Translational Research Type 1 Type 2 “Type 0” Researchers Clinicians The application of research findings in one domain of study to another, (usually broader) domain.
The Roles of Informatics Translational Informatics Biologic Knowledge Clinical Informatics Bioinformatics Clinical Knowledge
Promise of Translational Informatics • Diseases predicted by genes • Effectiveness of prevention • Diseases indicated by activation • Appropriate testing • Drug dose, toxicity and interactions • Drug effectiveness
Case Study • Patient with liver cancer and chest pain • Physician suspects pulmonary embolism • What is the best, least invasive test? • Will warfarin work to prevent further emboli? • What is the warfarin dose for this patient? • Will warfarin interact with other medications?
How does the nose form? Phylogeny Phylogeny Ontogeny Definitely genetic Not a big protein! 5 types of tissue Billions of cells Coordination in time and space How many genes? How many variants?

Now What? • This biology stuff is complicated • Translational research is about applying findings from one domain to another domain • Translational informatics is the key to communicating data and knowledge between domains • Translational informatics research is a new field • We still need: • Informatics research support (NCTR? NCTI? NIBI?) • Training (extramural and intramural) • Support for collaborative efforts (CTSAs) • Centralization of resources for efficiency and equity
