ethylmaleimide and Cystinosis

ethylmaleimide has been researched along with Cystinosis in 9 studies

Ethylmaleimide: A sulfhydryl reagent that is widely used in experimental biochemical studies.

Cystinosis: A metabolic disease characterized by the defective transport of CYSTINE across the lysosomal membrane due to mutation of a membrane protein cystinosin. This results in cystine accumulation and crystallization in the cells causing widespread tissue damage. In the KIDNEY, nephropathic cystinosis is a common cause of RENAL FANCONI SYNDROME.

"The activity of a cystine transport system in lysosomes prepared from the leukocytes of patients with cystinosis was found to be deficient."7.66Cystine transport is defective in isolated leukocyte lysosomes from patients with cystinosis. ( Bashan, N; Bernardini, I; Gahl, WA; Schulman, JD; Tietze, F, 1982)
"In patients with cystinosis, the concentration of free cystine in leukocytes was 80 times greater than normal, and six times the normal content for their parents."7.64Increased cystine in leukocytes from individuals homozygous and heterozygous for cystinosis. ( Bradley, K; Schneider, JA; Seegmiller, JE, 1967)
" The detection limit for the determination of cystine is adequate to measure cystine in leukocytes and cultured fibroblasts for diagnosis of cystinosis and monitoring treatment with cysteamine."3.70New method for determining cystine in leukocytes and fibroblasts.
