SV-40 transformation: effect on GM2 ganglioside in cultured cell lines. In previous work, we observed the presence of substantially elevated levels of GM2 after Simian Virus 40 (SV-40) transformation of human fetal brain cells. This elevated level of GM2 contrasted with the reports of many other investigators who had often observed decreased levels of GM2 and a simplification of ganglioside pattern in various non-neural rodent cell lines. In order to determine if the increase in GM2 in the transformed human brain cells would also be found in transformed rodent brain cells, we analyzed ganglioside changes after transformation in mouse brain cell lines and observed the increase in GM3 and low levels or lack of GM2 usually noted in rodent SV-40 transformed cell lines. In addition, we analyzed changes after SV-40 transformation in three human fibroblast lines and found that all three lines contained substantially elevated levels of GM2 after SV-40 transformation. As a result of this study, our earlier work on SV-40 transformed human brain cells, and occasional other reports of high levels of GM2 in human SV-40 transformed cell lines, elevated levels of GM2 may be considered a marker for SV-40 transformed human cells of both fibroblastic and neural origin.
