Ген EGR1 кодирует белок, который функционирует как регулятор транскрипции генов, задействованных в процессах митогенеза и дифференцировки клеток. Для исследования была взята рандомизированная выборка рыб (n = 15) возраста 6, 12 и 18 месяцев. Для оценки уровня экспрессии гена EGR1, расположенного на 14-й хромосоме, был взят ген, кодирующий глюкозо-6-фосфатдегидрогеназу (G6PD). Анализ уровня относительной экспрессии гена EGR1 в тканях прямой кишки выявил значительные различия в разный возрастной период радужной форели. Экспрессия в тканях прямой кишки в возрасте 6 мес. была максимальной, а в возрасте 12 мес. — минимальной, но достоверных различий не было установлено (р = 0,2648). В результате анализа изменений уровня относительной экспрессии гена EGR1 в тканях сердца радужной форели в разном возрасте установлено, у группы рыб возраста 6 мес. уровень экспрессии был максимальным в сравнении с группами 12 мес. и 18 мес. (р &lt; 0,01). Полученные результаты свидетельствуют о важной роли белка EGR1 как транскрипционного фактора в росте и развитии рыбы. Накопление массы происходит наиболее интенсивно именно в раннем возрасте (до 6 мес.), и этот процесс, вероятно, обусловлен повышенной транскрипцией гена EGR1. Наличие отрицательных корреляций между экспрессией изучаемого гена в сердце и рядом размерновесовых показателей указывает на роль других транскрипционных факторов, влияющих на формирование таких показателей.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this study was to study the dynamics of the comparative level of expression of the EGR1 gene in the tissues of rainbow trout at different ages. The EGR1 gene encodes a transcription factor that influences the transcription of a large number of genes from both the 5-bar and 3-bar ends of genes. A random sample of fish aged 6, 12 and 18 months was taken for the study. To assess the expression level of the EGR1 gene, located on 14 chromosomes, a housekeeping gene was taken: G6PD. A comparative analysis of the expression level of the EGR1 gene in rectal tissues revealed a significant change in different age periods of rainbow trout. Expression in the tissues of the rectum at the age of 6 months was maximal, and at the age of 12 months it was minimal, but no significant differences were found (p = 0.2648). As a result of the analysis of changes in the level of relative expression of the EGR1 gene in the heart tissues of rainbow trout at different ages, it was found that in the group of fish aged 6 months, the expression level was maximum at the stage of 12 and 18 months (р &lt; 0.01). As a result of the study, a correlation between the size and weight parameters of rainbow trout and the level of gene expression in different eras and in different countries was established. Expression dynamics at different ages in rainbow trout were also determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радужная форель</kwd><kwd>ген</kwd><kwd>EGR1</kwd><kwd>экспрессия генов</kwd><kwd>РНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rainbow trout</kwd><kwd>gene</kwd><kwd>EGR1</kwd><kwd>gene expression</kwd><kwd>RNA</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа проведена в рамках выполнения научных исследований  Министерства науки и высшего образования РФ по теме ГЗ № 124020200114-7.</funding-statement><funding-statement xml:lang="en">The study was funded by scientific research of the Ministry of Science and Higher Education of the Russian Federation on the topic No 124020200114-7.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Макоедов А.Н., Матишов Г.Г., Пономарева Е.Н.
