Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.

Project description:To examine the role of COX7RP in breast cancer cells, MCF7 cells, which were stably transfected with COX7RP (COX7RP-MCF7) or control vector (vector-MCF7), were cultured in normoxic and hypoxic condition. Microarray analysis showed that COX7RP modulates metabolism-associated genes.
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.
Project description:In order to investigate the role of reptin methylation on the expression of hypoxia-responsive genes across the whole genome, we performed a microarray analysis from RNAs isolated from MCF7 cells expressing either control shRNA (shRNA) or reptin shRNA (shreptin) in normoxic and hypoxic conditions. MCF7 cells were transiently transfected with either non-specific shRNA or reptin shRNA in replicates. Cells were grown for 24 hours before being exposed to either normoxic (21% oxygen) or hypoxic (1% oxygen) conditions for 18 hours. Cells were then lysed and RNA was isolated.
Project description:In order to investigate the role of Pontin methylation on the expression of hypoxia responsive genes across the whole genome, we performed a microarray analysis from RNAs isolated from MCF7 cells expressing either control shRNA (shNS) or Pontin shRNA(shPontin) in normoxic and hypoxic conditions. MCF7 cells were transiently transfected with either non-specific shRNA or Pontin shRNA in replicates. Cells were grown for 24 hours before being exposed to either normoxic (21% Oxygen) or hypoxic condition (1% oxygen) for 6,9 hours. Cells were then lysed and RNA isolated.
