Cystinuria in an Australian Cattle Dog Family—A Seemingly Androgen-Associated Autosomal Dominant Trait [PDF]

Veterinary Sciences
In Australian Cattle Dogs (AUCDs), cystinuria was reported to be an autosomal dominant trait caused by a 6 bp deletion in the SLC3A1 gene (type II-A). Here we report an androgen association in this breed.

Coenzyme A mitigates cystine-deprivation-induced ferroptosis by suppressing the iron-starvation response. [PDF]

FEBS J
Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

Redox State of Glutathione and Cysteine in Plasma Following Acute Stroke [PDF]

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 ...

Augmented Cystine–Glutamate Exchange by Pituitary Adenylate Cyclase-activating Polypeptide Signaling via the VPAC1 Receptor [PDF]

, 2014
In the central nervous system, cystine import in exchange for glutamate through system xc- is critical for the production of the antioxidant glutathione by astrocytes, as well as the maintenance of extracellular glutamate. Therefore, regulation of system

Intracellular Distribution of Cystine in Cystine-Loaded Proximal Tubules [PDF]

Pediatric Research, 1994
Cellular cystine loading with cystine dimethyl ester has been shown to inhibit transport in proximal convoluted tubules perfused in vitro and decrease the rate of oxygen consumption in suspensions of proximal tubules. The present study was designed to examine the intracellular distribution of cystine in this model of the Fanconi syndrome of cystinosis ...

Urinary felinine excretion in intact male cats is increased by dietary cystine [PDF]

, 2008
Felinine is a branched-chain sulfur amino acid present in the urine of certain Felidae, including domestic cats. The objective of the present study was to determine if additional cystine and/or dietary N would increase felinine and N-acetylfelinine ...

A mTORC1-mediated cyst(e)ine sensing mechanism governing GPX4 synthesis and ferroptosis

Molecular & Cellular Oncology, 2021
Ferroptosis is a cell death mechanism triggered by lipid peroxidation. Our recent study linked cyst(e)ine availability with glutathione peroxidase 4 (GPX4) protein synthesis and ferroptosis mitigation via a Rag-mechanistic target of rapamycin complex 1 ...

The effect of pressure on the crystal structure of hexagonal L-cystine [PDF]

, 2005
The crystal structure of hexagonal L-cystine has been determined at room temperature at pressures between 0.4 and 3.7 GPa; unit-cell dimensions were measured up to 6.4 GPa. The structure of this phase consists of molecules in their zwitterionic form, and
