USC Neuroscientists to Map Gene Expression

Two USC neuroscientists have been awarded nearly $9 million in American Recovery and Reinvestment Act funds to map how genes are expressed in different regions of the human brain throughout development.
The two-year Grand Opportunity grant, funded through the National Institutes of Mental Health, will allow researchers to use DNA sequencing and profiling technologies to create an atlas of when and where thousands of genes are expressed during key periods of development. The findings will be freely accessible to scientists worldwide and provide a foundation for discovering the origins of mental disorders.
James A. Knowles, professor of psychiatry at the Keck School of Medicine of USC, and Pat Levitt, director of the Zilkha Neurogenetic Institute at the Keck School of Medicine, will lead the project in collaboration with researchers at Yale University and the Allen Institute for Brain Science in Seattle, Wash.
Ewa Deelman of the USC Information Sciences Institute will oversee workflow technologies to support RNA sequencing and Ann Chervenak will handle data management.
“This project will allow us to document which individual genes and sets of genes are turned on and off in different brain regions through the whole developmental time period,” said Knowles, the principal investigator on the project. “This information is essential for understanding normal and abnormal brain development.”
Mental disorders such as autism and schizophrenia are increasingly recognized as brain disorders that have their origins during development. However, relatively little is currently known about how specific genes regulate human brain development, Knowles noted.
“Breaking through the mysteries of the developing human brain and the origins of mental illnesses requires a very large, collaborative effort,” co-principal investigator Levitt said. “We are so pleased to be part of an esteemed group of scientists that will produce more information on the human brain than ever before. This will lead to new breakthroughs in determining disease risk and prevention.”
Researchers at USC and partner institutions will sequence the genomes from hundreds of brain samples in order to create a three-dimensional, Web-based model that can be used by scientists all over the world as a basis for future neuroscience research.
“This will provide investigators with a fantastically rich resource for future research,” Knowles said.
The purpose of the National Institutes of Health Research and Research Infrastructure Grand Opportunities program is to support high impact ideas that lay the foundation for new fields of investigation. The initiative is one of several being offered to help fulfill the goals of the American Recovery and Reinvestment Act of 2009 to help stimulate the economy through support of biomedical and behavioral research.

Los Angeles Times featured the USC Rossier School’s centennial gala, which took place February 1. USC President Steven B. Sample was honored with the Global Education Leadership Award, and USC alumna Cindy McCain was honored with the Dean’s Alumni Achievement Award. “It’s rare for someone who’s lived as long as I have in politics with my husband to be speechless, but I truly am,” McCain said. Mayor Antonio Villaraigosa introduced Sample, recounting his work in raising USC’s stature globally, being open to international students, and understanding USC’s position in Los Angeles as “the gateway to Asia and Latin America.” Nearly 350 people attended the event, including Sen. John McCain; Ed Roski, chairman of the USC Board of Trustees; Barbara and Roger Rossier, for whom the Rossier School is named; John Katzman, Princeton Review founder and benefactor of an endowed chair at the Rossier School; and alumni and longtime USC supporters Debbie and J. Terrence Lanni and Verna Dauterive.
The Chronicle of Higher Education included USC in a chart on international fundraising by higher education institutions. USC has received $2.9 million from international philanthropic funds, and is estimated to have more than 6,000 foreign alumni, the story stated.
The Chronicle of Higher Education featured Paul Debevec of USC’s Institute for Creative Technologies, who won an Academy Award for co-creating a light stage capture device and image-based facial rendering system that has been used in movies like “Avatar.” The award will be presented at a formal dinner on February 20, the story noted. Asked whether the technology could be applied to education, Debevec said: “Absolutely, yes. Maybe there’s a little rendering of a chemistry professor at the side of the screen who smiles at you when you get the question right and frowns when you get the question wrong. [In perhaps 10 years] that computer might, through its Web cam, look back at you, see where you’re looking on the screen, see how engaged you are, and actually adapt itself to trying to teach you in the way that it seems to be working the best. Just like one-on-one tutoring.”
The Chronicle of Higher Education featured linguist Paul Frommer of the USC Marshall School, who created the language Na’vi for the Golden Globe-winning movie “Avatar.” “Doing this kind of work as an academic is not going to advance your research reputation. It’s not going to result in publications in peer-reviewed journals,” Frommer said. “But it just may push the world forward in the way it’s turning on young people to the wonders of language”
Los Angeles Times reported that the 22nd annual USC Libraries Scripter Award was given to “Up in the Air” novelist Walter Kirn and to USC alumnus Jason Reitman and Shelton Turner, who adapted Kirn’s book for the screen. Los Angeles Times ran a second story about the Scripter Award.
