Определение специфичной панели микроРНК, отличающей пациентов с БИК и АКТГ-эктопированным синдромом (АКТГ-ЭС), смогло бы значительно упростить диагностику.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Выявить циркулирующие микроРНК, отличающиеся у пациентов с БИК и АКТГ-ЭС в плазме крови, оттекающей от гипофиза.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Выполнено одноцентровое, одномоментное, выборочное исследование случай-контроль. Включено 24 пациента с АКТГ-зависимым ЭГ, которым требовалось проведение селективного забора крови из нижних каменистых синусов (НКС). Из них 12 пациентов с БИК (м=2, ж=10), возрастная медиана 46,5 лет [33,8;53,5] и 12 пациентов с АКТГ-ЭС (м=4, ж=8), возрастная медиана 54 года [38,75;60,75].  Образцы плазмы крови из НКС были получены до введения стимуляционного агента, центрифугированы и заморожены при температуре -80С. Выделение микроРНК из плазмы крови проводили с помощью miRNeasy Serum/Plasma Kit («Qiagen», Германия) согласно инструкции компании-производителя на автоматической станции QIAcube («Qiagen», Германия). Концентрацию суммарной РНК в водном растворе оценивали на спектрофотометре NanoVue Plus («GE Healthcare», Великобритания). Библиотеки были подготовлены с помощью QIAseq miRNA Library Kit согласно стандартным протоколам производителя. Экспрессию микроРНК исследовали с помощью секвенирования на Illumina NextSeq 500 (Illumina NextSeq 500, США).</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Обнаружены 108 дифференциально экспрессирующихся микроРНК  (p &lt;0,05) после поправки на множественность сравнений. МикроРНК разделены на три группы – группа 1 с числом прочтений более 10 в обеих группах сравнения, группа 2 с числом прочтений менее 10 в одной из групп, группа 3 с числом прочтений менее 10 в обеих группах. Для верификации методом количественной ПЦР с обратной транскрипцией (RT-qPCR), планируется использовать следующие микроРНК: miR-383-3p, miR-4290 и miR-6717-5p, экспрессия которых была повышена у пациентов с БИК по сравнению с пациентами из группы АКТГ-ЭС в 46,36 раз (p=0,01), в 6,84 раз (p=0,036) и в 4,49 раз (p=0,031), соответственно,  miR-1203, miR-1229-3p, miR-639, экспрессия которых была снижена у пациентов с БИК в 36,74 раз (p=0,013), в 78,3 раз (p=0,003), в 73,22 раза (p=0,002), соответственно, а также miR-302c-3p,  экспрессия которой была повышена у пациентов с БИК в 92,69 раз (p=0,001).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. В ходе исследования был значительно расширен список микроРНК-кандидатов для диагностики АКТГ-зависимых форм ЭГ. Необходима валидизация полученных микроРНК в периферической крови на расширенной выборке пациентов методом RT-qPCR.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: For the last decades microRNAs (miR) have proven themselves as novel biomarkers for various types of diseases. Identification of specific circulating microRNA panel that differ patient with Cushing’s disease (CD) and ectopic ACTH syndrome (EAS) could improve the diagnostic procedure.</p></sec><sec><title>AIM</title><p>AIM: to evaluate the differences in miR levels in plasma samples drained from inferior petrosal sinuses in patients with CD and EAS.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: single-center, case-control study: we enrolled 24 patients with ACTH-dependent Cushing’s syndrome (CS) requiring bilateral inferior petrosal sinus sampling (BIPSS).  Among them 12 subjects were confirmed as CD (males=2, females=10; median age 46,5 [IR 33,8;53,5]) and 12 as EAS (males=4, females=8, median age 54 [IR 38,75;60,75]). BIPSS was performed through a percutaneous bilateral approach. Once catheters were properly placed, blood samples were withdrawn simultaneously from each petrosal sinus and a peripheral vein. Plasma samples from both sinuses were centrifuged and then stored at -80 C. MiRNA isolation from plasma was carried out by an miRneasy Plasma/Serum Kit (Qiagen, Germany) on the automatic QIAcube station according to the manufacturer protocol. To prevent degradation, we added 1 unit of RiboLock Rnase Inhibitor (Thermo Fisher Scientific, USA) per 1 μL of RNA solution. The concentration of total RNA in the aqueous solution was evaluated on a NanoVue Plus spectrophotometer (GE Healthcare, USA). The libraries were prepared by the QIAseq miRNA Library Kit following the manufacturer standard protocols. MiR expression was then analyzed by sequencing on Illumina NextSeq 500 (Illumina, USA).</p></sec><sec><title>RESULTS</title><p>RESULTS: 108 miRNAs were differently expressed (p &lt;0,05) in inferior petrosal sinus samples of patients with CD vs EAS. We divided these miRNAs into 3 groups based on the significance of the results. The first group consisted of samples with the highest levels of detected miR in both groups. Four miRNAs were included: miR-1203 was downregulated in CD vs EAS — 36.74 (p=0,013), and three other were upregulated in CD vs EAS: miR-383-3p 46.36 (p=0,01), miR-4290 6.84 (p=0,036), miR-6717-5p 4.49 (p=0,031). This miRs will be validated in larger cohorts using RT-qPCR.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: Plasma miR levels differ in inferior petrosal samples taken from patients with CD vs EAS. These miRs need to be validated by different methods and in peripheral plasma samples in order to be used as potentially non-invasive biomarkers to differentiate ACTH-dependent CS.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Болезнь Иценко-Кушинга</kwd><kwd>АКТГ-эктопированный синдром</kwd><kwd>микроРНК</kwd><kwd>NGS</kwd><kwd>аденома
