The research, conducted by a team of scientists led by biochemist Hector F. DeLuca at the University of Wisconsin-Madison, was reported this week (Sept. 30) in the Proceedings of the National Academy of Sciences (PNAS), a leading scientific journal.

By subtracting a single gene from the genome of a mouse, scientists have created an animal that can eat a rich, high-fat diet without adding weight or risking the complications of diabetes, according to a new study published this week.

Writing in the online editions of the Proceedings of the National Academy of Sciences (PNAS), James M. Ntambi, a professor of biochemistry and of nutritional sciences at the University of Wisconsin-Madison and colleagues report that mice lacking a gene known as SCD-1 can eat a rich high-fat diet and avoid the consequences of fat deposition and excess...
