Here we use a comparative genomics approach and conservation analysis to study evolutionary specificity of nine human tumor-specific sequences, described previously. Three sequences had originated in the primate lineage. The other three had mammalian orthologs, but conservation analysis has shown that these sequences evolved neutrally. Three sequences were conservative. These data confirm previously formulated hypothesis that evolutionarily new genes are expressed in tumors.</p></abstract><trans-abstract xml:lang="ru"><p>В предыдущих работах мы определили новый класс последовательностей человека, экспрессирующихся преимущественно в опухолях. Здесь мы представляем результаты сравнительно-геномного анализа и анализа консервативности для девяти ранее описанных опухолеспецифических последовательностей. Tри последовательности специфичны для приматов. Для трех последовательностей, имеющих ортологи в геномах млекопитающих, анализ частот нуклеотидных замен и поиск консервативных элементов показал, что они эволюционируют нейтрально. Oставшиеся три последовательности являются консервативными. Эти результаты подтверждают ранее сформулированную нами гипотезу о том, что в опухолях экспрессируются эволюционно новые последовательности.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ЭВОЛЮЦИОННО-НОВЫЕ ГЕНЫ</kwd><kwd>ОПУХОЛЕСПЕЦИФИЧЕСКИЕ ТРАНСКРИПТЫ</kwd><kwd>ОПУХОЛИ И ЭВОЛЮЦИЯ</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Eвтушенко В.
