Therefore we conducted analysis of the epigenetic phenomenon, which regulates expression of the genes, involved in the placenta formation processes. It was suggested, that abnormal methylation levels of human endogenous retroviruses ERVWE1 и ERVFRDE1 genes in chorionic tissue of the placenta fetal part can be associated with pathological course and adverse outcome of the pregnancy.</abstract><trans-abstract xml:lang="ru">Поиск причин, лежащих в основе патологических процессов эмбрионального развития человека, занимает лидирующую позицию среди исследований в области репродукции человека. Поэтому нами был проведен анализ эпигенетических феноменов, регулирующих экспрессию генов, которые вовлечены в процессы формирования плаценты. Было установлено, что нарушенный уровень метилирования генов эндогенных вирусов человека ERVWE1 и ERVFRDE1 в хорионической ткани плодной части плаценты может быть ассоциирован с патологическим течением и неблагоприятным исходом беременности.</trans-abstract><kwd-group xml:lang="en"><kwd>ERVWE1</kwd><kwd>ERVFRDE1</kwd><kwd>noncarrying of pregnancy</kwd><kwd>methylation</kwd><kwd>genes of human endogenous retroviruses (HERV)</kwd><kwd>ERVWE1</kwd><kwd>ERVFRDE1</kwd><kwd>placenta</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>невынашивание беременности</kwd><kwd>метилирование</kwd><kwd>гены эндогенных вирусов человека</kwd><kwd>плацента</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Белоусов Л.В.
