In Figure 4A on page 356, panels CLL #5 and CLL #6 contain western blot images that are duplicated. The authors believe that an inadvertent mistake occurred in the preparation of revisions for the published version of Figure 4. Because it has proved impossible to find the original data and blots, they performed the same experiment described in the article, using different chronic lymphocytic leukemia (CLL) patient samples. The new data are consistent with the previous findings and provide evidence for the reproducibility of the research. A figure and table showing the data from the new experiment are contained in an updated supplemental file available in the online version of this erratum, and the figure is also shown below.
The authors deeply regret this error and state that this correction does not affect the original conclusions of the study.
Editors’ note: The Blood Editors were notified of the error in Figure 4A by The Ohio State University. Author Carlo M. Croce provided uncropped and unedited versions of the new figure.
