Following the publication of this article, which was concerned with the expression of phosphorylated epidermal growth factor receptor (pEGFR) and cyclin D1 activation independently of the expression levels of cyclo-oxygenase-2, an interested reader drew to our attention apparent anomalies associated with the western blot data shown in Fig. 2C. Following an internal investigation at the New York University School of Medicine, we were requested to produce the original film, or the scan of the image of the film, for verification. Unfortunately, we were unable to provide the original film or scanned image to disprove the allegation, since the original pEGFR image could not be found. Therefore, the Investigation Committee recommended that this article be retracted, and we are withdrawing the article in line with the request. All the authors agree to the retraction of this paper. We sincerely regret any inconvenience this has caused. [the original article was published in the International Journal of Oncology 40: 13-20, 2012; DOI: 10.3892/ijo.2011.1211].
