The authors wish to retract the article titled “NRH:Quinone Oxidoreductase 2 and NAD(P)H:Quinone Oxidoreductase 1 Protect Tumor Suppressor p53 against 20S Proteasomal Degradation Leading to Stabilization and Activation of p53,” which was published in the June 1, 2007, issue of Cancer Research (1). As a result of an error, the p53 and NQO2 panels in Fig. 6A were reused from Fig. 3B of the article titled “Lower induction of p53 and decreased apoptosis in NQO1-null mice lead to increased sensitivity to chemical-induced skin carcinogenesis” by Iskander and colleagues (2).
Two of the four authors agreed to this Retraction. Attempts on the part of the journal office to contact Xing Gong and Labanyamoy Kole were unsuccessful.
