  2. The ACGT vision & principles • The ultimate objective of the ACGT project is the provision of a unified technological infrastructure which will facilitate • integrated access to multi-level biomedical data • development or re-use of open source analytical tools, accompanied with the appropriate meta-data allowing their discovery and orchestration into complex workflows. • ACGT will deliver a European Biomedical GRID infrastructure offering seamless mediation services for sharing data and data-processing methods and tools, and advanced security; • ACGT • focuses on clinical trials on Cancer (Wilms tumor, Breast) and • is based on the principles of • Open access (among trusted partners) • Open source • is not a standards generating exercise but a standards adopting one.

  6. Main challenges in ACGT • Grid middleware services, enabling large-scale (semantic, structural, and syntactic) interoperation among biomedical resources and services; • Master ontology (on Cancer) through semantic modelling of biomedical concepts using existing ontologies and ontologies developed for the needs of the project; • Open source bioinformatics tools and other analytical services; • Semantic annotation and advertisement of biomedical resources, to allow metadata-based discovery and query of tools, and services; • Orchestration of data access and analytical services into complex eScience workflows for post genomic clinical research and trials on cancer; • Meta-data descriptions of clinical trials to provide adequate provenance information for future re-use, comparison, and integration of results;

  7. UoO Nephroblastoma Multi-centric Oncogenomic Study JBI 2 UoS In Silico Oncology Study 3 IEO Prolipsis FORTH UoC Breast Ca Multicentric Oncogenomic Study 1 The ACGT clinical trials • Multicentric TOP trial – Breast Cancer • SIOP 2002 – paediatric nephroblastoma • In Silico modeling and simulation of tumor growth & response to treatment

  8. In silico modeling and simulation • Seeks to extract information related to tumor growth & response to treatment • Requires • access to multi-level clinico-genomic data. • implementation of a variety of processing tools and • specification of complex analytical workflows

  9. OMIM Swissprot-Uniprot Reactome GO medDRA NCIT FMA ICD 10 The ACGT master ontology • Priority: Ontology of entities involved in two carcinomas • Nephroblastoma and Breast Carcinoma • Terms from different terminologies & ontologies are integrated together • Hierarchy and Relations of terminologies & ontologies NOT incorporated (except FMA) • Sources used as a dictionary • Deficiencies present in each source in classification and relations: improved Diseases Disease - Gene Anatomy Protein Annotation Textbook Information Pathways Bio-processes Cell Anatomy Molecular Function Drug Databases

  10. End user tools An integrated visual environment • Clinical Trial Templates • Augmented by the ACGT Master Ontology • Graphical representation of data elements and processing steps in a clinical trial • Data mining and analytical tools • A variety of tools and applications Clinical trial workflows • Graphical representation of workflows • Processing modules attached to each other in a workflow

  12. Collaborations • ACGT is planning to develop strong links with other projects/initiatives for collaboration – harmonization, in areas such as • Grid middleware • HealthGrid • Biomedical data analysis • In Silico modelling and simulation • Biomedical Ontologies • SOA and metadata for biomedical applications • eScience workflows • Translational research on cancer
