Chemical compositional studies of erythrocyte membranes in Duchenne muscular dystrophy. 1978

D V Godin, and M A Bridges, and P J MacLeod

Erythrocytes from patients with Duchenne muscular dystrophy (DMD) are known to possess a number of structural and functional abnormalities, including an increased osmotic fragility and potassium permeability, a decreased deformability and altered electrophoretic behaviour. To explore the possible chemical basis of these changes, the compositional properties of erythrocyte membranes from patients with DMD and a number of suspected carriers for this disorder have been investigated. Quantitative analyses of membrane cholesterol, sialic acid and major phospholipid classes were normal in both groups of individuals and no alterations in the arrangement of membrane amino and sulfhydryl groups could be detected. It is suggested that increased levels of cellular calcium, possibly occurring as the result of a defect in active calcium extrusion, could account for the structural and functional abnormalities of erythrocytes in DMD.

D009136	Muscular Dystrophies	A heterogeneous group of inherited MYOPATHIES, characterized by wasting and weakness of the SKELETAL MUSCLE. They are categorized by the sites of MUSCLE WEAKNESS; AGE OF ONSET; and INHERITANCE PATTERNS.

D009996	Osmotic Fragility	RED BLOOD CELL sensitivity to change in OSMOTIC PRESSURE. When exposed to a hypotonic concentration of sodium in a solution, red cells take in more water, swell until the capacity of the cell membrane is exceeded, and burst.	Saline Fragility,Fragility, Osmotic,Fragility, Saline
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.
