In the article on the effects of IFN-α plus bortezomib in bladder cancer in the December 2006 issue (1), one of the immunohistochemical images in the UM-UC5 panels (left side of Fig. 7D) was inadvertently duplicated. Because therapy had no significant effects on VEGF expression in these tumors, the error had no impact on the conclusions presented in the study. The correct Fig. 7D appears below.
