title: Inhibition of highly metastatic FBJ-LL cell migration by ganglioside GD1a highly expressed in poorly metastatic FBJ-S1 cells.
abstract: For clarification of the functions of gangliosides on tumor metastasis, examination was made of the ganglioside patterns of poorly metastatic FBJ-S1 and highly metastatic FBJ-LL cells. FBJ-S1 cells expressed GM3 and GD1a, whereas FBJ-LL cells expressed GM3 and slightly expressed GD1a. The capacity for FBJ-LL cells to migrate was ten times that of FBJ-S1 cells, but decreased by a half by pretreatment with GD1a. GD1b or GT1b had the same effect as GD1a, and synthetic sialyl compounds to a lesser extent, suggesting that gangliosides contain more than two sialyl residues to inhibit the migration of FBJ-LL cells.
