title: [Effect of insulin on the composition of chromatin phospholipid in rat liver cells].
abstract: In vivo the action of insulin on rat liver chromatin phospholipid composition was investigated. It was shown that the hormone led to reliable increase (nearly 20%) of total phospholipid content. The same phenomenon was shown also in the fraction of active chromatin while the phospholipids content of non-active chromatin didn't changed. It was also shown that the content of three from six phospholipid fractions altered under the insulin action. The content of sphingomyelin and phosphatidilethanolamine increased and the quantity of phosphatidylinositol decreased under the hormone action. The decrease of monophosphoinositides content was accompanied by the reliable increase of triphosphoinositides amount. It was suggested that the fractions of chromatin polyphosphoinositides were redistributed under the action of insulin.
