Real- time quantiative PCR analysis of HSC derived from sleep deprived mice

ABSTRACT: HSC were derived from mice sleep deprived for 4 hours and compared to mice that slept for 4 hours during the same circadian time. 5 mice were pooled for each sample and bones from femur, tibia and spine were crushed and stained to lineage deplete and enrich for ckit+, sca-1+,Flk-,CD150+, CD34- qpcr miRNA profiling from approximately 50ng total RNA extracted from HSC FACS sorted into Trizol.

Real-time based miRNA array for MCF10 derived cell series with different metastatic potentials

Project description:MCF10AT1 (M-II), MCF10CA1h (M-III) and MCF10CA1a.cl1 (M-IV) are a set of human breast cancer cell lines that derived from the same parent cell line MCF10 but display distinct phenotypes in metastatic potential in the form of xenografts in immune-compromised mice. From M-II to M-IV, the metastatic potential is gradually increased. Using a self-designed real-time PCR based miRNA array containing 242 genes, we tested the miRNA expression levels in these cell lines in order to identify metastasis-related miRNAs. qPCR gene expression profiling. Equal amount total RNA from each cell line was pooled prior to gene expression analysis.

miRNA expression differences between FFPE prostate cancer and adjacent normal tissues using real-time quantitative PCR array analysis

Project description:Laser Capture Microdissected cells from archival FFPE Prostate cancer and normal adjacent tissues from 10 patients (5 CA and 5 AA) were converted to cDNA and analysed by PCR array to identify differentially expressed miRNAs between the groups. Selected differentially expressed miRNAs were further validated in tissues from 40 prostate cancer patients. The miRNAs which were differentially modulated in PCa patients in the validation set were further analysed in 32 urine samples from PCa patients and compared with 12 healthy individuals. Differentially expressed miRNAs were explored to e used as non-invasive biomarker for PCa. qPCR miRNA expression profiling. mRNA from 10 Prostate Cancer patients (5 Caucasian American and 5 African American) and their paired adjacent normal tissue were analysed to identify the differentially expressed miRNA between the groups. Equal amount small RNA from each group was pooled prior to gene expression analysis.

Differential miRNA expression profiling of urinary exosomes from normo- and microalbuminuric type 1 diabetic patients

Project description:The aim of this study was to compare miRNA expression in urinary exosomes from type 1 diabetic patients with and without incipient diabetic nephropathy. Overnight urine collections were obtained from normo- and microalbuminuric type 1 diabetic patients. Urines were pre-cleared by both centrifugation and filtration, urinary exosomes were isolated by two consecutive ultracentrifugation steps and total RNA extracted. Differential miRNA profiling was performed using a Human TaqMan miRNA Array A on an 7900HT Fast Real-Time PCR System. Results showed that expression of 22 urinary exosomal miRNAs differed in incipient diabetic nephropathy. Differential qPCR miRNA profiling was performed on urinary exosomes from 2 pairs of micro/normoalbuminuric type 1 diabetic patients comparable for age, sex, diabetes duration, and tightly matched for HbA1c (1° pair: 8.1 vs. 8.1, 2° pair: 8.7 vs. 8.7). MiRNAs were considered differentially expressed if they exhibited greater than twofold expression differences in both pairs.

miRNA profiling of plasma samples: patients with unstable coronary artery disease and controls

Project description:This study describes a circulating miRNA signature of unstable angina (UA), which may be used as a novel biomarker for unstable coronary artery disease (CAD). The Taqman low-density miRNA array were used to identify distinct miRNA expression profiles in the plasma of patients with typical UA and angiographically documented CAD (UA group, n = 13) compared to individuals with non-cardiac chest pain (control group, n = 13). EDTA-plasma samples were obtained before the cardiac catheterization procedure.The study included 2 groups that were classified according to angiographic evidence and clinical evaluation of chest pain. Patients with chest pain or discomfort but with angiographic exclusion of coronary atherosclerosis were enrolled in the control group (n = 13). Chest discomfort referred to the following complaints: chest pain, pressure, tightness, or heaviness; pain that radiated to the neck, jaw, shoulders, back, or one or both arms; and persistent shortness of breath. Patients with typical unstable angina (UA) and angiographically documented CAD were enrolled in the UA group (n = 13).

Applied Biosystems Human TaqMan Low Density Array (TLDA) in HCC tumor and adjacent non-tumor tissues

Project description:MicroRNAs (miRNAs) are aberrant expressed in hepatocellular carcinoma (HCC) tissue and play a central role in diverse biological processes. We conducted a genome-wide miRNAs screening in 10 pairs of HCC tumor and adjacent non-tumor tissues to test the hypothesis that dysregulation of miRNAs in HCC tumor tissue are partially due to aberrant methylation in relevant miRNAs host genes. Taqman low density arrays were used to examine miRNA profiles in paired HCC tissues, and quantitative RT-PCR was used to validate candidate miRNAs for both discovery and validation sets. A cross-sectional study was conducted in 10 HCC tumor tissues and 10 adjacent non-tumor tissues in Columbia University Medical Center (CUMC), which is approved by the Institutional Review Board.

Differential expression of Hdc-GFP+/hi HSC VS Hdc-GFP-/lo hematopoetic stem cells (HSCs) from bone marrow.

Project description:Bone marrow Hdc-GFPhi and Hdc-GFPlo HSPC (SLAM-LSK, Lin-c-kit+Sca-1+CD150+CD48-) HSCs were isolated from mouse femur and tibia from histidine decarboxylase (Hdc) green fluorescent protein (Hdc-GFP) mice. Hdc-GFPhi HSC and Hdc-GFPlo HSC cells were sorted by combinations of GFP and the cell surface markers of HSC. total RNA was isolated from sorted 2,500 HSPCs using ARCTURUS PicoPure RNA isolation kit (Life Technologies). cDNA was amplified and libraries were constructed by using SMARTer Ultra Low Input RNA kit (Clontech Laboratories) and Nextera XT DNA Library Preparation kit (Illumina) according to manufacturer’s instructions respectively. Sequencing was performed on the Illumina HiSeq2000 platform.

Real-time quantitative PCR analysis of 88 microRNAs involved in human cell differentiation and development in normal fibroblasts stimulated with exogenous TGF-β1 and systemic sclerosis (SSc) dermal fibroblasts

Project description:Normal fibroblasts and SSc fibroblasts between the third and six subpassages were used for experiments. Normal and scleroderma fibroblasts were serum-starved for 24 hours and incubated in the presence or absence of TGF-β1 (2ng/ml) for 6 hours. Total RNA was extracted from culture cells with ISOGEN (Nippon Gene, Tokyo, Japan). MicroRNA isolation from total RNA was performed using RT2 qPCR-Grade miRNA Isolation Kit (SA Bioscience). For RT2 Profiler PCR Array (SABioscience), microRNAs were reverse-transcribed into first strand cDNA using RT2 miRNA First Strand Kit (SABiosciences). A mixture of equal amounts of cDNAs from 5 normal fibroblasts or 5 SSc fibroblasts was prepared. The cDNA was mixed with RT2 SYBR Green/ROX qPCR Master Mix and the mixture was added into a 96-well RT2 miRNA PCR Array (SABiosciences) that included primer pairs for 88 human microRNAs. Human dermal fibroblasts were obtained by skin biopsy from the affected areas (dorsal forearm) of 5 patients with diffuse cutaneous SSc and <2 years of skin thickening. Control fibroblasts were obtained by skin biopsies from 5 healthy donors. Control donors were each matched with a SSc patient for age, sex, and biopsy site.
