Starting at E12.5, Sip1 transcripts are present in a regionalized fashion and persist throughout development. Sip1 is expressed in the cortical plate, ventricular zone of the basal ganglia, thalamus, pons and midbrain, specific nuclei of the brain stem and in the dorsal part of the spinal cord. In the developing cerebral cortex, Sip1 expression shows regional specificity. In the brain of the adult mice, SIP1 expression is detected mostly in the hippocampus, dentate gyrus and white matter of the neocortex.</p> <p>We investigated the expression of the Sip1 gene in the brains of newborn reeler mutants. At this stage in the wild type piriform cortex Sip1 expression is found in the most outer part. In the piriform cortex of reeler mutants Sip1 expressing cells were not located in the superficial part but diffused.</p> <p>Using a Cre/loxP-based approach, we studied the effect of conditional inactivation of Sip1 gene. The results provide new evidence for the important role of Sip1 in hippocampal neurogenesis.</p></abstract><trans-abstract xml:lang="ru"><p>Недавно описанный ген Sip1 относится к транскрипционным факторам семейства ZFHX1 позвоночных. Используя методы in situ гибридизации и иммуноокрашивания, мы изучили экcпрессию гена Sip1 в эмбриогенезе. Начиная с 12-го дня эмбрионального развития мыши, транскрипты Sip1 присутствуют в ряде структур центральной нервной системы: кортикальная пластинка головного мозга, вентрикулярная зона базального ганглия, таламус, варолиев мост, средний мозг, специфические ядра ствола мозга и дорзальная часть спинного мозга. Во взрослой ткани мозга экспрессия Sip1 обнаруживается в гиппокампе, зубчатой извилине и белом веществе. В коре головного мозга экcпрессия гена Sip1 обнаруживает региональную специфичность. Мыши с инактивированным геном Sip1 в неокортексе характеризуются отсутствием медиальной части коры. Посредством анализа экспрессии генов и морфологии мозга установлено, что при отсутствии Sip1 зоны гиппокампа нормально специфицируются в ходе развития. Анализ пролиферации клеток гиппокампа мутантов Sip1 не выявил изменений в активности. Посредством окрашивания по протоколу TUNEL был выявлен высокий уровень клеточной смерти в ткани гиппокампа у мышей, мутированных по гену Sip1.</p> <p>Данные результаты доказывают важность выполняемой геном Sip1 функции для нормального развития гиппокампа и зубчатой извилины.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Sip1</kwd><kwd>embryogenesis</kwd><kwd>cortical plate</kwd><kwd>brain</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Sip1</kwd><kwd>эмбриогенез</kwd><kwd>кортикальная пластинка</kwd><kwd>головной мозг</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Поляков А.С., Британова О.В., Усман Н.Ю. и др.
