Biosynthesis of the so-called "a" and "asialo" pathway glycosphingolipids is differentially regulated in murine myelogenous leukemia NFS60 cells.


Regulation of "a" and "asialo" series ganglioside biosynthesis was analyzed. COS-1 cells expressing only GD1a showed high synthetic activities of GM3, GM2, GM1a, and GD1a, but little activity for GA2 synthesis. However, IL-3-dependent murine NFS60-I7, which has GM1b and GD1 alpha, exhibited high synthetic activities of GM2, GM1a, and GD1a, but GM3 synthase… (More)
