RELEASE DATE: February 24, 2004

Department of Health and Human Services (DHHS)
Notice is hereby given that the Office of Research Integrity (ORI) and the
Assistant Secretary for Health have taken final action in the following case:
Bernd Hoffmann, Ph.D., University of Medicine and Dentistry of New Jersey :
Based on two inquiry/investigation reports from the University of Medicine and
Dentistry of New Jersey (UMDNJ) and additional analysis conducted by ORI in its
oversight review, the U.S. Public Health Service (PHS) found that Bernd
Hoffmann, Ph.D., former Postdoctoral Fellow and Adjunct Assistant Professor,
Department of Pharmacology at UMDNJ, engaged in scientific misconduct in
research supported by National Institutes of Health (NIH) grant 2 R01 GM052309-05.
PHS found that Dr. Hoffmann engaged in scientific misconduct by falsifying
and fabricating research data in a manuscript entitled LIS1/NUDF and CLIP-
170 are required for dynein-mediated vesicle transport on microtubules that
had been submitted to the Journal of Cell Biology (JCB), but was withdrawn
before publication. Specifically, Respondent:
(1) falsified data values on the second line from the bottom of Table
IV; for example, the correct number under Bound in the first column
was only one-third of that shown (325) in the manuscript;
(2) falsified data by erasing a band of approximate molecular weight
15KD from Figure 5A in the manuscript; and
(3) falsified a related movie film available on the Internet by
altering the movement of the vesicles.
PHS also found that Dr. Hoffmann engaged in scientific misconduct by
falsifying and fabricating research data in a published paper entitled
The LIS1-related Protein NUDF of Aspergillus nidulans and its
Interaction Partner NUDE Bind Directly to Specific Subunits of Dynein
and Dynactin and to Alpha- and Gamma- Tubulin that had been published
in the Journal of Biological Chemistry (JBC) at 276:38877-38884, 2001.
Specifically, Respondent:
(1) falsified Figure 5A left, Western blot with the alpha tubulin
antibody for incubated proteins (+E+gamma+alpha); the lower right band
was reused twice in Figure 2A. In Figure 5A, it was used as gamma
tubulin band for the coprecipitation experiment with NUDF-Prot.S and as
NUDE for the coprecipitation experiments with NUDG (CDLC)-Flag;
(2) falsified Figure 5A left, NUDF Western blot with the alpha tubulin
antibody for incubated proteins (+E+gamma+alpha); the lower left band
was reused in Figure 2A as alpha tubulin in the coprecipitation
experiment with NUDF-Prot.S; and
(3) falsified Figure 4A left, NUDF and for the interaction between the
two proteins NUDA and NUDF, pulled out with NUDA-FLAG-agarose, had been
used at several other places such as Figure 5A left, left gamma tubulin
band, Figure 5B left, NUDE band for the interaction E + alpha, and
Figure 5B right, NUDE band for the interaction E + K (ARP1).
Dr. Hoffmann has entered into a Voluntary Exclusion Agreement
(Agreement ) in which he has voluntarily agreed for a period of three
(3) years, beginning on January 30, 2004:
(1) to exclude himself from any contracting or subcontracting with any
agency of the United States Government and from eligibility or
involvement in nonprocurement programs of the United States Government
referred to as covered transactions as defined in the debarment
regulations at 45 C.F.R. Part 76;
(2) to exclude himself from serving in any advisory capacity to PHS
including but not limited to service on any PHS advisory committee,
board, and/or peer review committee, or as a consultant; and
(3) to draft a letter of retraction and send it to ORI along with the
signed Agreement. The draft letter requested the retraction of the JBC
paper published at 276:38877-38884, 2001 and stated that he falsified
and fabricated data in Figures 2A, 4A, 5A, and 5B. Upon ORI approval
of the draft letter, Respondent agreed to send the final retraction
letter to the Editor of JBC.
