Background. Bullous pemphigoid (BP) is a common T helper 2- (Th2-) dominated autoimmune blistering skin disease with significant mortality. MicroRNAs (miRNAs), which are endogenous noncoding RNA molecules, have been reported to be potential biomarkers for some autoimmune diseases; however, to date, there exist no reports on serum expression profiles of miRNAs in BP patients. Methods. A RNA quantitative PCR- (qPCR-) based array was conducted on sera from 20 active BP patients and 20 healthy controls for screening of miRNAs. Significantly dysregulated miRNAs were validated with use of qPCR as performed on sera samples of 45 active BP patients and 60 healthy controls. Serum CCL17, anti-BP180, and anti-BP230 levels were measured with use of ELISA. Results. Relative baseline expression levels of serum miR-1291 were significantly upregulated in the 45 BP patients as compared with the 60 healthy controls (P<0.001) and significantly decreased in the disease control stage (n=13, P=0.006). In addition, these baseline miR-1291 levels showed a significant positive correlation with the baseline levels of serum CCL17 (P<0.001) and anti-BP180 (n=38, P=0.024). Like that observed for miR-1291, baseline levels of serum CCL17 were also significantly elevated in the 45 BP patients compared with the 60 healthy controls (P<0.001) and significantly decreased in the disease control stage (n=13, P=0.002). However, for anti-BP180, baseline serum levels were significantly elevated in only 38 of the 45 BP patients and significantly decreased in the disease control stage (n=10, P=0.004). Conclusions. Relative expression levels of serum miR-1291 can reflect disease activity of BP. miR-1291 may function as an important new serum biomarker for BP.

Introduction: The noncoding RNAs (ncRNAs) play a role in biological processes of various cancers including gliomas. The majority of these transcripts are uniquely expressed in differentiated tissues or specific glioma types. Pediatric oligodendroglioma (POG) is a rare subtype of diffuse glioma and accounts for <1% of pediatric brain tumors. Because histologically POG resembles adult OG, the same treatment is applied as adults. However, the significance in predicting outcomes in POG patients is unclear. In this study, we aimed to investigate the prognostic significance of expression ­profiles of microRNA (miRNA) and long noncoding RNA ­(LncRNA) in POGs. Methods: We investigated the levels of 13 known miRNAs and 6 LncRNAs in tumor samples from 9 patients with primary POG by using RT-PCR and analyzed their association with outcomes. Results: The expression levels of miR-21, miR-106a, miR-10b, and LncRNA NEAT1 were higher, and the expression level of miR-143 was lower in POG tissues compared with normal brain tissues (p = 0.006, p = 0.032, p = 0.034, p = 0.002, and p = 0.001, respectively). High levels of NEAT1 and low expression of miR-143 were associated with decreased probability of short disease-free survival (p = 0.018 and p = 0.022, respectively). Discussion: NEAT1 and miR-143 levels could serve as reciprocal prognostic predictors of disease progression in patients with POG. New treatment models to regulate the expression levels of NEAT1 and miR-143 will bring a new approach to the therapy of POG.

Abstract Introduction.: There is no effective and reliable biomarker to distinguish benign thyroid nodules (BTN) from papillary thyroid carcinomas (PTC). In this study we analyzed a set of four miRNA molecules in plasma of patients with papillary thyroid cancer, benign nodules and healthy controls to identify miRNA molecules that may be markers of PTC.Aim.: We aimed to investigate the dysregulation of plasma miRNAs in PTC and evaluate the diagnostic value for differentiation of PTC from BTN. Methods.: The expression levels of 4 miRNAs (miR-221, miR-222, miR-146b, miR-21) were measured in 48 PTC patients before thyroidectomy and again after thyroidectomy in a subgroup of 36 patients. Preoperative and postoperative plasma miRNA expression levels were compared with baseline levels established in plasma from the heathy controls group (N=57) and patients with BTN (N=22). MicroRNA-222 and miR-146b, miR-221, miR-21 were included in a panel because they all reportedly were overexpressed in PTC compared to benign nodules or normal thyroid tissue.Results.: Compared with baseline levels in the healthy controls group, miR-221, miR-222, miR-146b, miR-21 levels were significantly higher in the preoperative PTC group (P &lt;0.0001, P=0.002, P=0.028, P =0.021, respectively). A significant reduction in miR-21 expression was observed in postoperative PTC patients. MiR-21 decreased by 5.98-fold (P=0.046) in post- operative samples compared with preoperative samples in the PTC patients.In comparison MiRNRs expression levels in BTN group with healthy controls, miR-221, miR-21 expression levels were significantly higher in the BTN group (P=0.003, P=0.048, respectively). No significant difference was observed between the preoperative PTC group and the preoperative BTN group with regard to the expression of these four miRNA’s. Conclusions: The expression levels of miR-222, miR-146b in plasma were significantly higher in patients who had PTC than in healthy volunteers, whereas levels of miR-221, miR-21 in plasma were significantly higher in patients who had either PTC or BTN before thyroidectomy than in healthy volunteers. Furthermore, miR-21 showed a significant reduction of expression levels after thyroidectomy in PTC patients. However, value of these four miRNAs is still limited in differential diagnosis of PTC and benign nodules.

Background. Colorectal cancer (CRC), the most common malignancy worldwide, causes inflammation. We explored the inflammatory pathophysiology of CRC by assessing the peripheral blood parameters. Methods. The differences in gene expression profiles of whole blood cells and cell subpopulations between CRC patients and healthy controls were analyzed using DNA microarray. Serum cytokine/chemokine concentrations in CRC patients and healthy controls were measured via multiplex detection immunoassays. In addition, we explored correlations between the expression levels of certain genes of peripheral CD4+ cells and serum chemokine concentrations. Results. The gene expression profiles of peripheral CD4+ cells of CRC patients differed from those of healthy controls, but this was not true of CD8+ cells, CD14+ cells, CD15+ cells, or CD19+ cells. Serum IL-8 and eotaxin-1 levels were significantly elevated in CRC patients, and the levels substantially correlated with the expression levels of certain genes of CD4+ cells. Interestingly, the relationships between gene expression levels in peripheral CD4+ cells and serum IL-8 and eotaxin-1 levels resembled those of monocytes/macrophages, not T cells. Conclusions. Serum IL-8 and eotaxin-1 concentrations increased and were associated with changes in the gene expression of peripheral CD4+ cells in CRC patients.

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is known as a rare disease characterized by inflammatory lesions on bones and skin. Polymorphism of clinical manifestation and lack of molecular biomarkers have both limited its diagnosis. Our study performed RNA sequencing (RNA-seq) and integrative bioinformatics analysis of long noncoding RNA (lncRNA)-messenger RNA (mRNA) profile in patients with SAPHO syndrome and healthy controls. A total of 4,419 differentially expressed (DE) mRNAs and 2,713 lncRNAs were identified (p &lt; 0.05, fold change &gt; 2) and a coexpression network was constructed to further investigate their regulatory interactions. The DE lncRNAs were predicted to interact with mRNAs in both cis and trans manners. Functional prediction found that the lncRNA-targeted genes may function in SAPHO syndrome by participating in biological process such as adipocytokine signaling pathway, ErbB signaling pathway, FoxO signaling pathway, as well as production and function of miRNAs. The expression levels of three pairs of coexpressed lncRNA-mRNAs were validated by qRT-PCR, and their relative expression levels were consistent with the RNA-seq data. The deregulated RNAs GAS7 and lnc-CLLU1.1-1:2 may serve as potential diagnostic biomarkers, and the combined receiver operating characteristic (ROC) curve of the two showed more reliable diagnostic ability with an AUC value of 0.871 in distinguishing SAPHO patients from healthy controls. In conclusion, this study provides a first insight into long noncoding RNA transcriptome profile changes associated with SAPHO syndrome and inspiration for further investigation on clinical biomarkers and molecular regulators of this inadequately understood clinical entity.

Abstract Objectives Coronavirus disease 2019 (COVID-19) is a kind of viral pneumonia which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). MicroRNAs (miRNA) are small non-coding RNAs consisting of 19–25 nucleotides and play a role in post-transcriptional gene regulation. We have focused on serum expression levels of microRNA (miRNA) a novel concept of in host–virus interactions. MicroRNA expression profiles were investigated in serum samples of COVID-19 patients. Materials and methods The samples were collected from 40 patients diagnosed with COVID-19 patients and from 10 healthy controls. Expression profile of 20 miRNAs were examined using a quantitative real-time polymerase chain reaction (qPCR). Results Statistically significant expression level differences (p < 0.05) were detected in nine miRNAs in COVID-19 patients and healthy controls. 7 miRNAs (hsa-let-7d, hsa-miR-17, hsa-miR-34b, hsa-miR-93, hsa-miR-200b, hsa-miR-200c, hsa-miR-223) expression levels were found to be significantly decreased and the expression levels of 2 miRNAs (hsa-miR-190a and hsa-miR-203) significantly increased respect to healthy controls. Conclusions We expect that a miRNA profile can be beneficial for the diagnosis of the COVID-19. Our result revealed that the increase in hsa-miR-190a level may be a prognostic factor related to the COVID-19 disease.

Pluripotent stem cells are increasingly used for therapeutic models, including transplantation of neural progenitors derived from human embryonic stem cells (hESC). Recently, long noncoding RNA (lncRNA), including Maternally Expressed Gene 3 (MEG3) derived from the DLK1-DIO3-imprinted locus, were found to be expressed during neural developmental events. Their deregulations are associated with various neurological diseases. The DLK1-DIO3-imprinted locus encodes abundant noncoding RNA (ncRNA) that are regulated by differential methylation on the locus. The aim of our research was to study the correlation between the DLK1-DIO3-derived ncRNA and the capacity of hESC neural lineage differentiation. We classified hESC into MEG3-ON and MEG3-OFF based on the expression levels of MEG3 as well as its downstream microRNA by qRT-PCR. Initial embryoid body (EB) formation was conducted to examine the 3 germ layer's differentiation ability. Complementary DNA microarray was used to analyse the gene expression profiles of hESC. Directed neural lineage differentiation was performed, followed by analysis of neural lineage marker expression levels and neurite formation via qRT-PCR and immunocytochemistry methods to investigate the capacity of neural differentiation in MEG3-ON and MEG3-OFF hESC. As for statistics, error bars indicate standard error of the mean. Student's t-test was used for calculating P-values, and a P-value of less than 0.05 was considered to be significant. Our results showed that MEG3-ON and MEG3-OFF hESC differed greatly in DLK1-DIO3-derived ncRNA expression levels, but had comparable pluripotency gene expression profiles. Genes related to nervous system development and neural cancers were differentially expressed in MEG3-OFF hESC, where DLK1-DIO3-derived ncRNA were repressed compared to MEG3-ON ones before differentiation. In neural lineage-like cells derived from MEG3-OFF hESC, lower expression levels of neural lineage markers and impaired neurite formation were observed compared to MEG3-ON hESC at the same time points after differentiation. We suggest that the expression of DLK1-DIO3-derived lncRNA, MEG3, can be used as a simple and effective screening criterion for identifying MEG3-ON hESC with activation of DLK1-DIO3-imprinted ncRNA as starting materials to benefit neural lineage-associated studies.

Glioblastoma (GB) represents the most common malignant brain tumor, which, despite extensive research, remains of poor prognosis. The focus of recent studies of GB pathogenesis has shifted to the study of the role of noncoding RNAs (ncRNAs). In this study, we examined the expression levels of the microRNA miR-326 and the long ncRNA H19 (on which a miR-326 putative binding site was found by in-silico analysis) in brain tumor tissue from GB patients as compared to cancer-free brain tissue. Relative expression levels of miR-326 were not found to be significantly altered in GB patients. By comparison, H19 was consistently over-expressed in all GB patients (p < 0.001), and correlated with poorer overall survival (OS) and progression-free survival (PFS) (p = 0.026 and p = 0.045, respectively). At a cutoff value of 5.27, H19 up-regulation could predict OS in GB patients, with a 71.4% sensitivity and 59.6% specificity (p = 0.026). The current GB patients were clustered by the multivariate analysis into 4 groups based on miR-326 and H19 expression profiles, age at diagnosis, and PFS. Our data suggest a role for H19 in the pathogenesis of GB and could be a potential prognostic biomarker for GB.

Degeneration of sympathetic innervation of the heart occurs in numerous diseases, including diabetes, idiopathic REM sleep disorder, and Parkinson’s disease (PD). In PD, cardiac sympathetic denervation occurs in 80-90% of patients and can begin before the onset of motor symptoms. Today, there are no disease-modifying therapies for cardiac sympathetic neurodegeneration, and biomarkers are limited to radioimaging techniques. Analysis of expression levels of coding mRNA and noncoding RNAs, such as microRNAs (miRNAs), can uncover pathways involved in disease, leading to the discovery of biomarkers, pathological mechanisms, and potential drug targets. Whole blood in particular is a clinically relevant source of biomarkers, as blood sampling is inexpensive and simple to perform. Our research group has previously developed a nonhuman primate model of cardiac sympathetic denervation by intravenous administration of the catecholaminergic neurotoxin 6-hydroxydopamine (6-OHDA). In this rhesus macaque (Macaca mulatta) model, imaging with positron emission tomography showed that oral administration of the peroxisome proliferator-activated receptor gamma (PPARγ) agonist pioglitazone (n=5; 5 mg/kg daily) significantly decreased cardiac inflammation and oxidative stress compared to placebo (n=5). Here, we report our analysis of miRNA and mRNA expression levels over time in the whole blood of these monkeys. Differential expression of three miRNAs was induced by 6-OHDA (mml-miR-16-2-3p, mml-miR-133d-3p, and mml-miR-1262-5p) and two miRNAs by pioglitazone (mml-miR-204-5p and mml-miR-146b-5p) at 12 weeks posttoxin, while expression of mRNAs involved in inflammatory cytokines and receptors was not significantly affected. Overall, this study contributes to the characterization of rhesus coding and noncoding RNA profiles in normal and disease-like conditions, which may facilitate the identification and clinical translation of biomarkers of cardiac neurodegeneration and neuroprotection.

Abstract BackgroundCoronavirus disease 2019 (COVID-19) has brought major harm and challenges to the world. Although many studies have suggested that IFN-I could affect the life cycle of the virus by regulating the expression level of microRNAs, the expression characteristics of plasma IFN-I signaling-related miRNAs at the acute and recovery phase of COVID-19 remain unclear.MethodsDemographic characteristics and fasting blood samples were collected from the acute and recovery phases of 29 COVID-19 patients and 29 healthy controls matched by age (± 5years) and gender (1:1). Expression levels of 12 IFN signaling-related miRNAs were analyzed using RT-qPCR. The receptor-binding domain (RBD) IgG antibody in the convalescent plasma samples was detected using competitive ELISA.ResultsCompared with healthy controls, patients with COVID-19 presented increased levels of miR-29b-3p (~ 5.91-fold), miR-497-5p (~ 2.28-fold), and miR-1246 (~ 7.97-fold), and decreased expression levels of miR-186-5p (~ 6.39-fold) and miR-15a-5p (~ 3.26-fold) at the acute phase of infection. However, the expression levels of miR-29b-3p and miR-1246, which significantly elevated at the acute phase, were not different between individuals at the recovery phase and healthy controls. The expression levels of miR-30b-5p, miR-497-5p, miR-409-3p and miR-548c-5p in convalescent plasma samples were significantly lower than those in healthy controls. However, the concentration of miR-186-5p in the convalescent plasma samples was significantly higher than that in healthy controls and patients with acute infection. Furthermore, competitive ELISA results showed that the plasma level of miR-497-5p at the acute phase positively correlated with RBD-IgG antibody response (r=0.48, P=0.038).ConclusionsThe present study firstly reported that timely and appropriate regulation of IFN signaling-related miRNA expression plays a critical role during both acute and recovery phase of SARS-CoV-2 infection. Furthermore, the circulating miR-497-5p level was positively correlated to RBD-IgG antibody response in COVID-19 patients.
