Project description:Rationale: Humans encode 12 different IFNa proteins. All of them, except IFNa1 (only binds with IFNAR1), bind with IFNAR1 and IFNAR2 to activate their downstream functions. Currently in the field, it is still a debate whether there are qualitative difference between different IFNa subtypes or the differences are merely quantitative. The current study was set out to elucidate the question. Methods: Commercially purchased PBMCs from 7 donors were mock treated or with ISRE activity normalized IFNa1, IFNa2, IFNa4, IFNa5, IFNa8, IFNa14, or IFNb. RNAs were extracted from cells after 18 hrs of incubation. RNASeq libraries were generated using Lexogen Quant Seq 3’ mRNA-Seq library (FWD) Prep Kit. RNASeq were performed on Illumina NovaSEQ6000. Results: An average of 12.6 million gene counts were identified for each donor/treatment. A total of 50,133 genes were mapped, and among them 333 genes were differentially expressed due to type I interferon treatments. Each of IFNa subtypes or IFNb has their specifically regulated genes in PBMCs. Conclusion: These are the further evidences that there are qualitative differences between type I interferons.

Project description:Purpose: The goal of this study was to analyze the gene expression levels by RNA sequencing from the plantaris muscle of mice exposed to normal air or tobacco smoke for 16 weeks. Methods: Plantaris muscles were removed, flash frozen, and RNA was harvested using the RNeasy Tissue Mini Kit (Qiagen), according to manufacturer’s instructions. RNA was reverse transcribed to complementary DNA (Lexogen QuantSeq 3′ FWD), and sequenced on a HiSeq 4000 instrument (Illumina). Results: Gene clusters representing neurogenesis/axon development, neuronal projection/synapse, and myofibril/sarcomere/muscle differentiation were amongst the most affected by chronic tobacco smoke exposure. In addition, mitochondrial network genes and neuromuscular genes were down-regulated in smoke-exposed mice. Conclusions: Chronic tobacco smoke exposure in mice reprograms the skeletal muscle transcriptome, with a reduction in mitochondrial and neuromuscular junction genes being consistent with mitochondrial respiratory impairment and neuromuscular junction degeneration observed at whole tissue level.

Project description:To assess how LARP6 affects mRNA localisation to cell-protrusions, we transfected MDA-MB231 cells with either non-targeting control siRNA or LARP6 siRNA for 72 hrs, before fractionating the cells into protrusion and cell-bodies, and analysed total RNA from each fraction via Lexogen QUANTSEQ FWD 3' mRNA sequencing. Protrusion induction was done for 2 hrs on 3 micron transwell filters (Corning). The experiment was performed twice using two independent batches of cells, and sequencing was carried out on an Illumina NextSeq 500 sequencer.

Project description:The goal of this study is to use RNA-seq to investigate the molecular mechanisms by which REST inhibition regulates corticalspinal axon regeneration. To achieve this goal, cortical motor neurons from adult wild-type (WT) and REST conditional knockout (cKO) were purified at 1, 3, 7 days following spinal cord injury (SCI) or sham operation. RNA-seq libraries for cortical motor neurons were prepared with the QuantSeq mRNA-Seq library prep kit FWD for Illumina (Lexogen) and sequenced using HiSeq4000 (Illumina). Sequenced reads were mapped to reference genome (mm10) using STAR, and count level data were quantifed using Salmon. Differential gene expression analysis was performed using limma voom.

Project description:Neisseria meningitidis and Borrelia bavariensis are the causative agents of invasive meningococcal disease and Lyme neuroborrelosis. Before infecting the brain parenchyma the bacterial pathogens should cross the human blood-brain barrier (BBB). To understand the response of BBB against the invading pathogens, in vitro BBB spheroid model was generated by co cultivating human brain microvascular endothelial cells, pericytes and astrocytes in low adhesion conditions. Spheroids (N= 36) were infected with either N. meningitidis (6 x 10e4, MOI 1:4) or B bavariensis(1.5 x 10e5, MOI 1:10) for 3h. Two separate control groups of spheroids (N=36) without any infection were included in the study. After 3h of treatment (infection/no infection), 12 spheroids were pooled to form one biological sample and such 3 biological replicates per treatment were sampled for total RNA extraction. Thereafter, 12 cDNA libraries were prepared using QuantSeq FWD 3’mRNA Library Prep Kit (Lexogen). Second strand of cDNA library was synthesized using the UMI Second Strand Synthesis Mix (USS, Lexogen) containing 6 nucleotides long Unique Molecular Identifiers (UMIs). The double stranded cDNA libraries were amplified in 17-19 PCR cycles using i5 Unique Dual Indexing Add-on Kit (Lexogen). Illumina NextSeq 500 was employed to sequence the libraries having a read lengths of single-end 75 bp producing about 10 million reads per library. To carryout gene expression analysis, Bioconductor R-package - DESeq2 v1.20.0 (Love et al., 2014) was used where in, featureCounts tool v1.6.3 (Liao et al., 2013) was used to enumerate the genes. A minimum threshold of adjusted p-value < 0.05 and log2fold-change (log2FC) = ± 1 was set to considered the gene as differentially expressed (DEG).

Project description:Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with localized bone involvement characterized by the presence of bone erosions. Evidence-based data suggest that under inflammatory conditions, classical monocytes are the main source of osteoclasts and might be involved in bone erosion pathophysiology. Here, we analyze the transcriptomic profile of classical monocytes in erosive and non-erosive rheumatoid arthritis patients in order to better understand their contribution to bone erosion. Thirty-nine premenopausal RA patients and 20 healthy age-matched women were recruited for this study. Classical monocytes were isolated from peripheral blood through negative selection. Sequencing library was constructed using the Quant-seq® 30 mRNA-Seq Library Prep Kit (Lexogen®) and sequenced using an Illumina Seq 2500 platform (Illumina®). Differential expression analysis was performed between patients and control groups. Therefore, gene sets analysis was performed to identify the enriched biological pathways. Results suggested that alterations in pathways related to the inflammatory process and impairment of bone formation have an important role in the pathophysiology of bone erosions in patients with rheumatoid arthritis.
