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.

The mean values of the groups were used in the analysis. Genes that were upregulated >2 fold were sorted out and generate the table in the Matrix datasheet.

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)

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.

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.
Project description:Purpose: The goals of this study were to identify quantitative gene expression differences between whole tumor and tumor-associated macrophages (TAMs) derived from Lewis lung carcinoma (LLC) tumors grown in wild type and PI3Kinase-gamma-null mice. Methods: mRNA profiles of whole tumor or tumor-associated macrophages (CD11b+Gr1- cells) from wild type (WT) or PI3Kinase-gamma-knockout (p110g-/-) mice were generated by single deep read sequencing, in triplicate or quadruplicate, using Illumina HiSeq 2000. The sequence reads that passed quality filters were aligned to mouse transcriptome using the bowtie2 aligner. Gene-level summaries were normalized and analyzed for differential expression using DESeq.
Project description:Tumors engender an environment dominated by M2 differentiated tumor macrophages that support tumor invasion, metastases and escape from immune control. In this study, we demonstrate that following radiation therapy of tumors in mice there is an influx of tumor macrophages that polarize towards wound repair and immune suppression. To investigate changes in the phenotype of tumor macrophages following radiation therapy, we FACS sorted tumor macrophages from Panc02 tumors. We have previously shown that we can distinguish mature tumor macrophages from immature myeloid and MDSC populations by expression of Gr1 and IA (MHC class II). To isolate these sub-populations, we first gated CD11b+ cells in the untreated or irradiated tumors, then sorted the CD11b+IA+ macrophage population and the CD11b+Gr1hi MDSC population. Cytospins of the sorted populations demonstrates that the CD11b+Gr1hi MDSC predominantly have a granulocyte morphology and the CD11b+IA+ cells have a macrophage morphology in both the untreated and irradiated tumors. RNA was purified from CD11b+IA+ macrophages from untreated or irradiated tumors 1 day or 7 days following radiation therapy and Gene Expression Microarray analysis was performed.
