Expression data from BNL CL.2 liver cells when cultured with iron, RAW 264.7 macrophages or both

ABSTRACT: We found that co-culturing BNL CL.2 liver cells with RAW 264.7 macrophages increased IRP binding in the first. To further investigate this modulation we investigated the gene expression profile in BNL CL.2 cells cultured alone, with iron, with RAW 264.7 macrophages or in the presence of both iron and macrophages. This novel reconstituted liver cell-macrophage communication pathway with the present gene expression data provides a platform for addressing how macrophages participate in the iron homeostasis of liver cells and, ultimately, in systemic iron homeostasis. We used microarrays to determine the gene expression modulation in BNL CL.2 cells in response to 24h culture with 100 micromolar ferric ammonium citrate (FAC), co-culture with RAW 264.7 macrophages or both

LPS stimulation of Mouse (RAW 264.7) macrophages

Project description:Immunoresponsive gene 1 (IRG1) is one of the highest induced genes in macrophages under pro-inflammatory conditions and its function has been recently described: it codes for immune-responsive gene 1 protein/cis-aconitic acid decarboxylase (IRG1/CAD), an enzyme catalyzing the production of itaconic acid from cis-aconitic acid, a tricarboxylic acid (TCA) cycle intermediate. Itaconic acid possesses specific antimicrobial properties inhibiting isocitrate lyase, the first enzyme of the glyoxylate shunt, an anaplerotic pathway that bypasses the TCA cycle and enables bacteria to survive on limited carbon conditions. To elucidate the mechanisms underlying itaconic acid production through IRG1 induction in macrophages, we examined the transcriptional regulation of IRG1. Using a combination of literature information, transcription factor prediction models and genome-wide expression arrays, we inferred the regulatory network of IRG1 in mouse and human macrophages. 3 unstimulated (Control) and 3 LPS-stimulated RAW 264.7 macrophages

Expression data from chemokine-deficient mus musculus subjected to traumatic brain injury (TBI)

Project description:We inflicted TBI to chemokine-deficient mouse lines in order to establish involvement of various signalling pathways that may be addressed therapeutically. Interacting chemokine pathways in brain regulate distinct inflammatory cells. Activated microglia are separate from invading phagocytes and dendritic cells. Findings show potential targets to interfere with specific inflammatory responses after brain injury. TBI was carried out in Ccl3-/- and Ccr2-/- mice, total RNA prepared from injured cerebral neocortex after three days. RNA samples were from uninjured Ccl3-/- and Ccr2-/- mice as reference for hybridization on Affymetrix microarrays.

Expression data from mus musculus subjected to traumatic brain injury (TBI) for treatment with cyclophosphamide

Project description:We inflicted TBI to wildetype (wt) mice in order to establish whether the anti-inflammatory agent cyclophosphamide can be used therapeutically. Cyclophosphamide was found to regulate distinct inflammatory cells such as activated microglia separate from invading phagocytes and dendritic cells. Cyclophosphamide postinjury selectively reduces antigen-presenting dendritic cells. Findings show feasibility of drug development to interfere with brain inflammation. TBI was carried out in injured wt B6 mice for postinjury treatment with cyclophospamide i.p. using saline as a control substance for comparison with injured but untreated mice. Total RNA was prepared from injured cerebral neocortex after three days. RNA samples were also from uninjured wt mice as reference for hybridization on Affymetrix microarrays.

Environmental factors transmitted by aryl hydrocarbon receptor influence severity of psoriatic skin inflammation [Affymetrix]

Project description:Environmental stimuli are known to contribute to psoriasis pathogenesis and that of other autoimmune diseases, but the mechanism is unknown. Here we show that the aryl hydrocarbon receptor (AhR), a transcription factor that senses environmental stimuli, modulates pathology in psoriasis. AhR-activating ligands reduced inflammation in the lesional skin of psoriasis patients, whereas AhR antagonists upregulated inflammation. Similarly, AhR signaling via the endogenous FICZ ligand reduced the inflammatory response in the imiquimod-induced model of psoriasis and AhR deficient mice exhibited a substantial exacerbation of the disease, compared to AhR sufficient controls. Non-haematopoietic cells, in particular keratinocytes, were responsible for this hyper-inflammatory response, which involved increased reactivity to IL-1beta and upregulation of AP-1 family members of transcription factors. Thus, our data suggest a critical role for AhR in the regulation of inflammatory responses and open the possibility for novel therapeutic strategies in chronic inflammatory disorders. Total RNA obtained from skin explants taken from AhR heterozygous or knock-out mice treated pericutaneously with imiquimod for 0 and 2d.

Regulatory interplay of Cockayne syndrome B ATPase and stress-response gene ATF3 following genotoxic stress

Project description:Gene expression profile in CS1AN deficient and CSBwt restored cell lines after 24 hours of UV or alphe-amanitin treatment (only for restored). The comaprison of expression profile between 0 and 24 hours revealed continouse suppresion of transcription upon UV treatment in CS1AN cell line and alpha-amanitin treated CS1AN CSBwt restored cells. Gene expression profiles were obtained in duplicates for un-treated (assigned as 0h time point) and treated (assigned as 24h time point) cells.

Transcriptome analysis in nutrient deficient wheat roots

Project description:Microarrays were used to identify transcriptional responses in field-grown root material of wheat in order to dissect specific gene expression responses to limited macronutrient availability, particularly phosphate. This study fills the gap between the transcriptome studies on model plants and the lack of studies on soil-grown wheat aiming to identify candidate genes for enhancing nutrient uptake efficiency. The work at Rothamsted Research is supported via the 20:20 Wheat® Programme by the UK Biotechnology and Biological Sciences Research Council. The contribution was supported by BIONUT-ITN and the research leading to these results has received funding from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 264296. T. aestivum cv. Hereward root material was excavated in triplicates in May 2011 at booting stage from sections 0 and 1 plots representing continuous wheat plots of the “Broadbalk” field experiment at Rothamsted Research, UK (http://www.rothamsted.ac.uk/sample-archive/guide-classical-and-other-long-term-experiments-datasets-and-sample-archive). The distinct peculiarity of these plots, including a control plot with nutrient replete wheat plants, is the withdrawal of N, P, K, Mg and S fertilizers exposing the plants to multiple long-term nutrient deficiencies and representing 6 treatments ; 12 samples were analysed.
