Drug Addiction Is Influenced by Interactions of Genes and Environment

Twin studies consistently show

that there is a heritable component

to drug abuse and addiction.

What are the gene variants?

Extramural StudyNIDA/Perlegen/WashUWhole Genome Scan for Nicotine Addiction

Intramural StudyNIDA

Affymetrix 500K screen for Drug Addiction

Many of These Genes Have Synaptic Functions

What is the functionalsignificance?

Need: Functional validation of gene variant

Capitalize on:NIH Knockout Mouse Project

High-throughput genetic and RNAi methods

Research in GEI (FY11&12)

Use genetic models to:

Investigate mechanisms of drug dependence

Test potential therapeutics

DBNBR Research Training

Framework to enhance cooperative activities among 16 NIH Institutes and Centers

Take on challenges in neuroscience that are best met collectively

Develop research tools and infrastructure that will serve the entire neuroscience community

Research Training Programs

NIH Roadmap FOR Medical Research

TransNIH initiative for a more efficient and productive system of medical research

Identifies themes in three main areas for support:

New pathways to discoveryResearch teams of the futureRe-engineering the clinical research enterprise

• NIDA lead on Interdisciplinary Research Training initiative– Support didactic and research experiences designed to provide

students with the knowledge and research experiences necessary to develop interdisciplinary solutions

– Allison Chausmer (lead program officer)
