Lipid composition of SV40-induced transplantable hamster tumor.

The analysis of the lipid composition of the SV40-induced transplantable hamster tumor has shown that: (a) the total phospholipid content in the tumor is lower than that usually found in normal tissues and similar to that reported for other neoplasms; (b) except for a lower percentage of diphosphatidylglycerol, the phospholipid composition is comparable with that reported for normal tissues; (c) the fatty acid profiles of the various glycerophospholipid classes are characterized by high proportions of oleic acid; and (d) phosphatidylethanolamine contains proportions of alkenyl side chains which are consistent with the amounts of plasmalogenic phospholipids found in other neoplasms.
