Tiling path analysis to determine copy-number variation in 40 Utah/Morman and Yoruban population samples using NimbleGen technology

ABSTRACT: A copy-number variation (CNV) analysis was run on 40 CEU and YRI samples across an array set tiling across the human genome. The array contained 42 million oligos spread across 20 arrays. The final design provided 1 probe per 50bp average density across the genome.

Structural variations of DNA greater than 1 kilobase in size account for most bases that vary among human genomes, but are still relatively under-ascertained. Here we use tiling oligonucleotide microarrays, comprising 42 million probes, to generate a comprehensive map of 11,700 copy number variations (CNVs) greater than 443 base pairs, of which most (8,599) have been validated independently. For 4,978 of these CNVs, we generated reference genotypes from 450 individuals of European, African or Ea ...[more]

Transcription profiling of wild type, relA-, and relA-spoT- mutant strains of E. coli submitted to starvation for isoleucine

Project description:WT and mutant strains (relA-, relA-spoT-) were submitted to starvation for isoleucine. 40 minutes after starvation, RNA was extracted. All samples were compared to RNA from rapidly growing WT cells in identical medium.

Transcription profiling of rat heart, kidney and placenta from fetuses obtained from dams with diet-induced intra-uterine growth restriction vs. normal

Project description:Pregnant rats were randomly divided into two groups. Dams were then housed individually and fed throughout gestation a 22 % protein diet, representing the control group (C, n=5), or an 9% isocaloric protein diet, representing the low-protein (LP, n=6). Both diets were isocaloric, because the protein deficiency in the LP diet was compensated by the addition of carbohydrates. Feeding of LP diet began on the day of conception and continuing throughout pregnancy. The low-protien diet resulted in Intra-Uterine Growth Restriction (IUGR) of the fetuses. An additional processed data file, E-MEXP-1015_all_norm_calls.txt, is available for download from <a href="ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/MEXP/E-MEXP-1015/">ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/MEXP/E-MEXP-1015/</a>

Chromatin immunoprecipitation with p53-antibody of human osteosarcoma cell line Saos-2 infected with adenomviruses encoding GFP, or GFP with p53 H1 helix mutants EL or RE

Project description:ChIP-chip study using Saos-2 cell line infected with adenoviruses encoding GFP (Mock) or GFP together with the p53 H1 helix mutants EL or RE. DNA-protein-complexes were precipitated with monoclonal p53-antibody (clone DO-1). Mock-chromatin was immunoprecipitated in the absence of antibody. Three completely independent biological replicates were performed for each antibody, obtaining the corresponding input as total genomic DNA reference. Hybridizations were performed using Affymetrix GeneChip Human Tiling 2.0R Array set (7 arrays set). Affymetrix .BAR files and an additional processed data file containing the coordinates of the identified binding sites can be found in the FTP directory for this experiment. <A HREF="ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/MEXP/E-MEXP-1748">FTP directory</A>
