Translational Research

The application of research findings in one domain

of study to another, (usually broader) domain.

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?

• 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
