Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

Advanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

NRF2 signalling in cytoprotection and metabolism

British Journal of Pharmacology, EarlyView., 2023
The KEAP1‐NRF2 system plays a central role in cytoprotection in defence mechanisms against oxidative stress. The KEAP1‐NRF2 system has been regarded as a sulfur‐utilizing cytoprotective mechanism, because KEAP1 serves as a biosensor for electrophiles by using its reactive thiols and NRF2 is a transcriptional factor regulating genes involved in sulfur ...

Low‐Level Arsenic Removal from Drinking Water

Global Challenges, 2019
The reported ability of cysteine and cystine to bind typical arsenic oxy‐ions in water is used as a basis for a study of the potential for using a surfactant with a cysteine head‐group for selective arsenic binding and removal in an ion flotation process.

A Cytotoxic, Co-operative Interaction Between Energy Deprivation and Glutamate Release From System x\u3csub\u3ec\u3c/sub\u3e\u3csup\u3e−\u3c/sup\u3e Mediates Aglycemic Neuronal Cell Death [PDF]

, 2015
The astrocyte cystine/glutamate antiporter (system xc−) contributes substantially to the excitotoxic neuronal cell death facilitated by glucose deprivation. The purpose of this study was to determine the mechanism by which this occurred.

Screening, large-scale production, and structure-based classification for cystine-dense peptides

Nature Structural & Molecular Biology, 2018
Peptides folded through interwoven disulfides display extreme biochemical properties and unique medicinal potential. However, their exploitation has been hampered by the limited amounts isolatable from natural sources and the expense of chemical ...

Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

Advanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Supersulfide biology and translational medicine for disease control

British Journal of Pharmacology, EarlyView., 2023
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Sulfur Amino Acids in Diet-induced Fatty Liver: A New Perspective Based on Recent Findings

Molecules, 2014
The relationship of sulfur amino acids to diet-induced fatty liver was established 80 years ago, with cystine promoting the condition and methionine preventing it.

EGFR: New Insights on Its Activation and Mutation in Tumor and Tumor Immunotherapy

Advanced Science, EarlyView.
This review provides new perspectives on EGFR's activation, mutations, and their impact on tumor immunotherapy. It summarizes how EGFR is activated and the current EGFR targeting strategy, evaluates their clinical outcomes in combination with immunotherapy, highlighting differential responses in tumors with EGFR wild‐type and different mutants.

Crosstalk between cystine and glutathione is critical for the regulation of amino acid signaling pathways and ferroptosis

Scientific Reports, 2016
Although essential amino acids regulate mechanistic target of rapamycin complex 1 (mTORC1) and the integrated stress response (ISR), the role of cysteine is unknown.
