В результате линейного регрессионного анализа была выявлена ассоциация полиморфных локусов rs53576, rs7632287 и rs2254298 гена OXTR, rs1042615 и rs3803107 гена AVPR1A, а также rs28632197 гена AVPR1B с вариациями уровня депрессивности. Кроме того, обнаружена ассоциация статуса метилирования генов OXT (р=0,003; OR=2,12) и AVPR1A (р=0,013; OR=3,38) с повышенной депрессивностью. Полученные результаты вносят вклад в понимание биологических основ депрессии и могут быть рассмотрены в качестве биомаркеров депрессивного поведения.</p></abstract><trans-abstract xml:lang="en"><p>The present study aimed to assess the effect of DNA methylation and genetic variants of the hypothalamic-pituitary-adrenal system with phenotypic variance in depression in 1065 mentally healthy individuals controlling for sex and ethnicity. As a result of linear regression analysis, the association of polymorphic loci rs53576, rs7632287 and rs2254298 of the OXTR gene, rs1042615 and rs3803107 of the AVPR1A gene, as well as rs28632197 of the AVPR1B gene with depression level was revealed. In addition, the association of the methylation status of the OXT (Р=0,003; OR=2,12) and AVPR1A (Р=0,013; OR=3,38) genes and an increased risk of developing depression was found. The results contribute to understanding the biological basis of depression and identifying biomarkers of depressive behavior.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>депрессия</kwd><kwd>гипоталамо-гипофизарно-надпочечниковая система</kwd><kwd>окситоцин</kwd><kwd>вазопрессин</kwd><kwd>аргинин-вазопрессин</kwd><kwd>ген-средовые взаимодействия</kwd><kwd>метилирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>depression</kwd><kwd>hypothalamic-pituitary-adrenal system</kwd><kwd>oxytocin</kwd><kwd>vasopressin</kwd><kwd>arginine-vasopressin</kwd><kwd>gene-environment interactions</kwd><kwd>methylation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Broniarczyk-Czarniak M., Szemraj J., Smigielski J., Galecki P.
