Prdm16 newborn mouse (ventricular zone) VZ cells microarray

ABSTRACT: As Prdm16 deficiency reduces self-renewal potential and depletes neural stem cells in culture we decided to investigate the underlying molecular mechanisms of the neural stem cells depletion in the Prdm16 deficient animals. For the experiment we used Prdm16Gt(OST67423)Lex (Prdm16LacZ) genetrap mice obtained from the NIH Mutant Mouse Regional Resource Center (http://www.mmrrc.org/). We compared the gene expression profiles of uncultured ventricular zone cells from newborn Prdm16LacZ/LacZ (KO), Prdm16LacZ/+(HET), and Prdm16+/+ (WT) mice. The uncultured ventricular zone cells from newborn Prdm16LacZ/LacZ, Prdm16LacZ/+, and Prdm16+/+ mice were dissected from the brains and placed into the Trizol reagent. Purified RNA was reverse transcribed and amplified using the WT-Ovation™ Applause WT/Amp RNA amplification system (NuGEN Technologies,) following the manufacturer’s instructions. Sense strand cDNA was fragmented and labeled using the FL-Ovation™ cDNA Biotin Module V2 (NuGEN). 2.5µg of labeled cDNA were hybridized to Affymetrix Mouse Gene ST 1.0 microarrays.

Sox17-transgenic hematopoietic stem cell microarray

Project description:The transcription factor SOX17 is expressed by fetal, but not adult hematoipoietic stem cells (HSCs), and is required for the maintenance of fetal and neonatal, but not adult, HSCs. In the current study we show that ectopic expression of Sox17 in adult HSCs and transiently reconstituting multipotent progenitors was sufficient to confer increased self-renewal potential and the expression of fetal HSC genes including fetal HSC surface markers. To assess the acute effects of ectopic Sox17 expression on global gene expression in adult HSCs, we performed microarray analysis to compare the gene expression profile of adult Sox17-trangenic and control HSCs after short induction of Sox17-transgene expression. Total RNA were isolated from 5 independent, freshly isolated aliquots of 10,000 HSCs isolated from 8-week old Sox17-transgenic ((tetO)7CMVSox17-IRES-NucEGFP;B6.Cg-Gt(ROSA)26Sortm1(rtTA*M2)Jae/J double transgenic) or littermate control mice that were treated with doxycycline for 5 days to induce transgene expression. Purified RNA was reverse transcribed and amplified using the WT-Ovation™ Pico RNA Amplification system (NuGEN Technologies) following the manufacturer’s instructions. Sense strand cDNA was generated using WT-Ovation™ Exon Module (NuGEN), then fragmented and labeled using the FL-Ovation™ cDNA Biotin Module V2 (NuGEN). 2.5µg of labeled cDNA were hybridized to Affymetrix Mouse Gene ST 1.0 microarrays.

Retroviral Sox17 over-expression adult hematopoietic stem/progenitor cells microarray

Project description:The transcription factor SOX17 is expressed by fetal, but not adult hematoipoietic stem cells (HSCs), and is required for the maintenance of fetal and neonatal, but not adult, HSCs. In the current study we show that ectopic expression of Sox17 in adult HSCs and transiently reconstituting multipotent progenitors was sufficient to confer increased self-renewal potential and the expression of fetal HSC genes including fetal HSC surface markers. To assess the mechanisms by which ectopic Sox17 expression in adult hematopoietic progenitors increased self-renewal potential and conferred fetal HSC properties, we compared the gene expression profiles of E16.5 fetal liver HSCs, young adult bone marrow HSCs, young adult bone marrow CD48+LSK cells, and Sox17-expressing CD48+LSK cells isolated from mice that had been transplanted with MSCV-Sox17-infected bone marrow cells 12 weeks earlier. Total RNA (~5ng) was isolated from 3 independent, freshly isolated aliquots of 10,000 E16.5 fetal liver HSCs, 10,000 fetal liver CD48+LSK cells, 10,000 adult bone marrow HSCs, 10,000 adult bone marrow CD48+LSK cells, 10,000 Sox17-expressing CD48+LSK cells isolated from primary recipients 12 weeks after transplantation of MSCV-Sox17-infected bone marrow cells. Purified RNA was reverse transcribed and amplified using the WT-Ovation™ Pico RNA Amplification system (NuGEN Technologies) following the manufacturer’s instructions. Sense strand cDNA was generated using WT-Ovation™ Exon Module (NuGEN), then fragmented and labeled using the FL-Ovation™ cDNA Biotin Module V2 (NuGEN). 2.5µg of labeled cDNA were hybridized to Affymetrix Mouse Gene ST 1.0 microarrays.

Project description:The study is designed to identify transcriptional differences of CD45-Ter119-Cxcl12-DsRed+ stromal cells at different develomental stages. 50,000 CD45-Ter119-Cxcl12-DsRed+ stromal cells from freshly prepared livers of E15.5, P5 and P10 Cxcl12DsRed/+ mice were sorted into Trizol by flow cytometry. Total RNA was isolated and amplified with the WT-Ovation Pico RNA Amplification system (Nugen) as the manufacturer’s instructions. Sense strand complementary DNA was generated using the WT-Ovation Exon Module (Nugen). Then, cDNA was fragmented and labelled using FL-Ovation DNA Biotin Module V2 (Nugen). The labelled cDNA was hybridized to Affymetrix Mouse Gene ST 1.0 chips following the manufacturer's instructions.

Comparison between NuGEN's WT-Ovation Pico and One-Direct Amplification Systems

Project description:Differential gene expression between groups of homogenous cell types is a biological question whose time has come. RNA can be extracted from small numbers of cells, such as those isolated by laser capture microdissection, but the small amounts obtained often require amplification to enable whole genome transcriptome profiling by technologies such as microarray analysis and RNA-seq. Recently, advances in amplification procedures make amplification directly from whole cell lysates possible. The aim of this study was to compare two amplification systems for variations in observed RNA abundance attributable to the amplification procedure for use with small quantities of cells isolated by laser capture microdissection. Arabidopsis root cells undergoing giant cell formation due to nematode infestation and un-infested control root cells were laser captured and used to evaluate 2 amplification systems. One, NuGEN's WT-Ovation Pico amplification system, uses total RNA as starting material while the other, NuGEN's WT-One-Direct Amplification system, uses lysate containing the captured cells. The reproducibility of whole genome transcript profiling and correlations of both systems were investigated after microarray analysis. The NuGEN WT-Ovation One-Direct system was less reproducible and more variable than the NuGEN WT-Ovation Pico system. The NuGEN WT-Ovation Pico Amplification kit resulted in the detection of thousands of genes differentially expressed genes between giant cells and control cells. This is in marked contrast to the relatively few genes detected after amplification with the NuGEN WT-Ovation One-Direct Amplification kit.

FACS Sequencing Analysis of DCX+ cells in the DG of Wild Type and Fmr1-/y; Dcx-DsRed mice

Project description:Purpose: The goals of this study are to investigate the molecular mechanism underlying FMRP-regulated maturation of newborn neurons Methods: DG tissue were isolated from 6-7 weeks old Fmr1-/y; Dcx-DsRed mice and their WT littermates. All cell populations were isolated into single cells using a Becton Dickinson FACS Aria II contained in a Biosafety Carbinet using 20 psi pressure and 100-μm nozzle aperture. 10,000 total alive or Dcx-DsRed+ alive Cells were collected directly in Trizol. Total RNA from the sorted cell was isolated using the Direct-zol™ RNA MiniPrep Kit. Strand-specific, poly(A) selected cDNA libraries were generated using Nugen Ovation® Ultralow Library Systems (Illumina) according to the manufacturer’s protocol. Cluster generation and high-throughput sequencing were performed on a HiSeq 2500 (Illumina), using the paired-end 100 bp protocol. Reads were aligned to the mouse genome GRCm38 with annotation from Gencode. Results: RNA isolated from DsRed+ cells were subjected to next generation sequencing and 519 differentially expressed (DE) genes were identified that showed significant changes (FDR-adjusted P < 0.05) between Fmr1 KO and WT cells.
