摘要: The composition of gangliosides was examined in a normal rat embryo fibroblast cell line (REF52) and two viral transformants: polyoma transformant (REF52-PyMLV) simian 40 (REF52-SV40). distribution the lines determined using gas-liquid chromatography high-performance thin-layer chromatography. N-acetylneuraminic acid predominant sialic species detected three lines. total ganglioside concentration (microgram/100 mg dry weight cells) normal, PyMLV, SV40 144.7 +/- 10.4, 153.8 9.2, 86.1 6.8, respectively. Gangliosides GM3, GM2, GM1, GD1a were major transformed these gangliosides, however, differed markedly between also themselves. cells from growth rate, morphology, social behavior. with highest GM3 content (PyMLV) formed islands, whereas lines, which had lower levels, grew as monolayers. findings suggest that PyMLV transformation can have multiple different effects on cellular
