models, we can improve our insights into the mechanisms related to human
disease,» said corresponding author and Dr. Hugo J. Bellen, professor
of neuroscience and molecular and human genetics at Baylor College
of Medicine and an investigator at the Howard Hughes Medical Institute.

models in a variety
of organisms — yeast, nematodes, fruit

In addition, projects to perform genetic interaction screens on
disease genes in
model organisms (yeast, worm,

Fruit
flies serve as a good
model organism for understanding the molecular mechanisms behind many human
diseases — around 75 percent
of disease - causing genes are found in the species in a similar form.
Because the
fly modeled the key features
of the human
disease, researchers can now screen proteins and molecules quickly to see which might have therapeutic effects.
