Project description:RNA samples were prepared from freshly sorted mammary cell subpopulations (MaSC/basal-enriched, luminal progenitor, mature luminal and stromal) from five sets of adult mice. High throughput RT-PCR was used to measure the global microRNA expression profiles of each cell subpopulation. The expression profiles were compared between cell subpopulations to gain insight into the regulation of lineage-restricted genes. High throughput RT-PCR profiling of microRNA expression in four mouse mammary cell populations. Samples were collected from pooled mammary gland tissue from a number of mice. Samples were collected at over five different times with tissue from independent sets of mice.
Project description: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.
Project description:This study sought to determine the dynamic changes of miRNA expression during mouse granulopoiesis. We not only performed analyses of miRNA expression levels in whole cells but also analyzed purified nuclear and cytoplasmic cell fractions to profile miRNA subcellular localization. qRT-PCR analysis of miRNAs was performed on whole cell, nuclear and cytoplasmic RNAs extracted from mouse hemopoietic stem cells (LSKs), promyelocytes, myelocytes and granulocytes. 100 ng of RNA was reversed transcribed using the Taqman miRNA Reverse Transcription Kit and Megaplex RT Primers rodent pool A and B (Life Technologies). Complementary DNA (cDNA) was amplified using a TaqMan rodent microRNA A and B Array v2.0 (Life Technologies) with TaqMan Universal PCR Master Mix on an ABI 7900HT Sequence Detection System.

Project description:By use of large-scale miRNA expression profiling we identified microRNAs with significantly different expressions in epithelial-mesenchymal transition (EMT)-positive tumors and selected microRNAs for training phase of the study to evaluate their diagnostic and prognostic potential. Further, microRNAs were forwarded to validation phase, where all evaluated microRNA candidates were confirmed to be significantly deregulated in tumor tissue, some of them significantly differed in metastatic tumors, correlated with clinical stage, with Fuhrman grade and with overall survival.
Project description:We characterised and compared the microRNA profiles of the hippocampus tissues from experimental and control groups. The rats in experimental group were exposed to flurothyl and presented recurrent seizure phenotype. The control group were exposed to solvent. There are three tissue samples in each group. 2 out of 3 samples in each group has raw data. 1 out of 3 samples in each group has exported txt file data from the raw data due to technical issues.
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-/-.
Project description:ANGPTL1-overexpressed CL1-5 cells were used to identify miRNAs which regulate EMT, cancer invasion and metastasis. We used microRNA Taqman Low Density Array to identify candidate miRNAs ANGPTL1-overexpressed CL1-5 cells were analyzed compare to vector control (pcDNA3.1) CL1-5 cells
Project description:We performed miRNA and mRNA profiling at postnatal day 14 and day 29 to compare hyperoxia-induced bronchopulmonary dysplasia and wild type. We built potential miRNA-mRNA interaction networks specific to brochopulmonary dysplasia. Replicated time course of mouse lung development at 2 time points (P14, P29). Three replicates per time point for bronchopulmonary dysplasia induced by hyperoxia mouse lung, and two replicates per time point for wild type mouse lung. This dataset represents the miRNA profiling component of the study.
