Регуляторная the area virus генома (upstream regulatory region, URR) settles down between the end of area of late genes and the beginning of area of early genes. Open frameworks of reading ORF генома a virus are divided{shared} on early (early, Е) and late (late, L) sites. The early fragment includes genes Е1-Е7 coding synthesis of fibers, responsible{crucial} for various functions in process репликации a virus and transformation of cells{cages}. Genes Е1 and Е2 are responsible{crucial} for репликацию a virus, and also participate in regulation of a transcription virus генома. The product of gene Е1 is responsible for maintenance персистенции virus генома in эписомальной to the form. Gene Е2 codes products which can as a trance - activate, and to suppress экспрессию early genes and энхенсерных sites URR. Трансактивирующий the factor is identified in precancer changes шейки a uterus, репрессирующий the factor in vivo is not identified [16]. Gene Е4 participates during maturing virus particles, genes Е5-Е7 possess трансформирующим potential. Genes Е6 and Е7 are always defined{determined} and экспрессируются in tumours шейки a uterus and received of tumours шейки a uterus cellular lines. The biological effect трансформирующего potential of genes Е6 and Е7 will be considered below. The late fragment генома will consist of genes L1 and L2, coding structural fibers вириона [5,21].

The decision on a choice of preparations for chemotherapy of the second line should be based, first of all, on definition of sensitivity of a tumour to derivatives of platinum after chemotherapy of the first line. The interval between the termination{ending} of therapy of the first line and progressing of disease more than 6 months testifies to high sensitivity of a tumour derivatives of platinum. Such patient for treatment of relapses should be appointed a combination of derivatives of platinum and new preparations from among that are used for carrying out of the second line of chemotherapy. At separate patients with duration of remission more than 12 months probably carrying out of chemotherapy of the second line by the same combination which was used at a stage of an induction. Frequency of objective effect at use of a combination of derivatives of platinum (is $more often карбоплатина in view of his{its} smaller toxicity) and new preparations makes 30-50 % at average life expectancy of sick 12-14 months.
