Актуальность. Длинные некодирующие РНК (днРНК) при раке щитовидной железы плохо изучены; не известны днРНК, общие и специфичные для фолликулярного и классического вариантов папиллярного рака, не установлены днРНК, аберрантно экспрессированные при других основных субтипах злокачественных новообразований щитовидной железы, а также при доброкачественных новообразованиях. Цель исследования - определить днРНК, аберрантно экспрессированные при фолликулярной аденоме (ФА), фолликулярном раке (ФРЩЖ), фолликулярном и классическом вариантах папиллярного рака (ПРЩЖ), анапластическом раке (АРЩЖ) щитовидной железы. Методы. Проанализирована экспрессия днРНК по данным исследований на микрочипах (8 независимых экспериментов, доступных в GEO) и секвенирования РНК (PRJEB11591 и TCGA-THCA). Исследованы 246 образцов нормальной ткани щитовидной железы, 26 - ФА, 30 - ФРЩЖ, 181 - фолликулярного варианта ПРЩЖ, 481 - классического варианта ПРЩЖ и 49 - АРЩЖ. Для классического и фолликулярного вариантов ПРЩЖ выполнена валидация дифференциальной экспрессии in silico. Потенциальные биологические функции были оценены в результате анализа обогащения коэкспрессированных генов. Результаты. Определены днРНК, дифференциально экспрессированные при ФА, ФРЩЖ, фолликулярном и классическом вариантах ПРЩЖ и АРЩЖ. Выявлены 8 днРНК, экспрессия которых изменена во всех субтипах новообразований щитовидной железы, 22 - общих для ПРЩЖ, 32 - специфичных для классического варианта ПРЩЖ, 1 - специфичная для фолликулярного варианта ПРЩЖ, и 177 - специфичных для АРЩЖ. Статистически значимо дифференциально экспрессированных днРНК в ФРЩ по сравнению с ФА не выявлено. Ранее известные онкогенные и супрессорные днРНК NR2F1-AS1, LINC00511, SLC26A4-AS1, CRNDE, RMST впервые обнаружены в новообразованиях щитовидной железы. Выявленные днРНК предположительно вовлечены в клеточную адгезию, организацию экстрацеллюлярного матрикса, образование эндодермы, регуляцию клеточного цикла и митоза, полярности клеток, сигнальные пути VEGF и WNT. Выводы. Установлены общие и специфичные паттерны экспрессии днРНК в доброкачественных и злокачественных новообразованиях щитовидной железы. Background. Long non-coding RNA (lncRNA) in thyroid cancer are poorly investigated; no lncRNAs common and specific for the follicular and classical variants of papillary cancer, as well as no lncRNAs aberrantly expressed in benign nodules or other subtypes of thyroid cancer are established. The objective of the study is to determine long noncoding RNAs aberrantly expressed in follicular adenoma (FA), follicular carcinoma (FTC), follicular and classical variants of papillary carcinoma (PTC), anaplastic carcinoma (ATC). Methods. lncRNA expression was analyzed in dataset of Microarray (8 independent experiments available in GEO) and RNA-seq studies (PRJEB11591 and TCGA-THCA). In total, 246 samples of normal thyroid tissue, 26 FAs, 30 FTCs, 181 follicular variant PTCs, 481 classic variant PTCs and 49 ATCs were examined. In silico validation was performed. Potential biological functions were assessed by enrichment analysis of coexpressed genes. Results. LncRNAs differentially expressed in FA, FTC, follicular, and classical variants of PTC, and ATC are identified. There are 8 lncRNAs common for all investigated thyroid nodules, 22 common for PTC, 32 specific for classical PTC, 1 specific for follicular variant of PTC, and 177 specific for ATC. No lncRNA significantly differentially expressed in FTC compared to FA is identified. The previously described oncogenic and suppressor lncRNAs NR2F1-AS1, LINC00511, SLC26A4-AS1, CRNDE, RMST are detected in thyroid carcinomas for the first time. Identified lncRNA are putatively involved in cell adhesion, extracellular matrix organization, endoderm formation, VEGF signaling pathway, WNT signaling pathway and cell polarity, cell cycle and mitosis. Conclusion. The general and specific patterns of lncRNA expression in benign and malignant thyroid nodules are established.

Abstract β-1,4-mannosylglycoprotein 4-β-N-acetylglucosaminyltransferase (MGAT3) is a key molecule for the innate immune system. We tested the hypothesis that intronic antisense long non-coding RNA, MGAT3-AS1, can predict delayed allograft function after kidney transplantation. We prospectively assessed kidney function and MGAT3-AS1 in 129 incident deceased donor kidney transplant recipients before and after transplantation. MGAT3-AS1 levels were measured in mononuclear cells using qRT-PCR. Delayed graft function was defined by at least one dialysis session within 7 days of transplantation. Delayed graft function occurred in 22 out of 129 transplant recipients (17%). Median MGAT3-AS1 after transplantation was significantly lower in patients with delayed graft function compared to patients with immediate graft function (6.5 × 10−6, IQR 3.0 × 10−6 to 8.4 × 10−6; vs. 8.3 × 10−6, IQR 5.0 × 10−6 to 12.8 × 10−6; p < 0.05). The median preoperative MGAT3-AS1 was significantly lower in kidney recipients with delayed graft function (5.1 × 10−6, IQR, 2.4 × 10−6 to 6.8 × 10−6) compared to recipients with immediate graft function (8.9 × 10−6, IQR, 6.8 × 10−6 to 13.4 × 10−6; p < 0.05). Receiver-operator characteristics showed that preoperative MGAT3-AS1 predicted delayed graft function (area under curve, 0.83; 95% CI, 0.65 to 1.00; p < 0.01). We observed a positive predictive value of 0.57, and a negative predictive value of 0.95. Long non-coding RNA, MGAT3-AS1, indicates short-term outcome in patients with deceased donor kidney transplantation.

SummarySpecialized adipocytes localized in distinct depots mediate the many physiological functions of adipose tissue. In humans, paucity of thermogenic adipocytes correlates with high metabolic disease risk, raising much interest in the mechanisms by which these cells arise. Here we report molecular signatures associated with adipocyte development in different human depots and identify a long non-coding RNA, LINC00473, as the transcript most closely associated with enrichment of thermogenic adipocytes. LINC00473 expression is low in subjects with obesity or type-2 diabetes and is highly correlated with cAMP signaling and mitochondrial oxidative phosphorylation pathways. LINC00473 is localized in the nucleus and the cytoplasm, and its knockdown impairs induction of UCP1 and mitochondrial respiration. These results reveal that depot-enriched genes that modulate responsiveness to external stimuli, specifically LINC00473, are important determinants of the adipose tissue thermogenic phenotype, and potential targets for metabolic disease therapy.
