Scientists Study Mutant Mice to Uncover Secrets of Longevity

A scientist at Southern Illinois University's School of Medicine will share in an $8.6 million federal grant to continue his study of aging and longevity.

The grant announced Tuesday designates Andrzej Bartke as the lead researcher of a team that includes scientists at the Mayo Clinic, the University of Michigan, Ohio University and the University of Texas Health Science Center.

Bartke says the team will use a type of mutant mice that lives longer to look at how the aging process is affected by fat cells, genes and insulin.

Bartke has been a physiologist at the medical school's Springfield campus since 2002. About $2.8 million of the grant money will be used by Bartke and his researchers in Springfield.
