MicroRNA profiling of different adipose tissues and muscles

ABSTRACT: Purpose: The goals of this study are to compare microRNA profiling in different adipose tissues and muscles using microRNA arrays. Methods: Tissue microRNA profiles of 2-3-month old mice were generated by using miRCURY™ LNA microRNA Array. The samples were hybridized on a hybridization station following the scheme you outlined in the sample submission. Scanning is performed with the Axon GenePix 4000B microarray scanner. GenePix pro V6.0 is used to read the raw intensity of the image. The intensity of green signal is calculated after background subtraction and four Replicated spots of each probe on the same slide have been calculated the median. We use Median Normalization Method to obtain “Normalized Data”, Normalized Data = (Foreground-Background) / median, the median is 50 percent quantile of microRNA intensity which is larger than 50 in all samples after background correction. Results and conclusion: The miRNA expression profiling was completed on our samples. The profiling identified a subset of the total number of miRNAs analyzed by the miRCURY™ array that are differentially expressed in brown adipose tissue, inguinal adipose tissue, epidydimal adipose tissue, gastrocnemius muscle, and soleus muscle.

Circulating miRNAs in serum as biomarkers for early diagnosis of non-small cell lung cancer

Project description:The aim of this study was to explore novel miRNA biomarkers in the serum of lung cancer patients based on miRNA profiling. A miRCURY™ LNA Array was used to identify differentially altered miRNAs in the serum of lung cancer patients (n = 6) and healthy controls (n = 6). Total RNA was isolated using TRI reagent BD (MRCgene, TB-126) according to manufacturer’s instructions. After having passed RNA quantity measurement using the NanoDrop 1000, the samples were labeled using the miRCURY™ Hy3™/Hy5™ Power labeling kit and hybridized on the miRCURY™ LNA Array (v.18.0). Following the washing steps the slides were scanned using the Axon GenePix 4000B microarray scanner.Scanned images were then imported into GenePix Pro 6.0 software (Axon) for grid alignment and data extraction. Replicated miRNAs were averaged and miRNAs that intensities>=30 in all samples were chosen for calculating normalization factor. Expressed data were normalized using the Median normalization. After normalization, significant differentially expressed miRNAs were identified through Volcano Plot filtering. Finally, hierarchical clustering was performed to show distinguishable miRNA expression profiling among samples.

Role of miRNA in inflammatory bowel disease

Project description:This is a miRNA expression analysis by microarray. Comparison was made beween Ulcerative Colitis (UC) vs control, Active UC vs Remission, Ascending Colon vs Rectosigmoid area of Colon. The samples were labeled using the miRCURY LNA™ microRNA Hi-Power Labeling Kit, Hy3™/Hy5™ and hybridized on the miRCURY LNA™ microRNA Array (7th gen) following the scheme you outlined in the sample submission form. The technical data quality assessment showed that the labeling was successful as all capture probes for the control spike-in oligo nucleotides produced signals in the expected range. Following normalization of the quantified signals (background corrected) using the global Lowess regression algorithm, we have performed an unsupervised as well as supervised data analysis.

MicroRNA expression differences in adipose tissue between high and low fat diet mice

Project description:Total RNA was extracted from adipose tissue of high (full) fat diet and standard fat diet mice. Adipose tissue was taken from 16 mice in total. Eight mice were fed a standard diet (SD; control) (10 kcal% fat) and the other eight were fed a high-fat diet (HFD; test) (60 kcal% fat; Research Diets, New Brunswick, NJ) for 5 months. Total RNA was isolated from pooled White Adipose Tissue from SD- or HFD-fed mice using guanidinium thiocyanate. The quality of the total RNA was verified by an Agilent 2100 Bioanalyzer profile. One µg total RNA from sample and reference were labeled with Hy3™ and Hy5™ fluorescent label, respectively, using the miRCURY™ LNA Array power labeling kit (Exiqon, Denmark) following the procedure described by the manufacturer. The Hy3™-labeled samples and the Hy5™-labeled sample were mixed pair-wise and hybridized to the miRCURY™ LNA array version 10.0 (Exiqon, Denmark), which contains capture probes targeting all miRNAs for all species registered in the miRBASE version 11.0 at the Sanger Institute. The hybridization was performed according to the miRCURY™ LNA array manual using a Tecan HS4800 hybridization station (Tecan, Austria). After hybridization the microarray slides were scanned and stored in an ozone free environment (ozone level below 2.0 ppb) in order to prevent potential bleaching of the fluorescent dyes. The miRCURY™ LNA array microarray slides were scanned using the Agilent G2565BA Microarray Scanner System (Agilent Technologies, Inc., USA) and the image analysis was carried out using the ImaGene 8.0 software (BioDiscovery, Inc., USA). The quantified signals were normalized using the global Lowess (LOcally WEighted Scatterplot Smoothing) regression algorithm.

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 response to Snail overexpression in lung cancer cell lines

Project description:Analysis of four lung cancer cell lines transfected with a vector expressing the transcriptional repressor Snail versus a vector control. Aberrant Snail expression is known to induce an EMT program in lung cancers. Four lung cancer cell lines (H292, H358, H441, H1437) with stable overexpression of the human SNAI1 gene and vector expressing controls were collected at equal confluency with the miRNeasy Mini kit (Qiagen). One microgram of total RNA was labeled using miRCURY LNA™ microRNA Array Power Labeling kit by the UCLA Clinical Microarray Core. The labeled miRNAs were hybridized to Exiqon miRCURY LNA microRNA Array-6th Generation according to the manufacturer’s instructions. This array includes 927/648/351 human/mouse/rat miRNAs as well as 438 miRPlus miRNAs. The miRNA array slides were scanned using Axon GenePix 4000B scanner (Axon Instruments, Foster City, CA) and processed by using the GenePix Pro 6.0 software (Axon Instruments). The raw data were normalized by using a combination of housekeeping miRNA, spike-in miRNA and invariant endogenous miRNAs.
