Изучение генетического дисбаланса в клетках узлов миомы матки важно для понимания патогенеза заболевания. Цель: Изучить спектр изменений в структуре хромосомы 1 и частоты их встречаемости в некультивированных клетках узлов миомы матки с учетом наличия/отсутствия мутаций в гене MED12 . Материал и методы. Исследование проведено на образцах 4 миоматозных узлов крупного размера (d = 7-20 см). Спектр изменений в структуре хромосомы 1 определен методом aCGH. Частота встречаемости клеток с изменениями хромосомы 1 определена методом FISH с использованием ДНК-зондов, специфичных к локусам 1pTEL, 1p36, 1q25. Наличие мутаций в экзоне 2 гена MED12 и в прилегающих интронных последовательностях проанализировано методом секвенирования по Сэнджеру. Результаты. Генетический дисбаланс хромосомы 1 выявлен во всех изученных образцах миом. Мутаций в гене MED12 не выявлено ни в одном из образцов. Спектр выявленных аномалий хромосомы 1, включающий делеции и дупликации, сходен между разными опухолями, однако представленность субпопуляций клеток с различными аномалиями характеризуется вариабельностью. Во всех миомах клетки с аномалиями были представлены минорными, а клетки с двумя копиями хромосомы 1 - мажорными субпопуляциями. Выводы. Генетический дисбаланс хромосомы 1 специфичен для клеток миом матки. Выявленные аномалии, вероятно, не являются триггерами возникновения миомы, однако могут быть значимы для опухолевого роста.</p></abstract><trans-abstract xml:lang="en"><p>Introduction: The study of genetic imbalance in uterine leiomyoma cells is important for understanding of the disease pathogenesis. Purpose: To study the spectrum of chromosome 1 aberrations and their frequency in non-cultured uterine leiomyoma cells depending on the presence or absence of MED12 mutations. Materials and Methods: The study was performed on 4 samples from large uterine leiomyomas (d = 7-20 cm). The spectrum of chromosome 1 aberrations was revealed by aCGH. The frequency of cells containing chromosome 1 aberrations was determined by FISH using DNA probes for 1pTEL, 1p36, 1q25. The detection of MED12 mutations in exon 2 and adjacent introns was performed by PCR-direct sequencing. Results: The chromosome 1 genetic imbalance was detected in all studied samples. No MED12 mutations were revealed in either sample. The spectrum of chromosome 1 aberrations included both deletions and duplications and was similar in all tumors. However, the cell subpopulations with different aberrations were present to different degrees among samples. In all uterine leiomyomas, cells with chromosome 1 aberrations were present by minor subpopulations, whereas cells with two copies of chromosome 1 represented major subpopulations. Conclusions: Chromosome 1 genetic imbalance is typical for uterine leiomyoma. The detected aberrations, most likely, are not leiomyoma triggers, but may have significance for tumor growth.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миома матки</kwd><kwd>генетический дисбаланс по хромосоме 1</kwd><kwd>субпопуляции клеток</kwd><kwd>aCGH</kwd><kwd>FISH</kwd><kwd>мутации гена MED12</kwd><kwd>uterine leiomyoma</kwd><kwd>chromosome 1 genetic imbalance</kwd><kwd>cell subpopulations</kwd><kwd>aCGH</kwd><kwd>FISH</kwd><kwd>MED12 mutations</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">Commandeur AE, Styer AK, Teixeira JM.
