RNA samples isolated from rat liver and kidneys were used as research materials.</p><p>The multiplicity of expression of the MT3 gene in the kidneys increased at the lowest dose of CdCl2 , which was used in this experiment (0.029 mg / kg); with increasing dosage, the expression level decreased, but not lower than the control values. Analysis of the expression of the same gene in the liver showed a tendency towards a decrease in the content of transcripts with increasing dose. The frequency of expression of the MT2A gene at higher doses of CdCl2 increased both in the liver and in the kidneys.</p><p>In the present work, statistically significant dose-dependent changes in the expression multiplicity of metallothionein genes were detected 24 hours after CdCl2 administration. The revealed differences in the level of transcriptional activity of metallothionein genes require further investigation, since there are probably differences in the level of gene expression at earlier and later periods of toxicant action.</p></abstract><trans-abstract xml:lang="ru"><p>Цель работы - изучить экспрессию генов металлотионеина в печени и почках крыс при остром отравлении кадмием. Моделирование отравления хлоридом кадмия проводили на белых беспородных крысах женского пола, разделенных на 4 группы в зависимости от дозы введенного токсиканта. В качестве материалов исследования использовали образцы РНК, выделенные из печени и почек крыс. Кратность экспрессии гена МТ3 в почках повышалась при наименьшей дозе CdCl2, которая была использована в данном эксперименте (0,029 мг/кг), с увеличением дозировки уровень экспрессии снижался, но не ниже показателей контроля. Анализ экспрессии этого же гена в печени показал наличие тенденции к снижению содержания транскриптов при увеличении дозы. Кратность экспрессии гена МТ2A при более высоких дозах CdCl2 повышалась как в печени, так и в почках. В представленной работе были выявлены статистически значимые дозозависимые изменения кратности экспрессии генов металлотионеина через 24 часа после введения CdCl 2. Обнаруженные нами различия в уровне транскрипционной активности генов металлотионеина требуют дальнейшего исследования, так как вероятно, существуют различия в уровне экспрессии генов на более ранних и более поздних сроках действия токсиканта.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cadmium</kwd><kwd>metallothioneins</kwd><kwd>gene expression</kwd><kwd>oxidative stress</kwd><kwd>dose-dependent change in expression</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кадмий</kwd><kwd>металлотионеины</kwd><kwd>экспрессия генов</kwd><kwd>окислительный стресс</kwd><kwd>дозозависимое изменение экспрессии</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Sukharenko E.V., Maximov V.I.
