3 What am I doing here? Next Generation Sequencing Next Generation Web Future challenges Genome Canada Bioinformatics Platform

4 Better tech: less DNA, more sequence 44μm 70nm

5 PhytoMetaSyn

6 Sprockets: Hierarchical Gene Models from ESTs Developed in collaboration with BASF Plant Sciences

7 Genozymes

8 Hydrocarbon Metagenomics

10 Exploring gene expression patterns CAVEman Java 3D-based, world-first complete 3D human body atlas (adult male) – 2,335 organs, hierarchical organization following Terminologia Anatomica Numerous applications involving mapping of genetic and disease data More information: Patient MRI stack mapped onto atlas and registered by landmarks Pharmacokinetics visualization (Absorption-distribution-metabolism- excretion of Aspirin)

11 Basic Research Archaeal UV-light response Large-scale human genome organization ING-protein interactions (cancer and ageing-rated proteins)

12 Research Applications Kidney transplants: improved rejection diagnostics in Edmonton Mad cow disease/chronic wasting disease: live diagnostics Desulf.: mechanisms of oil pipeline corrosion and its prevention

13 DNA Diagnostics Discovery for Mad Cow PreclinicalClinicalPreinoculation Controls Control animal #6 Ball toy Photo: S. Czub, CFIA Lethbridge

14 Next-gen Motif finding (elk dataset) 61 blood samples 107 million base pairs 432 billion pairwise alignments ( ) mers or smaller Uninfected Infected 3 universal Infected Thousands of animal coverage/timepoint combos (CPU intensive) Decypher hardware accelerator

15 Motif Results

16 ↑ EVI1 ↑PLZF Retrovirus PrP sc (+?) ↓PLZF-controlled genes Infectious agent Circulating Nucleic Acids Endogenous Retrovirus? Consistent with protein-only evidence… Neurovirulent? (e.g. M.L. Labat 1999) Possible mode of action? Virus particles? ~25nm PrP Amyloid fibres Vacuole Manuelidis et al, PNAS 2007 Protected promoters (Motifs A & B) Feedback PrP Integration Nucleoprotein complexes Cell death CNA Export Carp et al., EMBO J., 2006 Leblanc et al., EMBO J Stengel et al., Biochem. Biophys. Res. Commun Lee et al., Biochem. Biophys. Res. Commun Etc. Activation

17 Better tech: less input, more results Better tech: less DNA, more sequence Generate Manuscript Now Generate Manuscript Now

18 Where are we at? Bioinformatics Web Emerging Technologies Life Sciences Semantic Web Source: Gartner Inc.

19 How software works… Functions/ Rules Parameters/Input Results/ Output (article, allele,…) (Gene name, DNA sequence, QTL…)

20 The problem with the Web Once you label me, you negate me. Søren Kierkegaard 1998 Now

21 Bluejay Comparative genomics BioMoby linking Waypoints Gene expression integration

22 The task at hand (biologist) Sequencer Data File (Binary) ACCGT… Known Proteins BLAST Report (related proteins) (computer scientist)

29 The need for shoehorns The current vision of the Semantic Web intends to create a new structure starting up with no reference to its vast, functioning, but more primitive predecessor … things just don’t happen like that

30 All the Web as Workflows Seahawk Proxied Web page Drag ‘n’ drop Seahawk prompting

31 What’s Ahead? The more a man learns, the more he realizes how little he knows

32 Semantic Web

34 Take home messages As tech improves, we can ask better questions We will need shoehorns to access existing resources for the foreseeable future
