‘Down‐regulation of Jagged‐1 induces cell growth inhibition and S phase arrest in prostate cancer cells’ by Zhang, Y., Wang, Z., Ahmed, F., Banerjee, S., Li, Y. and Sarkar, F. H.

The above article, published online on 5 July 2006, in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor‐in‐Chief, Professor Peter Lichter, and Wiley Periodicals, Inc. A university investigation involving the second and the corresponding author determined that histone bands in Fig. 4 in this paper were manipulated and that β‐actin bands in Fig. 1C were duplicated from another publication. Therefore, the authors are retracting the paper in its entirety although they maintain that these issues did not affect the major conclusions. They apologize for any inconvenience this may have caused.
