Cystine nephrolithiasis: contemporary approaches to patient management

open access: yesВестник урологии
Introduction. Cystinuria is a rare genetic disorder characterised by a markedly elevated concentration of cystine in the urine. Due to the low solubility of cystine in urine, patients with cystinuria face a lifelong increased risk of urinary stone ...

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Inducing disulfidptosis in tumors:potential pathways and significance

open access: yesMedComm
Regulated cell death (RCD) is crucial for the elimination of abnormal cells. In recent years, strategies aimed at inducing RCD, particularly apoptosis, have become increasingly important in cancer therapy.

GSH as an A‐A Type Allosteric Activator of PKM2: Modulating Cancer Cell Homeostasis and Ferroptosis Susceptibility

open access: yesAdvanced Science, EarlyView.
Glutathione (GSH) defines oxidative balance, but can it directly tune central metabolism? The research reveals that GSH binds and potently activates pyruvate kniase M2 (PKM2), rewiring glycolysis and dictating ferroptosis sensitivity. Combining GSH depletion with PKM2 activation triggers mitochondrial damage and lipid peroxidation, profoundly ...

Quantification of Single‐Cell Cysteine Using an Electrochemical Nanosensor for Predicting Tumor Disulfidptosis Susceptibility

open access: yesAdvanced Science, EarlyView.
Cysteine attracts interest due to its unique electrochemical activity and emerging relationship with disulfidptosis. This study develops a new electrochemical nanosensor, which represents the first of its kind capable of detecting intracellular cysteine for various types of tumor cells and primary tumor cells in mice to evaluate disulfidptosis ...

Metabolism‐Regulating Nanomedicines for Cancer Therapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review highlights metabolism‐regulating nanomedicines designed to target glycolytic, lipid, amino acid, and nucleotide pathways in tumors. By incorporating metabolism‐regulating agents into versatile nanocarriers such as liposomes, micelles, dendrimers, and engineered bacteria, these platforms achieve targeted delivery, controlled release ...

p53 Suppresses Metabolic Stress-Induced Ferroptosis in Cancer Cells

open access: yesCell Reports, 2018
How cancer cells respond to nutrient deprivation remains poorly understood. In certain cancer cells, deprivation of cystine induces a non-apoptotic, iron-dependent form of cell death termed ferroptosis.

Low‐Level Arsenic Removal from Drinking Water

open access: yesGlobal 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.

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

open access: yesAnimal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...
