Linking human and animal genetics to better understand addiction

Building Bridges to Allow Cross-species Translational genetics for the Study of Addiction

NIH-funded research University of California, San Diego · NIH-11163522

This project uses gene activity patterns to connect human genetic findings with animal models so scientists can learn more about what causes addiction.

What this research studies

Researchers will combine large human genetic studies with experiments in animals and molecular data to find shared biological signals for addiction. They plan to convert human polygenic signals into comparable gene-expression patterns and test those patterns in model organisms. The team will use transcriptome data (how genes are turned on or off) to bridge species differences and highlight pathways that matter across humans and animals. This work tries to make genetic discoveries more useful for understanding disease mechanisms and for guiding future treatments.

Who could benefit from this research

Good fit: People with a history of alcohol, tobacco, cannabis, or opioid use disorder — or those willing to contribute genetic or biological data related to substance use — would be most relevant to the goals of this work.

Not a fit: Individuals seeking immediate clinical care or urgent addiction treatment should not expect direct, near-term benefits from this research project.

Why it matters

Potential benefit: If successful, this approach could reveal the biological pathways behind addiction and point to new targets for treatments or prevention.

How similar studies have performed: Large human GWAS and polygenic risk approaches have identified genetic regions linked to addiction, but applying transcriptome-based cross-species polygenic translation is a novel and largely untested approach.
