To study ganglioside distribution within subcellular components and test the hypothesis that they are localized at the nerve ending, microsomes and synaptic plasma membranes were isolated from young adult rat brains and compared with respect to ganglioside composition. These were shown to be heterogeneous preparations by fractionation on a discontinuous(More)
A 46-year-old man, the son of normal nonconsanguinous parents, had a rare progressive neurological illness that began in midlife and was characterized by seizures, buccolingual dyskinesia, orofacial tics, choreiform movements, areflexia, and neurogenic muscle atrophy. Acanthocytosis was present. The serum creatine kinase level was elevated and(More)
The ganglioside composition of calf aortic smooth muscle cells, cultured in the presence and absence of ascorbate, was analyzed. Previous work has shown that ascorbate supplementation leads to the formation of an extracellular matrix consisting primarily of collagen and that this matrix influences the biosynthetic capabilities of the cell. Cell cultures(More)
