Better cures require better models.

Drug development depends on in vivo research models to evaluate efficacy and safety. However, current models frequently fail to translate. We developed a framework to predict better models that could accelerate drug development.

Organism Selection concept illustration

Traditional “supermodel” organisms have helped us study human biology.

But no organismal model is perfect — different aspects of human biology require different or multiple models. We developed an approach to predict which organisms could best model your human gene of interest.

What if we could use data to select model organisms based on relevance to your specific gene of interest?

Our approach:
  • We identified 62 experimentally tractable organisms across the eukaryotic tree of life and compared proteins in these organisms to human proteins.
  • By taking into account both protein structural characteristics and phylogenetic distance, we identified organisms with proteins unexpectedly similar to humans.

Our results surprised us.

For example, zebrafish, algae, and paramecium are good models in many instances, despite their distance from humans.

We've followed up with experimental testing.

We started testing our hypotheses by modeling human genetic diseases in algae and worms.
