Project description:Differential expression of genes in E. coli MG1655 strains with deletions of fis and hns was assessed under early-exponential, mid-exponential, transition-to-stationary and stationary phases of growth in LB medium.
Project description:RNAs were extracted from entorhinal cortex of human suicide patients with major depression and matched control subjects. The transcription profile was investigated by Agilent microarray platform and quantitative real-time PCR to reveal alterations in neuronal functions in this brain region.
Project description:IHF and HU are two heterodimeric nucleoid associated proteins (NAP) that belong to the same protein family but interact differently with the DNA. IHF is a sequence-specific DNA-binding protein that bends the DNA by over 160o. HU is the most conserved NAP which binds non-specifically to duplex DNA with a particular preference for targeting nicked and bent DNA. Despite their importance, the in-vivo interactions of the two proteins to the DNA remain to be described at a high resolution and on a genome-wide scale. Further, the effects of these proteins on gene expression on a global scale remain contentious. Finally, the contrast between the functions of the homo- and heterodimeric forms of these proteins deserves the attention of further study. Here we present a genome-scale study of HU- and IHF-binding to the E. coli K12 chromosome using ChIP-seq. We also perform microarray analysis of gene expression in single- and double-deletion mutants of each protein to identify their regulons. This data is for microarrays measuring gene expression changes in the various ihf mutants when compared to the wildtype.<br>
Project description:Total RNAs were extracted from the hippocampus and prefrontal cortex of anxious mice. The transcriptome of the two brain regions were investigated using a custom made Agilent 8 x 15k features oligo microarray.
Project description:Comprehensive gene expression profiles of seven NK cell lines and eleven clinical samples of NK cell neoplasm were analyzed to detect tumor-specific genes. The gene expression profiles of NK cells from normal donor were analyzed as control samples.
Project description:Effect of 6-OHDA mediated ablation of midbrain dopamingeric neurons on the transcriptional profile of midbrain ependymoglia cells (neuronal stem cells) in newts.
Project description:In order to unravel the molecular mechanisms involved in the resistance of biofilm-grown <br>Burkholderia cenocepacia cells against high concentrations of disinfectants, the present <br>study focussed on the transcriptional response in sessile B. cenocepacia J2315 cells<br> following exposure to high levels of H2O2, NaOCl or chlorhexidine. In addition differences<br> in gene expression were examined between untreated B. cenocepacia sessile cells and <br>B. cenocepacia planktonic cells.
Project description:Generation of monocyte-derived dendritic cells (DC). Immature DC were prepared from peripheral blood mononuclear cells (PBMCs) isolated from whole blood of healthy donors. A minimum of 3 individual donor blood was used for each experiment. PBMCs were incubated with anti-CD14 microbeads (Miltenyi Biotec, Bergish Gladbach, Germany) as specified in the manufacturer's instructions. The isolated monocytes were resuspended at 10^6 cells/ml in medium supplemented with 10% human AB serum, 100 ng/ml GM-CSF (Leucomax; Novartis, Camberley, UK) and 50 ng/ml IL-4 (Peprotech EC Ltd, London, UK), cultured in tissue culture flasks. On day 7 the cells were defined as immature DC with low/intermediate HLA-DR expression. Microarray analysis of the effects of Paclitaxel and LPS on DC. Total RNA was extracted from day 7 DC which had been treated for 2 h with 1 ug/ml LPS or 100 uM paclitaxel for 2 h then washed and returned to culture for 24 h. This was used as a template to generate Cy3-labelled cRNA, using the Low RNA Input Linear Amplification Kit (Agilent). This was used as a probe on the Whole Human Genome Microarray (4x44K) slide (Agilent). Slides were scanned using the Agilent scanner and data extracted using Feature Extraction Software 9.5.3 (Agilent). Subsequent data analysis was performed using GeneSpring GX software.
Project description:T-ALL Xenograft Histone Modification at ERG locus: The cells used are human T-acute lymphoblastic leukaemia cells that have been propagated in NOD/SCID mice. T-ALL8,T-ALL16, T-ALL27, T-ALL29, T-ALL30 and T-ALL31 are cells from six different patients. Normalized data files containing chromosome 21 data are available on the FTP site for this experiment in the E-MTAB-431.additional.zip archive.
