MicroRNA expression profiling of the porcine developing cortex and cerebellum

ABSTRACT: MicroRNA expression profiling using microRNA microarrays was performed on the porcine developing brain. Two tissues, cortex and cerebellum, were sampled at each of three different developmental stages: gestation day 50 (F50), gestation day 100 (F100) and three months old (named adult), respectively. The aim was to find developmental stage-, as well as tissue-specific, microRNA candidates and validate them with qPCR. RNA samples containing the small RNA fraction were subjected to microarray analysis. Three replicates per developmental stage/tissue.

miRNA expression profiling of primary melanoma tumors (cohort II)

Project description:We performed global microRNA expression profiling of a cohort of primary melanoma patient samples linked to a well-annotated clinical database. The goal of this study was to identify microRNA that are associated to or correlated with various clinical parameters and patient outcomes. Candidate microRNA were identified for building prognostic models and functional testing. 119 primary melanoma samples were analyzed in two color arrays. The reference sample used was an equal combination of all samples analyzed. By this design, ratio data of test sample/reference is mean-centered data.

miRNA expression after moderate Spinal Cord Injury in Rats

Project description:Identification of temporal variations in miRNA expression after spinal cord injury caused by thoracic (T8) moderate (200 Kdynes) contusion. Expression changes were analyzed 1, 3 and 7 days after injury and compared to expression of control (untreated) and sham (laminectony but no contusion) individuals. Included groups: control (untreated), 1 day after lesion, 3 days after lesion, 7 days after lesion, 1 days after SHAM cirugy, 3 days after SHAM cirugy, and 7 days after SHAM cirugy. Each of these 7 groups included 5 biological replicates.

Mouse Liver LC-MS/MS LNA miR-676 treated dbdb mice

Project description:Over 40 % of microRNAs are located in introns of coding genes, and many intronic microRNAs are co-regulated with their host genes. In such cases of co-regulation, the products of host genes and their intronic microRNAs can cooperate to coordinately regulate biologically important pathways. Therefore, we screened intronic microRNAs dysregulated in liver of obese mouse models to identify previously uncharacterized coding host genes that may contribute to the pathogenesis of obesity-associated insulin resistance and type 2 diabetes mellitus. Our approach identified that expression of both Ectodysplasin A (Eda), the causal gene of X-linked hypohidrotic ectodermal dysplasia (XLHED; MIM 305100) and its intronic microRNA, miR-676, was strongly increased in liver of obese mouse models. Moreover, hepatic EDA expression is increased in obese human subjects, reduced upon weight loss, and its hepatic expression correlates with systemic insulin resistance. Eda expression in murine liver is controlled via PPARg activation, increases in circulation and promotes JNK activation and inhibitory serine phosphorylation of IRS1 in skeletal muscle. Consistently, bi-directional modulation of hepatic Eda expression in mouse models affects systemic glucose metabolism with alterations of muscle insulin signaling, revealing a novel role of EDA as an obesity-associated hepatokine, which impairs insulin sensitivity in skeletal muscle.

The goal of this study was to identify microRNA that are associated to or correlated with various clinical parameters and patient outcomes. Candidate microRNA were identified for building prognostic models and functional testing. 92 primary melanoma (well-annotated with long clinical follow-up) and 9 congenital nevi samples were analyzed to Exiqon miRCURY two color arrays. The reference sample used was an equal combination of all samples analyzed. By this design, ratio data of test sample/reference is mean-centered data.

miRNA and consolidation of cued fear memory

Project description:miRNA profiling was carried out using the miRCURY LNA™ microRNA Array (6th gen - hsa, mmu & rno) miRNA were profiled in amygdala brain tissue obtained from adult mice 30 mins after auditory fear conditioning and expression levels compared to tissue obtained from Home cage controls Adult male mice were fear conditioned using tone-shock pairings and brains were harvested 30 mins later. The brains of Home Cage controls and Fear Conditioned animals (n = 4/group) were then punched to collect amygdala tissue. miRNA were extracted using the Qiagen miRNeasy Kit, and then shipped to Exiqon. Exiqon performed labeling, hybridization and data analysis after use of the miRCURY LNA™ microRNA Array (6th gen - hsa, mmu & rno). https://www.exiqon.com/ls/Documents/Scientific/miRCURY-LNA-microRNA-Array-6th-gen-hsa-mmu-rno-manual.pdf

microRNA expression profiles in bone marrow fractions from gastric cancer patients

Project description:Both disseminated tumor cells and noncancerous host cells contributed to cancer progression cooperatively in bone marrow. Bone marrow samples were obtained from 4 gastric cancer patients, and were separated into 3 fractions (CD45 positive, CD45 negative/EpCAM positive, and CD14 positive fractions) by the automagnetic-activated cell separation (AutoMACS) system using CD45, EpCAM, and CD14 microbeads (Miltenyi Biotec, Germany). microRNA expression profiles in each fractions were evaluated in order to identify candidate prognostic markers for gastric cancer patients. In 4 patients with gastric cancer, bone marrow samples (40 mL) were obtained from iliac bones. Nucleated cells were collected by gradient centrifugation using Ficoll-Paque PREMIUM (GE Healthcare Life Science, USA) and Leucosep (Greiner Bio-One, Germany) according to the manufacturer’s instructions. Next, we separated bone marrow cells into 3 fractions using MACS: CD45 positive (CD45+), CD45 negative/EpCAM positive (CD45-/EpCAM+), and CD14 positive (CD14+). microRNA expression levels of whole bone marrow cells and each fractions were measured by the miRCURY™ LNA array microarray (6th gen-hsa, mmu & rno#208402, Exiqon, Vedbaek, Denmark). The miRCURY™ LNA array microarray slides were scanned using the Agilent G2505C Microarray Scanner System (Agilent Technologies, Inc., USA) and the data analysis was carried out using the Feature Extraction 10.7.3.1 (Agilent Technologies, Inc., USA).
