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: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:Intensive research in past two decades has uncovered the presence and importance of noncoding RNAs (ncRNAs), which includes microRNAs (miRs) and long ncRNAs (lncRNAs). These two classes of ncRNAs interact to a certain extent, as some lncRNAs bind to miRs to sequester them. Such lncRNAs are collectively called 'competing endogenous RNAs' or 'miRNA sponges'. In this study, we screened for lncRNAs that may act as miRNA sponges using the publicly available data sets and databases. To uncover the roles of miRNA sponges, loss-of-function experiments were conducted, which revealed the biological roles as miRNA sponges. LINC00324 is important for the cell survival by binding to miR-615-5p leading to the de-repression of its target BTG2 LOC400043 controls several biological functions via sequestering miR-28-3p and miR-96-5p, thereby changing the expressions of transcriptional regulators. Finally, we also screened for circular RNAs (circRNAs) that may function as miRNA sponges. The results were negative at least for the selected circRNAs in this study. In conclusion, miRNA sponges can be identified by applying a series of bioinformatics techniques and validated with biological experiments. The expressions of miRs were examined in HEK-293 cells that were LINC00324- or LOC400043-silenced using siRNA.

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: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.
