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

ABSTRACT: 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.

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.

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.

Real-time quantitative PCR analysis of human plasma miRNA expresson

Project description:Plasma samples from 10 colonrectal cancer patients (CRCs) (including 5 stage II and 5 stage III patients) and 10 normal controls.An amount of 5 to 10 milliliters of whole blood were obtained from each participant.The plasma was obtained by centrifugation at 1200g for 10min at 4°C.To complete the removal of residual cellular components, plasma samples were recentrifuged at 12,000g for a further 10min at 4°C.A volume of 600?L of each plasma samples from CRC group or normal control group was picked out and uniformly mixed. qPCR miRNA expression profiling. Plasma samples form 10 colonrectal cancer patients(CRCs) (including 5 stage II and 5 stage III patients) and 10 normal controls were used and treated as indicated in the summary. Equal amount total RNA from each donor was pooled prior to gene expression analysis.

miRNA profiling in hPASMC isolated from normal and PAH patients

Project description:To identify dysregulated miRNAs in PAH HPASMC, we compared the miRNA expression profiles between normal and PAH HPASMC using the RT2 miRNA PCR Array System. Total RNA was isolated using a miRNeasy Mini Kit (Qiagen, Valencia, CA) and treated with an RNase-Free DNase Set (Qiagen). After quantification with Nanodrop 2000 spectrophotometer (ThermoScientific, Rockford, IL), miRNAs were reversely transcribed using a RT2 miRNA First Strand Kit (SABiosciences, Frederick, MD). The RT2 miRNA PCR Array System (SABiosciences) was used to study miRNA profiling in normal and PAH HPASMC. U6, SNORD44, SNORD47 and SNORD48 were used as internal controls for the profiling. HPASMC isolated from oe normal donor (C128, as control), one IPAH patient (B157), one PAH patient with Eisenmenger’s syndrome (CC-008) and one PAH patient with Scleroderma (CCF-004) were used for miRNA PCR array study. Data is normalized to the control sample. Three independent sample preparations were used for this study.
