Несмотря на то что Kaiso интенсивно экспрессируется в центральной нервной системе, его участие в регуляции поведения изучено слабо. Так, было показано только участие Kaiso в регуляции поведенческой реакции на эмоциональный стресс в тестах «открытое поле» и «принудительное плавание». Целью данного исследования является выяснение роли, которую играет Kaiso в регуляции суточной активности, а также поведенческого ответа на стимуляцию неспецифического иммунитета. Опыты проводились на половозрелых самцах мышей с нокаутом гена Zbtb33 (KO) и животных линии C57BL/6 (дикий тип, WT). Все животные были в возрасте 11 недель, имели SPF ( specific pathogen free) статус на протяжении всего эксперимента. Животных каждого генотипа разделяли на три выравненные по весу группы по восемь животных в каждой. Вначале измеряли суточную динамику двигательной активности, сна, потребления пищи и воды интактных животных с помощью программно-аппаратного комплекса PhenoMaster. Затем животным каждой группы внутрибрюшинно вводили физиологический раствор (контроль), 0.1 или 1.0 мг/кг бактериального липополисахарида (ЛПС), растворенного в физиологическом растворе, и вновь измеряли суточную активность, потребление пищи и воды. Интактные мыши KO и WT не различались по среднесуточным двигательной активности и продолжительности сна. Однако интактные мыши KO были менее активны в темное время суток, а также потребляли меньше пищи и воды по сравнению с интактными животными WT. Обе дозы ЛПС подавляли двигательную активность, увеличивали продолжительность сна и вызывали анорексию у мышей обоих генотипов. Одна ко эффект низкой дозы ЛПС (0.1 мг/кг) на потребление пищи и воды был более выражен у мышей KO, чем у животных WT. Полученные результаты проливают свет на биологическую значимость гена Kaiso и служат обоснованием необходимости нормального функционирования этого гена в природных популяциях.</p></abstract><trans-abstract xml:lang="en"><p>The Zbtb33 gene encodes the bimodal transcriptional repressor Kaiso, which causes epigenetic repression of genes by binding to methylated mCpG islets in the promoters of the genes. Despite the fact that Kaiso is intensively expressed in the central nervous system, its participation in the regulation of behavior is still poorly understood. Only the participation of Kaiso in the regulation of the behavioral response to emotional stress in the open field and forced swimming tests has been shown. The aim of this study is to elucidate the role that Kaiso plays in regulating daily activity, as well as the behavioral response to stimulation of nonspecific immunity. Experiments were performed on adult male mice with Zbtb33 gene knockout (KO) and animals of the C57BL/6 line (wild type, WT). All animals were 11 weeks old, weighed 26 ± 1 g and had SPF (specific pathogen free) status throughout the experiment. The animals of each genotype were divided into three weighted groups of 8 animals each. Initially, the daily dynamics of motor activity, sleep, food and water intake of intact animals was measured using the PhenoMaster software-hardware complex. The animals of each group were then injected with saline (control), 0.1 or 1.0 mg/kg of bacterial lipopolysaccharide (LPS) dissolved in saline, and again measured for their daily activity, food and water intake. Intact KO and WT mice did not differ in the average daily motor activity and sleep duration. However, intact KO mice were less active in the dark time, and also consumed less food and water as compared to intact WT animals. LPS at both doses suppressed motor activity, prolonged sleep duration and caused anorexia in mice of both genotypes. However, the effect of low dose of LPS (0.1 mg/kg) on the food and water intake was more pronounced in KO mice than in WT animals. The results shed light on the biological significance of the Kaiso gene and serve as a justification for the necessity of the normal functioning of this gene in natural populations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ген Kaiso</kwd><kwd>нокаутные мыши</kwd><kwd>PhenoMaster</kwd><kwd>домашняя клетка</kwd><kwd>LPS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Kaiso gene</kwd><kwd>knockout mice</kwd><kwd>PhenoMaster</kwd><kwd>home cage</kwd><kwd>LPS</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">Bali P., Im H.I., Kenny P.J.
