Abstract
Ganglioside compositions in the brains of the mutant mice quaking and shiverer were compared with those of their littermate controls, C57BL/6 and C3HSWV. Neither ganglioside content nor composition of shiverer brains differed from those of the control brains. Change in the ganglioside composition of the mutant brain from that of the control was observed only in the quaking mutant brain, in which monosialoganglioside GM1 was significantly reduced and GM4 was completely absent. The structures of the gangliosides were determined by negative ion fast atom bombardment mass spectrometry, and the GM3 and GM4 gangliosides in the quaking brain were found to be altered in regard to their long-chain base and fatty acid compositions when compared to the normal C57BL/6 brain.
