Project description:Purpose: Studies in mice have indicated that Tubuloside B has therapeutic potentials in various models of inflammatory diseases. We set out to analyze how Tubuloside B regulates transcription in LPS+IFN-γ-stimulated macrophages. Methods: RNA-seq was performed with two repetitions in RAW264.7 followed by treatment with Tubuloside B and LPS as well as IFN-γ. Conclusions: Tubuloside B inhibits the production of pro-inflammatory cytokines in activated macrophages.

Project description:Setd1bKO primary murine bone marrow-derived macrophages (BMDMs) were treated with lipopolysaccharide (LPS) or dexamethasone and LPS (Dex+LPS) and gene expression differences in response to treatment analysed by PolyA RNA-Sequencing. No Dex-treatment dependent gene expression differences were identified. Setd1aDel/+ Raw264.7 cells with reduced Setd1a expression were analyzed with regards to their reponse to Dex when inflammatorily challenged with LPS by mRNA-Seq. We observed reduced GR-dependent gene acivation in Setd1a hypermorphic Raw264.7 cells. Wild type and Setd1aDel/+ Raw264.7 cells were treated with LPS or LPS and interferon beta (IFNB1) to show the IFNB1-dependent loss of gene expression in LPS-stimulated Setd1aDel/+ cells.

Project description:This study describes the development and validation of the Aquagenomic Sparus aurata oligonucleotide-microarray (SAQ) based on the Agilent Technology system (eArray) to provide a platform for studies on the gene expression of gilthead seabream. The platform developed used all available public ESTs stored and annotated in the Aquagenomic Consortium seabream library (10K). In fish, lipopolysaccharide (LPS) gives a robust cytokine response that is stimulated by crude LPS preparations, some component of the LPS complex are responsible for this stimulation. Peptidoglycan (PGN) is a component of G-negative bacteria (found as a contaminant of crude LPS preparations) able to be recognized by macrophages inducing depth transcriptional modulations and a strong inflammatory response. For microarray analysis, head kidney macrophage cultures were used (N = 36 fish). Each cell culture was stimulated with equal concentrations of PGN and LPS from E. coli O111:B4 strain (10 ug/mL): non-stimulated cell cultures (control n = 9 fish), stimulated during 6 h with LPS (n = 9), and stimulated during 1 h (n = 9), and 6 h (n = 9) with PGN. A loop microarray design approach was used for the study. All experimental RNA samples were labelled with a single colour dye (Cy3) and each stimulated sample was compared to the control sample (pool without stimulation) labelled with the same dye (Cy3). Our microarray analyses identified differential transcriptional modulations in macrophages stimulated with both LPS and PGN at the level of differentially activated RNA transcripts related with the regulation of transcriptional program, prostaglandin synthesis or highlighting the expression of responsive gene-cassettes tightly related to LPS-PGN host recognition.

Project description:(1) We sought to characterize the genomic profiles of H3K18Ac and H3K18Cr before and after the activation of the LPS-induced inflamatory response to elucidate the role of differential acylation in the process of gene activation. We performed chromatin Immunoprecipitation followed by massively parallel sequencing (ChIP-seq) with two antibodies, anti-H3K18Ac and anti-H3K18Cr, in RAW264.7 cells +/- LPS stimulation. (2) We also sought to characterize the effect of increasing the cellular concentration of crotonyl-CoA prior to LPS-stimulation on the expression of different classes of LPS-induced genes. We performed RNA-seq on mRNA isolated from RAW264.7 cells under four conditions a) untreated and unstimulated, b) untreated and LPS stimulated, c) crotonate pre-treated and unstimulated, d) crotonate pre-treated and LPS stimulated. Sequencing was performed on the HiSeq2000 (Illumina).

Project description:Macrophages represent multifunctional leukocytes defined by their stimulus-specific transcriptional reprogramming. As in vivo macrophages are often difficult to obtain, in vitro macrophage models are often used. We aggregated public expression data to define consensus expression profiles for eight commonly-used in vitro macrophage models and built the classifier macIDR, capable of distinguishing macrophage subsets with high accuracy (>0.95). Classification of in vivo macrophages suggested that alveolar macrophages resembled interleukin-10 activated macrophages in general whereas chronic obstructive pulmonary disease patients displayed decreased similarity to interferon-γ stimulated macrophages. Adipose tissue-derived macrophages were classified as unstimulated macrophages, but would resemble LPS-stimulated macrophages more in diabetic-obese patients. Rheumatoid arthritic synovial macrophages were similar to macrophages stimulated with interleukin-10 or interferon-γ. Altogether, our results suggest that macIDR is capable of identifying in vitro macrophages. By projecting in vivo macrophages onto the in vitro macrophages, we were capable of elucidating macrophage-specific changes as a result of tissue and disease.

Project description:Paeony root has long been used for its anti-inflammatory effects. In this study, the effects of albiflorin, paeoniflorin, and paeonol, compounds from paeony root, on gene expression profiles were examined in macrophages. The RAW264.7 macrophages were treated with LPS in the presence or absence of albiflorin, paeoniflorin, or paeonol. Global mRNA expression levels were detected by using an oligonucleotide microarray platform covering the mouse whole genome. Our results demonstrate that paeonol has extensive inhibitory effects on the regulation of inflammation-associated gene expression by LPS in macrophages. In addition, the predominant effect of paeonol among the tested compounds suggests that paeonol may be a major ingredient for the anti-inflammatory effect of paeony root.

A total of 43,398 oligonucleotide probes were used to construct a high-density seabream microarray based on the Agilent 4 × 44 K design format. Microarray hybridization validation was made by analyzing the gene expression profiles in primary cultures of seabream macrophages (MC). 7,285 transcripts with annotated sequences were spotted in triplicate onto the slide (total probes 21,855), as well as 8,377 ESTs without annotation, 183 enriched sequences (gene bank) with 15 replicated probes (total probes 2,745), and finally 1,417 internal control probes of Agilent (N = 43,398).
