Re-programming of low-grade inflammatory monocytes

ABSTRACT: Purpose: The goals of this study are to compare the mircoRNA expression profiles from monocytes challegned with subclinical low dosage of LPS Methods: Primary murine bone marrow derived monocytes treated with or without 5 pg/ml LPS in complete culture medium. Harvested mircoRNAs were used to prepare libaray for subsequent sequencing, in triplicate, using HiSeq 1000. Sequences were assayed to ensure high quality for all samples using a custom R script. Reads were first trimmed for adaptor and quality using a combination of custom perl scripts and Btrim64. After trimming, trimmed fastq sequences were imported into mirAnalyzer for mapping, miRNA assembly and prediction, quantitation and differential expression. qRT–PCR validation was performed to validate selected microRNAs. Results: miRNA-seq data confirmed selective induction of a limited set of mircoRNAs in monocytes treated with subclinical super-low dose LPS. Conclusions: Our study revealed that there are selected miroRNAs preferentially induced in monocytes challenged with subclinical low dosage of LPS.

Single cell RNA-seq and machine learning reveal novel subpopulations and regulatory sequences in low-grade inflammatory monocytes

Project description:We report the application of single-cell RNA sequencing(scRNA-seq) in mouse monocyte cells by integrating scRNA-seq, transcriptionfactor binding motifs, and ATAC-seq data using machine learning. We generated scRNA-seqdata from mouse monocytes treated with PBS, SD-LPS, 4-PBA, and SD-LPS + 4-PBA tounderstand the gene regulatory networks of monocytes under the low-grade inflammatorycondition and the mechanism of action for 4-PBA. We find two novelsubpopulations of monocyte cells in response to SD-LPS. We show that 4-PBApotently reprograms an anti-inflammatory monocyte phenotype and masks theeffects of subclinical low dose LPS. Together with TF binding motifs and ATAC-seqdata, a machine learning method, using guided, regularized random forest (GRRF)and feature selection was developed to select the best candidate TFs that areinvolved in the activation of monocytes within different clusters. Our results suggestthat our new machine learning method can select candidate regulatory genes aspotential targets for developing new therapeutics against low-gradeinflammation.

Gene expression changes in Laccaria bicolor mycelium grown under different nutritional conditions

Project description:Illumina technology was used to generate mRNA profiles of Laccaria bicolor mycelium grown under different nutrien conditions. Total RNA was extracted.TruSeq mRNA Stranded libraries were constructed and and sequenced (2 x 150 bp Illumina HiSeq3000) at the Genotoul sequencing facilities (Toulouse, France).

Glycoproteomes of naive and LPS stimulated human monocytes and THP-1 cells

Project description:CD14+ Monocytes from healthy volunteers were purified by MACS (negative selection) and FACSorting and either left untreated or stimulated for 24h and 48h with LPS. THP-1 cells were stimulated for 4h, 24h and 48h with LPS. Glycoproteins were captured with hydrazide chemistry and tryptic and PNGase F-released peptide fractions analyzed by MS/MS. Quantitative assessment revealed differential glycoprotein expression in activated/LPS-tolerized monocytes and naïve monocytes and THP-1 cells.

RNA-seq of chicken spleens after LPS injection

Project description:The acute phase response is poorly studied in chickens, but its examination can possibly supply valuable markers for the identification of subclinical disease and assessment of disease severity. We therefore injected ten six weeks-old Lohmann Selected Leghorn chickens i.v. with 10µg LPS per kg body weight (n=5) or the same volume of PBS as controls (n=5) and collected spleens after three hours. Spleens were kept in ice cold PBS and RNA was isolated immediately. After quality control of RNA (RIN>9.0), a cDNA library was prepared and submitted to Illumina high-throughput sequencing.

RNAseq of haemogenic and aortic endothelium in zebrafish embryos 28-20 hours post fertilization

Project description:The goal of this study is to perform RNAseq in different sub-types of the zebrafish embryonic dorsal aorta (DA) at 28-30 hpf using TgBAC(runx1P2:Citrine);Tg(kdrl:mCherry) double-transgenic zebrafish embryos. A min. of 3000 cells per population were collected via FACS. RNA was isolated with the RNeasy Plus Micro Kit (QIAGEN, Cat No. 74034). High quality RNA (RIN > 8.0) was sent for RNAseq to the Wellcome Trust Centre for Human Genetics (WTCHG). 2.2 ng of total RNA was used to generate SMARTer libraries for low-input RNA. Sequencing was performed on an Illumina HiSeq4000 machine with a 75 bp paired end protocol. Sequenced reads were checked for base qualities, trimmed where 20% of the bases were below quality score 20, and filtered to exclude adapters using Trimmomatic (Version 0.32). Sequences were aligned to the Zebrafish Genome Zv10 with STAR with default parameters. Aligned read features were counted using Subread tool: featureCounts method (version 1.4.5-p1). To determine number of mapped reads we used the trimmed data. The alignment has been performed using STAR with default parameters. The number of mapped reads (QC-passed reads count) has been obtain using Samtools mapping statistics (flagstat tool).

Next Generation Sequencing Facilitates Quantitative Analysis of Transcriptomes in HeLa cells upon Hippo Components Overexpression or Knockout

Project description:Purpose: The goals of this study are to compare and integrate NGS-derived transcriptome when Hippo components are manipulated in HeLa cells. Methods: Total RNAs from three replicates were extracted using TRIzol (Thermo Fisher Scientific) from HeLa cells. RNA quality was assessed using a bioanalyzer (Agilent Technologies). RNA-seq libraries were prepared according to the Illumina TruSeq protocol. Then were pooled for deep sequencing by using Illumina Hiseq Xten (2 × 150) platforms at the Omics Core of Bio-Med Big Data Center, CAS-MPG Partner Institute for Computational Biology, Shanghai, China. Raw read qualities were evaluated with FastQC (http://www.bioinformatics.babraham.ac.uk/projects/fastqc/, v0.11.5). Adaptor sequences and read sequences on both ends with Phred quality scores below 30 were trimmed. Trimmed reads were then mapped with the Hisat2 algorithm (version 2.1.0) to target sequences. Gene expression levels were quantified by the software package HTSeq (v0.6.1p1). The list of differentially expressed genes were generated by DESeq2 with FC：1.5，and adjust p-value<0.05.The significant genes were then compared with each other. Results: We finally get 558 genes that have dramatical change in different groups. Conclusions: Our study shows many common genes that can be loyally regulated by Hippo signaling.
