Project description:FGFR1 mediated changes in gene expression at different stages of JOCK1 prostate cancer progression JOCK1 mice which express a prostate localize inducible version of the FGFR1 gene (iFGFR1) were used to determine what are the changes in gene expression at distinct stages of JOCK1 tumor progression. Activation of iFGFR1 is mediated by biweekly treatements of JOCK1 mice with AP20187 (50mg/kg). Wild type mice were treated for 24 hours with CID as a control, while JOCK1 were treated with CID for 4, 12, 24 and 52 weeks. All these treatments began at 12 weeks of age. After treatment mouse prostates (ventral and dorso-lateral prostate lobes), were dissected, placed in RNAlater and incubated at -800C. Tissue was thawed and placed in TRIzol (Invitrogen) for RNA isolation according to the manufacture. Once RNA was removed, a RNA cleaning step was performed using Qiagen RNEasy columns as described by the manufacturer. Time points were performed in triplicate and each array represents a single prostate. Labeling and hybridization to the mouse Affymetrix gene array 430 2.0 was performed by the Baylor College of Medicine microarray core. All hybridizations were performed at the same time.

Project description:Dosage compensation ensures that males and females, despite unequal number of X chromosomes, equalize for X linked gene expression. In Drosophila, it is achieved by a two-fold up-regulation of most of the genes present on the male X chromosome, and requires the association of the Dosage Compensation Complex (DCC) on the X chromosome. One of the main intriguing aspects of dosage compensation is how this complex is able to target specifically hundreds of sites only on the X chromosome in order to ensure dosage compensation. In order to better understand the targeting of the DCC and the dosage compensation mechanism, we have then decided to analyze the distribution of the DCC as well as the expression levels in male and female in a more complete and precise manner, using microarrays. In this experiment, we present the data used to analyse the distribution of the MSL-1 and MSL-3 protein (part of the DCC complex) on the X chromosome in WT embryos aged from 0H-14H, as well as the distribution of MSL-1 in embryos aged from 4-6H and in male III instar salivary glands. The DNA amplified from the specific immunoprecipitation (MSL-1 or MSL-3 IP) were labelled using Cy5-dCTP and hybridized against DNA amplified from a non specific immunoprecipitation (mock IP), labeled with Cy3 dye. In parralel we present the data used to analyse the expression profile of X-linked genes in WT male or female III instar larvae salivary glands. The cDNA amplified from the RNA extracted from the male or female salivary glands were labelled using Cy5-dUTP and hybridized against the reference sample, labelled with Cy3-dUTP (pool RNA from ON embryos, adultes, and salivary glands mixed at a ratio 1:1:1.and amplified as the RNA from salivary glands). We used for this study a cDNA array developed by the Genecore facility in EMBL, covering the DGC1 and DGC2 cDNA libraries from the Berkeley Drosophila Genome Project, which represents more than 70% of the coding Drosophila genome.

Project description:modENCODE_submission_720 This submission comes from a modENCODE project of David MacAlpine. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: Most terminally differentiated Drosophila tissues are either polyploid or polytene. Unlike normal chromosomes, where the entire chromosome must be replicated exactly once, polytene chromosomes are often differentially replicated with many regions underreplicated and some overreplicated. We will characterize five different polytene tissues using comparative genomic hybridization (CGH) to identify differentially replicated regions of each chromosome. These studies will also identify tissue specific amplicons, where the replication mediated amplification of specific loci is essential for up-regulation of mRNA levels encoding proteins critical for development. The differential replication of polytene chromosomes in Drosophila will provide a unique opportunity to understand how developmental cues and chromosomal domains influence replication initiation.

Project description:Microarray based CGH was conducted over a group of 29 strains of S. Enteritidis spanning different epidemiological periods in Uruguay, plus 6 other S. Enteritidis strains isolated from distant geographical regions. We also included 9 Salmonella enterica strains of other serovars isolated in Uruguay. A S. Enteritidis dispensable genome of 233 chromosomal genes and high extent of variation in virulence plasmid was found. Strains isolated before the epidemic show the highest genomic differences as compared with the PT4 reference strain. Comparison with the gene content of other serovars demonstrate extensive horizontal gene transfer between circulating strains beyond serovar definition. Our results show that the epidemic of S Enteritidis in Uruguay was produced by the introduction of strains closely related to PT4, and corroborate the extensive genetic homogeneity among S. Enteritidis isolates worldwide. Phage SE14 emerges as the only specific region for S. Enteritidis. Genetic differences detected in pre-epidemic strains, mainly associated with the absence of phage SE20, suggest that genetic features encoded in this phage may be related to particular epidemiological behavior.
