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. 8 total samples were analyzed: 3 pairs of CD38high and CD38 low MDSCs (coming from individual mice), as well a pair of CD38high and CD38low pulled MSDCs (splenocytes from 3 mice were pulled together for sorting to increase yields). Gene expression difference was determined by univariate test (two-sample t-test) with multivariate permutation test (10,000 random permutations). A cut-off p-value of less than 0.001 and minimum 2-fold expression change were used to identify genes with significant expression differences between the two groups.

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. To identify potential genes playing essential role in MDSC biology, we have conducted microarray analysis of gene expression in MDSCs from esophageal tumor-bearing mice, compared to immature myeloid cells from healthy littermate control mice. In this dataset, we include the expression data obtained from sorted splenic CD11b+Gr1+ cells from tumor-bearing L2-Cre;p120f/f mice, compared to healthy littermate controls. Using these data, we have identified 964 genes showing differential expression between the two groups. Among these was the Cd38 gene, which was among the genes most upregulated in MDSCs from tumor-bearing mice.

Among these was the Cd38 gene, which was among the genes most upregulated in MDSCs from tumor-bearing mice. 9 total samples were analyzed: 6 sample from experimental tumor-bearing mice and three pooled samples from control mice. Gene expression difference was determined by univariate test (two-sample t-test) with multivariate permutation test (10,000 random permutations). A cut-off p-value of less than 0.001 and minimum 2-fold expression change were used to identify genes with significant expression differences between the two groups.

Project description:While angiogenesis inhibitors have provided significant clinical benefit as cancer therapeutics, the mechanisms of anti-VEGF resistance remain incompletely understood. We uncovered an interleukin-17 mediated paracrine network of signaling between the adaptive and innate immune system associated with resistance to anti-VEGF treatment in multiple tumor models. The expression of tumor-associated fibroblasts and tumor-associated granulocytes (defined as CD11b+Gr1+) and tumor-associated monocytic cells (defined as CD11b+Gr1-) were compared between wildtype and IL-17RC knockout tumor bearing mice.

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.
