The Role of Cysteine Residues in Redox Regulation and Protein Stability of Arabidopsis thaliana Starch Synthase 1. [PDF]

PLoS ONE, 2015
Starch biosynthesis in Arabidopsis thaliana is strictly regulated. In leaf extracts, starch synthase 1 (AtSS1) responds to the redox potential within a physiologically relevant range. This study presents data testing two main hypotheses: 1) that specific

1-Chloro-2,4-dinitrobenzene is an irreversible inhibitor of human thioredoxin reductase. Loss of thioredoxin disulfide reductase activity is accompanied by a large increase in NADPH oxidase activity.

The Journal of biological chemistry, 1995
Human thioredoxin reductase is a dimeric enzyme that catalyzes reduction of the disulfide in oxidized thioredoxin by a mechanism involving transfer of electrons from NADPH via FAD to a redox-active disulfide. 1-Chloro-2,4-dinitrobenzene (DNCB) is an alkylating agent used for depleting intracellular GSH and also showing distinct immunomodulatory ...

Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...

Nitric Oxide in Cancer: Mechanisms, Dual Role, and Therapeutic Strategies

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Nitric oxide exerts concentration‐dependent dual roles in cancer, functioning as either a tumor promoter or suppressor. This review comprehensively examines NO's multifaceted regulation of tumor biology, including S‐nitrosylation signaling, metabolic reprogramming, immunemodulation, and therapy resistance, and highlights emerging therapeutic strategies

How thioredoxin dissociates its mixed disulfide.

PLoS Computational Biology, 2009
The dissociation mechanism of the thioredoxin (Trx) mixed disulfide complexes is unknown and has been debated for more than twenty years. Specifically, opposing arguments for the activation of the nucleophilic cysteine as a thiolate during the ...

Edible Insect Allergens: An Emerging Food Safety Challenge

Sustainable Food Proteins, Volume 4, Issue 3, September 2026.
Allergic responses to edible insects arise via two main pathways: cross‐reactivity with homologous arthropod allergens and primary sensitization to edible insect proteins, both leading to IgE‐mediated immune activation. ABSTRACT Edible insects are increasingly promoted as sustainable protein sources; however, their allergenic potential remains a ...

Crystal Structure of the Apo-Form of NADPH-Dependent Thioredoxin Reductase from a Methane-Producing Archaeon

Antioxidants, 2018
The redox regulation of proteins via reversible dithiol/disulfide exchange reactions involves the thioredoxin system, which is composed of a reductant, a thioredoxin reductase (TR), and thioredoxin (Trx).

Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review

eFood, Volume 7, Issue 4, August 2026.
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

Monitoring the Effect of Tributyltin Salicylate and Propionate, Retinoid X Receptor Ligands, on Heat Shock Protein Expression in MDA‐MB‐231 Cells by MALDI MS/MS

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Organotin (IV) compounds are known to induce apoptosis via the intrinsic mitochondrial pathway, which is a key mechanism of effective anticancer therapy. Their ability to selectively promote apoptotic cell death highlights their potential as chemotherapeutic agents. In this study, the in vitro effects of two triorganotin compounds, tributyltin
