Differential expression profiles analysis of miRNA in granulomatous lobular mastitis

ABSTRACT: Purpose:analysing the differential expression of miRNAs in tissue between GLM patients and healthy controls, provide a comprehensive differential expression profile of miRNAs, screen out possible biomarkers, and elucidate post-transcriptional regulation from the whole level.Methods: The expression profile of miRNAs was measured here by high-throughput sequencing in tissue of GLM patients and healthy controls. Significantly differentially expressed miRNAs were screened by threshold setting and cluster analysis, and their target genes were analysed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment.Results: a total of 31,077 miRNAs were predicted by high-throughput sequencing.Under the condition of threshold ∣log2 fold change (log2FC)|>2.5, qvalue<0.001, 13 miRNAs that were expected to be GLM biomarkers were sreened out. The expression of 13 miRNAs in the GLM group were higher than in the control group, as follows: hsa-miR-106a-5p, hsa-miR-155-5p, hsa-miR-20b-5p, hsa-miR-223-5p, hsa-miR-3916, hsa-miR-4433a-3p, hsa-miR-4433b-5p, hsa-miR-451a, hsa-miR-4659a-3p, hsa-miR-4802-3p, hsa-miR-5571-3p, hsa-miR-624-5p, and hsa-miR-942-3p. Cell and biological process were the most significantly enriched GO term and KEGG pathway.Conclusions: This is the first report detailing genome-wide miRNA profiling of GLM, and the possible targets and pathways of GLM were analysed from bioinformatic analysis. This study finds that 13 significantly differential expressed miRNAs may have important theoretical significance and potential application value and need subsequent large-sample clinical trials for further validation.

Identification of a miRNA panel as a promising biomarker for diagnosis of glioblastoma patients using next-generation RNA sequencing

Project description:Applying Next Generation Sequencing technique we compared the miRNA expression pattern of tumor tissue sample of 6 GPs and peritumoral region of 6 lower grade (I-II) Glioma patients, serving as control group. To determine the difference on miRNA expresion level between GBM and control cases, we performed cluster analysis on the NGS dataset of 6 replicates for each of the two goups of samples with iDEP 96 software. In order to characterize the extent of up- or downregulation, log2FC values were calculated using the iDEP.96 web tool applying the DESeq2 algorithm. On the base of that 117 known miRNAs were identified to be differentially expressed using a threshold of false discovery rate (FDR) <0.05 and fold-change> 2 during the analysis. Among them, 35 miRNAs were upregulated (log2FC > 2) and 82 miRNAs were downregulated (log2FC < -2) with biological revelance in tissue samples comparing with the control samples. To validate our results obtained by NGS, five upregulated miRNAs: hsa-miR-196a-5p, hsa-miR-21-3p, hsa-miR-92b-5p, hsa-miR-10b-3p, hsa-miR-503-5p and three downregulated miRNAs: hsa-mir-383-5p, hsa-mir-490-3p, hsa-mir-1224-3p were chosen for RT-qPCR analysis. As the result of that hsa-miR-196a-5p, hsa-miR-21-3p, and hsa-miR-10b-3p was significantly upregulated while hsa-mir-383-5p and hsa-mir-490-3p was significantly downregulated, compared with those in the control samples. The other three miRNAs: hsa-miR-1224-3p, hsa-miR-92b-5p, hsa-miR-503-5p did not show significant difference between the control group and GPs.

Characterization of microRNAs in spent culture medium associated with human embryo quality and development

Project description:Purpose: Given implantation failure limited the improvement of the in vitro fertilization (IVF) success rate, it was urgent to identify potential biomarkers for embryo quality and predicting the outcomes of IVF-ET. Methods: The expression profiles of 16 spent culture media (SCM) collected from embryos at the cleavage on Day 3 (D3 cleavage) and blastocyst stages on Day 5 (D5 blastocyst) during IVF cycles were determined with RNA-sequencing. Differentially expressed miRNAs (DEmiRNAs) were identified with p-value < 0.05 and |log2FC|> 1. Then, the miRNA-mRNA interaction networks were constructed by using Cytoscape software. Finally, the GO and KEGG pathway analysis of target genes of DEmiRNAs were conducted. Results: Compared with pregnant groups, 29 DEmiRNA were detected in non-pregnant groups at D3 cleavage, and 26 DEmiRNA were detected in non-pregnant group at D5 blastocyst. Among them, a total of six known miRNAs, including hsa-miR-199a-3p>hsa-miR-199b-3p, hsa-miR-199a-5p, hsa-miR-379-5p, hsa-miR-432-5p, hsa-miR-99a-5p and hsa-miR-483-5p, were identified. The results of GO and KEGG pathway analysis indicated that these target genes of DEmiRNAs were associated with various biological processes. Conclusion: In conclusion, we identified three miRNAs, including hsa-miR-199a-5p, hsa-miR-483-5p and hsa-miR-432-5p, may serve as biomarkers for embryo quality during IVF cycles.

Identification of distinct miRNAs associated with SARS-CoV-2 infection

Project description:MicroRNAs (miRNAs) have been shown to play important roles in the pathogenesis of viral infections, but little is known about the miRNA alternations associated with SARS-CoV-2 infection. Here, we performed high throughout sequencing to detect miRNAs in the plasma samples collected from 61 healthy controls, 16 asymptomatic individuals and 100 symptomatic COVID-19 patients. In total, we identified 2,336 known miRNAs and 361 novel miRNAs, including 75 differentially expressed miRNAs with p value<0.05 between various groups. We also found a number of miRNAs that were associated with various clinical presentations and viral persistence of COVID-19, such as hsa-miR-370-3p, hsa-miR-146a-3p, hsa-miR-885-5p, hsa-miR-214-3p and hsa-miR-10b-5p. Further analysis of the target genes, gene ontology and KEGG pathways revealed a panel of miRNAs that were linked to immune responses, viral infections, inflammation and apoptosis. Our findings may help understand the contribution of miRNAs to the pathogenesis of COVID-19 and identify potential biomarkers and molecular targets for the diagnosis and treatment of SARS-CoV-2 infection.

Small RNA-seq analysis of circulating miRNAs to identify phenotypic variability in Friedreich's ataxia patients

Project description:Friedreich’s ataxia (FRDA; OMIM 229300), an autosomal recessive neurodegenerative mitochondrial disease, is the most prevalent hereditary ataxia. In addition, FRDA patients showed additional non-neurological features such as scoliosis, diabetes and cardiac complications. Hypertrophic cardiomyopathy, which is found in two thirds of patients at the time of diagnosis, is the primary cause of death in these patients. In this data set, using small RNA-sequencing of small RNA purified from plasma samples of FRDA patients and controls we identified differential expression of miRNAs (hsa-miR-128-3p, hsa-miR-625-3p, hsa-miR-130b-5p, hsa-miR-151a-5p, hsa-miR-330-3p, hsa-miR-323a-3p, and hsa-miR-142-3p) between both groups. In addition, we found that miR-323a-3p can be used as a biomarker for differentiation of FRDA patients with cardiac problems. Identification of miRNA signatures could therefore provide new molecular explanation for pathological mechanisms occurring during the natural history of the FRDA. Since miRNA levels change with disease progression and pharmacological interventions, miRNAs will contribute to design new therapeutic strategies and improve clinical decisions. Plama miRNA profiles of 25 Friedreich's ataxia patients and 17 healthy subjects were generated by deep sequencing using Illumina HiScan SQ.

Molecular Mechanisms Associated with Primary Open-angle Glaucoma with MicroRNA Microarray Data

Project description:This study aimed to investigate the molecular mechanism responsible for primary open-angle glaucoma (POAG) progression. We analyzed microRNAs (miRNAs) expression profiling in aqueous humor (AH) of both POAG patients and normal controls, using a microarray-based approach. Subsequently, differentially expressed miRNAs (DEmiRNAs) were identified using Bayes moderated t-test. Next, DEmiRNAs target genes were predicted based on miRNA databases, followed by GO analysis and pathway analysis using DAVID. Furthermore, OAG-related genes analysis for target genes was carried out using CTD database, respectively. Finally, verification of DEmiRNAs expression levels was performed by RT-qPCR. A total of 40 significant DEmiRNAs were identified between control and POAG groups, including 24 up-regulated miRNAs and 16 down-regulated miRNAs. Further, the target genes of hsa-miR-206, including BMP2, SMAD4, ID2, and TNF, were mainly enriched in transforming growth factor-β (TGF-β) signaling pathway. While, target genes of hsa-miR-184, hsa-miR-34c-5p, hsa-miR-7-2-3p and hsa-miR-20b-3p, including BCL2, EPHB2, VEGFA, COL4A1, APC, and TGFBR1, were enriched in eye development. Moreover, FNDC3B, CAV2 and VEGF, target genes of hsa-miR-206 or hsa-miR-34c-5p, were the OAG-related genes. Ultimately, RT-qPCR analysis confirmed that mRNA levels of hsa-miR-206, hsa-miR-7-2-3p, and hsa-miR-20b-3p were increased, while those of hsa-miR-184 and hsa-miR-34c-5p were decreased in POAG compared with normal groups (P < 0.05). Hsa-miR-206, hsa-miR-184, hsa-miR-34c-5p, hsa-miR-7-2-3p and hsa-miR-20b-3p might play a significant role in the pathogenesis of POAG and hsa-miR-206 might be associated with the development of POAG by regulating TGF-β signaling pathway. These results might provide insight toward a better understanding of the pathogenesis of POAG.

Identification of miRNAs Related to Osteoporosis by High-throughput Sequencing

Project description:Osteoporosis is a significant health concern, and the role of microRNAs (miRNAs) in cell growth and development regulation is well recognized. High-throughput sequencing technology is widely employed in current research. This study aimed to identify and validate miRNAs associated with osteoporosis. Bone specimens were collected from patients with osteoporosis (n=3) and without osteoporosis (n=3). High-throughput sequencing was utilized to screen for miRNAs, followed by analysis using volcano maps, Wayne maps, gene ontology (GO) analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The identified miRNAs were further confirmed using qRT-PCR. Sequencing analysis revealed 12 down-regulated and five upregulated miRNAs in osteoporosis. GO and KEGG analysis indicated the association of these miRNAs with bone metabolism. qRT-PCR results demonstrated a significant decrease in miR-140-5p, miR-127-3p, miR-199b-5p, miR-181a-5p, miR-181d-5p, and miR-542-3p (all P<0.05) in osteoporosis compared to controls, while miR-486-3p and miR-486-5p exhibited a significant increase (P<0.05). This study utilized high-throughput sequencing to identify differential miRNA expression in individuals with osteoporosis. Specifically, six miRNAs (miR-140-5p, miR-127-3p, miR-199b-5p, miR-181a-5p, miR-181d-5p, and miR-542) showed decreased expression, whereas two miRNAs (miR-486-3p and miR-486-5p) exhibited increased expression. The differential expression of these miRNAs may serve as predictive indicators, potentially aiding in the prognosis and management of osteoporosis.
