Project description:The maintenance of coordinated powerful episodic contractions of the uterus is the crucial factor for normal labor. The uterine contractility is gradually enhanced with the progression of labor, which is related to the gene expression of myometrium, competing endogenous RNA (ceRNA) can also regulate the gene expression. To better understand the role of ceRNA network in labor, transcriptome sequencing was performed on the myometrium of 17 parturients at different labor duration. Furthermore, an correlated analysis was performed to identify mRNA, long non-coding RNA (lncRNA), circular RNA (circRNA), and microRNA (miRNA) which correlated with their expression levels and labor duration. Then, targeting relationships between mRNAs, lncRNAs, circRNAs and miRNAs were predicted, and the ceRNA regulatory network was established.This analysis identified 934 RNAs positively correlated with labor duration (859 mRNAs, 28 lncRNAs, 45 circRNAs, and 2 miRNAs) and 153 RNAs negatively correlated with labor duration (122 mRNAs, 28 lncRNAs, and 3 miRNAs).

Project description:this study was designed to acquire mRNA and long non-coding RNA (lncRNA) profiles of 2-cells, 4-cells and blastocysts derived from vitrified porcine cloned zygotes using transcriptome sequencing. We identified 167 differentially expressed (DE) mRNAs and 516 DE lncRNAs in 2-cell stage, 469 DE mRNAs and 565 lncRNAs in 4-cell stage, and 389 DE mRNAs and 816 DE lncRNAs in blastocyst stage. Functional enrichment analysis revealed that DE mRNAs during embryo development were involved in many regulatory mechanisms related to cell cycle, cell proliferation, apoptosis, metabolism and others. Moreover, the target genes of DE lncRNAs in the three embryonic stages were also enriched in many key GO terms or pathways such as ‘defense response’, ‘linoleic acid metabolic process’, ‘embryonic axis specification’, ‘negative regulation of protein neddylation’, etc. In conclusion, the present study provided comprehensive transcriptomic data about mRNA and lncRNA for the vitrified porcine cloned zygotes during different developmental stages, which contributed to further understand the potential cryodamage mechanisms responsible for impaired embryo development.

Project description:Background: Long non-coding RNAs (lncRNAs) are increasingly implicated as gene regulators and may ultimately be more numerous than protein-coding genes in the human genome. Despite large numbers of reported lncRNAs, reference annotations are likely incomplete due to their lower and tighter tissue-specific expression compared to mRNAs. An unexplored factor potentially confounding lncRNA identification is inter-individual expression variability. Here, we characterize lncRNA natural expression variability in human primary granulocytes. Results: We annotate granulocyte lncRNAs and mRNAs in RNA-seq data from ten healthy individuals, identifying multiple lncRNAs absent from reference annotations, and use this to investigate three known features (higher tissue-specificity, lower expression, and reduced splicing efficiency) of lncRNAs relative to mRNAs. Expression variability was examined in seven individuals sampled three times at one or more than one month intervals. We show that lncRNAs display significantly more inter-individual expression variability compared to mRNAs. We confirm this finding in 2 independent human datasets by analyzing multiple tissues from the GTEx project and lymphoblastoid cell lines from the GEUVADIS project. Using the latter dataset we also show that including more human donors into the transcriptome annotation pipeline allows identification of an increasing number of lncRNAs, but minimally affects mRNA gene number. Conclusions: A comprehensive annotation of lncRNAs is known to require an approach that is sensitive to low and tight tissue-specific expression. Here we show that increased inter-individual expression variability is an additional general lncRNA feature to consider when creating a comprehensive annotation of human lncRNAs or proposing their use as prognostic or disease markers. We used PolyA+ RNA-seq data from human primary granulocytes of 10 healthy individuals to de novo annotate lncRNAs and mRNAs in this cell type and ribosomal depleted (total) RNA-seq data from seven of these individuals sampled three times to analyze lncRNA amd mRNA expression variability

Project description:Pseudorabies, an acute infectious disease caused by pseudorabies virus (PRV), has caused enormous economic losses to the breeding industry in many countries worldwide. Accumulating evidence indicates that long non-coding RNAs (lncRNAs) may play important roles in the antiviral responses. However, little is known about the identification and functions of swine lncRNAs in cellular antiviral responses against PRV II. In this study, we detected the expression profiles of host lncRNAs and mRNAs from PRV-DX, a wild-type (WT) strain of PRV II, and its attenuated gE-TK- PRV-DX infected cells by high-throughput RNA sequencing. Finally, we identified differentially expressed (DE) 664 lncRNAs and DE 7,199 mRNAs from PRV-DX infected cells, and 654 DE lncRNAs and DE 7,149 mRNAs from gE-TK- PRV-DX infected cells when compared to MOCK infected cells, respectively, especially including 469 common DE lncRNAs and 5836 DE mRNAs. Besides 276 DE lncRNAs and 2,272 DE mRNAs between PRV-DX and gE-TK- PRV-DX infected cells were identified. The potential functions of the significant DE lncRNAs were involved in interleukin secretion, axon extension and metabolic process based on the Gene ontology and Kyoto Encyclopedia of Genes and Genomes databases. Taken together, results highlighted the potentials of lncRNA as targets for antiviral therapy and enriched the current knowledge of the mechanisms underlying the interaction between PRV II and its host cells.

Project description:Autoimmune pulmonary alveolar proteinosis (APAP) is a rare lung disease which may be closely associated with autoantibody. However, there is little known about the function of long non-coding RNAs (lncRNAs) in APAP.To further investigate the role of lncRNAs in APAP, we screened the differential expression profiles of lncRNAs and mRNAs in peripheral blood samples between five APAP patients and five matched healthy controls. We analyzed the regulatory networks of lncRNA-mRNA and lncRNA-miRNA-mRNA via bioinformatics methods. This study identified differentially expressed (DE) lncRNAs and their potential corresponding mRNAs to provide a basis for the study of APAP pathogenesis.

Project description:Long noncoding RNAs (lncRNAs) are important regulators of cell fate, and their mis-expression has been implicated in many diseases. While distinct polymerases generate messenger vs. noncoding ribosomal or tRNAs3, little is known about distinct mechanisms controlling lncRNA expression. Here we show that transcription of lncRNAs is quantitatively different from that of messenger RNAs (mRNAs)--as revealed by deficiency of Dicer (Dcr), a key ribonuclease that generates microRNAs (miRNAs). Loss of Dcr in mouse embryonic stem cells (mESCs) led surprisingly to decreased level of the majority of lncRNAs. The canonical Dgcr8-Dcr-miRNA pathway is required for robust lncRNA expression, at the level of transcriptional initiation and elongation of lncRNA genes rather than at the level of their stability. cMyc, an oncogenic transcription factor, whose expression is indirectly regulated by Dcr-miRNA in mESCs, is partly responsible for lncRNA transcription. Loss of cMyc led to a more dramatic decrease of lncRNAs than mRNAs, and cMyc overexpression rescues lncRNA expression in Dcr KO cells. A quantitative metric of “mRNA-lncRNA decoupling” revealed that Dcr and cMyc differentially regulate lncRNAs vs. mRNAs in diverse cell types and in vivo, as evidenced by hundreds of microarray experiments. Thus, Dcr and cMyc may allow numerous lncRNAs to be activated or deactivated as a class, implicating lncRNAs to potential regulatory roles in development and disease states where Dcr and cMyc have been associated with. RNA was sequenced from WT and Dcr KO mESCs and the expression of lncRNAs and mRNAs are compared between WT and Dcr KO mESCs.

Project description:We investigated comprehensive transcriptomic change in rat aorta tolerant to nitroglycerin (GTN) with a focus on lncRNAs. We employed RNA sequencing (RNA-seq) technique and identified 22788 genes (RPKM > 0.1, 14720 protein coding and 4408 lncRNA). And 115 differentially expressed (DE) mRNAs (65 upregulated and 50 downregulated) and 104 DE lncRNAs (56 upregulated and 48 downregulated) were found in GTN-tolerant aortas. Many DE mRNAs and cis-target genes of DE lncRNAs have been implicated in regulation of blood pressure or cell contraction. Collectively, these results suggested that dysregulated mRNAs and lncRNAs contribute to the development of GTN tolerance and might be used as novel potential targets to prevent and reverse GTN tolerance.
