[Neutral lipids of nuclear membranes and chromatin in rat liver after hydrocortisone administration]

It is shown that over 80% of nuclear neutral lipids are found in the nuclear membrane preparations, whereas only 7%--in chromatin. The injection of hydrocortisone to animals significantly decreases the neutral lipids content in both fractions. These results and the data obtained previously by the authors indicate the possible participation of nuclear membrane and chromatin lipids in the process of hormonal regulation of the genetic activity.
