Functional Genomics of the Developing Endocrine Pancreas • cDNA libraries from pancreatic tissue • Consortium libraries (Currently > 34,000 ESTs) • Pancreatic transcripts: 10,364 EST assemblies (from 25,866 mouse ESTs) • Novel transcripts: 3190 assemblies with only consortium ESTs • relevant dbEST libraries • Microarray studies on pancreatic tissue • Genome wide-survey for genes expressed • Pancreas chip • Validated sequences of interest • Novel sequences from libraries Goal: Identify genes expressed in the developing endocrine pancreas
CBIL Project Architecture PlasmoDB AllGenes EPConDB Sequence & annotation Gene index (ESTs and mRNAs) Microarray expression data experimental annotation Relational DB (Oracle) with Perl object layer GUS RAD
Identify shared TF binding sites Genomic alignment and comparative Sequence analysis TESS (Transcription Element Search Software) RAD GUS EST clustering and assembly
EPConDB: Content and Features • Pancreas clone sets • Panc Chip Clone sets 1.0, 1.5, 2.0 • Transcripts found in consortium libraries • Novel transcripts discovered from consortium libraries • Microarray results • Using Incyte’s GEM (genome-wide survey) • Using Panc Chip • Genes expressed in pancreas • AllGenes queries: function, chromosomal location, keyword, accession, libraries • Pathways
The Future of EPConDB • Display new microarray results • Kaestner: labeling study, developmental series, mutant mice • Central repository for pancreatic experiments • 2-color cDNA, long oligos, Affymetrix, SAGE, etc. • Provide tools for microarray import/export • MGED: MIAME-compliance, MAGE, Ontology [Standard Annotation] • John Hutton/ Ron Taylor (UCHSC) • Beta Cell Biology Consortium? • Starting point for analysis • Provide tools: Xcluster, PaGE, Speed Normalization Package • Download datasets • Coordinate experiments to facilitate comparison • Integrate experiments • With genomic data (AllGenes), proteomics? Atlases? • Build networks Goal: Comprehensive understanding of pancreatic gene expression

Microarray Gene Expression Database group (MGED) International effort on microarray data standards: • Develop standards for storing and communicating microarray-based gene expression data • defining the minimal information required to ensure reproducibility and verifiability of results and to facilitate data exchange (MIAME, MAGEML-MAGEDOM) • collecting (and where needed creating) controlled vocabularies/ ontologies. • developing standards for data comparison and normalization. http://www.mged.org
