Retraction.

Retraction: "Genistein enhances the effect of epidermal growth factor receptor tyrosine kinase inhibitors and inhibits nuclear factor kappa B in nonsmall cell lung cancer cell lines" by Gadgeel SM, Ali S, Philip PA, Wozniak A, Sarkar FH. The above article, published in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement amongst the journal Editor in Chief, Fadlo R. Khuri; Wiley Periodicals, Inc.; and the American Cancer Society following an investigation by Wayne State University into the research activities of the second and last authors. The investigation found that the Western blot images of Figures 4A, 4B, and 4C were re-ordered and manipulated to misrepresent the results. The investigation committee concluded that this undermined the scientific basis of the publication, that no credible replacement data were available, and advised that the publication should be retracted.
