Next Generation Sequencing of miRNA profile in HFD-induced diabetic ICR liver tissue treated by a Chinese formula

ABSTRACT: Objective: To investigate the impact of JTXK granule on the miRNA expression profiles in hepatic tissue of diabetic mice, and to explore the molecular targets and associated signaling pathways of JTXK granule in its anti-diabetic effect. Methods: High fat diet was used to induce diabetic model, and mice were subsequently divided into JTXK-treated group and model group. After 8 weeks’ intervention we screened the differentially expressed miRNAs between the two groups using microRNA sequencing analysis (3 mice in each group). Finally, miRNA target gene prediction, GO and KEGG analysis were applied to explore the function of DEMs. Results: A total of 33 significantly differentiated miRNAs were detected in comparison between the two groups (|log2(fold change) |＞0.3, P<0.05). MiRNA-mRNA analysis showed that mmu-miR-30a-5p, mmu-miR-23b-5p, mmu-miR-199a-5p, mmu-miR-425-5p and mmu-miR-214-3p are closely related to inflammatory response, histological changes and insulin signal transduction in liver. In addition, KEGG analysis showed that the DEMs were closely related to Ras and insulin signaling pathway. Conclusion: JTXK granule exerts anti-diabetic effect in hepatic tissue of diabetic mice by modulating miRNAs and mRNAs network.

Identification of miRNAs as biomarkers of drug response of Pien Tze Huang in Hepatic Fibrosis Treatments

Project description:Pien Tze Huang (PZH) is herbal traditional Chinese medicine which was widely utilized in Asia for hepatic diseases. We constructed two groups hepatic fibrosis mice model using CCl4, one group using PZH treatment and another group replacing PZH with double distilled water. All 12 mice were fed for 8 weeks and then killed to have their liver tissue taken out. Small RNA-seq were used to identify miRNAs of PZH medicine effect for hepatic fibrosis. We found the expression of these miRNAs (mmu-miR-205-5p, mmu-miR-3064-5p, mmu-miR-205-5p, mmu-miR-370-3p, mmu-miR-665-3p) were changed in PZH medicine treatment for hepatic fibrosis study. Furthermore, Hmga2 and Fgf9, miRNAs corresponding target genes (Sp4, Slc2a6, Tln2, Hmga2, Ank3, Pax9, Fgf9), have been reported association with hepatic fibrosis.

Effect of vitrification on the microRNA transcriptome in mouse blastocysts

Project description:Vitrification is commonly used in the cryopreservation of mammalian blastocysts to overcome the temporal and spatial limitations of embryo transfer. Previous studies have shown that the implantation ability of vitrified blastocysts is impaired and that microRNAs (miRNAs) regulate the critical gene for embryo implantation. However, little information is available about the effect of vitrification on the miRNA transcriptome in blastocysts, which partially explains the impaired implantation ability of vitrified blastocysts. In the present study, the miRNA transcriptomes in fresh and vitrified mouse blastocysts were analyzed by microRNA Taqman assay based method, and the results were validated using quantitative real-time PCR (qRT-PCR). Then, the differentially expressed miRNAs were assessed using the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. Overall, 760 known mouse miRNAs were detected in the vitrified and fresh mouse blastocysts. Of these, the expression levels of five miRNAs differed significantly: in the vitrified blastocysts, four miRNAs (mmu-miR-199a-5p, mmu-miR-329-3p, mmu-miR-136-5p and mmu-miR-16-1-3p) were upregulated, and one (mmu-miR-212-3p) was downregulated. The expression levels of all miRNAs measured by the microRNA Taqman assay based method and qRT-PCR were consistent. The four upregulated miRNAs were predicted to regulate 877 candidate target genes, and the downregulated miRNA was predicted to regulate 231 genes. The biological analysis further showed that the differentially expressed miRNAs mainly regulated the implantation of embryos. In conclusion, the results of our study showed that vitrification significantly altered the miRNA transcriptome in mouse blastocysts, which may decrease the implantation potential of vitrified blastocysts.

lncRNA-seq in human lung cancer tissues

Project description:We conducted transcriptome and small RNA sequencing to identify differentially expressed genes (DEGs), miRNAs (DEMs), and lncRNAs (DELs). Function analysis on DEM-target genes can explain the regulatory roles of miRNAs in LC. The lncRNA-miRNA pairs, miRNA-mRNA pairs, and lncRNA-mRNA pairs were identified, which were then combined to construct the interplay of lncRNAs/miRNAs/mRNAs. And we used the online databases to verify the selected DEMs, DELs, and DEGs. Our study identified 2509 DEGs, 34 DEMs, and 432 DELs in LC patients. miRNA-mRNA pairs, including 1 miRNA (hsa-miR-21-5p) and 5 targeted genes (RECK, TIMP3, EHD1, RASGRP1 and ERG), were figured out. We finally found the hub subnetwork (LINC00632/has-miR-21-5p/TIMP3) by combining lncRNA-miRNA pairs, miRNA-mRNA pairs and lncRNA-mRNA pairs.

Genome wide analysis of circulating miRNAs in growth hormone secreting pituitary neuroendocrine tumor patients' plasma

Project description:Objective Circulating plasma miRNAs have been increasingly studied in the field of pituitary neuroendocrine tumor (PitNET) research. Our aim was to discover circulating plasma miRNAs species associated with growth hormone (GH) secreting PitNETs and assess how the plasma levels of discovered miRNA candidates are impacted by SSA therapy and whether there is a difference in their levels between GH secreting PitNETs and other PitNET types. Methods miRNA candidates were discovered using the whole miRNA sequencing approach and differential expression analysis. Selected miRNAs were then analyzed using real-time polymerase chain reaction (qPCR). Results Whole miRNA sequencing discovered a total of 19 differentially expressed miRNAs (DEMs) in GH secreting PitNET patients' plasma 24 hours after surgery and 19 DEMs between GH secreting PitNET patients’ plasma and non-functioning (NF) PitNET patients’ plasma. Seven miRNAs were selected for further testing of which miR-625-5p, miR-503-5p miR-181a-2-3p and miR-130b-3p showed a significant downregulation in plasma after 1 month of SSA treatment. miR-181a-5p and mir-625-5p were also found to be significantly downregulated in plasma of GH secreting PitNET patients vs. NF PitNET patients. Conclusions Our study suggests that expression of plasma miRNAs miR-625-5p, miR-503-5p miR-181a-2-3p and miR-130b-3p in GH secreting PitNETs is affected by SSA treatment. Additionally, miR-625-5p and miR-181a-5p can distinguish GH secreting PitNETs from other PitNET types warranting further research on these miRNAs for treatment efficacy.

Integrated analysis of hepatic miRNA and mRNA expression profiles in the spontaneous recovery of liver fibrosis [mRNA]

Project description:Liver fibrosis, results from the imbalance between extracellular matrix (ECM) production and degradation, is a common pathological consequence of various chronic liver diseases. Although a large number of miRNAs have been reported in liver fibrosis progression, miRNA-mRNA interactions involved in its reversal process remain to be fully elucidated. In the current study, we performed an integrated analysis of miRNA and mRNA expression profiles in a hepatic fibrosis recovery mouse model induced by thioacetamide. A total of 102 miRNA and 2,845 mRNAs showed significant differential expression in recovery mice compared to fibrotic mice. Moreover, 3,769 putative negatively correlated miRNA-mRNA pairs were revealed to be potentially implicated in the biological function regulation of small molecule metabolism and ECM organization. By integrating miRNA-mRNA regulatory networks, mmu-miR-1843a-5p, mmu-miR-193a-5p, mmu-miR-194-2-3p and mmu-miR-30c-2-3p were identified as lysyl oxidase-specific miRNAs that were associated with the pathogenesis of fibrosis recovery. Our results provide potential novel biomarkers and candidate targets for the treatment of liver fibrosis.

Network-based integration of multi-omics data identifies the determinants of miR-491-5p effects

Project description:The identification of miRNAs’ targets and associated regulatory networks might allow the definition of new strategies using drugs whose association might mimic a given miRNA’s effects. Based on this assumption our group devised a multi-omics approach in an attempt to precisely characterize miRNAs’ effects. We combined the analysis of miR-491-5p direct targets, and effects at the transcriptomic and proteomic levels. We thus constructed an interaction network which enlightened highly connected nodes, being either direct or indirect targets of miR-491-5p effects: the already known EGFR and BCL2L1, but also EP300, CTNNB1 and several small-GTPases. By using different combinations of specific inhibitors of these nodes, we could greatly enhance their respective cytotoxicity and mimic miR-491-5p-induced phenotype. Our methodology thus constitutes an interesting strategy to comprehensively study the effects of a given miRNA. Also, we identified targets for which pharmacological inhibitors are already available for a clinical use, or in clinical trial phases. This study might thus enable innovative therapeutic options for ovarian cancer, which remains the first cause of death from gynecological malignancies in developed countries.

Mouse placental microRNA profiling upon zearalenone exposure

Project description:Mycoestrogens are derived from mold and can interfere with female reproduction. Mycoestrogen zearalenone (ZEA) is a common food contaminant in levels of ppb ~ low ppm. Previously we demonstrated disrupted mouse placental development by 40 ppm ZEA diet. MicroRNAs are sensitive to xenobiotics and have been implicated in placental physiology and pathology. We hypothesized that ZEA could dysregulate microRNA expression in the mouse placenta. Gestation day 13.5 (D13.5) placentas from young mice treated with 0 ppm (control), 4 ppm, and 40 ppm ZEA diets were analyzed for microRNA profiling using microRNA array. The top 20 most highly expressed microRNAs in the D13.5 control placentas are predicated to target genes involved in important signaling pathways that are critical for maternal-fetal communications, such as protein processing in endoplasmic reticulum, endocytosis, and regulation of actin cytoskeleton. Using criteria of Log2FC ≥ 1 and Log2FC ≤ -1 (linear 2 fold change (FC)), a false discovery rate adjusted p-value ≤ 0.05, and average reading > 100 (top 20% most abundant microRNAs), R package limma identified 8 differentially expressed miRNAs (mmu-miR-133b-5p, mmu-miR-7028-5p, mmu-miR-294-3p, mmu-miR-3970, mmu-miR-20b-5p, mmu-miR-7683-3p, mmu-miR-291b-3p, mmu-miR-369-3p) in the 40 ppm ZEA group that included all 4 differentially expressed miRNAs in the 4 ppm ZEA group. Some of these differentially expressed microRNAs have been shown in vitro to have important functions in placental growth and maternal-fetal transport. These data imply roles of placental microRNAs in regulating expression of genes critical for placental function in vivo and in sensing environmental contaminants.
