Соотношение проформ и активных форм ммп-2, -7 в ткани опухоли и легких с метастазами в динамике развития аденокарциномы легких Льюис у мышей

Соотношение проформ и активных форм ммп-2, -7 в ткани опухоли и легких с метастазами в динамике развития аденокарциномы легких Льюис у мышей

Abstract

The balance between latent and active forms of matrix metalloprotease-2, -7 (MMP-2, -7) in tumor tissue and lungs with metastases in mice with Lewis lung adenocarcinoma (LLA) has been investigated. The tumor growth (20th day as compare to 15th day) has been defined by the increased total activity of MMP-2, -7 (active + latent forms of MMP-2, -7) in tumor tissue at the expense of proMMP-2, -7 prevalence. The positive correlation between tumor weight and proMMP-2, -7 content in tumor tissue of LLA mice has been revealed. The proMMP-2, -7 prevailed in lung tissue of intact mice. Metastases growth in lungs was followed by the increased total activity of MMP-2, -7 at fixed times (7th, 15th and 20th day after tumor transplantation) at the expense of increase in active MMP-2, -7 and decrease in latent MMP-2, -7 form. The positive correlation between the total activity of MMP-2, -7 and active MMP-2, -7 in lung tissue of mice with LLA has been revealed. It has been found that the balance between proMMP-2, -7 and active MMP-2, -7 in tumor tissue differs from the balance between very same measures in tissue of lungs with metastases. These data show different role of latent and active forms of MMP-2, -7 in tumor cells and metastases.

с метастазами при аденокарциноме легких Льюис (АЛЛ). Развитие опухоли (на 20-е сут. по сравнению с 15-ми сут.) характеризовалось увеличением общей активности ММП-2, -7 (активная форма + проММП-2, -7) в ткани опухоли за счет преобладания проММП-2, -7. Выявлена положительная корреляционная связь между весом опухоли и содержанием проММП-2, -7 в ткани опухоли мышей с АЛЛ. В ткани легких интактных животных преобладала проММП-2, -7. Развитие метастазов в легких сопровождалось увеличением общей активности ММП-2, -7 на всех исследованных сроках (7-е, 15-е и 20-е сут. после перевивки опухоли) за счет увеличения активной формы и снижения проММП-2, -7. Выявлена положительная корреляционная связь между общей активностью ММП-2, -7 и активной формой ММП-2, -7 в ткани легких мышей с АЛЛ. Обнаружено, что соотношение проформ и активных форм ММП-2, -7 в ткани опухоли отличается от соотношения этих показателей в ткани легких с метастазами, что указывает на различную роль проформ и активных форм ММП-2, -7 в клетках опухоли и метастазах
