медуллярный рак щитовидной железы

Evolution of surgical approaches from radical мастэктомии Холстеда up to органосохраняющих operations, has allowed to look more widely at a problem of surgical treatment and to pay attention to operative interventions which were applied, basically, at good-quality diseases dairy железы or as preventive procedure. Thus the basic purpose, certainly, was improvement of quality of a life of patients by a cancer dairy железы by optimization of results of reconstructive - plastic interventions. Подробнее...

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.
