This article (1) has been retracted at the request of the editors. The editors were made aware of concerns regarding potential manipulation of data in a number of figures: the 8-hour DR5 Western blot band appears to have been electronically inserted into Fig. 3A; it appears that the same β-actin Western blot bands were used in Figs. 3C, 5A, and 5B; the background of the DR4 Western blot panel appears to have been electronically manipulated in Fig. 3D; the background of the DR5 Western blot panel appears to have been electronically manipulated in Fig. 4A; and lanes 2 and 3 of the Bcl2 Western blot appear to have been electronically inserted into Fig. 6B. In response to a query by the editors, the corresponding author, B. Aggarwal, stated that these data are correct, but did not provide the original data.
A copy of this Retraction Notice was sent to the last known email addresses for all four authors. One author (S. Prasad) did not agree to the retraction; the three remaining authors (V.R. Yadav, J. Ravindran, and B.B. Aggarwal) did not respond.
