Epidemiological Evaluation of Neuter Status, Sex, and Breed in Dogs With Cystine Uroliths [PDF]

Journal of Veterinary Internal Medicine
Background The majority of cystine uroliths occur in intact male dogs. Androgen‐dependent (Type III) cystinuria is considered the most common cause. Objectives Identify dog breeds in which castration is likely to decrease the risk of cystine uroliths ...

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

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 ...

The mTORC1-mediated activation of ATF4 promotes protein and glutathione synthesis downstream of growth signals

eLife, 2021
The mechanistic target of rapamycin complex 1 (mTORC1) stimulates a coordinated anabolic program in response to growth-promoting signals. Paradoxically, recent studies indicate that mTORC1 can activate the transcription factor ATF4 through mechanisms ...

Production of recombinant human xCT (SLC7A11) and reconstitution in proteoliposomes for functional studies

Frontiers in Physiology, 2022
The plasma membrane transporter xCT belongs to the SLC7 family and has the physiological role of mediating the exchange of glutamate and cystine across the cell plasma membrane, being crucial for redox control.

Cysteines and Disulfide Bonds as Structure-Forming Units: Insights From Different Domains of Life and the Potential for Characterization by NMR

Frontiers in Chemistry, 2020
Disulfide bridges establish a fundamental element in the molecular architecture of proteins and peptides which are involved e.g., in basic biological processes or acting as toxins. NMR spectroscopy is one method to characterize the structure of bioactive

Uptake of L-cystine via an ABC transporter contributes defense of oxidative stress in the L-cystine export-dependent manner in Escherichia coli. [PDF]

PLoS ONE, 2015
Intracellular thiols like L-cystine and L-cystine play a critical role in the regulation of cellular processes. Here we show that Escherichia coli has two L-cystine transporters, the symporter YdjN and the ATP-binding cassette importer FliY-YecSC.
