Expression data of Sorted CD11b+Gr1+ cells from mice with or without LLC tumor challenging

Project description:We sought to identify genes that are differentially regulated in CD11b+Gr1+ cells after tumor challenging. Mice were challenged with LLC-RFP cells (5×10^6 cells, subcutaneous injection) for 9 days. Single cell suspensions were prepared from lungs of both tumor challenged and control wild type mice and stained with antibodies against CD11b and Gr1. Approximately 1×10^5 CD11b+GR1+ myeloid progenitor cells were sorted by FACS (Aria II, BD Bioscience). Total RNA was extracted from the sorted cells for microarray analysis. In this dataset, we include the expression data of CD11b+Gr1+ cells obtained from both control wild type and tumor challenged mice. These data were used to obtain 22 genes that are upregulated in response to tumor challenging.

Growth factor independence 1 (Gfi1) regulates cell-fate decision of the bipotential granulocytic-monocytic precursor defined by the expression of CD48 as a new marker

Project description:Using bone marrow cells of GFP:Gfi1 knock in mice, we separated Gfi1-high and Gfi1-low expressing cells in the classical CD11b+, GR1-low monocytic cell fraction. We sorted CD11b+, GR1-low GFP:Gfi1-high and low cells as well as CD11b+, GR1-high granulocytes and CD11b-high, GR1-intermediate cells from Gfi1-knock-out mice for further analysis. We used Affymetrix Mouse Genome 430A 2.0 arrays (GPL8321)

Transcription profiling of mouse Gr1- and Gr1+ monocytes

Project description:Six-weeks old (C57Bl6, Cx3cr1gfp/+) mice were intraperitonealy infected with a low number (1.104) of L. monocytogenes (EGDe strain) in exponential growth phase (bacteria were grown in BHI at 108/ml, and diluted 10.000x in PBS immediately before injection). Group of three mice were euthanized, before infection. Peritoneal cells were recovered by peritoneal lavage. Cells from individual mice were stained with antibodies to CD11b (PECy7), Gr1 (APC), NK1.1, B220 and CD3 (PE), and F4/80 (biotin-conjugated followed by streptavidinpacific blue) for sorting. Gr1- monocytes were purified as NK1.1- CD3- B220- CD11b+ F4/80low Gr1-, gfphigh; Gr1+ monocytes were purified as NK1.1- CD3- B220- CD11b+ F4/80low Gr1+, gfpint; and polymorphonuclear cells were purified as NK1.1- CD3- B220- CD11b+ F4/80- Gr1high, gfp-. 1.103 cells from each mice, time point, and phenotype were purified by facs sorting according to their phenotype. Samples were kept at 4°C before and during the sort. Cells were directly sorted in the SuperAmp Lysis Buffer (Miltenyi Biotec, Bergisch Gladbach, Germany) using a FACS Aria cell-sorter (BD biosciences).

Expression data from CD38high vs CD38low CD11b+Gr1+ splenocytes from tumor-bearing L2-Cre;p120f/f mice.

Project description:Myeloid derived suppressor cells (MDSCs) are an immunosuppressive population of immature myeloid cells found in advanced stage cancer patients and mouse tumor models. We have identified Cd38 gene as potentially playing an essential role in MDSC biology. To determine the diffences between CD38high and CD38 low MDSCs from tumor-bearing mice, we have conducted this microarray. In this dataset, we include the expression data obtained from sorted splenic CD38high CD11b+Gr1+ cells from tumor-bearing L2-Cre;p120f/f mice, compared to CD38low CD11b+Gr1+ cells from the same mice. Using these data, we have detected differential expression of 498 genes . The Nos2 gene was among the genes most upregulated in CD38high MDSCs.

Differential expression of Hdc-GFP+/hiCD11b+Gr1+ vs Hdc-GFP-/loCD11b+Gr1+ myeloid cells from mouse bone marrow

Project description:Bone marrow Hdc-GFP+/hi and Hdc-GFP-/loCD11b+Gr1+ cells were isolated from bones from histidine decarboxylase (Hdc) green fluorescent protein (Hdc-GFP) mice Hdc-GFP+/hiCD11b+Gr1+ cells and Hdc-GFP-/loCD11b+Gr1+ cells were sorted by combinations of GFP and myeloid cell surface markers CD11b and Gr1 and their differential mRNA expression compared with Affymetrix microarrays.

Transcription profiling by array of peritoneal macrophages from B6 wild type and B6-Rag1 knock-out mice

Project description:Transcriptional profiling of peritoneal macrophages from B6 (WT) and B6-Rag1KO (Rag1) mice. Peritoneal cells from 40 mice of each genotype were FACS sorted CD11b+MHC-IIhiB220-Gr1- and total RNA extracted with TRI-reagent. Microarray analysis was performed in triplicate with Affymetrix Mouse Gene 1.0 ST chips, following the manufacturer's instructions.
