Lost miRNA surveillance of NOTCH, IGFR pathway-road to sarcomagenesis [Illumina]

ABSTRACT: The goal of this study was comparative analysis of differentially expressed miRNA and their targets in human chondrosarcoma JJ012 and chondrocytes C28 cell line(control) to elucidate the major signal transduction pathways deregulation in sarcomagenesis. Total RNA extraction was followed by the analysis of RNA quality and integrity, Exiqon human miRNA panel of 743 unique miRNA assays, Illumina microarray HT12 platform and qRT-PCR verification of targets were performed.189 downregulated and 147 upregulated miRNAs were detected when comparing chondrosarcoma cell line to control C 28 chondrocytes cell line using human Exiqon arrays with biological triplicates.3045 target genes in total were detected woth 587 common and 2458 unique target genes between upand downregulated miRNAs. The upregulated miRNAs were linked to the promotion of aggressive phenotype and the majority of the downregulated miRNAs were oncosuppressors. Among upregulated targtes for upregulated miRNAS were the cluster of cancer testis antigen (CTA) genes, located on X chromosome the major signal transduction pathways leading to sarcomagenesis.

Integrated small RNA, mRNA and protein omics reveal a miRNA network orchestrating metabolic maturation of the developing human heart

Project description:As the fetal heart develops, cardiomyocyte proliferation potential decreases while fatty acid oxidative capacity increases, a highly regulated transition known as cardiac maturation. Small noncoding RNAs, such as microRNAs (miRNAs), contribute to the establishment and control of tissue-specific transcriptional programs. However, small RNA expression dynamics and genome wide miRNA regulatory networks controlling maturation of the human fetal heart remain poorly understood. Transcriptome profiling of small RNAs revealed the temporal expression patterns of miRNA, piRNA, circRNA, snoRNA, snRNA and tRNA in the developing human heart between 8 and 19 weeks of gestation. Our analysis revealed that miRNAs were the most dynamically expressed small RNA species throughout mid-gestation. Cross-referencing differentially expressed miRNAs and mRNAs predicted 6,200 mRNA targets, 2134 of which were upregulated and 4066 downregulated as gestation progresses. Moreover, we found that downregulated targets of upregulated miRNAs predominantly control cell cycle progression, while upregulated targets of downregulated miRNAs are linked to energy sensing and oxidative metabolism. Furthermore, integration of miRNA and mRNA profiles with proteomes and reporter metabolites revealed that proteins encoded in mRNA targets, and their associated metabolites, mediate fatty acid oxidation and are enriched as the heart develops.This study revealed the small RNAome of the maturing human fetal heart. Furthermore, our findings suggest that coordinated activation and repression of miRNA expression throughout mid-gestation is essential to establish a dynamic miRNA-mRNA-protein network that decreases cardiomyocyte proliferation potential while increasing the oxidative capacity of the maturing human fetal heart.

Atrial appendage miRNA-seq in non-, paroxysmal and persistent atrial fibrillation

Project description:MiRNAs regulate posttranscriptional gene expression and are widely implicated in the pathogenesis of complex diseases. We aim to elucidate miRNA regulation of the atrial mRNA signatures that associate with AF. This may provide novel mechanistical insights and candidate targets for therapies using miRNA mimics or antimiRs. We present combined miRNAs-mRNAs sequencing in atrial tissues of patient without AF (n=22), with paroxysmal AF (n=22) and with persistent AF (n=20). MiRNA and mRNA signatures followed an ordinal scale from nonAF to paroxysmal to persistent AF patients. The previously reported mRNA sequencing identified 5228 differentially expressed genes involved in epithelial to mesenchymal transition, endothelial cell proliferation and extracellular matrix remodelling involving collagens, glycoproteins and proteoglycans. We discovered 103 differentially expressed miRNAs. Key downregulated miRNAs included miR-135b-5p, miR-138-5p, miR-200a-3p, miR-200b-3p and miR-31-5p and key upregulated miRNAs were miR-144-3p, miR-15b-3p, miR-182-5p miR-18b-5p, miR-4306 and miR-206. The expression levels of differentially expressed miRNAs were negatively correlated with the expression levels of their predicted target mRNAs. The downregulated miRNAs demonstrated a more profound transcriptome effect than the upregulated miRNAs. Upregulated biological processes enriched in miRNAs targets related to epithelial and endothelial cell migration and glycosaminoglycan biosynthesis, in line with the processes discovered by the mRNA sequencing analysis. Combined analysis of miRNA and mRNA sequencing uncovered miRNAs with a broad transcriptional effect in human AF. Epithelial to mesenchymal transition and endothelial cell proliferation were processes controlled by downregulated miR-135b-5p, miR-138-5p, miR-200a-3p, miR-200b-3p and miR-31-5p, which in turn may contribute to (myo)fibroblast activation and structural remodeling.\

The gene expression profiling among normal chondrocyte, osteoarthritis chondrocyte and chondrosarcoma

Project description:To investigate the gene expression profiling in bone diseases including osteoathritis (OA) and bone cancer (chondrosarcoma), different chondrocytes were isolated and assessed. For OA, the paired normal and OA chondrocytes were isolated from patient with total knee replacement surgery. Identification and delineation of dys-regulated genes between normal and OA chondrocytes and the regulatory mechanisms may provide the opportunity to treat OA. Also, the comparison with normal chondrocyte and chondrosarcoma cell lline (JJ012) gene expression profiling to identify the novel targets for chondrosarcoma therapies.

Differential miRNA expression profiles of primary and relapse lesions of breast cancer patients receiving tamoxifen

Project description:Long-term tamoxifen treatment significantly improves the survival of hormone receptor-positive (HR+) breast cancer (BC) patients. However, tamoxifen resistance remains a big challenge for endocrine therapy. We aimed to identify prognostic biomarkers for tamoxifen treatment and explore their role in tamoxifen resistance. We used Exiqon miRCURY™ LNA Array (v.18.0) to detect the miRNA expression profiles in the primary tumors and their matched recurrent/metastatic lesions from six HR+ breast cancer patients who relapsed after TAM treatment. Fold changes ≥ 2 and P values < 0.05 were defined as differential expression. We found that 28 miRNAs were significantly downregulated in recurrent/metastatic lesions compared to primary tumors, and 54 miRNAs were significantly upregulated.
