Office of the Secretary, HHS.
Notice is hereby given that the Office of Research Integrity (ORI) has taken final action in the following case:
Li Chen, Ph.D., Mount Sinai School of Medicine: Based on evidence and findings of an investigation report by Mount Sinai School of Medicine (MSSM) transmitted to the United States Department of Health and Human Services (HHS), Office of Research Integrity (ORI), in April 2010 and additional analysis conducted by ORI in its oversight review, ORI found that Dr. Li Chen, former Postdoctoral Fellow, Department of Gene and Cell Medicine, MSSM, engaged in research misconduct in research that was supported by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), National Institutes of Health (NIH), grant R01 DK062972 and National Start Printed Page 22974Institute of General Medical Sciences (NIGMS), NIH, grant P20 GM075019 and was submitted in grant applications R01 DK074695 and R01 DK083286 to NIDDK, NIH, P20 GM075019 to NIGMS, NIH, and R01 NS062054 to the National Institute of Neurological Disorders and Stroke (NINDS), NIH.
ORI found that the Respondent intentionally, knowingly, and recklessly fabricated and falsified data reported in four (4) publications, one (1) submitted manuscript, and four (4) grant applications:

The Respondent fabricated figures reporting the chromosomal locations of integration sites, fabricated data reporting the use of polymerase chain reaction (PCR) to determine integration frequencies, falsified data representing the detection of chromosomal translocations in human cells, and fabricated figures by falsely reporting the results of High-Performance Liquid Chromatography (HPLC) assays. The Respondent also falsified experimental data for LacZ stained liver sections and for hematoxylin and eosin (H&E) stained liver sections.
Specifically, ORI finds by a preponderance of the evidence that the Respondent engaged in misconduct in science and research misconduct by intentionally, knowingly, and recklessly:
1. fabricating and/or falsifying nineteen (19) figures by falsely reporting that phenylketonuria (PKU) gene therapy experiments were successfully completed, when the available evidence shows the experiments were not performed; specifically the Respondent:
(a) fabricated figures where DNA sequencing was purportedly used to identify the chromosomal locations of integration sites for the PAH gene in mouse and human cells, reported in seven (7) figures:
- PNAS 2005, Figure 2A
- HGT 2008, Figures 3b and 3c
- R01 NS062054, Figures 3 and 20
- R01 DK074695, Figure 6
- R01 DK083286, Figure 17
- P20 GM075019, Figure 4
(b) fabricated data purportedly representing the use of PCR to determine integration frequencies for the phenylalanine hydroxylase (PAH) gene and the secreted embryonic alkaline phosphatase (SEAP) reporter gene, in mouse and human cells, reported in eleven (11) figures:
- PNAS 2005, Figures 2C and 3B
- Mol. Ther. June 2007, Figures 2a and 5a
- Mol. Ther. Oct. 2007, Figures 2d and 5a
- HGT 2008, Figure 4
- R01 NS062054, Figures 4b and 10a
- R01 DK074695, Figure 7b
- R01 DK083286, Figure 2b
(c) falsified figures representing the detection of chromosomal tranlocations in human cells, purportedly determined by PCR in two (2) figures:
- HGT 2008, Figure 5a
- R01 NS062054, Figure 21a
2. fabricating the results of HPLC assays to show generally lowered blood levels of phenylalanine after PKU gene therapy and to show liver levels of BH4 when the Respondent did not have the HPLC data needed to support those claims; specifically the Respondent:
(a) fabricated serum phenylalanine graphs in:
- PNAS 2005, Figure 4B; this false data also is presented in R01 DK074695, Figure 10b
- Mol. Ther. June 2007, Figure 1a; this false data also is presented in R01 DK074695, Figure 11
- R01 DK083286, Figure 3; this false data also is presented in Mol. Ther. June 2007, Figure 3, and R01 NS062054, Figure 7
- Mol. Ther. Oct. 2007, Figure 4a; this false data also is presented in R01 NS062054, Figure 9a
- PNAS 2008 manuscript, Figure 4
(b) fabricated graphs for BH4 levels in:
- Mol. Ther. June 2007, Figure 5c; this false data also is presented in R01 NS062054, Figure 8c
3. falsely reporting the results of LacZ stained liver sections by reusing and relabeling an image and claiming that it represents different experiments; specifically, the same image was used to represent mice treated with a nanoplex gene delivery system in R01 NS062054, Figure 14b (right panel), and also to represent a wholly different experiment for mice treated with 10 injections of the phiBT1 integrase system alone in R01 NS062054, Figure 4c (right panel), and Mol. Ther. Oct. 2007, Figure 2b (D panel)
4. falsely reporting the results of H&E stained liver sections in R01 NS062054, Figure 6, by using the identical image to represent four (4) different experimental treatments of H&E stained liver sections; specifically the Respondent reused and relabeled one image to represent liver sections from mice that received either 1 or 10 injections, with or without the phiBT1 integrase plasmid.
The Respondent failed to take responsibility for the fabrication and falsification described in ORI's findings.
