Using gene-activity scores to link human alcohol risk with animal models

A Framework for Translating Polygenic Findings Related to Alcohol Use Disorder Across Species

NIH-funded research University of California, San Diego · NIH-11162497

This work builds a gene-based score to connect human genetic risk for alcohol problems with animal behaviors to help make lab research more useful for people with alcohol use disorder.

What this research studies

The team combines large human genetic studies of alcohol use with experiments in rodents to create a "polygenic transcriptomic risk score" (PTRS) that sums genetically predicted activity across many genes. Because PTRS works at the gene level, researchers can map those gene signals to matching genes in mice or rats and see whether the human-based score predicts alcohol-related behaviors in animals. The project uses existing human GWAS datasets plus rodent behavioral testing and genetic analyses to test this cross-species translation approach. If the PTRS predicts relevant animal behaviors, it can help researchers pick better animal models and biological targets for future treatments.

Who could benefit from this research

Good fit: Ideal participants are people whose genetic data and alcohol use information are already included in large research cohorts or biobanks.

Not a fit: People looking for immediate clinical treatment or personal therapy should not expect direct benefit from this basic translational research.

Why it matters

Potential benefit: If successful, this approach could make animal research better reflect human biology and speed discovery of treatments for alcohol use disorder.

How similar studies have performed: Polygenic risk scores are commonly used in human genetics, but applying gene-based PTRS across species is a novel and largely untested idea.
