Cystine storage in cultured myotubes from patients with nephropathic cystinosis.
Sorted muscle cells, cultured from a patient with nephropathic cystinosis, stored 100 times normal amounts of cystine. Subcellular fractionation and density-gradient centrifugation confirmed that the cystine was located in a lysosomal compartment. 2. Myoblasts from cystinotic patients in culture underwent fusion to myotubes in a normal fashion. 3. The free thiol cysteamine effectively depleted ...
متن کاملHigh cystine in platelets from patients with nephropathic cystinosis: a chemical, ultrastructural, and functional evaluation.
AIM To investigate the morphology and function of platelets in nephropathic cystinosis (NC). METHODS Seven patients (mean age, 6.5 years; SD, 20 months) with NC were investigated. Their platelets were examined by transmission electron microscopy (TEM) and the characteristics of the dense granules (DGs) were determined by mepacrine labelling and the uranaffin reaction. Bleeding time, turbidome...
متن کاملPulmonary dysfunction in adults with nephropathic cystinosis.
OBJECTIVE To characterize the pulmonary dysfunction in patients with nephropathic cystinosis after renal transplantation. DESIGN Cross-sectional analysis of consecutive adult patients. PATIENTS Twelve adult, nephropathic cystinosis patients and 3 adult, ocular, nonnephropathic cystinosis patients admitted to the National Institutes of Health Clinical Center. RESULTS The 12 nephropathic cy...
متن کاملInfantile nephropathic cystinosis.
INTRODUCTION Infantile nephropathic cystinosis (INC) is a metabolic disorder due to impaired carrier-mediated transport of cystine out of cellular lysosomes. OBJECTIVE To examine the prevalence and clinical characteristics of INC in paediatric patients with endstage renal disease (ESRD) in Serbia and give a recent statement of the disease. METHODS ESRD database of the Centre for Paediatric ...
متن کاملCorneal thickness in nephropathic cystinosis.
Cystinosis is a rare autosomal recessive metabolic disorder in which non-protein cystine accumulates within cellular lysosomes owing to a defect in lysosomal cystine transport. The pathognomonic ocular manifestation of cystinosis is the deposition of distinctive iridescent crystals in the cornea, not associated with any inflammatory response or recognised change in corneal function. We measured...
