Performance Evaluation of Commercial miRNA Expression Array Platforms

ABSTRACT: This data is part of a miRNA platform comparison study. We compared the performance characteristics of four commercial miRNA array technologies and found that all platforms performed well in separate measures of performance. The Ambion and Agilent platforms were more accurate, whereas the Illumina and Exiqon platforms were more specific. Furthermore, the data analysis approach had a large impact on the performance, predominantly by improving precision. Performance of four (4) commercially available miRNA platforms was evaluated using 7 placenta samples spiked with synthetic microRNA spikes (in Latin-square design) absent in placenta. Platforms were primarily evaluated for accuracy and specificity.

Control of oligodendroglial cell number by the miR-17~92 family of miRNA cluster (miRNA Exiqon Part)

Project description:The generation of myelinating cells in the central nervous system (CNS) requires the initiation of specific gene-expression programs in oligodendrocytes. We reasoned that miRNAs could play an important role in this process by regulating critical developmental genes. Microarray profiling of cultured oligodendrocytes identifies the miR-17~92 family of miRNA cluster as highly enriched miRNAs in oligodendrocytes.We specifically deleted the miR-17~92 cluster in oligodendrocytes using the 2Â´3Â´-cyclic nucleotide 3Â´-phosphodiesterase (CNP)-Cre mice. Absence of miR-17~92 leads to a reduction of oligodendrocyte number in vivo and we find that the expression of these miRNAs in primary cultures of oligodendrocytes promotes cell proliferation by influencing Akt signalling. Together, these results suggest that the miRNA pathway is essential in determining oligodendroglial cell number and that the miR-17~92 cluster is crucial in this process. miRNA microarray profiling was used for the identification of miRNAs enriched in oligodendrocytes. Total RNA lysates from primary oligodendroctes compared to primary astrocytes were analysed regarding their miRNA levels. Three independent samples for each of the two cell types were used. The study was initially designed with a comparison of oligodendrocytes, astrocytes and microglia. However, only the comparison of oligodendrocytes and astrocytes is discussed in the present study.

miRQC PGM data

Project description:MicroRNAs are important negative regulators of protein coding gene expression, and have been studied intensively over the last few years. To this purpose, different measurement platforms to determine their RNA abundance levels in biological samples have been developed. In this study, we have systematically compared 12 commercially available microRNA expression platforms by measuring an identical set of 20 standardized positive and negative control samples, including human universal reference RNA, human brain RNA and titrations thereof, human serum samples, and synthetic spikes from homologous microRNA family members. We developed novel quality metrics in order to objectively assess platform performance of very different technologies such as small RNA sequencing, RT-qPCR and (microarray) hybridization. We assessed reproducibility, sensitivity, quantitative performance, and specificity. The results indicate that each method has its strengths and weaknesses, which helps guiding informed selection of a quantitative microRNA gene expression platform in function of particular study goals.

Differential regulation of microRNA in ocular wound healing

Project description:Pterygium is a relatively common human ocular surface fibroproliferative disease that affects vision. Endogenously produced microRNA (miRNA) regulates gene expression in various ocular surface diseases and possibly pterygium. We aimed to investigate the role of miRNA in pterygium. Paired human pterygium and conjunctival tissues were obtained from patients diagnosed with primary pterygium. miRNA microarray profiling identified statistically significant miRNA changes which were matched to reciprocal significant changes in their target transcripts. We employed quantitative real-time polymerase chain reaction and found that hsa-miR-766 was up-regulated (2.57-fold) whilst hsa-miR-215 was down-regulated (0.49-fold) in pterygium compared to conjunctival control. Localization of miRNA was performed using in-situ hybridization. Transcript levels of predicted hsa-miR-766 targets, nuclear receptor subfamily 4, group A, member 1 and epidermal growth factor-containing fibulin-like extracellular matrix protein 1, were down-regulated in pterygium compared to conjunctiva by 0.53- and 0.64-fold, respectively. Collagens type 3, alpha 1 and type 4, alpha 2, both targets of hsa-miR-215, were up-regulated in pterygium by 3.01- and 3.11-fold, respectively. These changes were confirmed in the protein levels using immunofluorescent staining. Derangement of hsa-miR-766 and hsa-miR-215 may cause dysregulation of matrix rearrangement, cell proliferation and adhesion proteins, resulting in pterygium formation. Targeting miRNA may be a possible therapeutic approach in this disease. 3 pterygium samples and 3 matched conjuctiva samples from patients diagnosed with primary pterygium. A pool of all 6 samples was used as the common reference.

Global miRNA transcriptomic profiling of permanent focal ischemia in an in vivo rat model

Project description:Focal ischemia is triggered by the sudden significant reduction of blood supply to the brain, as a result of either the rupture or occlusion by thrombus/embolism of a blood vessel in the brain. Permanent focal ischemia occurred when blood supply to a specific part of the brain is impeded without reperfusion. Despite major steps achieved in the elucidation of the patho-physiology of cerebral ischemia, the available therapeutic avenues for acute ischemic stroke remain scarce. Cell cycle re-activation has been revealed as a novel signaling pathway during permanent focal ischemia. As such, non-specific aurora kinase inhibitor ZM447439, has been injected intracranial-ventricularly 30min post-ischemia induction to determine its efficacy in reduction of neuronal damage in terms of infarct volume. miRNA microarray analysis was performed on Exiqon 5th generation - hsa, mmu & rno (Product no: 208300-A) to compliment our existing gene expression microarray data [GSE23651]. Arrays were run as dual colour (Hy3: Sample, and Hy5: Common sample reference pool). Right cortex RNA samples were collected at two time-points (8h and 24h )respectively for all three experimental conditions: Sham (n=4), vehicle (i.e. ischemic injury with i.c.v. injection 80% DMSO; n=4) and treatment (injury plus i.c.v.injection of 30mM ZM447439 in 80% DMSO; n=4). Supplementary file: Project_Summary_Report.txt The percentages listed in the top row are present-call rates, i.e. number of identified miRNAs compared to number of miRNAs on array.

Identification of XMRV Infection-Associated microRNAs in Four Cell Types in Culture (Experiment B)

Project description:XMRV is a gammaretrovirus that was thought to be associated with prostate cancer (PC) and chronic fatigue syndrome (CFS) in humans until recently. The virus is culturable in various cells of human origin like lymphocytes, NK cells, neuronal cells, and prostate cell lines. MicroRNAs (miRNAs), which regulate gene expression, were so far not identified in cells infected with XMRV in culture. Two prostate cancer cell lines (LNCaP and DU145) and two primary cells (peripheral blood lymphocytes (PBLs) and monocyte-derived macrophages (MDMs)) were infected with XMRV. Total mRNA was extracted from mock- and virus-infected cells at 6, 24 and 48 hours post-infection and evaluated for microRNA profile in a microarray. MicroRNA expression profiles of XMRV-infected continuous prostate cancer cell lines differ from that of virus-infected primary cells (PBLs and MDMs). miR-193a-3p and miRPlus-E1245 were observed to be specific to XMRV infection in all 4 cell types. While miR-193a-3p levels were down-regulated, miRPlus-E1245 on the other hand exhibited varied expression among the 4 cell types. The present study demonstrates that cellular microRNAs are expressed during XMRV infection of human cells. This is the first report demonstrating the regulation of miR193a-3p and miRPlus-E1245 during XMRV infection in four different human cell types. Two prostate cancer cell lines (LNCaP and DU145) and two primary cells (peripheral blood lymphocytes (PBLs) and monocyte-derived macrophages (MDMs)) were infected with XMRV. Total mRNA was extracted from mock- and virus-infected cells at 6, 24 and 48 hours post-infection in duplicates and evaluated for microRNA profile in a microarray. Each test sample RNA was labeled with Hy3 and the reference pool (made by pooling all 24 test samples in each run) was labeled with Hy5.
