лечение стволовыми клетками онкологии

The direction of action of fiber Е6 (супрессорное or трансактивирующее) is defined{determined} by character, position and number of sites of linkage транскрипционных factors in promotors. The promotor р97 (ВПЧ type 16) can play a role in maintenance of a latent condition of a virus infection. With онкобелком Е6 ВПЧ types 16 and 18 7 cellular fibers cooperate at least, now from them 3 cellular fibers are identified: р53, Е6-АР, Е6-ВР. The gene р53 is associated both with the control of cellular growth, and with неопластической transformation; делеции or mutations in some cases transform р53 in active онкоген. Not all malignant tumours have mutations р53, the alternative mechanism инактивации р53 however is proved by linkage with онкобелком Е6 ВПЧ types 16 and 18, that results in loss of the control for пролиферацией cells{cages}. Cellular fiber Е6-АР (Е6 associated protein) in a complex with онкобелком Е6 participates in degradation р53, and also, probably, shortens the period полужизни and reduces a level р53 in ВПЧ-иммортализованных cells{cages}. Fiber Е6-ВР (E6-binding protein) cooperates with gene Е6 ВПЧ of types 16 and 18, that in result results in inhibition of process of a differentiation of cells{cages} and, probably, creates conditions for репликации virus ДНК.

There are messages on detection virus ДНК in cells{cages} РШМ both in integrated, and in эписомальной forms. Essential distinctions in character of integration ВПЧ of types 16 and 18 come to light. On the basis of the data on forms of integration virus ДНК assumptions of the possible{probable} importance of both forms персистенции ДНК ВПЧ types 16 and 18 are stated, and integration is not a determining part in the mechanism of an induction туморогенеза [23].
