Now, Hanna has responded in the comments of the PubPeer entries for a number of papers. He has also posted a number of PDFs, including his PhD thesis, and correspondence with scientists who have been critical of his work.
One of Hanna’s comments on PubPeer is a summary of the issues with his Blood paper on PubPeer, blaming the figure errors on “medical trainees” who did the word while he was away at Mount Sinai. Here’s his explanation:
As we wrote, this will be corrected and explained in detail with the other issues very soon.
In brief, Figures 4,5,6 and 7 in the blood Manuscript were conducted and assembled by medical trainees (M.D., S.H. and N.W.) based on my instructions while I was away for 6 months at Mount Sinai NYC (end of 2004) for a medical student exchange program. Unfortunately, this led to mistakes in data presentation and use of wrong files, which i still take full responsibility for as their supervisor and first author of the paper. This also relates to mistakes in my 2004 JCI and JI papers, revised during the same period (Corrections for the latter have been submitted and accepted).
Fortunately, as the TAP2 deficient patients are still healthy due to the dedicated care of their physician, and as we have all ethical approvals still in place, we have repeated these experiments again in order to resolve this. While we have more work to do, all the results we have obtained so far maintain the validity of our claims and conclusions (as expected from a stable genetic mutation carrying cells, but always comforting of course:)), and we will approach Blood journal with a request for correction soon once we conclude conducting our final tests.
I apologize for the mistakes, but my main goal is to correct the scientific record and re-check the validity of the reported findings, and it clearly remains unchanged based on the data we have obtained so far.
It seems to be becoming more common for high-profile scientists to jump into the fray of anonymous post-publication review, which we think is a good thing. We look forward to the official corrections.
