Global microRNA profiling of the mouse ventricles during development of severe hypertrophic cardiomyopathy and heart failure

ABSTRACT: The study sought to determine the global miRNA profile of ventricles during early and end-stage hypertrophic cardiomyopathy in a severe double mutant mouse model of the disease. MicroRNA expression profiles of ventricles of transgenic mice with a mutation in both the myosin heavy chain gene (MYH7 Arg403Gln) and cardiac troponin I gene (TNNI3 Ser203Gln) and of non-transgenic mice were determined using Rodent TaqMan Low Density miRNA Arrays A v2.0 (TLDA, Life Technologies). MicroRNA profiles were measured at 10 days of age and 16 days of age, in 3 biological replicates. qRT-PCR analysis of microRNAs of ventricles of three transgenic mice and three non-transgenic mice age 10 days, and three transgenic mice and three non-transgenic mice age 16 days. 450 ng RNA was reverse transcribed, without pre-amplification, using TaqMan MicroRNA Reverse Transcription Kit and Megaplex RT Primers rodent pool A (Life Technologies). Complementary DNA (cDNA) was amplified using a TaqMan rodent microRNA A Array v2.0 (Life Technologies) with TaqMan Universal PCR Master Mix on an ABI 7900HT Sequence Detection System.

miRNA profiling array and analysis in mouse hippocampal neurons

Project description:We addressed the potential for global regulation of miRNA biogenesis by BDNF using miRNA arrays that selectively measure mature miRNA, as opposed to pre-miRNA. Hippocampal neurons were treated with BDNF for 30 min in the presence of Actinomycin-D to assess changes due to processing of existing pre-miRNAs rather than new pre-miRNA production. We used Applied Biosystems 7900HT Fast Real-Time PCR system using Taqman Rodent MicroRNA Array A. Data is from three paired BDNF and Mock experiments (1,2,3). Each array (TaqMan) contained 375 rodent miRNA targets of which 195 were detectable in hippocampus in three independent paired experiments.

MicroRNA expression profiling of skeletal muscle from PPARalpha- and PPARbeta-overexpressing mice

Project description:This experiment was conducted to identify target microRNAs of the peroxisome proliferator-activated receptor (PPAR) in skeletal muscle of transgenic mice that overexpressed PPARalpha or PPARbeta. We have recently demonstrated that skeletal muscle-specific PPARb transgenic (MCK-PPARb) mice exhibit increased exercise endurance, whereas MCK-PPARa mice have reduced exercise performance. Accordingly, we sought to determine whether PPARb and PPARa drive distinct programs involved in muscle fiber type determination. Myosin heavy chain (MHC) immunohistochemical staining of soleus muscle revealed a marked increase in type 1 fibers in the MCK-PPARb muscle compared to non-transgenic (NTG) littermates but a profound reduction in MCK-PPARa muscle. miRNA profiling revealed that levels of miR-208b and miR-499 were increased in MCK-PPARb muscle but reduced in MCK-PPARa muscle. miR-208b and miR-499, which are embedded in the Myh7 and Myh7b genes, respectively, have been shown previously to regulate slow-twitch muscle genes. Lastly, combined inhibition of miR-208b and miR-499 abolished the enhancing effects of PPARb on MHC1 expression in skeletal myotubes, while forced expression of miR-499 in MCK-PPARa muscle completely reversed the type 1 fiber program and exercise capacity. Taken together, these findings demonstrate that miR-208b and miR-499 are necessary to mediate the effects of PPARb and PPARa on muscle fiber type determination. Comparison of microRNA expression from soleus muscles isolated from wild-type (non-transgenic (NTG)) and PPARalpha-overexpressing (MCK-PPARa) mice, and comparison of microRNA expression from soleus muscles isolated from wild-type (NTG) and PPARbeta-overexpressing (MCK-PPARb) mice. Three replicates of each are analyzed.

miRNAs expression in the splenic CD4+ T cells and B cells isolated from MRL/lpr mice at 5 and 16 weeks of age

Project description:To identify any differentially expressed miRNAs in the CD4+ T cells of lupus. MicroRNAs (miRNAs) have been implicated as fine-tuning regulators controlling diverse biological processes at the level of posttranscriptional repression. Dysregulation of miRNAs has been described in various disease states, including human lupus. By using high-throughput microRNA profiling analysis, we identified that two miRNAs (miR-21 and miR-148a) overexpressed in CD4+ T cells from both lupus patients and lupus-prone MRL/lpr mice,which promote cell hypomethylation by repressing DNA methyltransferase 1 (DNMT1) expression. We isolated the splenic CD4+ T cells and B cells from MRL/lpr mice at 5 and 16 weeks of age.Cells were collected and total RNA was extracted for the TaqMan® Low Density Assay v2.0 Normalization was performed with snoRNA202, reference snRNAs for mouse.Comparative real-time PCR was performed in triplicate, including no-template.controls. Relative expression was calculated with the comparative cycle threshold method.

Interaction between ROS and miR-451

Project description:Reactive Oxygen Species (ROS) could be a stress factor that affects microRNA regulation and function in macrophages. The production of microRNAs (miRNA) is influenced by various stimuli, including environmental stresses. We hypothesized that ROS-associated stress could regulate macrophage miRNA synthesis. p47phox-/- mice have deficient NADPH oxidase activity resulting in decreased ROS production. We cultured bone marrow-derived macrophages (BMDM) from wild type (WT) and p47phox-/- mice and profiled miRNA expression using microarrays. The microarray data reveals that there are differences in the expression levels of different miRs, and our studies suggest functional crosstalk between ROS and miR-451 in the regulation of macrophage oxidant stress. Mouse bone marrow-derived macrophages (BMDMs) were obtained from WT (wild type) and p47phox-/- mice. MicroRNAs were isolated by using the mirVana miRNA kit, and a TaqMan rodent microRNA array (consisting of Megaplex RT Primers, Rodent Pool-A, Applied Biosystems) was used for microarray. The array enables quantitation of the expression levels of up to 380 microRNAs and controls. Rodent Pool A contains reverse transcription (RT) primers for 335 and 238 unique microRNAs for mouse and rat, respectively, plus 4 species-specific controls. The data were analyzed on RQ manager software (Qiagen, SA Biosciences) and normalized to the endogenous controls, and analyzed for fold change of miRs in WT compared to p47phox-/-.

MicroRNAs as Regulators of the Immune Response during Allograft Rejection

Project description:MicroRNAs are small non-coding RNA molecules that regulate the post-transcriptional expression of target genes. In addition to being involved in many biologic processes including development, cell differentiation, proliferation, and apoptosis, microRNAs are important regulators in innate and adaptive immune responses. Distinct sets of expressed miRNAs are found in different cell types and tissues and aberrant expression of microRNAs is associated with many disease states. MicroRNA expression was examined in a model of heterotopic heart transplantation by microarray analyses and a unique profile was detected in rejecting allogeneic transplants (BALB/C to C57BL/6) as compared to syngeneic transplants (C57BL/6 to C57BL/6). The microRNA miR-182 was significantly increased in rejecting cardiac allografts and in mononuclear cells that infiltrate the grafts. Forkhead Box (FOX) proteins are a family of important transcription factors and FOXO1 is a target of miR-182. As miR-182 increases after transplant, there is a concomitant post-transcriptional decrease in FOXO1 expression in heart allografts that is localized to both the cardiomyocytes and CD3+ T cells. The microRNA miR-182 is significantly increased in both PBMC and plasma during graft rejection suggesting potential as a biomarker of graft status. Our results identify microRNAs that may regulate alloimmune responses and graft outcomes. In total 14 microRNA microarrays data. For heart graft: each sample column corresponds to the expression profile of 3 pooled syngeneic or 3 pooled allogeneic heart grafts or 3 pooled normal heart. For graft infiltrating lymphocytes (GILs): each sample column corresponds to the expression profile of 3 pooled syngeneic or 3 pooled allogeneic GILs or 3 pooled normal PBMC.

miRNA Profiling in mucosal biopsies of Eosinophilic Esophagitis patients pre and post glucocorticoid steroid treatment

Project description:Eosinophlic esophagitis (EoE) is increasely recognized as an antigen-drived disorder. The goal of this study is to reveal the miRNA expression changes in EoE before and after a successful glucocorticoid steroid treatment. Total RNA was extracted from the esophageal epithelial layers of 5 paired paraffin-embedded biopsies before and after treatment with glucocorticosteroids using RecoverAll Total Nucleic Acid Extraction Kit for FFPE tissues (Ambion, Austin, TX). Five nanograms of total RNA was reverse-transcribed using the Taqman MicroRNA Reverse Transcription Kit and the Megaplex RT primer Human Pool A (Applied Biosystems). The reverse-transcribed cDNA was then pre-amplified in 12 cycles of PCR using Taqman PreAmp Master Mix and the Megaplex PreAmp primers, Human Pool A (Applied Biosystems). The cDNA’s were then diluted and loaded on to a Taqman Human miRNA Array card A (Platform GPL9731 ; Applied Biosystems), which contains probes for 377 distinct miRNAs. The Array cards were run on an ABI HT7900 qPCR instrument. Ct values were obtained for all miRNAs represented on the cards and fold changes in expression were calculated using the delta delta Ct (ddCt) method.
