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.

Depth инвазии tumours, defeat of lymphatic vessels and units, параметральная and влагалищная инфильтрация do not depend from молекулярно-genetic a determinant of infection ВПЧ [14]. Кing (1989) has not found out communication{connection} between type ВПЧ revealed in a tumour and frequency of metastasises in регионарные лимфоузлы, Girardi (1992) observed more often defeat параметриев and лимфоузлов in cases, positive on ВПЧ type 16. Results of researches Sebbelov (1991), Kentner (1993), Ikenberg (1994) have not shown association between молекулярно-genetic determinants of infection ВПЧ and the forecast, in works Walker (1989) and Burnett (1992) is informed on much worse forecast in cases, positive on ВПЧ type 18 [цит. On 14]. However the majority of researches includes no more than 100 cases, thus definition of presence of virus sequences was made by a method of блот-hybridization on Саузерну, allowing to reveal fragments генома ВПЧ no more than in 75 % of cases РШМ [14].
