Project description:F. nucleatum is an opportunistic pathogen that usually colonize in oral cavity, thereby closely associated with the development of periodontitis.However, the immune regulation mechanism of F. nucleatum to macrophage’s function in disease progress has not been clearly elucidated.Long non-coding RNA (lncRNA) and circular RNA (circRNA) were discovered to play an important role in regulating occurrence and progression of many diseases and identified as effective biomarkers for diagnosis and prognosis of several diseases. In the present study, the expression profiles of mRNA, lncRNA and circRNA associated with F. nucleatum infection were investigated for the first time. The results revealed that the expressions of 375 mRNAs, 64 lncRNAs, and 180 circRNAs were altered during F. nucleatum infection. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) biological pathway analysis showed that the target genes were mainly involved in the MAPK signaling pathway, Toll-like receptor signaling pathway, NF-kappa B signaling pathway and apoptosis. Conclusions: The present study firstly provides the expression profiles of mRNAs, lncRNAs and circRNAs during F. nucleatum infection, and describes a novel perspective on the potential roles of lncRNAs and circRNAs underlying the pathogenesis mechanism of F. nucleatum infection.

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.

Project description:Oral carcinogenesis is a multi-step process involving normal mucosa progressing to oral precancerous lesions and finally to oral squamous cell carcinoma (OSCC). This complex process encompasses various molecules, including non-coding RNAs (ncRNAs). In this study, we performed whole-transcriptome analyses on adjacent normal tissues, oral leukoplakia tissues, and OSCC tissues, with the goal of identifying key differentially expressed circRNAs, lncRNAs, miRNAs, and mRNAs associated with different stages of oral carcinogenesis. In our study, numerous differentially expressed circRNAs, lncRNAs, miRNAs, and mRNAs were identified in adjacent normal, oral leukoplakia, and OSCC tissues. Subsequently, we constructed two regulatory competitive endogenous RNA (ceRNA) networks and identified some potential critical molecules involved in oral carcinogenesis. In conclusion, based on the whole-transcriptome analyses, we mapped the molecular feathers at RNA level during the process of oral carcinogenesis and revealed certain ncRNAs with great research potential.

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.

Project description:Background: Cryptosporidium baileyi is the most common Cryptosporidium species in birds. However, effective prevention measures and treatment for C. baileyi infection were less understood. Long non-coding RNA (lncRNA) and circular RNA (circRNA) were discovered to play an important role in regulating occurrence and progression of many diseases and identified as effective biomarkers for diagnosis and prognosis of several diseases. In the present study, the expression profiles of mRNA, lncRNA and circRNA associated with C. baileyi infection were investigated for the first time. Results: The tracheal tissues of experimental (C. baileyi infection) and control chickens were collected for deep RNA sequencing, and 545,479,934 clean reads were obtained. Of them, 1376 novel lncRNAs were identified, including 1161 long intergenic non-coding RNAs (lincRNAs) and 215 anti-sense lncRNAs. 124 lncRNAs were found to be significantly differentially expressed between experimental and control groups. Additionally, 14,698 mRNAs and 9085 circRNAs were identified, and significantly different expressions were observed for 1317 mRNAs and 104 circRNAs between two groups. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of their targets and background genes suggested that these dysregulated genes would be involved in the interaction between host and C. baileyi. Conclusions: The present study firstly provides the expression profiles of mRNAs, lncRNAs and circRNAs during C. baileyi infection, and describes a novel perspective on the potential roles of lncRNAs and circRNAs underlying the pathogenesis mechanism of Cryptosporidium infection.

Project description:Subcutaneous preadipocyte differentiation play a critical role in fat deposition of pigs. However, the action of different RNAs in subcutaneous preadipocyte differentiation, such as messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), are still largely unclear. In the present study, a transcriptome analysis including mRNAs, lncRNAs, and circRNAs was performed in different stages of D0, D2, D4, and D8 using RNA-seq technology. Our results identified 1,554, 470, 1,344, 1,777, and 676 differentially expressed (DE) mRNAs, 112, 58, 95, 136, and 93 DE lncRNAs, and 902, 787, 710, 932, and 850 DE circRNAs between D2 and D0, between D4 and D2, between D8 and D4, between D4 and D0, and between D8 and D0, respectively. Moreover, functional enrichment analysis showed that the common DE mRNAs during entire differentiation were mainly involved in lipid metabolic and cell differentiation processes. Additionally, co-expression network analysis identified the potential lncRNAs related to adipogenesis, e.g., MSTRG.42239 and MSTRG.146410. Taken together, this study provides a genome-wide landscape of RNA expression profiles during subcutaneous preadipocyte differentiation, thus improving our understanding of molecular mechanism in regulating subcutaneous adipogenesis of pigs.

Project description:To systematically evaluate the whole-transcriptome sequencing data of cholangiocarcinoma (CHOL) to gain more insights into the transcriptomic landscape and molecular mechanism of this cancer, we performed whole-transcriptome sequencing based on the tumorous (C) and their corresponding non-tumorous adjacent to the tumors (CP) from eight CHOL patients. Subsequently, differential expression analysis was performed on the C and CP groups, followed by functional interaction prediction analysis to investigate gene-regulatory circuits in CHOL. In addition, The Cancer Genome Atlas (TCGA) for CHOL data was used to validate the results. In total, 2,895 differentially expressed messenger RNAs (dif-mRNAs), 56 differentially expressed microRNAs (dif-miRNAs), 151 differentially expressed long non-coding RNAs (dif-lncRNAs), and 110 differentially expressed circular RNAs (dif-circRNAs) were found in CHOL samples compared with controls. Enrichment analysis on those differentially expressed genes (DEGs) related to miRNA, lncRNA, and circRNA also identified the function of spliceosome. The downregulated hsa-miR-144-3p were significantly enriched in the competing endogenous RNA (ceRNA) complex network, which also included 7 upregulated and 13 downregulated circRNAs, 7 upregulated lncRNAs, and 90 upregulated and 40 downregulated mRNAs. Moreover, most of the DEGs and a few of the miRNAs (such as hsa-miR-144-3p) were successfully validated by TCGA data. The genes involved in RNA splicing and protein degradation processes and miR-144-3p may play fundamental roles in the pathogenesis of CHOL.
