Musical figures: PNAS paper corrected with version of “intentionally contrived and falsified” Nature figure
One of the two corrections recommended by a McGill committee for work by Maya Saleh and colleagues has appeared, in the Proceedings of the National Academy of Sciences (PNAS).
As we reported last month, the committee found that
two figures in [a] Nature paper had been “intentionally contrived and falsified.” One of those figures was duplicated in a PNAS paper, which also contained an image that had incorrectly labeled some proteins.
The committee recommended that both of the papers be corrected, and the PNAS correction for “Confinement of caspase-12 proteolytic activity to autoprocessing” reads as follows:
The authors note that Fig. 6 appeared incorrectly. There was an error in the alignment of the molecular mass markers, and minor adjustments have been made to the assignment of caspase-12 bands. The authors also note that the source of the anti-caspase-12 antibody for Fig. 6 was Sigma (clone 14F7). This error does not affect the conclusions of the article. The corrected figure and its corresponding legend appear below:
The figure — available here — appears to be a modified version of Figure 4C in a Nature paper by the same authors, one of the figures that McGill’s investigation committee said was “intentionally contrived and falsified.”
We’ll be keeping an eye on how the group corrects the Nature paper.
