Влияние кортизола в комплексе с липопротеинами очень низкой плотности на развитие гепатомы на-1 и карциномы Эрлиха

Влияние кортизола в комплексе с липопротеинами очень низкой плотности на развитие гепатомы на-1 и карциномы Эрлиха

Abstract

Исследования проводились на клетках асцитной НА-1 гепатомы и асцитной карциномы Эрлиха. После пассажа клеток на мышах выделяли смешанную культуру клеток, содержащую опухоль-ассоциированные макрофаги. Показано, что в сокультуре комплекс ЛПОНП–кортизол значительно подавлял пролиферативную активность опухолевых клеток. Полученная константа связывания кортизола с ЛПОНП указывает на то, что в комплексообразовании принимает участие белковый компонент липопротеинов. Предполагается, что в образовании такого комплекса важную роль играют опухоль-ассоциированные макрофаги. Обнаружено, что механизм подавления роста опухолевых клеток связан с апоптозом.

Studies were conducted using ascetic HA-1 hepatomas and ascitic Ehrlich’s carcinoma cells. After passage of cells in mice, cell culture containing tumor-associated macrophages was studied. It was shown that the very low-density lipoprotein (VLDL)-cortisol complex significantly inhibited proliferative activity of tumor cells. The obtained constant of cortisol binding to VLDL indicated that the protein component of lipoproteins participated in the complex formation. Tumor-associated macrophages were suggested to play an important role in the formation of this complex. It was found that inhibition of tumor cell growth was related to apoptosis.
