  1. Research • In the Post-Genomics • Era Martina McGloughlin, Biotechnology Program and Life Sciences Informatics Program UC Davis

  2. UC Davis Biotechnology Program UC Systemwide Life Sciences Informatics Program “Biology in the 21st century will increasingly become an information science” Leroy Hood, Jan 11, 1999 “Any cell has in it a billion years of experimentation by its ancestors” Max Delbruck, 1949

  3. Genomics • The massive interest and commitment of resources in both the public and private sectors flows from the generally-held perception that genomics will be the single most fruitful approach to the acquisition of new information in basic and applied biology in the next several decades. • If genomics were only to be a tool for the basic biologist, the benefits of this approach would be staggering, yielding new insights into fundamental processes such as cell division, differentiation, transformation, the development and reproduction of organisms and the diversity of populations. • The rewards in applied biology, however, have clearly attracted the private sector and public interest. These include the promise of facile new approaches for drug discovery, new understanding of metabolic processes and new approaches to determining qualitative and quantitative traits in plants and animals for breeding and genetic engineering.

  4. One Human Sequence Typed in 10-pitch font, one human sequence would stretch for more than 5,000 miles. Digitally formatted, it could be stored on one CD-ROM. Biologically encoded, it fits easily within a single cell.

  6. Paradigm Shift in Biology The new paradigm, now emerging, is that all the ‘genes’ will be known (in the sense of being resident in databases available electronically), and that the starting point of a biological investigation will be theoretical. An individual scientist will begin with a theoretical conjecture, only then turning to experiment to follow or test that hypothesis. Walter Gilbert. 1991. Towards a paradigm shift in biology. Nature, 349:99.

  7. Paradigm Shift in Biology To use [the] flood of knowledge, which will pour across the computer networks of the world, biologists not only must become computer literate, but also change their approach to the problem of understanding life. Walter Gilbert. 1991. Towards a paradigm shift in biology. Nature, 349:99.

  8. What’s Really Next The post-genome era in biological research will take for granted ready access to huge amounts of genomic data. The challenge will be understanding those data and using the understanding to solve real-world problems...

  9. DNA GenBank EMBL DDBJ Map Databases RNA Development ? Gene Expression? Proteins SwissPROT PIR PDB Circuits Metabolism? Regulatory Pathways? Phenotypes Neuroanatomy? Clinical Data ? Populations Biodiversity? Molecular Epidemiology? Comparative Genomics? Fundamental Dogma Although a few databases already exist to distribute molecular information, the post-genomic era will need many more to collect, manage, and publish the coming flood of new findings. If this extension covers functional genomics, then “functional genomics” is equivalent to biology.

  10. The actual sequence data makes up only 16% of the content; the other 84% is annotated. The is leads to a number of issues: How to structure databases for mining How to establish control vocabularies to establish integrity of searches What new algorithms are needed to facilitate processing and correlating the petabytes (1015 bytes) of information How can protein function be extracted for the purposes of diagnostics, drug discovery and therapeutics There are Problems with the HGP . ..

  17. Rhetorical Question • Which is likely to be more complex: • identifying, documenting, and tracking the whereabouts of all parcels in transit in the US at one time • identifying, documenting, and analyzing the structure and function of all individual genes in all economically significant organisms; then analyzing all significant gene-gene and gene-environment interactions in those organisms and their environments

  18. Business Factoids • United Parcel Service: • uses two redundant 3 Terabyte (yes, 3000 GB) databases to track all packages in transit. • has 4,000 full-time employees dedicated to IT • spends one billion dollars per year on IT • has an income of 1.1 billion dollars, against revenues of 22.4 billion dollars

  19. Examples of Biotech/IT Fusion Technologies • Genomics, proteomics and bioinformatics • Combinatorial –chemistry • Peptide libraries- tea bags, beads • Combinatorial -biology • Directed evolution • DNA Shuffling, Molecular Breeding • High throughput analysis • Nucleic Acid based Sequencing Microarrays • Photolithography • Mirrors • Spotted Chips • Semi-conductor • Protein based 2-D, electrospray/nanospray MS: MALDI-TOF, LC/MS/MS, SELDI • Imaging/optical biology • Biosensors, Bioelectronics and Bionetworks (Nanotechnology)

  20. Genomics, Proteomics and Bioinformatics • Genomics is operationally defined as investigations into the structure and function of very large numbers of genes undertaken in a simultaneous fashion. • Structural genomics includes the genetic mapping, physical mapping and sequencing of entire genomes. • Comparative genomics means information gained in one organism can have application in other even distantly related organisms. This enables the application of information gained from facile model systems to agricultural and medical problems. The nature and significance of differences between genomes also provides a powerful tool for determining the relationship between genotype and phenotype through comparative genomics and morphological and physiological studies. • Functional genomics Phenotype is logically the subject of functional genomics. Genome sequencing for most organisms of interest will be complete within the near future, ushering in the so called "post-genome era." Walter Gilbert directly speculated on the nature of biology in the "post-genome era": "The new paradigm, now emerging, is that all genes will be known (in the sense of being resident in databases available electronically), and that the starting point of a biological investigation will be theoretical.“

  21. Genomics, Proteomics and Bioinformatics • Proteomics At the molecular level, phenotype includes all temporal and spatial aspects of gene expression as well as related aspects of the expression, structure, function and spatial localization of proteins. The Proteome is the set of all expressed proteins for a given organism. • The next hierarchical level of phenotype considers how the proteome within and among cells cooperates to produce the biochemistry and physiology of individual cells and organisms. “Physiomics" is a descriptor for this approach. “Phenomics" The final hierarchical levels of phenotype include anatomy and function for cells and whole organisms. • Bioinformatics: Computational or algorithmic approaches to the production of information from large amounts of biological data, include prediction of protein structure, dynamic modeling of complex physiological systems or the statistical treatment of quantitative traits in populations in order to determine the genetic basis for these traits. • Unquestionably, bioinformatics will be an essential component of all research activities utilizing structural and functional genomics approaches

  22. Medical Bioinformatics: What is it? Biological Interpretation Laboratory/Clinical Experiments • Published Literature • Scientific/Medical Experts • Hi-throughput Screening Data • genotype sequencing • functional assays • DNA library • Patient Clinical Data • cancer phenotype • outcomes, treatments, age • Patient Samples • Tissues • Tumors • Model Systems • Rats • cultured tissues Informatics • Sample/Experiment Tracking • Data Processing, Quality Control • Statistical Analyses • Sequence Matching/Annotation • Functional Significance • User Access to Results

The company’s philosophy is to industrialize discovery and development, moving as many discovery and development operations as possible into a production mode.

  33. Expression Technologies There are currently four commonly used approaches to high throughput, comprehensive analysis of relative transcript expression levels. The enumeration of expressed sequence tags (ESTs), Serial Analysis of Gene Expression (SAGE), Differential Display Approaches, Array-based hybridization • The enumeration of expressed sequence tags (ESTs)from representative cDNA libraries. A method of approximating the relative representation of the gene transcript within the starting cell population. • GeneTrace Systems, HHMI, IMAGE Consortium, Incyte, The Institute for Genomic Research • Serial Analysis of Gene Expression.The enumeration of serially concatenated 9-11 base tags from specially prepared cDNA libraries. The frequency of particular transcripts within the starting cell population is reflected by the number of times the associated sequence tag is encountered within the sequence pop • Genzyme Molecular Oncology, Johns Hopkins University

  34. Expression Technologies • Differential Display Approaches Fragments defined by specific sequence delimiters can be used as unique identifiers of genes, when coupled with information about fragment length or fragment location within the expressed gene. The relative representation of an expressed gene within a cell can then be estimated based on the relative representation of the fragment associated with that gene within the pool of all possible fragments. A number of different approaches have been developed to exploit this hypothesis for comprehensive expression analysis. • Curagen Corporation - Quantitative Expression Analysis (QEA) • Digital Gene Technologies, Inc. - Total Gene expression Analysis (TOGA) • Display Systems Biotech - Restriction Fragment Differential Display-PCR (RFDD-PCR) • Genaissance • GeneLogic - Restriction Enzyme Analysis of Differentially-expressed Sequences (READS)

  35. Expression Technologies • Array-based hybridization Based on the exquisite specificity of nucleotide interactions oligonucleotides or cDNA can be used to selectively identify or capture DNA or RNA of specific sequence composition. The primary approaches include array- based technologies that can identify specific expressed gene products on high density formats, including filters, microscope slides, or microchips, and solution-based technologies relying on spectroscopic analyses, such as mass spectrometry.

  40. IP Challenges • June 5, 1995--Human Genome Sciences applies for a patent on a gene that produces a "receptor" protein that is later called CCR5. HGS has no idea that CCR5 is an HIV receptor. • December 1995--U.S. researcher Robert Gallo, the co-discoverer of HIV, and colleagues find three chemicals that inhibit the AIDS virus. Don’t how the chemicals work. • February 1996--Edward Berger at the NIH discovers that Gallo's inhibitors work in late-stage AIDS by blocking a receptor on the surface of T-cells. • June 1996--In a period of just 10 days, five groups of scientists publish papers saying CCR5 is the receptor for virtually all strains of HIV. • January 2000--Schering-Plough researchers tell a San Francisco AIDS conference they have discovered new inhibitors. Merck researchers are known to have made similar discoveries. • Feb. 15, 2000--The U.S. Patent and Trademark Office grants HGS a patent on the gene that makes CCR5 and on techniques for producing CCR5 artificially. The decision sends HGS stock flying and dismays researchers. • HGS: identified in whole or in part 95% of the 100,000 or so human genes. 100 human gene patents 7,500 pending.
