H1299 cells: p53 transcriptional response in hypoxia

ABSTRACT: Transcriptional profiling of H1299 non-small cell lung carcinoma cells transfected with either wt p53 or mut(175) p53 driven by the 5xHRE promoter (5 repeats of hypoxia-inducible factor response elements) and treated for 16 h with normoxia (21% O2) or hypoxia(<0.1% O2). 5xHRE promoter ensures that p53 expression is induced in hypoxic conditions only. Goal was to determine the transcriptional response of p53 in hypoxia and the 175 p53 mutant was used as a control as it is DNA-binding defective and transcription-incompetent mutant. Four-condition experiment: wt p53-transfected H1299 cells treated with normoxia, mut p53-transfected H1299 cells treated with normoxia, wt p53-transfected H1299 cells treated with hypoxia, mut p53-transfected H1299 cells treated with hypoxia. Biological replicates: 1 normoxic sample with wt p53, 1 normoxic sample with mut p53, 3 hypoxic samples with wt p53, 3 hypoxic samples with mut p53.

The effect on gene expression by p53 family members and the knockdown of AKR1B10

Project description:To evaluate the effect on gene expression by p53 family members and AKR1B10, we overexpressed p53 family members in H1299 cells or knocked down AKR1B10 in HCT116 cells and evaluated the gene expression by microarray analysis. Gene expression was measured in H1299 cells infected with adenovirus expressing p53, p63g and p73b, and in HCT116 cells transfected with siRNAs targeting AKR1B10 and then treated with adriamycin.

RNA-seq of H1299 cells stably transfected with empty vector or the p53 mutant R273H.

Project description:This experiment aimed to determine the genes that were upregulated when mutant p53 (R273H) was expressed. We used H1299 lung cancer cells that are endogenously p53-null and overexpressed the p53 mutant.

NCI-H1299 cell line transfected with human DENND2D and vector

Project description:Gene expression for NCI-H1299 cell line transfected with human DENND2D and vector (pcDNA3.1/V5-His TOPO TA vector) respectively. The microarray experiment was designed to perform four replicates for each H1299-DENND2D and H1299-vector sample. cRNA used in replication 1 and 2 was from the same label reaction to perform the hybridization replicates.

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.
