Databases pertaining to various diseases provide valuable resources on particular genes of interest but lack the molecular subtype and epithelial-mesenchymal transition status. CSIOVDB is a transcriptomic microarray database of 3,431 human ovarian cancers, including carcinoma of the ovary, fallopian tube, and peritoneum, and metastasis to the ovary. The database also comprises stroma and ovarian surface epithelium from normal ovary tissue, as well as over 400 early-stage ovarian cancers. This un ...[more]

Gene expression profiling in cumulus cells (CC) derived from a modified natural and stimulated in vitro fertilization (IVF) procedures

Project description:Cumulus cells surrounding mature oocytes that developed to moruale/blastocyst stage on day 5 of IVF cycle were collected and used for gene expression profiling using Affymetrix Human Gene 1.0 ST Arrays in order to determine differences in gene expression between the modified natural and stimulated in vitro fertilization (IVF) procedures. Microarray analysis was made on 8 individual CC samples, derived from 5 patients that first underwent MNIVF, followed by a controlled ovarian hyperstimulation (COH) cycle. As the quality of the isolated RNA derived from 2 of the MNIVF CC samples was not good, these samples were not included in the analysis. Altogether, 3 CC samples from MNIVF and 5 CC samples from COH cycles were included in microarray analysis.

The cellular origin and malignant transformation of Waldenström's Macroglobulinemia [gene expression]

Project description:Although information on the molecular pathogenesis of Waldenström’s Macroglobulinemia (WM) has greatly improved in recent years, the exact cellular origin and the mechanisms behind WM transformation from IgM MGUS remain undetermined. Here, we undertook an integrative phenotypic, molecular and genomic approach to study clonal B-cells from newly-diagnosed patients with IgM MGUS (n=22), smoldering (n=17), and symptomatic WM (n=10). Through principal-component-analysis of multidimensional flow cytometry data, we demonstrated overlapping phenotypic profiles between clonal B-cells from IgM MGUS, smoldering and symptomatic WM patients. Similarly, virtually no genes were significantly deregulated between FACS-sorted clonal B-cells from the three disease stages. Interestingly, while the transcriptome of the Waldenström’s clone was highly deregulated as compared to CD25-CD22+ normal B-cells, significantly less genes were differentially expressed and specific WM pathways down-regulated while comparing the transcriptome of the Waldenström’s clone vs. its normal phenotypic counterpart: CD25+CD22+dim B-cells. The frequency of specific copy number abnormalities [+4, del(6q23.3-6q25.3), +12, and +18q11-18q23] progressively increased from IgM MGUS and smoldering WM vs. symptomatic WM (18% vs. 20% and 73%, respectively; P =.008), suggesting a multistep transformation of clonal B-cells that albeit benign (i.e.: IgM MGUS and smoldering WM), already harbor the phenotypic and molecular signatures of the malignant Waldenström’s clone.

Expression data measured by microarray of CD4+ T cells from healthy individuals stimulated with anti-CD3/CD28 with or without IFNb or Th17 polarizing cytokines

Project description:Variation in individuals' adaptive immune response is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and activated CD4+ T cells derived from the peripheral blood of healthy individuals. We activated the primary T cells with anti-CD3/CD28 beads. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and negatively selected for CD4+ T cells using RosettaSep. We then either left cells unstimulated or stimulated them with beads conjugated with anti-CD3 and anti-CD28. Cells from 15 individuals were harvested at up to 3 time points (0hr, 4hr or 48hr), lysed and RNA isolated to be profiled on microarray.

Time course expression measured by microarray of fresh CD4+ response to activation from healthy individuals

Project description:Variation in individuals' adaptive immune response is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and activated CD4+ T cells derived from the peripheral blood of healthy individuals. We activated the primary T cells with anti-CD3/CD28 beads alone or with IFNb or Th17 polarizing cytokines. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and negatively selected for CD4+ T cells using RosettaSep. We then either left cells unstimulated or stimulated them with beads conjugated with anti-CD3 and anti-CD28 either without additional cytokines, or with IFNb, or with Th17 cocktail. Cells were harvest at up to 8 time points (0hr, 45min, 2hr, 4hr, 10hr, 24hr, 48hr and 72hr), lysed and RNA isolated to be profiled on microarray.

Expression data from five primary human glioblastomas (frozen surgical resection) and one non-neoplastic adult brain (frozen autopsy tissue)

Project description:DNA hypomethylation could lead to activation of alternate promoters in GBM. We profiled DNA methylation and H3K4me3 genome-wide, and also performed expression and copy number analysis on the same samples In this dataset, we include all expression data obtained for five GBMs and one normal brain. We identified loci with concurrent DNA hypomethylation and H3K4me3 in GBM, and analyzed expression of the nearest gene in the same sample using these data Six total samples were analyzed. Each GBM sample was compared to normal brain to obtain expression changes

Expression data measured by microarray of monocyte-derived dendritic cells from healthy individuals stimulated with LPS, influenza, or left unstimulated

Project description:Variation in individuals' responses to environmental factors is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and stimulated dendritic cells (DCs) derived from the peripheral blood of healthy individuals. We stimulated the primary DCs with E. coli lipopolysaccharide (LPS) or influenza virus. Using serial replicate samples, we selected genes that showed evidence of reproducibility within the serial replicates. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and magnetically sorted them for CD14+CD16- monocytes. We then differentiated the monocytes into monocyte-derived dendritic cells (MoDCs) by culturing the cells for 7 days with GM-CSF and IL-4. We stimulated the cells with E. coli lipopolysaccharide (LPS) for 5 hr or influenza (PR8 dNS1) for 10 hr. Finally, we lysed the cells and isolated total RNA for microarray.

Expression data from MCF7 breast epithelial cells in normoxic and hypoxic conditions.

Project description:G9a is able to silence gene expression in hypoxic condition by increasing histone H3K9me2. We have identified a set of genes that are negatively regulated by G9a in hypoxia-dependent manner. In this dataset, we include the expression data obtained from MCF7 breast epithelial cells that have been transfected with control (WT) or G9a shRNAs (KD) and exposed to either normoxia or hypoxia. These data are used to obtain 829 genes that are differentially expressed in response to hypoxia, and 205 genes that are sentisive to G9a level. 4 samples were analysed. We generated comparisons between WT and KD in normoxic as well as hypoxic condition. Genes differentially expressed in hypoxic condition were selected followed by selection of genes that lose this differential expression upon G9a knockdown.
