Contact: Kevin Jiang kevin.jiang@uchospitals.edu<\/a> 773-795-5227 University of Chicago Medical Center @UChicagoMed<\/p>\n The National Institute on Drug Abuse (NIDA) has awarded the University of Chicago a $12 million, five year grant to establish a national Center of Excellence to study drug abuse-associated behaviors by conducting research with rats. <\/p>\n Led by Abraham Palmer, PhD, associate professor of human genetics, the NIDA Center for Genome-Wide Association Studies in Outbred Rats will combine complex behavioral studies with recent technological advances in rat genetics to help scientists shed light on the genes behind drug addiction. <\/p>\n Rats have a long and storied history as an important animal model for research, especially in behavioral studies. But in recent decades, the use of rats has given way to mice because of innovations in the manipulation of mouse genomes. This shift has affected certain research fields, particularly the study of drug abuse and addiction, where behavioral tasks are often too complex for mice to perform. That's led to a slowdown in research aimed at revealing the genetics thought underlie drug abuse-related behaviors. <\/p>\n \"The odds of permanently recovering from drug addiction are low and there is currently very little understanding of why that is,\" Palmer said. \"With an animal system, we have a powerful advantage in that once we've found a genetic location or pathway, we can easily manipulate the gene and measure the resulting effects. The use of rats is critical because many of the behaviors we will study have proven difficult or impossible to adapt for mice.\" <\/p>\n A rat revival <\/p>\n To shed light on the genetics behind complex traits such as drug abuse behavior, the researchers will utilize genome-wide association studies (GWAS) an examination of the entire genomes of different individuals to reveal genetic variants linked with particular traits. Research groups around the country will perform experiments exploring separate behaviors, and send samples to UChicago for genetic analysis. This allows the center to study the genetics of multiple aspects of drug abuse efficiently and at a much more rapid pace than previously possible. <\/p>\n While most animal studies use almost genetically identical subjects, GWAS studies require large numbers of unrelated individuals. The center will support a comprehensive breeding program that provides researchers with a unique population of rats that have been bred to maintain as much genetic diversity as possible. Studies will be performed on both male and female rats to explore the relationship between gender, drug abuse behavior and genetics. <\/p>\n <\/p>\n View original post here: PUBLIC RELEASE DATE: 9-Oct-2014 Contact: Kevin Jiang kevin.jiang@uchospitals.edu<\/a> 773-795-5227 University of Chicago Medical Center @UChicagoMed The National Institute on Drug Abuse (NIDA) has awarded the University of Chicago a $12 million, five year grant to establish a national Center of Excellence to study drug abuse-associated behaviors by conducting research with rats.
