Distinct mRNA and Long Non-coding RNAs (lncRNAs) Expression Profiles of Decidual Natural Killer Cells in Human Early Missed Abortion

ABSTRACT: Our present study analyzes decidual natural killer(dNK) cells expression profiles of the lncRNA and mRNA in missed abortional patients. A total of 276 mRNAs and 67 lncRNAs were identified to be significantly dysregulated in missed abortion (p<0.01). Subsequently, the potential function of dysregulated mRNAs and lncRNAs in missed abortion were explored through the bioinformatics method. In addition, the relationship between these dysregulated lncRNAs and mRNAs was revealed through constructing the lncRNA-mRNA interaction network. Our data showed that upregulated mRNAs were enriched in immune response and cytokine-cytokine receptor interaction while downregulated mRNAs were mainly related to cell adhesion and ECM-receptor interaction. Most importantly, several novel lncRNAs in dNKs, regulating core maternal-fetal interface activation-related mRNAs, were algorithmically predicted, indicating involvement of lncRNAs in the pathogenesis in early missed abortion.Topology analysis of lncRNA-mRNA interaction network suggested that the network presented a small world property, which means that most of mRNAs in the network were regulated by relative small number of hub lncRNAs. This study paves the way of investigating pathogenesis of early human missed abortion and facilitating the development of novel missed abortion therapeutics targeting lncRNAs.

Genome-wide profiling of long noncoding RNA expression patterns in chemoresistant breast cancer cells

Project description:Long non-coding RNAs (lncRNAs) are involved in cancer progression. In this study, the lncRNA profiling were analyzed in chemoresistant and sensitive breast cancer cells. We found a group of dysregulated lncRNAs in chemoresistant cells. Expression of dysregulated lncRNAs are correlated with dysregulated mRNAs, and enriched in GO and KEGG pathways related with cancer progression and chemoresistance development. Within those lncRNA-mRNA interactions, some lncRNAs may cis-regulate neighboring protein coding genes and involved in chemoresistance. The lncRNA NONHSAT028712 was then validated to regulate nearby CDK2 and interfere with cell cycle and chemoresistance. Furthermore, we identified another group of lncRNAs trans-regulated gene expression via interacting with different transcription factors (TF). Whereby NONHSAT057282 and NONHSAG023333 was found to modulate chemoresistance and most likely interacted with ELF1 and E2F1 respectively. In conclusion, this study reported for the first time the lncRNA expression patterns in chemoresistant breast cancer cells, and provided a group of novel lncRNA targets in mediating chemoresistance development in both cis- and trans- action mode.

Project description:The goals of this study are to analysis the potential regulatory roles in ox-LDL induced macrophage-derived foam cells by lncRNA. A total of 50688 mRNA and 1514 lncRNA were found, and including 51 lncRNAs and 1730 mRNAs were significantly dysregulated in the model group (p-adjust < 0.05 and |log2FC| > 2). Then the result of GO and KEGG pathways showed that this dysregulated genes were significantly enriched in molecular function and biological processes and they were associated cell proliferation, cell apoptosis and inflammatory response. Additionally, the results of the lncRNA-mRNA co-expression network showed that 15 mRNAs and 9 lncRNAs were identified as the key regulatory factors, which may play crucial roles in AS development. Especially, the lncRNAs, Brip1os, Gm15472, Gm16586, Gm20703, and AU020206 could be seen as the potential biomarkers in macrophage-derived foam cells. This study revealed the dysregulated lncRNAs and mRNAs in AS development and the lncRNAs, Brip1os, Gm15472, Gm16586, Gm20703, and AU020206 were identified as the key regulatory factors. The dysregulated genes may be consider as the potential diagnostic biomarkers of AS, and it needs more verification in future studies.

LncRNA and circRNA expression profiles of Aβ25-35-induced AD mice hippocampus treated with Tripterygium Glycoside

Project description:Tripterygium glycosides (TG) was reported to have effect of ameliorating Alzheimer's disease (AD). However, the mechanism is not clear. We aimed to investigate the lncRNAs and circRNAs expression profiles of AD treated with TG by using microarray. LncRNAs, mRNA and circRNA in 3 AD mice and 3 AD+TG mice hippocampal were detected by microarray. The most differentially expressed lncRNAs, mRNA and circRNA in AD+TG group were screened. The differentially expressed lncRNAs and circRNAs were analyzed for GO enrichment and KEGG pathway. Co-expression analysis of lncRNAs and mRNA was performed by calculating correlation coefficients. Protein-protein interaction (PPI) network analysis was performed on mRNAs using STRING. LncRNA-target-TFs network were analyzed by Network software. CircRNA-mirNA network were conducted by Cytoscape software. A total of differentially expressed 661 lncRNAs, 64 circRNAs and 503 mRNAs were detected in AD mice treated with TG. The Pou4f1, Egr2, Mag, and Nr4a1 were the hub genes in the PPI network. The KEGG results showed the mRNAs that co-expressed with lncRNAs were enriched in TNF, PI3K-Akt, and Wnt signaling pathway. lncRNA-target-TFs network analysis indicated the TFs including Cebpa, Zic2, and Rxra were the most likely to regulate the detected lncRNAs. The circRNA-miRNA interaction network indicated 275 miRNAs may bind to the 64 circRNAs. In conclusion, the findings supplied a novel perspective for AD pathogenesis. And the detected lncRNAs, mRNAs, and circRNAs might be novel therapeutics targets for AD.

Integrated analysis of genome-wide profiling of lncRNA and mRNA expression and functional networks after botulinum toxin type A injection into submandibular gland of rats.

Project description:Abstract: Backgroud: This study was to explore long noncoding RNA (lncRNA) and messenger RNA (mRNA) expression profiles and construct functional networks to analyze their biological functions when botulinum toxin type A (BTXA) inhibited salivary secretion. Methods: BTXA and saline were injected into the submandibular gland of rats as the BTXA group and control group, respectively. Morphological and secretory function tests validated the animal models. Microarray analysis was applied to identify the expression variation of lncRNA and mRNA and were confirmed by qRT-PCR. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to explicit the biological functions. The construction of functional networks including lncRNA-mRNA co-expression network and competing endogenous RNA (ceRNA) network was to reveal the interaction between coding and noncoding genes. Results: A total of 254 lncRNAs and 631 mRNAs were differentially expressed (DE) between the control group and the BTXA group. Ten lncRNAs and eleven mRNAs were confirmed by qRT-PCR and the results were consistent with the microarray analysis. The bioinformatic analysis found that most of mRNAs were closely related to transmembrane transporter activity. LncRNA-mRNA co-expression network and ceRNA network were constructed and identified several critical mRNA-lncRNA axes and key microRNAs related to salivary secretion, respectively. Conclusions: Our study identified DE lncRNAs and mRNAs through microarray analysis and explored the biological functions and interaction between coding and noncoding genes through bioinformatics analysis. These findings may provide new directions for the mechanism of BTXA to inhibit salivary secretion.

Polyadenylated RNA Sequencing of C57BL/6J Embryonic, Adult and Pressure-Overloaded Hearts

Project description:A few reports have implicated specific lncRNAs in cardiac development or failure, but precise details of lncRNAs expressed in hearts and how their expression may be altered during embryonic heart development or by adult heart disease is unknown. By comparing lncRNA profiles of normal embryonic (~E14), normal adult, and hypertrophied adult hearts we defined a distinct fetal lncRNA abundance signature that includes 157 lncRNAs differentially expressed compared to adults (fold-change ≥ 50%, FDR=0.02), and which was only poorly recapitulated in hypertrophied hearts (17 differentially expressed lncRNAs; 13 of these observed in embryonic hearts). Analysis of protein-coding mRNAs from the same samples identified 22 concordantly and 11 reciprocally regulated mRNAs within 10 kb of dynamically expressed lncRNAs, reciprocal relationships of lncRNA and mRNA levels was validated for the Mccc1 and Relb genes using in vitro lncRNA knockdown in C2C12 cells. Network analysis suggested a central role for lncRNAs in modulating NFkappaB- and CREB1-regulated genes during embryonic heart growth and identified multiple mRNAs within these pathways that are also regulated, but independently of lncRNAs. Cardiac polyadenylated RNA (mRNA and lncRNA) profiles were generated from C57BL/6J mouse hearts were generated on Illumina HiSeq 2000 instruments. 7 independent E13.5 hearts, 12 adult hearts (6 at 6 weeks of age, 6 at 16 weeks of age), 4 sham-operated hearts at 12 weeks of age, and 4 hearts after 4 weeks of pressure overload (TAC) at 12 weeks of age.

Intersectional analysis of chronic mild stress-induced lncRNA-mRNA interaction networks in rat hippocampus reveals potential anti-depression/anxiety drug targets

Project description:Despite studies providing insight into the neurobiology of chronic stress, depression and anxiety, long noncoding RNA (lncRNA)-mediated mechanisms underlying the common and distinct pathophysiology of these stress-induced disorders remain nonconclusive. In a previous study, we used the chronic mild stress paradigm to separate depression-susceptible, anxiety-susceptible and insusceptible rat subpopulations. In the current study, lncRNA and messenger RNA (mRNA) expression was comparatively profiled in the hippocampus of the three stress groups using microarray technology. Groupwise comparisons identified distinct sets of lncRNAs and mRNAs associated with the three different behavioral phenotypes of the stressed rats. To investigate the regulatory roles of the dysregulated lncRNAs upon mRNA expression, correlations between the differential lncRNAs and mRNAs were first analyzed by combined use of weighted gene coexpression network analysis and ceRNA theory-based methods. Subsequent functional analysis of strongly correlated mRNAs indicated that the dysregulated lncRNAs were involved in various biological pathways and processes to specifically induce rat susceptibility or resiliency to depression or anxiety. Further intersectional analysis of phenotype-associated and drug-associated lncRNA-mRNA networks and subnetworks assisted in identifying 16 hub lncRNAs as potential targets of anti-depression/anxiety drugs. Collectively, our study established the molecular basis for understanding the similarities and differences in pathophysiological mechanisms underlying stress-induced depression or anxiety and stress resiliency, revealing several important lncRNAs that represent potentially new therapeutic drug targets for depression and anxiety disorders.

The long noncoding RNA expression profile of human intervertebral disc degeneration identified by microarray analysis

Project description:In addition to the well-known short noncoding RNAs as miRNAs, increasing evidence suggests that long noncoding RNAs (lncRNAs) act as key regulators in a wide aspect of biologic processes. Dysregulated expression of lncRNAs has been demonstrated being implicated in a variety of human diseases. However, there is relative paucity of information regarding the role of lncRNAs in intervertebral disc degeneration (IDD) hitherto. We have addressed the expression profiles of miRNAs in IDD previously. To determine whether lncRNAs is differentially expressed in IDD, we employed a lncRNA-mRNA microarray analysis of human nucleus pulposus (five degenerative as IDD and five normal specimens as control). With abundant probes accounting for 33,045 lncRNAs and 30,215 coding transcripts in our microarray, microarray data profiling indicated that 18995 lncRNAs and 14635 mRNAs were detected in all samples with 2309 lncRNAs and 3017 mRNAs differentially expressed in degenerated samples. Amongst them, 164 lncRNAs (97 up and 67 down) and 265 mRNAs were highly differentially expressed with an absolute fold change greater than ten. The upregulated mRNAs included the extracellular matrix components as COL1A2, LUM, FN1ACAN, DCN and ITFG2. 1100 lncRNAs and 1379 mRNAs were altered in the same direction in at least 4 of the 5 degenerative samples with fold change greater than 2 respectively. Three lncRNAs were chosen for the real-time quantitative PCR (qRT-PCR) analysis. qRT-PCR results showed a high consistency with the microarray data. In this study, to explore the potential involvement of lncRNAs in IDD, we conducted lncRNA and mRNA profiling in 5 human control nucleus pulposus tissue and 5 degenerative nucleus pulposus tissue by microarray.Biological replicates: 5 control, 5 degenerated, independently harvested.

Identification of exosomal mRNA, lncRNA and circRNA signatures in an osteoarthritis synovial fluid-exosomal study

Project description:Aims Osteoarthritis (OA) is a common degenerative disease that is pathologically characterized by destruction of the joint matrix and reduction of articular chondrocytes, resulting in joint deformity and motor dysfunction. However, the molecular mechanisms governing this pathology have not been fully elucidated to date. Methods In this study, we determined the expression levels of lncRNAs, circRNAs, and mRNAs extracted from synovial exosomes of OA and control patients. A network of circRNA/lncRNA–miRNA–mRNA interactions was established using MiRanda and TargetScan software to explore OA pathogenesis. The exosomal lncRNA, circRNA and mRNA expression profiles of the OA and control groups were analysed using LC human competing endogenous RNA (ceRNA) microarrays. The differentially expressed genes were identified to determine their potential roles in the pathogenesis of OA by bioinformatic analysis. Results Compared with the control group, 11 mRNAs, 52 lncRNAs, and 30 circRNAs were upregulated, while 41 mRNAs, 144 lncRNAs, and 68 circRNAs were downregulated in osteoarthritis synovial exosomes. The final ceRNA network of lncRNAs and circRNAs exhibited a complex interaction between ncRNA and mRNA related to OA pathological mechanisms. An intersection analysis of the ceRNA network showed that 22 miRNAs, 45 lncRNAs, and 34 circRNAs in the PI3K/Akt and autophagy pathways correlated with 7 enriched mRNAs and may play important roles in OA pathological mechanisms. Conclusion Our work analysed mRNA/lncRNA/circRNA expression and displayed the ceRNA network of lncRNAs and circRNAs to profile the pathogenesis of OA in synovial exosomes. The results of this study may help to elucidate the pathogenesis of OA and may provide important references for further research attempting to identify more effective targets for the diagnosis and therapy of OA.

Expression Profiles of Long Non-Coding RNAs and Messenger RNAs in a Rat Model of Spinal Cord Injury

Project description:Spinal cord injury (SCI) is a serious disorder of the central nervous system with a high disability rate. Long non-coding RNAs (lncRNAs) are reported to mediate many biological processes. The aim of this study was to explore lncRNA and mRNA expression profiles and functional networks after SCI.We identified 5465 differentially expressed lncRNAs (DE lncRNAs) and 8366 differentially expressed mRNAs (DE mRNAs) in the SCI group compared with the sham group (fold change >2.0, P<0.05). Four genes were confirmed by real-time PCR which were consistent with the microarray data. GSEA analysis showed that most marked changes occurred in pathways related to immune inflammation and nerve cell function, including cytokine-cytokine receptor interaction (rno04060), TNF signaling pathway (rno04668), neuroactive ligand-receptor interaction (rno04080)，and GABAergic synapse (rno04727). Enrichment analysis identified 30 signaling pathways, including those associated with inflammation and the immune response. A total of 40 key lncRNAs were identified using the SVM-RFE algorithm. A key lncRNA-mRNAs co-expression network was generated for 230 951 lncRNA-mRNA pairs with half showing positive correlations. Several key DE lncRNAs were predicted to have “cis” or “trans”-regulated target genes. The transcription factors, Sp1, JUN, and SOX10, may regulate the interaction between XR_001837123.1 and ETS 1. In addition, five pairs of ceRNA regulatory sequences were identified.
