[Shifts in phospholipid composition of the nuclear matrix in rat liver cells exposed to insulin]. / Sdvigi v sostave fosfolipidov iadernogo matriksa kletok pecheni krys pri vozdeistvii insulina.

It was shown that the total content of phospholipids of rat liver nuclear matrix increased after in vivo action of insulin (2 units per 100 g of animal weight). At the same time the sphyngomyelin content was increased and the content of phosphatydilcholine and phoshpatydilinositol was decreased significantly under the hormone action. The decreasing of monophosphoinositides amount was accompanied by the increasing of triphosphoinositides content which indicates the redistribution among the phosphoinositides fractions under the hormone action and may be the result of insulin initiation of phosphoinositide pathway in nuclear membrances.
