In the article by Zhang and colleagues on the role of COX-2 in TPA-induced cell transformation in the January 2008 issue of Molecular Cancer Research, Chuanshu Huang's affiliation was incorrect. It is Nelson Institute of Environmental Medicine, New York University School of Medicine, New York, NY.

Errors were also found in the β-actin bands of Figures 4E and 6F and the cropped bands of COX-2 and β-actin in Figure 2D. The corrected figures appear here:

Zhang D, Li J, Song L, Ouyang W, Gao J, Huang C. A JNK1/AP-1-dependent, COX-2 induction is implicated in 12-O-tetradecanoylphorbol-13-acetate-induced cell transformation through regulating cell cycle progression. Mol Cancer Res 2008;6:165–74.
