Project description:An experiment was performed to compare global transcription patterns in two tissues of Lepidium sativum seeds at different times during imbibition leading up to, but not including, radicle protrusion from the seed (e.g. germination). RNA extractions from the two tissues were hybridised to CATMA Arabidopsis microarrays. The two tissues were the radicle and the micropylar endosperm cap that covers it. The interaction of these two tissues is thought to control the timing of germination though alterations in the extensibility of the radicle and the physical resistance of the micropylar endosperm cap to radicle penetration.

Project description:To assess natural variation in gene expression in Arabidopsis thaliana, genome wide gene expression variation was analyzed in a Ler/Cvi recombinant inbred line (RIL) population.The variation in expression could be explained for many genes by expression quantitative trait loci (eQTLs). These eQTLs are combined with regulator candidate gene selection to generate genetic regulatory networks.

Project description:The role and essentiality of silicon (Si) in plant biology has been debated for over 150 years in spite of numerous reports describing its beneficial properties. To obtain unique insights regarding the effect of Si on plants, we performed a complete transcriptome analysis of both control and powdery mildew-stressed Arabidopsis plants, with or without Si application, using a 44K microarray. Surprisingly, the expression of all but two genes was unaffected by Si in control plants, a result contradicting reports of possible direct effect of Si as a fertilizer. In contrast, inoculation of plants, treated or not with Si, altered the expression of a set of nearly 4,000 genes. Following functional categorization, many of the up-regulated genes were defense-related whereas a large proportion of down-regulated genes were involved in primary metabolism. Regulated defense genes included R genes, stress-related transcription factors, genes involved in signal transduction, the biosynthesis of stress hormones (SA, JA, ethylene), and the metabolism of reactive oxygen species. In inoculated plants treated with Si, the magnitude of down-regulation was attenuated by over 25%, an indication of stress alleviation. Our results demonstrate that Si treatment had no effect on the metabolism of unstressed plants suggesting a non essential role for the element, but that it has beneficial properties attributable to modulation of a more efficient response to pathogen stress. Experiment Overall Design: A loop design with complete dye-swap was used as experimental design for comparing plants submitted to four treatments and three biological replicates for a total of 24 Agilent Arabidopsis 3 microarrays. Two factors experimental factors : response to a compound (Silicon, treated or not treated) and disease state (Erysiphe cichoracearum, normal vs. diseased). Each factor had two levels. For each of the four combinations of factors, three plants were randomly selected. Thus a total of 12 plants were used for the experiment. RNA was extracted from rosette leaves.

Project description:Ewingâs Sarcoma (ES) is characterized by specific chromosomal translocations, the most common being t(11;22)(q24;q12). Additionally, other types of genetic abnormalities may occur and be relevant to explain the variable tumoural biology and clinical outcome. We have carried out a high-resolution array CGH and expression profiling on 25 ES tumour samples to characterize the DNA copy number aberrations (CNA) occurring in these tumours and to determine their association with gene expression profiles (GEO Series accession number: GSE8303) and their clinical outcome. CNA were observed in 84% of the cases. We observed a median number of 3 aberrations per case. Besides numerical chromosomal changes, smaller aberrations were found and defined at chromosomes 5p, 7q and 9p. All CNA were compiled to define the smallest overlapping regions of imbalance (SORI). Thirty five SORI were delimited. Bioinformatic analyses were conducted to identify subgroups according to the pattern of genomic instability obtained. Unsupervised and supervised clustering analyses (using SORI as variables) segregated the tumours into two distinct groups: one genomically stable (⤠3 CNA) and another genomically unstable one (> 3 CNA). The genomic unstable group showed a statistically significant shorter overall survival and was more refractory to chemotherapy. This report elucidates data about genomic instability in ES, based on CNA and expression profiling for the first time, and shows that a genomically unstable group of Ewing tumours is correlated with a significant poor prognosis. Experiment Overall Design: Comparative experiment: pheripheral blood pool of ten healthy female donors: CONTROL vs. 26 Ewing Sarcoma Tumour Samples. Experiment Overall Design: Note that although 26 samples were profiled, only 25 were analysed (sample #11 did not pass quality control).

Project description:BACKGROUND AND OBJECTIVES: Low-grade B-cell lymphomas include several subtypes of tumors with different degrees of histological, biological or clinical features. Differential diagnosis is frequently compromised by the lack of specific cytogenetic or molecular features. As a consequence, therapies remain in many lymphoma types largely based in common protocols with largely variable success. Our objectives were to describe and to compare the genomic profile of a series of samples from the most prevalent low-grade lymphoma subtypes; all of them systematically analyzed with the same approach. DESIGN-AND-METHODS: We carried out a high-resolution genomic DNA analysis (44K probes) in 87 low grade B cell lymphoma tumor samples that unambiguously presented the clinical picture, analytical features, and peripheral blood morphology and phenotype described for each entity. RESULTS: The genomic integrity of the samples was heavily compromised (80% of the tumors presented at least one aberration). This phenomenon also involved lymphoplasmocytic and marginal zone lymphomas that have not been previously studied by this genomic approach. New aberrations have been described for almost every subtype. We have also generated reports of the extension of the genomic instability, detecting distinct patterns of genomic instability within subtypes. INTERPRETATION-AND-CONCLUSIONS: The genomic profile of each subgroup showed substantive differences. The bioinformatic analysis of the data detected a set of new aberrations which were present in the majority of the subgroups and that pointed out to specific pathways, such as NF-kB (gains that involved REL, BCL11A and COMMD1) or DNA repair checkpoint pathways (deletion of 16q24 involving CDT1). Experiment Overall Design: Comparative experiment: pheripheral blood pool of ten healthy female donors: CONTROL vs. 87 Low grade Lymphoma tumour samples

Project description:BAC pool DNA hybridisation of barley to 44k Agilent microarrays. We have used two-channel Agilent expression microarrays to address thousands of gene sequences to individual BAC clones and contigs that form part of an emerging physical map of the large and unsequenced 5300 Mbp barley genome. By using two-colour processing, each array allows simultaneous co-hybridization of two independent BAC pools (SP), for which the data is analysed separately. As a general approach the method represents a cost-effective, highly parallel alternative to traditional gene-to-BAC addressing methods. By coupling the BAC address-data with gene-based genetic maps we were able to anchor thousands of BACs to the barley genetic map.

Project description:An experiment was performed to compare global transcription patterns in three tissues of Lepidium sativum seeds at different times during imbibition leading up to, but not including, radicle protrusion from the seed (e.g. germination). RNA extractions from the three tissues were hybridised to CATMA Arabidopsis microarrays. The three tissues were the radicle, the micropylar endosperm cap that covers it, and the non-micropylar endosperm. The interaction of the first two of these tissues is thought to control the timing of germination though alterations in the extensibility of the radicle and the physical resistance of the micropylar endosperm cap to radicle penetration.

Project description:Gene regulation in response to nutrient deprivation. Drosophila larvae of control w1118 or FOXO-21/25 null genotypes were grown to early 3rd instar and then either starved for 18h on PBS/agarose or grown on normal food. Adipose tissue (fat body) and muscle (body wall muscle) were dissected out, RNA extracted, and microarray analysis performed comparing starved to non-starved samples.
