[Phospholipid composition of nuclear membranes and cell nuclei of rat liver and hepatoma 27].
Phospholipid composition of nuclei and nuclear membranes from rat liver and hepatoma-27 were investigated. Hepatoma nuclei and nuclear membranes were found to contain cardiolipin which was absent in the same fractions of rat liver. In the nuclei and nuclear membranes of hepatoma the content of sphingomyelin was higher and that of lecithin is lower than in the corresponding subcellular fractions of  rat liver. The content of acid phospholipids was much higher in hepatoma nuclear membranes than those of the normal liver. The data obtained show that the general trend of lipid dedifferentiation which earlier was demonstrated for various membranes of different tumor cells is observed also in the case of nuclear membranes.
