Modern молекулярно-trouble-shooting tests quickly move ahead in a direction of increase of their sensitivity and specificity. Now for identification virus ДНК various techniques of hybridization ДНК and molecular cloning are used. The most sensitive method now recognizes полимеразная chain reaction with типоспецифическими and species-specific праймерами, allowing to reveal virus sequences in геноме cells{cages} of tumours шейки a uterus in 95-100 % of cases [5,14,18,22]. Now it is identified more than 100 types ВПЧ, are in detail described more than 70 types, the fact is fixed, that certain types ВПЧ can infect strictly certain kind эпителия and to cause characteristic changes. Revealing of multi-variant approach of genotypes ВПЧ and identification of the data specific accumulation about malignant transformation генитальных кондилом have allowed to consider{examine} папилломавирус as possible{probable} этиологический the factor of development РШМ [13,15,20,23].

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.
