Abstract:
Cystinosis is an autosomal recessive metabolic disease that belongs to the family of lysosomal storage disorders. The gene involved is the CTNS gene that encodes cystinosin, a seven-transmembrane domain lysosomal protein, which is a proton-driven cystine transporter. Cystinosis is characterized by the lysosomal accumulation of cystine, a dimer of cysteine, in all the cells of the body leading to multi-organ failure, including the failure of the kidney, eye, thyroid, muscle, and pancreas, and eventually causing premature death in early adulthood. The current treatment is the drug cysteamine, wh

Abstract:
In contrast to the molecular etiology of autonomously functioning thyroid nodules, the molecular cause of cold thyroid nodules (CTNs), their benign, functional inactive counterparts, are so far largely unknown. Because of the partially dedifferentiated phenotype of CTNs, alterations in signaling cascades that favor proliferation, but not differentiation, are likely candidates for tumor induction and progression. The importance of RAS mutations for the development of benign nodules with follicular histology is still in question. However, differentially expressed genes in the context of their si

Abstract:
Cystinosis is a rare, autosomal recessive, lysosomal storage disease caused by mutations in the gene CTNS, leading to cystine accumulation in the lysosomes. While cysteamine lowers the cystine levels, it does not cure the disease, suggesting that CTNS exerts additional functions besides cystine transport. This study investigated the impact of infantile and juvenile CTNS mutations with discrepant genotype/phenotype correlations on CTNS expression, and subcellular localisation and function in clinically relevant cystinosis cell models to better understand the link between genotype and CTNS funct

Abstract:
Cystinosis is a rare autosomal recessive storage disease that occurs as a result of deficiency of the cystinosine carrier protein caused by mutations in the CTNS gene, which encodes cystinosine, a cysteine carrier in lysosomal membranes. Our study aimed to determine cystinosis gene mutations and their geographical distribution in Turkish pediatric patients with cystinosis. Two brothers and one girl with infantile nephropathic and ocular cystinosis were included in the study. Molecular analyzes included initial multiplex polymerase chain reaction (PCR) to identify a 57 kb deletion in CTNS and a

Abstract:
Mice lacking the functional cystinosin gene (Ctns−/−), a model of infantile nephropathic cystinosis (INC), exhibit the cachexia phenotype with adipose tissue browning and muscle wasting. Elevated leptin signaling is an important cause of chronic kidney disease-associated cachexia. The pegylated leptin receptor antagonist (PLA) binds to but does not activate the leptin receptor. We tested the efficacy of this PLA in Ctns−/− mice. We treated 12-month-old Ctns−/− mice and control mice with PLA (7 mg/kg/day, IP) or saline as a vehicle for 28 days.

Abstract Background Cystinosis is a rare autosomal-recessive disorder caused by a defective transport of cystine across the lysosomal membrane. Previous studies have mapped cystinosis to the CTNS gene which is located on chromosome 17p13, and various CTNS mutations have been identified to correlate them with this disease. Methods We analyzed six patients from five unrelated families who were diagnosed with cystinosis in our hospital. We described the diagnostic procedures for all the patients and proposed alternative therapies for cystinosis patients instead of using cysteamine, an orphan drug

Abstract:
Nephropathic cystinosis is a rare autosomal recessive disorder caused by a deletion mapped to chromosome 17p13. The gene codes for a protein, cystinosin (CTNS), a lysosomal membrane transporter protein. When the CTNS gene is inactivated, the amino acid cystine cannot cross the lysosomal membrane and accumulates in lysosomes. Thus, cystinosis is a lysosomal storage disease. The accumulated cystine forms crystals that can cause damage to multiple organs. Cystinosis is thought to occur with an incidence of 1 in 100,000 live births, although accurate numbers are difficult to obtain because the dis
