Tools For Bringing The Dog Genome Project Into the Biology Classroom

 

Dr. Elaine Ostrander's lab at the National Institutes of Health is trying to understand disease susceptibility, behavior, and variation that occurs throughout domestic dog breeds. 

Her team works with dog owners, breeders, and the American Kennel Club to collect DNA samples from dogs of varying phenotypes and applies the most sophisticated genomic technologies to understand variation in behavior, morphology and disease susceptibility in these breeds. They also lead The Dog Genome Project.

Using saliva samples to gather dog DNA, this research helps us understand the genetic underpinnings of the same or similar phenotypes in humans, highlighting mutations, genes, or pathways important to developmental and disease processes. 

Dogs are ideal for such studies since each dog breed represents an isolated and relatively pure breeding population, dog families are larger—much more so than humans, and dog owners ensure the health of their pets by vigilant screening on the part of a highly motivated veterinary community. Dog are domestic pets that also share many of the same environmental exposures as humans, which helps us to understand gene-environment interactions.

Below are helpful online resources for coming up to speed with the dog genome and its promising findings chosen to help both teacher and student. These include a recent videos of Dr. Ostrander presenting her findings, important published research, and powerful images for use in talks or handouts.
