Expression of Concern: ΔNp73, A Dominant-Negative Inhibitor of Wild-type p53 and TAp73, Is Up-regulated in Human Tumors

The authors of this paper notified the Journal of Experimental Medicine of an error made during Figure 3 C assembly.The same blot was used for 14-3-3 and p21 in lanes 6 and 7, making it unclear whether the data represent 14-3-3 or p21.Due to the time elapsed since publication, the authors regret that they no longer have access to the original data.Consequently, JEM and the authors are unable to verify the validity of Figure 3 C.
