Genome-wide analysis of gene expression perturbed by Pontin shRNA in MCF7 subjected to normoxic and hypoxic conditions

ABSTRACT: 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.

Genome-wide analysis of gene expression perturbed by Pontin shRNA in MCF7 subjected to normoxic and hypoxic conditions

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.

Genome-wide analysis of gene expression perturbed by reptin shRNA in MCF7 subjected to normoxic and hypoxic conditions

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.

Transcription profiling of human monocytes and monocyte-derived macrophages subjected to normoxic or hypoxic conditions

Project description:Microarray analysis was carried out on human monocytes (Mono) and monocyte-derived macrophages (MDM) (n = 4 donors) that were subjected to normoxic (N) or hypoxic (H) conditions. Purified human monocytes and their MDM were cultured for 24 h in CSF-1 (5000U/ml) under normoxic or hypoxic conditions.

Expression of foetal gene Pontin is essential in protecting heart against pathological remodelling and cardiomyopathy

Project description:Cardiac remodelling is a key process in the development of heart failure. Reactivation of foetal cardiac genes is often associated with cardiac remodelling. Here we study the role of Pontin (Ruvbl1), which is highly expressed in embryonic hearts, in mediating adverse remodelling in adult mouse hearts. We observe that Pontin deficiency in cardiomyocytes leads to induced apoptosis, increased hypertrophy and fibrosis, whereas Pontin overexpression improves survival, increases proliferation and reduces the hypertrophic response. Moreover, RNAseq analysis show that genes involved in cell cycle regulation, cell proliferation and cell survival/apoptosis are differentially expressed in Pontin knockout and transgenic overexpression mice. Specifically, we detect changes in the expression of Hippo pathway components in the Pontin knockout and transgenic mice. Using a cellular model we show that Pontin induces YAP activity, YAP nuclear translocation, and transcriptional activity. Our findings identify Pontin as a modulator of adverse cardiac remodelling, possibly via regulation of the Hippo pathway. This study may lead to the development of a new approach to control cardiac remodelling by targeting Pontin.

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.
