How to make ImmPort data fit for secondary use

1. How to make ImmPort data fit for secondary use Barry Smith http://ontology.buffalo.edu/smith

2. Goals of ImmPort • Accelerate a more collaborative and coordinated research environment • Create an integrated database that broadens the usefulness of scientific data • Advance the pace and quality of scientific discovery • Integrate relevant data sets from participating laboratories, public and government databases, and private data sources • Promote rapid availability of important findings • Provide analysis tools to advance immunological research

3. Improve immunology research through enhanced • Collaboration • Coordination • Discoverability • Integration • Analyzability Hypothesis: all of these ends will be promoted by describing ImmPort data using terms from shared high quality ontologies

4. ImmPort data is already being tagged with ontology terms For example • where data is prepared to meet FDA requirements • where data is published to meet NIH mandates for reusability • in the post-submission phase, where data is analyzed by third parties But this tagging is • partial • uncoordinated • uses ontologies and analysis tools of varying quality

7. SDY 165: Characterization of in vitro Stimulated B Cells from Human Subjects shared to Semi-Public Workspace (SPW) Project During the human B cell (Bc) recall response, rapid cell division results in multiple Bc subpopulations. RNA microarray and functional analyses showed that proliferating CD27lo cells are a transient pre-plasmablast population, expressing genes associated with Bc receptor editing. Undivided cells had an active transcriptional program of non-ASC B cell functions, including cytokine secretion and costimulation, suggesting a link between innate and adaptive Bc responses. Transcriptome analysis suggested a gene regulatory network for CD27lo and CD27hi Bc differentiation.  • In vitro stimulated B cells from human subjects • B cell receptor editing

10. Discoverability: examples • Find [ImmPort] data pertaining to in vitro stimulated B cells from human subjects • Find studies of genes associated with B cell receptor editing in human subjects • Find all data in public and government databases relating to B cell receptor editing

11. Discoverability through literature search Two queries: • In vitro stimulated B cells from human subjects • B cell receptor editing on • Pubmed • MeSH (Medical Subject Headings) • Google

22. B cell receptor editing GO:0002452

23. GO definition GO provides a definition

24. and position in GO hierarchy -- hierarchy allows logical reasoning

25. GOPubMed: 179 results for “B cell receptor editing”

26. (B cell receptor editing Zand) AND ("Zand"[au]) why are zero documents retrieved?

27. Proposal1. Tag ImmPort SDY abstracts with GO URIs2. Publish the results to the GO Annotation database During the human B cell recall response, rapid cell division results in multiple B cell subpopulations. RNA microarray and functional analyses showed that proliferating CD27lo cells are a transient pre-plasmablast population, expressing genes associated with B cell receptor editing. Undivided cells had an active transcriptional program of non-ASC B cell functions, including cytokine secretion and costimulation, suggesting a link between innate and adaptive Bc responses.

34. ImmPort Templates How specify “Subject Phenotype”?

35. NG / BISC proposal create controlled vocabularies (ontology drop down lists) for fields currently populated by submitters with free text

36. Files in SDY 165

38. lk_sample_type proposal: where controlled vocabularies exist, provide definitions for all terms

39. Two kinds of definitions • human readable definitions support consistency of data entry • logical definitions • allow logical analysis of data • support aggregation of data • allow automatic validation of consistent data entry Definitions can often be taken over from already existing public domain ontologies such as GO • use of ready-made definitions supports discoverability, and creates automatic linkage to huge bodies of public domain data

49. Other strategies to simplify creation of structured data for submission into ImmPort • ELN: Electronic Lab Notebooks • PRIME: “Contur ELN has been automating the process of data deposition into ImmPort, making it much easier for our researchers to submit data to ImmPort” • CTMS: Clinical Trial Management Systems • EHR: Electronic Health Records • experiments to prepopulate EHR data into CTMS and from there into case report forms (and into ImmPort?) • Minimal Information Checklists
