Применение генотерапевтических препаратов для лечения генетических заболеваний и стимуляции процессов регенерации является длительным и подразумевает осуществление повторных инъекций, что может привести к усилению диссеминации генотерапевтических конструкций из области введения и нежелательной эктопической экспрессии закодированных в них ростовых факторов. Существующие подходы по изучению фармакокинетики лекарственного препарата для оценки диссеминации генотерапевтического препарата из очага введения неприменимы. Цель: оценить пригодность метода ПЦР в реальном времени для изучения биораспределения перспективного генотерапевтического препарата в организме мыши при курсовом применении. Методы. Самцам мышей F1 CBA×C57/Black делали инъекции исследуемой плазмиды в денервированную большеберцовую мышцу после травмы нерва, а также через 4, 9 и 13 дней в дозировке 60 и 120 мкг/мышь. Через 7, 14 и 28 дней после окончания курса инъекций образцы органов и тканей изымали, тотальную ДНК выделяли, и содержание плазмидной ДНК оценивали с помощью ПЦР в реальном времени. Результаты. Было показано, что изученная генетическая конструкция способна диссеминировать из области введения. Было установлено, что пик диссеминации для данной конструкции в органах и тканях мыши достигается через 14–28 суток после окончания курсового применения, при этом эктопической экспрессии факторов роста в них не наблюдается. Заключение. Предложенный метод является специфичным, высокочувствительным и линеен в широком диапазоне концентраций. Таким образом, он может быть рекомендован для изучения биораспределения потенциальных генотерапевтических препаратов в организме экспериментальных животных в рамках комплекса доклинических исследований.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The use of gene therapy drugs for the treatment of genetic diseases and stimulation of regeneration processes is lengthy and involves repeated injections, which may lead to increased dissemination of gene therapy constructs from the injection site and undesirable ectopic expression of growth factors encoded in them. Existing approaches to study the pharmacokinetics of a drug to assess the dissemination of a gene therapy drug from the site of administration are not applicable. Objective: to evaluate the suitability of the real-time PCR method for studying the biodistribution of a promising gene therapy drug in mice during a course of use. Methods. Male F1 CBA×C57/Black mice after nerve injury were injected with the test plasmid into the denervated tibial muscle after nerve injury, as well as after 4, 9 and 13 days at a dosage of 60 and 120 μg/mouse. After 7, 14, and 28 days, organ and tissue samples were removed, total DNA was isolated, and plasmid DNA content was assessed by real-time PCR. Results. We have shown that the studied genetic construct is able to disseminate from the injection site. We have found that the peak of dissemination for this construct in the organs and tissues of the mouse is reached 14–28 days after the end of the course application, while ectopic expression of growth factors is not observed in them. Conclusion. The proposed method is specific, highly sensitive, and linear over a wide range of concentrations. Thus, it can be recommended for studying the biodistribution of potential gene therapy drugs in the body of experimental animals as part of a preclinical studies complex.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>генная терапия</kwd><kwd>плазмида</kwd><kwd>диссеминация</kwd><kwd>ПЦР в реальном времени</kwd><kwd>мыши</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene therapy</kwd><kwd>plasmid</kwd><kwd>dissemination</kwd><kwd>RealTime PCR</kwd><kwd>mice</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финасовой поддержке МинПромТорга РФ в рамках реализации Федеральной целевой программы «Развитие фармацевтической и медицинской промышленности Российской Федерации на период до 2020 года и дальнейшую перспективу».</funding-statement><funding-statement xml:lang="en">The study was financially supported by the Ministry of Industry and Trade of the Russian Federation as part of the implementation of the Federal target program “Development of the pharmaceutical and medical industries of the Russian Federation for the period up to 2020 and beyond”.</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">Одинак М.М., Живолупов С.А.
