stress.

MYCN mediates cysteine addiction and sensitizes neuroblastoma to ferroptosis

open access: yesNature Cancer, 2022
Aberrant expression of MYC transcription factor family members predicts poor clinical outcome in many human cancers. Oncogenic MYC profoundly alters metabolism and mediates an antioxidant response to maintain redox balance. Here we show that MYCN induces

KEAP1, a cysteine-based sensor and a drug target for the prevention and treatment of chronic disease [PDF]

open access: yesOpen Biology, 2020
Redox imbalance and persistent inflammation are the underlying causes of most chronic diseases. Mammalian cells have evolved elaborate mechanisms for restoring redox homeostasis and resolving acute inflammatory responses.

Cysteine Oxidation in Proteins: Structure, Biophysics, and Simulation

open access: yesBiochemistry, 2022
Cysteine side chains can exist in distinct oxidation states depending on the pH and redox potential of the environment, and cysteine oxidation plays important yet complex regulatory roles.

Organic-to-Aqueous Phase Transfer of Alloyed AgInS2-ZnS Nanocrystals Using Simple Hydrophilic Ligands: Comparison of 11-Mercaptoundecanoic Acid, Dihydrolipoic Acid and Cysteine

open access: yesNanomaterials, 2021
The exchange of primary hydrophobic ligands for hydrophilic ones was studied for two types of alloyed AgInS2-ZnS nanocrystals differing in composition and by consequence exhibiting two different emission colors: red (R) and green (G).

Stoichiometric Thiol Redox Proteomics for Quantifying Cellular Responses to Perturbations

open access: yesAntioxidants, 2021
Post-translational modifications regulate the structure and function of proteins that can result in changes to the activity of different pathways. These include modifications altering the redox state of thiol groups on protein cysteine residues, which ...

The Capacity to Produce Hydrogen Sulfide (H2S) via Cysteine Degradation Is Ubiquitous in the Human Gut Microbiome

open access: yesbioRxiv, 2021
As one of the three mammalian gasotransmitters, hydrogen sulfide (H2S) plays a major role in maintaining physiological homeostasis. Endogenously produced H2S plays numerous beneficial roles including mediating vasodilation and conferring neuroprotection.

How the Competition for Cysteine May Promote Infection of SARS-CoV-2 by Triggering Oxidative Stress

open access: yesAntioxidants, 2023
SARS-CoV-2 induces a broad range of clinical manifestations. Besides the main receptor, ACE2, other putative receptors and co-receptors have been described and could become genuinely relevant to explain the different tropism manifested by new variants ...
