RNA sequencing of microglia sorted form tamoxifen treated Sall1CreER/fl and control Sall1fl/fl mice

Project description:Microglia are the resident macrophages of the central nervous system (CNS). Gene profiling identified the transcriptional regulator Sall1 as a microglia signature gene. Given the high expression of Sall1 in microglia, we sought to identify its function in vivo. The Sall1CreER allele has been targeted into the Sall1 locus, therefore Sall1CreER/fl mice (heterozygous for both alleles) allow inducible ablation of Sall1 expression in microglia after tamoxifen treatment. We performed RNA-seq to examine gene expression profiles of microglia sorted from tamoxifen treated adult Sall1CreER/fl mice and Sall1fl/fl control littermates. Microglia were obtained with > 98% purity and the absence of Sall1 was confirmed in Sall1CreER/fl microglia. We could show that deletion of Sall1 in microglia in vivo resulted in the conversion of these cells from resting tissue macrophages into inflammatory phagocytes leading to altered neurogenesis and disturbed tissue homeostasis. Similar changes in gene expression profiles were found in Sall1-deficient microglia isolated from tamoxifen-treated Cx3cr1CreERSall1fl/fl mice. In these mice, deletion of Sall1 is targeted to CX3CR1+ myeloid cells including microglia and CNS-associated macrophages but not to any other CNS-resident cells. This indicated that Sall1 transcriptional regulation maintains microglia identity and physiological properties in the CNS.

Expression data from murine skin of tamoxifen-induced Ugcgfl/fl K14CreERT2 vs. Ugcgfl/fl

Project description:Tamoxifen-induced deletion of endogenous GlcCer-synthesizing enzyme UDP-glucose:ceramide glucosyltransferase (UGCG) in keratin K14-positive cells results in epidermal GlcCer depletion. We used microarrays to investigate the molecular consequences of Ugcg-depleted mouse epidermis. Ugcgfl/fl K14CreERT2 vs. Ugcgfl/fl samples taken at day 21 post tamoxifen induction

RNAseq Iron-Treated iPSC-derived Microglia

Project description:Iron accumulation in microglia has been observed in AlzheimerÃ¢Â€Â™s disease and other neurodegenerative disorders and is thought to contribute to disease progression through various mechanisms including neuroinflammation. To study the interaction between iron accumulation and inflammation, we treated human induced pluripotent stem cell-derived microglia (iPSC-MG) with an increasing concentration of iron, in combination with inflammatory stimuli such as interferon gamma and amyloid ÃŽÂ², and performed RNA sequencing.

Naïve and LCMV Cl13 infected liver tissue of ERT2 AlbCre Ifnar1 fl/fl mice

Project description:Age- and sex-matched (male, 2-3 months old) ERT2 AlbCre Ifnar fl/fl and ERT2 AlbCre Ifnar +/+ mice were injected intraperitoneally with 40 mg/kg tamoxifen for 5 consective days. Mice were then intravenously infected with 2x10^6 focus forming units of LCMV Cl13 and liver tissue of either genotype was harvested 1.5 days post infection and analyzed for transcriptomic changes (n = 3). Liver tissue of uninfected animals of both genotypes was harvested as control (n = 3).

RNAseq of cell line from pancreas from KRasG12D/RosaMycER mouse treated with Tamoxifen

Project description:Experiment designed to study the effect of deregulated myc on pancreatic cancer progression and regression. In the KRasG12D/RosaMycER mouse model KRas and MycER are expressed exclusively in the pancreas, but MycER activity depends on Tamoxifen presence. For this experiment a mouse was treated with Tamoxifen during 3 weeks, the pancreas was collected and the epithelial cells were grown in vitro in the presence of 4-OHT (4-Hydroxytamoxifen, active form of Tamoxifen). RNAseq were preformed on the cell line treated as follows: 1- 4-OHT all the time. 2- EtOH 6h. 3- EtOH 12h. 4- EtOH 18h.

Decoupling astrocytes in adult mice impairs synaptic plasticity and spatial learning

Project description:To study the role of the gap junction coupled astrocytic network, we generated inducible double knockouts to selectively delete Cx30 and Cx43 from astrocytes in adult mice. Mice carrying loxP-flanked Gjb6 (Cx30fl/fl mice) (Boulay et al., 2013) and Gja1 (Cx43fl/fl mice) (Theis et al., 2003) alleles were crossbred with mice expressing the tamoxifen-sensitive Cre-recombinase CreERT2 under the endogenous GLAST(Slc1a3)-promoter (Mori et al., 2006). Adult, 8-10 week old mice (Cx30fl/fl:Cx43fl/fl:GLASTCreERT2/+, termed cKO) and littermate control mice (Cx30fl/fl:Cx43fl/fl:GLAST+/+) were injected with tamoxifen for 5 consecutive days and hippocampi were isolated for subsequent TMT-based proteomics analysis 90 days after tamoxifen treatment, to study the consequences of astrocyte decoupling and connexin deletion.
