Respiratory syncytial virus (RSV) F subunit vaccine with adjuvants affect immunity in BALB/c mice

ABSTRACT: 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.

Postnatal loss of Arx transcriptional activity in parvalbumin interneurons induces epilepsy-like network abnormalities

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).

RNA sequencing in human iPSCs derived from bipolar patients to identify important therapeutic molecular targets of Valproate(VPA)

Project description:Valproate(VPA) has been used in the treatment of bipolar disorder since the 1990s. However, the therapeutic targetsof VPA have remained elusive. Here we used RNA sequencing in human iPSCs derived from bipolar patients to further identify important molecular targets. Human iPSCs were homogenized and total RNA was isolated using the RNeasy Plus Micro Kit (Qiagen, Hilden, Germany). RNA quantity and quality were assessed using fluorometry (Qubit RNA Broad Range Assay Kit and Fluorometer; Invitrogen, Carlsbad, CA) and chromatography (Bioanalyzer and RNA 6000 Nano Kit; Agilent, Santa Clara, CA), respectively. Libraries were prepared using TruSeq Stranded mRNA (PolyA+) kit (Illumina, San Diego, CA) and sequenced by Illumina NextSeq 500. The read length was 75bp with 30-40M reads per sample. FastQC (v0.11.3) was performed to assess data quality. TopHat2 (v2.0.9) aligned the reads to the mouse reference genome (Mus musculus UCSC mm10) and to the Ensembl human reference genome (GRCh38.p13) using default parameters. Alignments were then converted to expression count data using HTseq (v0.6.1) with default union mode.

Identification of quiescent and spatially-restricted mammary stem cells that are hormone responsive

Project description:Purpose: The aim of this study is to explore histone modification in four basal cell populations defined by Lgr5 and Tspan8 expression taken from adult mouse mammary glands using chromatin immunoprecipitation sequencing (ChIP-seq). Methods: The ChIP DNA samples were prepared and indexed for Ilumina sequencing using the TruSeq DNA sample Prep Kit (Ilumina) as per manufacturer's instruction. The library was quantified using the Agilent Tapestation and the Qubit's RNA assay kit for Qubit 2.0 Fluorometer (Life Technologies). The indexed libraries were then prepared for paired-end 75bp sequencing on a NextSeq500 instrument using the 150 cycle kit v2 chemistry (Ilumina) as per manufacturer's instructions. Reads were aligned to the mouse genome (mm10) using the subread algorithm by Liao et al. (2013) and counted into bins associated with Entrez gene identifiers (27080 genes in total) using featureCounts in two different ways. Genebody counts summarised the number of reads overlapping anywhere between the first and last base of a given gene while promoter counts summarized the number of reads overlapping a region 3000 bases upstream to 2000 bases downstream of the TSS of each gene. For downstream analysis, genebody counts were used for the H3K27me3 marks and promoter counts were used for the H3K4me3 marks.

Bayogenin 3-O-Cellobioside is a novel anti-blast metabolite produced in rice in response to Pyricularia oryzae infection

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:Ovarian cancer is the deadliest gynecologic malignancy and the fifth leading cause for cancer related deaths among women in USA. For a comprehensive understanding of the gene expression changes accompanying ovarian carcinogenesis, we isolated RNA from 8 pairs of matched FT and primary tumors from OC patients and sequenced them. Library preparation and next generation RNA sequencing was carried out at the Center for Genomics and Bioinformatics core facility, Indiana University, Bloomington.

snRNA-seq of whole hearts from adult fzt:DU mice

Project description:We used snRNA-seq to investigate for the first time an entire adult mammalian heart. To avoid potential aberrations due to inbreeding, we relied on an outbred mice strain (Fzt:DU) (Dietl, G.; Langhammer, M.; Renne, U. Model simulations for genetic random drift in the outbred strain Fzt:DU. Arch. Anim. Breed. 2004, 47, 595–604). Whole hearts were harvested from 4 male mice (12 weeks) after cervical dislocation. The hearts were pooled and nuclei isolated using the Nuclei PURE Prep isolation kit (Sigma-Aldrich, Darmstadt, Germany) according to the manufacturer’s protocol. Sequencing was conducted by Genewiz (Leipzig, Germany) on the 10xGenomics system. Single nuclei were captured in droplet emulsions and snRNA-seq libraries were constructed as per the 10x Genomics protocol using GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. RNA was controlled for sufficient quality on an Agilent 2100 Bioanalyzer system and quantified using a Qubit Fluorometer. For further experimental details as well as computational scripts and results can be obtained from http://doi.org/10.15490/FAIRDOMHUB.1.STUDY.713.1.
