Physical Sciences-Oncology Centers (PS-OCs) Network: Cell Line Project • Selected human immortalized cell lines • MCF-10A: non-malignant breast epithelial cells • MDA-MB-231: metastatic breast cancer cells • Scope of project was to have each PS-OC conduct their unique physical science measurements on the cell lines and share and cross-compare datasets • Cell lines were propagated by one PS-OC Investigator and distributed to one site at each of the 12 PS-OCs along with detailed SOP for cell culture of each cell line • Requirement to upload cell line data to a pilot data coordination site • Investigators presented results at Data Jamboree Meeting in January 2011 • Cell line project data will serve as a pilot dataset for building the PS-OC Data Coordination Center (DCC) • Currently a Network manuscript is in preparation describing the results of the project

Large Projects Examples of NIH Investment in Genomic Research • Therapeutically Applicable Research to Generate Effective Treatment (TARGET) • The Cancer Genome Atlas (TCGA) • Cancer Genome Anatomy Project/Cancer Genome Characterization Initiative (CGAP/CGCI) • Genome-wide association studies (GWAS) of common and complex diseases and follow-up (~60/450 grants are cancer-related) Data generated is made publicly available • ~20% of NIH ARRA funded genomic projects
Molecular Characterization of Cancer Tissues is Essential but not Sufficient • Each tumor has hundreds to thousands genomic alterations • Chromosomal changes: amplifications, deletions, translocations • Epigenetic changes • Mutations • Little is known about the cellular function of most genes, much less how sequence variants and mutations affect them • Distinguishing initiating vs. driver vs. passenger mutations • Drivers are defined as genes involved in tumor maintenance • Evidence is accumulating that multiple subclones exist within a tumor and their frequency varies between patients • As tumors evolve genes essential for survival may be different from those that were necessary early on • Genomic alterations result in cancer within specific context • Cell of origin • Other molecular alterations in genes that may have synergistic or antagonistic impact
ARRA Opportunity Question: Can a network be formed that would effectively address a current major scientific challenge: efficient transition from patient-based large multi-dimensional genomic data target validation small molecule modulators (therapy, not part of the initiative) How to advantage the flood of genomic data and accelerate the transition to treatments of patients based on the genomic profile of their cancer?

ARRA CTD2 Network • Each application included up to 3 mature projects • Functional network formed rapidly • Component centers share results “in real time” (pre-competitive) • Established an ethos of data and resource sharing with scientific community upon validation • IT WG developed file formats for data sharing compatible with Cancer Data Standards Registry and Repository (caDSR) within caBIG • Enabled experiments, using new data generated by the molecular characterization projects to identify candidate targets, small molecule modulators and mechanisms: one example was ovarian cancer
Cancer Target Discovery and Development (CTD2) Network *** probe acquired dependencies via RNA determine relevance (STK33; TBK1) *** probe acquired dependencies via proteins cancer genomics small-molecule probes *** (acquired dependency small-molecule probe kit in >400 genotyped cell lines) * small-molecule drugs cancer patients ** cancer genomics-based mouse models probe acquired dependencies via network analyses determine relevance (STAT3; C/EBP in GBM) ** * Decode the relationship of cancer genotype to acquired cancer dependencies and identify small molecules that target the dependencies (*Broad; *CSHL; *Columbia; *DFCI; *Dallas)
Summary of the CTD2 Network’s caOv Results The power of the network: made rapid progress by sharing data, working together and taking advantage of complementary, non-overlapping expertise to carry out the experiments. Each Center contributed: • Identified candidate signature to stratify patients into best and worst prognostic groups • Identified candidate targets for therapeutic development • Confirmed a subset of candidates by in vitro and ex vivo experiments • Identified candidate small molecules for a subset of confirmed targets • Plan to generate mouse models for in vivo screening of other candidate genes within a specific genetic context • Experiments are ongoing Critical lesson: collaborative efforts to integrate several methods can yield exponential gains relative to the incremental gains achieved through improving any single method (united they are more than a sum of parts)
CTD2 Network Research Mission • Shift current research paradigms in translation pathway of patient-derived multidimensional genetic data to the clinic and utilize novel concepts, approaches and methodologies • Develop research that will exert a sustained influenceon the field • Develop a pre-competitive culture to ensure sharing of data, methods (analytical, experimental) and reagents within the network and the scientific community at large
Goals for the New Network • Accelerate the translation of patient genomic data into clinical application • Innovate the integration of computational mining large scale genomic data analyses • Make tools available through web • Identify and confirm new therapeutic target candidates • Identify and confirm novel modulators within specific cancer context (cellular or mutational) in vitro (cell lines) or in vivo (cancer models) • Small, stereochemically “interesting“ molecules • Use of novel organist chemistry – molecules more “natural products-like” • Mature molecules: optimize activity, structure activity relationship, systematic variation of stereochemistry • siRNAs • Multi-expertise team • Share models and reagents with the scientific community • Share data and methods with the scientific community through the web • As genomic data become available from TARGET, TCGA etc.,: be nimble, flexible and open to new opportunities
