Objectives: We aimed to investigate the differentially expressed microRNAs (miRNAs) and their target genes in human alcoholic cardiomyopathy (ACM). Methods: The expression levels of plasma miRNAs of 78 male ACM patients and 78 healthy men were detected by using the 6th-generation miRCURY™ LNA array (v.16.0). The prediction analysis for microarrays (PAM) method was used to identify the differentially expressed miRNAs. Target genes of the identified differentially expressed miRNAs were predicted using TargetScan 5.2 and Miranda. Gene ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to perform functional annotation and pathway enrichment analysis of target genes respectively, followed by real-time RT-PCR analysis to validate the expression changes of miRNAs. Results: Twenty-one differentially expressed miRNAs were identified. Nine differentially expressed miRNAs (hsa-miR-506, hsa-miR-1285, hsa-miR-512-3P, hsa-miR-138, hsa-miR-485-5P, hsa-miR-4262, hsa-miR-548c-3P, has-miR-548a-5P and kshv-miR-K12-1), involved in multiple functions and pathways, were selected for real-time RT-PCR confirmation. Moreover, two significantly important subpathways (neurotrophin signaling pathway and inositol phosphate metabolism) were predicted. Conclusion: The screened differentially expressed miRNAs may be involved in the development of ACM. Specific miRNAs, such as miR-138, may be considered as a new target for the early diagnosis and treatment of human ACM.

AbstractWeightlessness-induced cardiovascular dysfunction can lead to physiological and pathological consequences. It has been shown that spaceflight or simulated microgravity can alter expression profiles of some microRNAs (miRNAs). Here, we attempt to identify the role of miRNAs in human umbilical vein endothelial cells (HUVECs) apoptosis under simulated microgravity. RNA-sequencing and quantitative real-time PCR (qRT-PCR) assays were used to identify differentially expressed miRNAs in HUVECs under simulated microgravity. Then we obtained the target genes of these miRNAs through target analysis software. Moreover, GO and KEGG enrichment analysis were performed. The effects of these miRNAs on HUVECs apoptosis were evaluated by flow cytometry, Western blot and Hoechst staining. Furthermore, we obtained the target gene of miR-27b-5p by luciferase assay, qRT-PCR and Western blot. Finally, we investigated the relationship between this target gene and miR-27b-5p in HUVECs apoptosis under normal gravity or simulated microgravity. We found 29 differentially expressed miRNAs in HUVECs under simulated microgravity. Of them, the expressions of 3 miRNAs were validated by qRT-PCR. We demonstrated that miR-27b-5p affected HUVECs apoptosis by inhibiting zinc fingers and homeoboxes 1 (ZHX1). Our results reported here demonstrate for the first time that simulated microgravity can alter the expression of some miRNAs in HUVECs and miR-27b-5p may protect HUVECs from apoptosis under simulated microgravity by targeting ZHX1.

AbstractMicroRNAs (miRNAs) play an important role in regulating gene expression in multiple biological processes and diseases. Thus, to understand changes in miRNA during CVB3 infection, specific miRNA expression profiles were investigated at 3 h, 6 h, and 9 h postinfection in HeLa cells by small-RNA high-throughput sequencing. Biological implications of 68 differentially expressed miRNAs were analyzed through GO and KEGG pathways. Interaction networks between 34 known highly differentially expressed miRNAs and targets were constructed by mirDIP and Navigator. The predicted targets showed that FAM135A, IKZF2, PLAG1, ZNF148, PHC3, LCOR and DYRK1A, which are associated with cellular differentiation and transcriptional regulation, were recognized by 8 miRNAs or 9 miRNAs through interactional regulatory networks. Seven target genes were confirmed by RT-qPCR. The results showed that the expression of DYRK1A, FAM135A, PLAG1, ZNF148, and PHC3 were obviously inhibited at 3 h, 6 h, and 9 h postinfection. The expression of LCOR did not show a significant change, and the expression of IKZF2 increased gradually with prolonged infection time. Our findings improve the understanding of the pathogenic mechanism of CVB3 infection on cellular differentiation and development through miRNA regulation, which has implications for interventional approaches to CVB3-infection therapy. Our results also provide a new method for screening target genes of microRNA regulation in virus-infected cells.

Abstract Background: MicroRNAs (miRNAs) are small non-coding RNAs playing vital roles in regulating posttranscriptional gene expression. Elucidating the expression regulation of miRNAs underlying pig testis development will contribute to a better understanding of boar fertility and spermatogenesis. Results: In this study, miRNA expression profile was investigated in testes of Duroc and Meishan boars at 20, 75, and 270 days of age by high-throughput sequencing. Forty-five differentially expressed miRNAs were identified from testes of Duroc and Meishan boars before and after puberty. Integrated analysis of miRNA and mRNA profiles predicted many miRNA-mRNA pairs. Gene ontology and biological pathway analyses revealed that predicted target genes of ssc-mir-423-5p, ssc-mir-34c, ssc-mir-107, ssc-165 mir-196b-5p, ssc-mir-92a, ssc-mir-320, ssc-mir-10a-5p, and ssc-mir-181b were involved in sexual reproduction, male gamete generation, and spermatogenesis, and GnRH, Wnt, and MAPK signaling pathway. Four significantly differentially expressed miRNAs and their predicted target genes were validated by quantitative real-time polymerase chain reaction, and phospholipase C beta 1 ( PLCβ1) gene was verified to be a target of ssc-mir-423-5p . Conclusions: This study provides an insight into the functional roles of miRNAs in testis development and spermatogenesis and offers useful resources for understanding differences in sexual function development caused by the change in miRNAs expression between Duroc and Meishan boars.

The discus fish (Symphysodon aequifasciatus) is an ornamental fish that is well-known around the world. Phenotype investigation indicated that there are no significant differences in appearance between males and females of the discus fish. To better understand the sexual development mechanisms and obtain a high efficiency sex identification method in the artificial reproduction process of the discus fish, we constructed six cDNA libraries from three adult testes and three adult ovaries, and perform RNA-sequencing for identifying sex-biased candidate genes, microRNA (miRNA), and metabolic pathway using the Illumina Hiseq 4000. A total of 50,082 non-redundant genes (unigenes) were identified, of which 18,570 unigenes were significantly overexpressed in testes, and 11,182 unigenes were significantly overexpressed in ovaries, and 8 differentially expressed unigenes were validated by quantitative Real-Time PCR (qPCR). A total of 551 miRNAs were identified, of which 47 miRNAs were differentially expressed between testes and ovaries, and 7 differentially expressed miRNAs and one non-differential miRNA were validated by qPCR. Twenty-four of these differentially expressed miRNAs and their 15 predicted target genes constituted 41 important miRNA-mRNA interaction pairs, which may be important candidates for sex-related miRNAs and sex-related genes in the discus fish. Some of vital sex-related metabolic pathways were also identified that may play key roles in regulating gonad development of the discus fish. These results can provide important insights to better understand molecular mechanisms for sexual dimorphism in gonads development.

Abstract The tobacco cutworm, Spodoptera litura, is an important pest of crop and vegetable plants worldwide, and its resistance to insecticides have quickly developed. However, the resistance mechanisms of this pest are still unclear. In this study, the change in mRNA and miRNA profiles in the susceptible, indoxacarb-resistant and field indoxacarb-resistant strains of S. litura were characterized. Nine hundred and ten co-up-regulated and 737 co-down-regulated genes were identified in the resistant strains. Further analysis showed that 126 co-differentially expressed genes (co-DEGs) (cytochrome P450, carboxy/cholinesterase, glutathione S-transferase, ATP-binding cassette transporter, UDP-glucuronosyl transferase, aminopeptidase N, sialin, serine protease and cuticle protein) may play important roles in indoxacarb resistance in S. litura. In addition, a total of 91 known and 52 novel miRNAs were identified, and 10 miRNAs were co-differentially expressed in the resistant strains of S. litura. Furthermore, 10 co-differentially expressed miRNAs (co-DEmiRNAs) had predicted co-DEGs according to the expected miRNA-mRNA negative regulation pattern and 37 indoxacarb resistance-related co-DEGs were predicted to be the target genes. These results not only broadened our understanding of molecular mechanisms of insecticide resistance by revealing complicated profiles, but also provide important clues for further study on the mechanisms of miRNAs involved in indoxacarb resistance in S. litura.

Abstract Background: Hepatocellular carcinoma (HCC) is one of the most malignant tumors in the world. The pathogenesis of HCC is complex and closely related to chronic uncontrollable inflammation. As a bridge between inflammation and cancer, circulating exosomes play a vital role in early tumorigenesis, metastasis, and immune escape. Studies have shown that exosomes containing specific RNAs may be potential diagnostic and therapeutic targets for HCC. Purpose The current research investigated key circRNA through exosome-derived competitive endogenous RNA network based on the ExoRBase database. Methods: The circRNA, lncRNA, and mRNA expression profiles of human blood samples were downloaded from the ExoRBase database. At the standard of P<0.05 and log FC>0, differentially expressed genes (DEGs) were further identified between normal human and HCC patients. The co-expressed pairs of DEGs were predicted by TargetScan, miRcode, and StarBase databases. The ceRNA network was constructed by Cytoscape software. Subsequently, target genes corresponding to circRNA in the ceRNA network were annotated and analyzed by Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genome (KEGG). The potential transcription factors were screened by FunRich database. Results: At the criterion of P<0.05 and log FC>0, 13 differentially expressed circRNAs(DECs) were identified with 9 up-regulated and 4 down-regulated. The co-expressed differentially expressed miRNAs-mRNAs (DEMis-DEMs) (620 pairs), differentially expressed miRNAs- LncRNAs (DEMis-DElncRNA) (684 pairs) and DEMis-DECs (53 pairs) were finally predicted to construct the ceRNA network. The GO analysis indicated that target genes in the ceRNA network were mainly enriched in the molecular function of protein serine/threonine kinase activity. KEGG pathway analysis suggested target genes were enriched in two pathways of MAPK and central carbon metabolism. Conclusion: The study provides a valuable reference for HCC through the ceRNA network in exosomes. Besides, hsa_circ_0000284 may be potential diagnostic markers of HCC.

Abstract The Japanese spineless cuttlefish (Sepiella japonica) is an important economic species and model animal. Many studies suggested that microRNAs (miRNAs) play an important regulatory role in the embryonic development of this species. However, comparative miRNA profiles during embryogenesis of cuttlefish have not been reported before. Therefore, in this study, miRNA profiles were obtained from embryos of S. japonica from eye primordium formation to larval growing stage by miRNA sequencing. A total of 1528 known miRNAs and 203 novel miRNAs were identified during different development stages. Among which, 62 differentially expressed miRNAs among different development stages were identified. GO analysis indicated that the potential target genes for these differentially expressed miRNAs were involved in many GO terms including intracellular membrane-bounded organelle, cell morphogenesis, regulation of developmental process, etc. In addition, miRNA-mRNA network analysis indicated that many of the target genes of these differentially expressed miRNAs were involved in integral component of the membrane. In conclusion, our work provided a global view of miRNA expression profiles during embryonic development of S. japonica.

Purpose. To identify pivotal differentially expressed miRNAs and genes and construct their regulatory network in hepatocellular carcinoma. Methods. mRNA (GSE101728) and microRNA (GSE108724) microarray datasets were obtained from the NCBI Gene Expression Omnibus (GEO) database. Then, we identified the differentially expressed miRNAs and mRNAs. Sequentially, transcription factor enrichment and gene ontology (GO) enrichment analysis for miRNA were performed. Target genes of these differential miRNAs were obtained using packages in R language ( R package multiMiR). After that, downregulated miRNAs were matched with target mRNAs which were upregulated, while upregulated miRNAs were paired with downregulated target mRNA using scripts written in Perl. An miRNA-mRNA network was constructed and visualized in Cytoscape software. For miRNAs in the network, survival analysis was performed. And for genes in the network, we did gene ontology (GO) and KEGG pathway enrichment analysis. Results. A total of 35 miRNAs and 295 mRNAs were involved in the network. These differential genes were enriched in positive regulation of cell-cell adhesion, positive regulation of leukocyte cell-cell adhesion, and so on. Eight differentially expressed miRNAs were found to be associated with the OS of patients with HCC. Among which, miR-425 and miR-324 were upregulated while the other six, including miR-99a, miR-100, miR-125b, miR-145, miR-150, and miR-338, were downregulated. Conclusion. In conclusion, these results can provide a potential research direction for further studies about the mechanisms of how miRNA affects malignant behavior in hepatocellular carcinoma.

Background/Aims: Circulating miRNAs could serve as biomarkers for diagnosis or prognosis of heart diseases and cerebrovascular diseases. Dexmedetomidine has protective effects in various organs. The effects of dexmedetomidine on circulating miRNAs remain unknown. Here, we investigated differentially expressed miRNA and to predict the target genes of the miRNA in patients receiving dexmedetomidine. Methods: The expression levels of circulating miRNAs of 3 patients were determined through high through-put miRNA sequencing technology. Target genes of the identified differentially expressed miRNAs were predicted using TargetScan 7.1 and miRDB v.5. Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to conduct functional annotation and pathway enrichment analysis of target genes respectively. Results: Twelve differentially expressed miRNAs were identified. Five miRNAs were upregulated (hsa-miR-4508, hsa-miR-novel-chr8_87373, hsa-miR-30a-3p, hsa-miR-novel-chr16_26099, hsa-miR-4306) and seven miRNAs (hsa-miR-744-5p, hsa-miR-320a, hsa-miR-novel-chr9_90035, hsa-miR-101-3p, hsa-miR-150-5p, hsa-miR-342-3p, and hsa-miR-140-3p) were downregulated after administration of dexmedetomidine in the subjects. The target genes and pathways related to the differentially expressed miRNAs were predicted and analyzed. Conclusion: The differentially expressed miRNAs may be involved in the mechanisms of action of dexmedetomidine. Specific miRNAs, such as hsa-miR-101-3p, hsa-miR-150-5p and hsa-miR-140-3p, are new potential targets for further functional studies of dexmedetomidine.
