Развитие онкопатологий тесно связано с различными изменениями генетического материала, возникающими в злокачественно трансформированных клетках. Принятие медицинских решений требует четкой дифференциации нормальных и патологических показателей, являющихся в том числе результатами применения количественных методов в лабораторной медицине. Исследования ДНК, выделенной из биологического материала пациента, выявление и измерения содержания последовательностей нуклеотидов, выступающих в роли биомаркеров онкопатологий, позволяют решать задачи определения генетических предпосылок развития рака, его диагностики на ранней стадии, определения стратегии лечения, его мониторинга, подтверждения излечения пациента.</p><p>Целью данного исследования является выработка основных подходов к созданию стандартных образцов (СО) ДНК для метрологического обеспечения молекулярной диагностики онкопатологий на примере СО содержания последовательности гена HER2 в составе генома человека, значение величины «число копий последовательности ДНК» которого метрологически прослеживается к естественной единице SI «один».</p><p>В ходе исследования разработана методика выполнения измерений копийности (числа копий последовательности гена на геном) гена HER2, основанная на применении метода цифровой ПЦР (цПЦР). Показана сходимость результатов измерений для разработанной авторами методики и результатов, полученных с использованием коммерческого набора, использующего метод MLPA на образцах биологического материала человека.</p><p>Охарактеризованы пять постоянных клеточных линий из ЦКП «Коллекция культур клеток позвоночных» по отношению числа копий последовательностей гена HER2 и генов CEP17 и RPPH1. Выявлена клеточная линия с повышенной копийностью гена HER2. Полученные результаты будут использованы при создании СО отношения числа копий последовательностей гена HER2 и генов RPPH1 и CEP17. Создание матричных СО ДНК на основе культур клеток человека, аттестованных с применением цПЦР, позволит передавать единицу величины числа копий последовательности ДНК калибраторам, входящим в состав медицинских изделий, обеспечивая тем самым требуемую достоверность и сопоставимость результатов измерений в лабораторной диагностике онкопатологий, а также возможность калибровки рутинных методик ДНК-диагностики и внутрилабораторного контроля качества.</p></abstract><trans-abstract xml:lang="en"><p>Cancer is the leading cause of death in the world. The development of oncopathology is closely related to various changes in the genetic material that occur in malignantly transformed cells. Medical decision-making requires a clear differentiation between normal and pathological indicators, which are, among other things, the results of application of quantitative methods in laboratory medicine. Studies of DNA isolated from a patient’s biological material, identification and measurement of the content of nucleotide sequences acting as oncopathology biomarkers allow to solve the problems of determining the genetic prerequisites for cancer, its early diagnosis, determining the treatment strategy, monitoring, and confirming the patient’s cure.</p><p>The purpose of this research is to develop the main approaches to the design of DNA reference materials (RMs) for metrological support of molecular diagnostics of oncopathology through the example of the RM for the HER2 gene sequence content in the human genome, with the value of «the number of copies of the DNA sequence» which is metrologically traceable to the natural SI unit «one».</p><p>In the course of the research, a technique for measuring the HER2 gene amplification (the number of copies of the gene sequence per genome) was developed based on the use of the digital PCR method (dPCR). Comparability of measurement results for the method developed by the authors, and the results obtained using a commercial kit by the MLPA method on samples of human biological material is shown.</p><p>Five permanent cell lines obtained from the CUC «Vertebrate Cell Culture Collection» were characterized in relation to the copy number ratios of HER2 gene sequence and CEP17 and RPPH1 genes sequences. A cell line with the HER2 gene amplification was identified. The results obtained will be used to create the RM for the copy number ratio of the HER2 gene sequences and the RPPH1 and CEP17 gene sequences. Creation of matrix DNA RMs based on human cell cultures certified using dPCR will allow transferring the unit of copy numbers of the DNA sequence to calibrators included in medical devices, thereby ensuring the required reliability and comparability of measurement results in the laboratory diagnostics of oncopathology, as well as the possibility of calibrating routine methods of DNA diagnostics and intralaboratory quality control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стандартные образцы</kwd><kwd>онкодиагностика</kwd><kwd>лабораторная медицина</kwd><kwd>последовательность нуклеотидов</kwd><kwd>число копий последовательности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reference materials</kwd><kwd>cancer diagnostics</kwd><kwd>laboratory medicine</kwd><kwd>nucleotide sequence</kwd><kwd>sequence copy number</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Клеточные культуры предоставлены ЦКП «Коллекция культур клеток позвоночных».
