Genome-wide analysis of RNAs associated with Populus euphratica Oliv. heterophyll morphogenesis [miRNA-Seq]

ABSTRACT: The desert plant Populus euphratica Oliv. has typical heterophylly; linear (Li), lanceolate (La), ovate (Ov) and broad-ovate (Bo) leaves grow in turn from young to adult trees. It is therefore a potential model organism for leaf development. To investigate the roles of RNAs (including mRNAs, miRNAs, lncRNAs and circRNAs) in the morphogenesis of P. euphratica heterophyll, the juvenile heterophyll were respectively sampled, and then their expression patterns were analyzed by small RNA sequencing and strand-specific RNA sequencing. We found that 1374 mRNAs, 19 miRNAs, 71 lncRNAs and 2 circRNAs were P. euphratica heterophyll morphogenesis associated (PHMA) RNAs, among them, 17 PHMA miRNAs could disturb the expression of 46 PHMA mRNAs, furthermore, 11 lncRNAs and 2 circRNAs interacted with 27 PHMA mRNAs by ceRNA hypothesis, respectively. According to GO and KEGG pathway analysis, PHMA RNAs were mainly involved in metabolic, response to stimulus and developmental processes. Our results indicated that both external environmental factors and genetic factors of P. euphratica co-regulated the expression of PHMA RNAs, caused the cell division was repressed, while cell growth was reinforced, and resulted in the morphogenesis of P. euphratica heterophyll, ultimately.

A Genome-Wide Characterization of New and Drought Stress Responsive MicroRNAs in Populus euphratica

Project description:We present an efficient method to genome-wide discover new and drought stress responsive miRNAs in P. euphratica. High throughput sequencing of P. euphratica leaves found 197 conserved miRNAs between P. euphratica and Populus trichocarpa. Meanwhile, 189 new miRNAs which belonged to 120 families were identified, a large increasing to the number of P. euphratica miRNAs. Target prediction and degradome sequencing verification of 22 new and 21 conserved miRNA targets showed these targets were involved in multiple biological processes, including transcription regulation and response to stimulus. Furthermore, comparison of high-throughput sequencing with miRNA microarray profiling data indicated that 104 miRNA sequences were up-regulated, while 27 were down-regulated under drought stress. This preliminary characterization based on our findings provided a framework for future analysis of miRNA genes and their roles in key traits of poplar as stress resistance plant breeding and environment protection usage.

Analyzing the interactions of mRNAs, miRNAs, lncRNAs and circRNAs to predict competing endogenous RNA networks in glioblastoma

Project description:Cross-talk between competitive endogenous RNAs (ceRNAs) may play a critical role in revealing potential mechanisms of tumor development and physiology. Glioblastoma is the most common type of malignant primary brain tumor, and the mechanisms of tumor genesis and development in glioblastoma are unclear. Here, to investigate the role of non-coding RNAs and the ceRNA network in glioblastoma, we performed paired-end RNA sequencing and microarray analyses to obtain the expression profiles of mRNAs, lncRNAs circRNAs and miRNAs. We identified that the expression of 501 lncRNAs, 1789 mRNAs, 2038 circRNAs and 143 miRNAs were often altered between glioblastoma and matched normal brain tissue. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on these differentially expressed mRNAs and miRNA-mediated target genes of lncRNAs and circRNAs. Furthermore, we used a multi-step computational framework and several bioinformatics methods to construct a ceRNA network combining mRNAs, miRNAs, lncRNAs and circRNA, based on co-expression analysis between the differentially expressed RNAs. We identified that plenty of lncRNAs, CircRNAs and their downstream target genes in the ceRNA network are related to glutamatergic synapse, suggesting that glutamate metabolism is involved in glioma biological functions. Our results will accelerate the understanding of tumorigenesis, cancer progression and even therapeutic targeting in glioblastoma. We hope to inspire researchers to study the role of non-coding RNAs in glioblastoma.

circRNA expression in human myometrium during labor

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).

Genome-wide analysis of differentially expressed profiles of mRNAs, lncRNAs and circRNAs in aorta samples of F. nucleatum-infected mice

Project description:Periodontitis is an independent risk factor for atherosclerosis, and F. nucleatum is one of the periodontal pathogens. Several studies have confirmed that non-coding RNAs could affect all aspects of AS disease progression, including lipid metabolism, foam cell formation, cell necrosis, etc. However, no studies have explored whether F. nucleatum could affect AS disease progression by regulating non-coding RNAs. In this study, we intend to acquire mRNAs, lncRNAs and circRNAs expression profiles of aorta samples of AS mice from the F. nucleatum group and the Control group by next-generation sequencing(NGS) and perform bioinformatics analysis. Results revealed that 465 mRNA expression were up-regulated and 382 mRNA expression were down-regulated significantly. Some lncRNAs and circRNAs could suppress the binding of miRNA with target genes in post-transcriptional regulation. By integrating with DE-miRNAs-DEGs pairs and screening the common miRNAs, and mRNAs, lncRNAs, circRNAs that have targeted and negatively correlated relationship with the common miRNAs, lncRNA-miRNA-mRNA (including 34 DE-miRNAs, 42 DE-lncRNAs, and 111 DE-mRNAs) and circRNA-miRNA-mRNA (including 19 DE-miRNAs, 49 DE-circRNAs, and 87 DE-mRNAs) regulatory co-expression networks were constructed. GO enrichment analysis was performed on the differentially expressed mRNAs, which were found to be related to molecular functions, biological processes and cellular components such as protein binding, nucleus, postsynaptic dense zone, protein phosphorylation. KEGG analysis showed that they were related to ErbB signaling pathway, neurotrophic factor signaling pathway, glucagon signaling pathway and apoptosis signaling pathway. This suggested that F. nucleatum could promote the development of atherosclerosis through non-coding RNAs network regulation.
