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.

Pharmacological inhibition of cystine–glutamate exchange induces endoplasmic reticulum stress and ferroptosis

eLife, 2014
Exchange of extracellular cystine for intracellular glutamate by the antiporter system xc− is implicated in numerous pathologies. Pharmacological agents that inhibit system xc− activity with high potency have long been sought, but have remained elusive ...

Gas-Phase Fragmentation Reactions of Protonated Cystine using High-Resolution Tandem Mass Spectrometry

Molecules, 2019
Cystine is an important biomolecule in living systems. Although collision-induced dissociation (CID)-based tandem mass spectrometry (MS/MS) is commonly applied for identification and quantification of cystine in both biomedical and nutritional studies ...

Local Guidance on the Management of Nephropathic Cystinosis in the Gulf Cooperation Council (GCC) Region

Children
Cystinosis is a rare systemic disease characterized by the accumulation of cystine in tissues, leading to multi-organ damage. Infantile nephropathic cystinosis is the dominant and severe form of cystinosis with critical renal manifestations that require ...

Scaffolding of Cystine‐Stabilized Miniproteins

ChemistrySelect, 2016
Abstract Biomolecular scaffolds were engineered by genetically fusing robust miniproteins in a sequence, like a chain. By fusing these miniprotein chains to a teal fluorescent protein (TFP), an efficient strategy was devised for their production in E. coli.

Outcomes of Tiopronin and D-Penicillamine Therapy in Pediatric Cystinuria: A Clinical Comparison of Two Cases

Reports
Background and Clinical Significance: Cystinuria is the most common genetic cause of pediatric nephrolithiasis, characterized by impaired renal cystine reabsorption and resulting in increased urinary cystine excretion.

Selective, Simple and Economical Method for the Voltammetric Determination of Bi(III) in the presence Cystine in Non – Complexing Solution

E3S Web of Conferences, 2013
The simple and fast method for the determination of Bi(III) in non-complexing solution was proposed. The catalytic activity of cystine on Bi(III) ions electroreduction process were utilized.

Disruption of a cystine transporter downregulates expression of genes involved in sulfur regulation and cellular respiration

Biology Open, 2016
Cystine and cysteine are important molecules for pathways such as redox signaling and regulation, and thus identifying cellular deficits upon deletion of the Saccharomyces cerevisiae cystine transporter Ers1p allows for a further understanding of cystine

Canine Cystine Urolithiasis

Veterinary Clinics of North America: Small Animal Practice, 1986
Cystine uroliths form as a result of a complex metabolic disturbance in amino acid metabolism and transport. The inheritance of this disease is obscure because it does not follow a standard mendelian pattern. Uroliths are a vexing clinical problem because the recurrence rate is high.

Redox State of Glutathione and Cysteine in Plasma Following Acute Stroke

Antioxidants
Ischemic stroke is a major cause of long-term disability and death, with oxidative stress contributing substantially to post-ischemic injury. Reperfusion restores oxygen supply but simultaneously increases reactive oxygen species (ROS), amplifying ...
