Retraction: Inactivation of the Quinone Oxidoreductases NQO1 and NQO2 Strongly Elevates the Incidence and Multiplicity of Chemically Induced Skin Tumors

This article (1) has been retracted at the request of the editors. Following an institutional investigation by the University of Maryland, Baltimore (Baltimore, MD), it was determined that data were falsified to generate the graphs presented in Figs. 2C and D and 3. As a result of these findings, the institution recommended retraction and, upon internal review, the editors agreed with this recommendation.

A copy of this Retraction Notice was sent to the last known email address for one of the three authors. One author (A.K. Jaiswal) did not respond; the two remaining authors (J. Shen and R.J. Barrios) could not be located.
