1 How to make ImmPort data fit for secondary use Barry 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

6 SDY 165: Characterization of in vitro Stimulated B Cells from Human Subjects shared to Semi- Public Workspace (SPW) Project

7 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

9 Pubmed

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

12 Pubmed

13 PubMed retrieves 144 results for “In vitro stimulated B cells from human Subjects” – Zand paper not found

14 PubMed retrieves 0 results for “Zand[Author] AND In vitro stimulated B cells from human subjects”

15 Pubmed retrieves 179 results for “B cell receptor editing” – Zand paper not found

16 MeSH results for “In vitro stimulated B cells from human subjects”

17 MeSH results for “in vitro stimulated B cells from human subjects”

18 MeSH results for “B Cell receptor editing”

19 Google retrieves 180 results for “In vitro stimulated B cells from human subjects” – Zand paper not found

21 How to make this [ImmPort data] 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. discoverable?

22 B cell receptor editing GO:

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 Proposal 1. Tag ImmPort SDY abstracts with GO URIs 2. 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. Transcriptome analysis suggested a gene regulatory network for CD27lo and CD27hi Bc differentiation.

33 ImmPort Templates How specify Race if Race = ‘Other’?

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

37

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

51 Checklist strategy for creating public data repositories via journals 75% of articles in Cytometry A are MiFlowCyt compliant Result: a growing repository of flow cytometry data (flowrepository.org) OBI = Ontology for Biomedical Investigations, an ontology to support creation of structured data about clinical and biological experiments

55 NIAID Sample Data Sharing Plan (Last Reviewed February 12, 2013) Sharing of data generated by this project is an essential part of our proposed activities and will be carried out in several different ways. Presentations at national scientific meetings. … it is expected that approximately four presentations at national meetings would be appropriate. … Annual lectureship. A lectureship has brought to the University distinguished scientists and clinicians … Newsletter. The [disease interest group] publishes a newsletter … Web site of the Interest Group. The [interest group] currently maintains a Web site where information [about the disease] is posted … Annual [Disease] Awareness week…. SAGE Library Data. It is our explicit intention that these [Serial analysis of gene expression] data will be placed in a readily accessible public database. …Serial analysis of gene expression

56 NIAID Sample Data Sharing Plan SAGE Library Data. It is our explicit intention that these [Serial analysis of gene expression] data will be placed in a readily accessible public database. …Serial analysis of gene expression – but how will these data be described?

57 Proposal All data sharing plans for NIAID-funded research should require: paper abstracts and SDY summaries be tagged with ontology terms tables and figures in papers be tagged with ontology terms
