Project description:Purpose: The study aimed to characterize the molecular phenotype of bone marrow macrophages in NHL with RNA sequencing analysis. Methods:RNA of sorted femur macrophages (CD11b+F4/80+) were extracted with an RNA extraction kit (Qiagen). The samples were submitted to Novogene Inc. for library preparation and subsequent RNA sequencing. RNA was used for cDNA library construction using an NEBNext® Ultra RNA Library Prep Kit for Illumina® (New England Biolabs) according to the manufacturer’s protocol. The resulting 250-350 bp insert libraries were quantified using a Qubit 2.0 fluorometer (Thermo Fisher Scientific) and quantitative PCR. Size distribution was analyzed using an Agilent 2100 Bioanalyzer (Agilent Technologies). Qualified libraries were sequenced on an Illumina HiSeq 4000 Platform (Illumina) using a paired-end 150 run (2×150 bases). Reads containing adapter or poly-N and those of low quality were trimmed, after which gene counts were obtained though mapping the clean reads to reference genome mm10 using STAR 2.5.3a.

Project description:Purpers: To verify the effect of adjuvants (Alhydrogel, AS02, AS03) on immunity of BALB/c mice induced by RSV-F subunit vaccine at the level of gene expression. Methodes:Four groups ((1) RSV-F, (2) RSV-F + Alhydrogel, (3) RSV-F + AS02, and (4) RSV-F + AS03) were analyzed in the transcriptome sequencing experiment. On days 0 and 14, vaccines were administered intramuscularly into the thigh muscle. 14 days after the last vaccination, blood samples from three BALB/c mice in each group were collected. RNA degradation and contamination were assayed. Concentration were measured using a Qubit RNA Assay Kit and a Qubit 2.0 Fluorometer. RNA integrity was assessed using an RNA Nano 6000 Assay Kit and a Bioanalyzer 2100 system. 3 μg RNA per qualified sample was used as input material for RNA library preparation. Sequencing libraries were generated using a NEBNext Ultra RNA Library Prep Kit for Illumina (New England Biolabs, US), and unique index codes were added to each sample. Result: We obtained sample gene expression information. The subsequent differentially expressed gene GO and KEGG enrichment analysis result suggested that AS02 regulates immune balance by activating TLR-4 and promotes Th1-type immune responses.

Project description:Somatic RNA for 40 samples matched to the WGS was extracted using the Qiagen Qiasymphony RNA protcol (cat no 931636). The tissue was initially homogenised using a Qiagen Bioruptor, followed by the manufacturers recommended protocol (including DNase digestion). The resulting RNA the underwent quality control as follows: firstly, A260 and A280nm were measured on a Denovix DS-11 Fx to qualitatively illustrate A260/280nm and A260/230nm ratios as measures of RNA purity. A260/280 had to be 2.0 and A260/230 had to be 2.0-2.2. Then RNA was quantified using LifeTechnologies Qubit RNA BR kit (cat no Q10210). RNAseq was carried out by the Edinburgh Clinical Research Facility on an Illumina NExtSeq500.
Total RNA samples were assessed on the Agilent Bioanalyser (Agilent Technologies, #G2939AA) with the RNA 6000 Nano Kit (#5067-1512) for quality and integrity of total RNA, and then quantified using the Qubit 2.0 Fluorometer (Thermo Fisher Scientific Inc, #Q32866) and the Qubit RNA HS assay kit (#Q32855). Libraries were prepared from total-RNA sample using the NEBNext Ultra 2 Directional RNA library prep kit for Illumina (#E7760S) with the NEBNext rRNA Depletion kit (#E6310) according to the provided protocol. 400ng of totalRNA was then added to the ribosomal RNA (rRNA) depletion reaction using the NEBNext rRNA depletion kit (Human/mouse/rat) (#E6310). This step uses specific probes that bind to the rRNA in order to cleave it. rRNA-depleted RNA was then DNase treated and purified using Agencourt RNAClean XP beads (Beckman Coulter Inc, #66514). RNA was then fragmented using random primers before undergoing first strand and second strand synthesis to create cDNA. cDNA was end repaired before ligation of sequencing adapters, and libraries were enriched by PCR using the NEBNext Multiplex oligos for Illumina set 1 and
2 (#E7500). Final libraries had an average peak size of 271bp. Libraries were quantified by fluorometry using the Qubit dsDNA HS assay and assessed for quality and fragment size using the Agilent Bioanalyser with the DNA HS Kit (#5067-4626). Sequencing was performed using the NextSeq 500/550 High-Output v2 (150 cycle) Kit (# FC- 404-2002) on the NextSeq 550 platform (Illumina Inc, #SY-415-1002). Libraries were combined in an equimolar pool based on the library quantification results and run across 5 High-Output Flow Cell v2.5.

Project description:We report the genome-wide mapping of time-series ChIP-seq data sets of human ERα cell lines (MCF-7). The 4 time points cover 0, 1, 4 and 24 hours, respectively. MCF7 cells were maintained in a hormone-free medium (phenol red–free MEM with 2 mmol/L L-glutamine, 0.1 mmol/L nonessential amino acids, 50 units/mL penicillin, 50 Ag/mL streptomycin, 6 ng/mL insulin, and 10% charcoal-stripped FBS) for three days. MCF7 cells were treated with DMSO (as 0 hour time point) or E2 (108 mol/L) for 1, 4 and 24 hours. 5 x 107 cells were cross-linked with 1% formaldehyde for 10 min, at which point 0.125 M glycine was used to stop the crosslinking. In brief, after crosslinking, cells were treated by lysis buffers and sonicated to fragment the chromatin to a size range of 500bp-1kb. Chromatin fragments were then immunoprecipitated with 10ug of antibody/magnetic beads. The antibodies against ERα were purchased from Santa Cruz Biotechnology (Santa Cruz, sc-8005 X). After immunoprecipitation, washing, and elution, ChIP DNA was purified by phenol:chloroform:isoamyl alcohol and solubilized in 70 μl of water. The ChIP DNA sample was run in 12% PAGE and the 100-300bp DNA fraction was excised and eluted from the gel slice overnight at 4 °C in 300 μl of elution buffer (5:1, LoTE buffer (3 mM Tris-HCl, pH 7.5, 0.2 mM EDTA)-7.5 M ammonium acetate) and was purified using a QIAquick purification kit (Qiagen, Cat#28104). The library was constructed using Illumina genomic DNA prep kit by following its protocol (Illumina, cat# FC-102-1002), clusters were generated on the Illumina cluster station (Illumina, cat# FC-103-1002), DNA samples (20 nM per sample) quantified by an Agilent Bioanalyzer, were loaded onto Illumina Genome Analyzer IIx (GAIIx) for sequencing according to the manufacturer’s protocol. Reads generated from the Illumina GAIIx pipeline were aligned to the Human Genome Assembly (NCBI build 36.1/hg18) using ELAND algorithm.

Project description:Susceptible (CO39 and NPB) and resistant (Pi_gm) rice cultivars were spray inoculated with P. oryzae spore and incubated for 12-hours. Total RNA was extracted from the inoculated rice seedlings (T_Co39, T_NPB, and T_gm) along with their non-inoculated control group C_Co39, C_NPB, and C_gm. The extraction of total RNA from inoculated and non-inoculated control samples was carried-out with RNAprep pure Plant Kit (Tiangen, Beijing) by following processes recommended by the manufacturer. To observe the level of RNA degradation and contamination, the extracted RNA was run on 1% agarose gels. RNA integrity was assessed using the RNA Nano 6000 Assay Kit of the Bioanalyzer 2100 system (Agilent Technologies, CA, USA). RNA concentration was measured with RNA Assay Kit in Qubit 2.0 Fluorometer (Life Technologies, CA, USA). The cDNA library was sequenced on the Illumina sequencing platform (Illumina HiSeq™ 2000) with 150 bp pair-end reads length and 300 bp insert size by Gene Denovo Co. (Guangzhou, China). Novogene in-house Perl script was used to select clean reads by removing adaptor sequences, low quality sequences (reads with more than 50% of bases quality lower than 20) and reads with more than 5% N bases.

Project description:We report the use to RNA-sequencing to understand the role of postnatal Arx in the regulation of PV interneuron function. Total RNA extracted from control and Arx CKO male mice cells were submitted to the Next-Generation Sequencing Core of the University of Pennsylvania for cDNA amplification, library preparation, and sequencing using the Ovation RNA-seq v2 and Rapid DR Multiplexing kits (NuGEN). Whole mRNAseq libraries were prepared from 9 mice (5 control and 4 Arx CKO mice) using the SMARTer Ultra Low RNA Kit for Illumina Sequencing (Clontech, Cat#634936) according to manufacturer’s instructions. Standard methods to assess sample quality (Agilent Bioanalyzer, Kappa Biosystems Library Quantification kit, Qubit® Fluorometer) and measure cDNA concentration were used. A total of 1ng of amplified cDNA for each sample was used as input to build the sequencing libraries. Whole mRNAseq libraries from control and Arx CKO mice were quantified using Agilent Bioanalyzer DNA 7500 chips. Libraries were sequenced on the Illumina HiSeq 4000 2 × 100 (Illumina, San Diego, CA, USA) to generate 150bp paired end reads, yielding approximately 20-40 million reads per sample (~80 million reads per lane).
