title: [Changes in the contents of phosphoinositides in formed elements of blood and endometrial tissue in patients with hyperplastic processes and cancer of the endometrium].
abstract: The levels of phosphoinositides were measured in blood macrophages, platelets, lymphocytes, granulocytes, neutrophils, and red cells, as well as in endometrial tissue of 175 patients with glandular hyperplasia of the endometrium, atypical hyperplasia, endometrial polyps and cancer. A reliable reduction of the content of phosphatidyl inositides and phosphatidyl inositide-S-phosphates was observed in all formed elements of the blood, the most marked decrease being observed in endometrial cancer. On the contrary, the content of phosphatidyl inositide-4-phosphates and phosphatidyl inositide-4.5-diphosphates in the macrophages, lymphocytes, and granulocytes was reliably increased in the patients as against healthy women. The process of phosphatidylinositide phosphorylation run an absolutely different course in pathologically altered endometrial tissue than in comparison with that in blood cells. A new phosphatidyl inositide-signal mechanism was revealed, which is unrelated to inositol-1.4.5-triphosphate, as a result of which the potentiality of appearance of new secondary messengers actively participating in cell growth increases.
