Correction

In the January/February 2009 Diffusion article, “Gfi1: Dual Functions as Oncogene and Inducer of Differentation,” we inadvertently referred to only one of two papers that reported the phenotype of Gfi1 KO mice. We apologize for not including the first report of such mice, which was published by Dr. Tarik Möröy’s group: Karsunky H, Zeng H, Schmidt T, Zevnik B, Kluge R, Schmid KW, Dührsen U, and Möröy T. Inflammatory reactions and severe neutropenia in mice lacking the transcriptional repressor Gfi1. Nature Genetics. 2002;30:295-300.
