[Investigation of lipid-exchange lipoproteins from rat liver and hepatoma 27].
A phospholipid exchange lipoprotein from the postmicrosomal supernatant of rat hepatoma 27, which stimulated in vitro the exchange of sphingomyelin between mitochondria and microsomes, was found. Sphingomyelin is incorporated into the mitochondria under incubation of this complex with rat liver mitochondria (in which sphingomyelin is absent) an microsomes. Under the same conditions the phospholipid exchange lipoproteins of rat liver do not transfer sphingomyelin form microsomes to mitochrondria.
