For the article “Live-specific deletion of negative regulator Pten results in fatty liver and insulin hypersensitivity,” by Bangyan Stiles, Ying Wang, Andreas Stahl, Sara Bassilian, W. Paul Lee, Yoon-Jung Kim, Robert Sherwin, Sherin Devaskar, Ralf Lesche, Mark A. Magnuson, and Hong Wu, which appeared in issue 7, February 17, 2004, of Proc. Natl. Acad. Sci. USA (101, 2082-2087; first published February 9, 2004; 10.1073/pnas.0308617100), due to a printer's error, the title appeared incorrectly and should read “Liver-specific deletion of negative regulator Pten results in fatty liver and insulin hypersensitivity.” The online version has been corrected.
