Case Summary: Wang, Ya

Ya Wang, M.D., Ph.D., Emory University: Based on the report of an inquiry conducted by Emory University (EU) and additional analysis conducted by the Office of Research Integrity (ORI) in its oversight review, ORI found that Ya Wang, M.D., Ph.D. (Respondent), retired Professor and Director, Division of Experimental Radiation Oncology, Department of Radiation Oncology, Winship Cancer Institute, EU, engaged in research misconduct in research supported by U.S. Public Health Service (PHS) funds, specifically National Cancer Institute (NCI), National Institutes of Health (NIH), grants P30 CA138292 and R01 CA186129 and National Institute of General Medical Sciences (NIGMS), NIH, grant R01 GM080771.

Respondent neither admits nor denies ORI’s findings of research misconduct. The settlement is not an admission of liability on the part of the Respondent. The parties entered into a Voluntary Exclusion Agreement to conclude this matter without further expenditure of time, finances, or other resources.

ORI found that Respondent engaged in research misconduct by knowingly, intentionally, and/or recklessly falsifying data that were included in the following one (1) PHS grant application and six (6) published papers:

ORI found that respondent knowingly, intentionally, and/or recklessly falsified protein immunoblot data by reusing and relabeling the same images to represent different experimental conditions in mammalian tissue culture models of DNA damage and repair in eighteen (18) figure panels in eleven (11) figures in one (1) grant application and six (6) published papers.

Specifically:

  • western blot images for total protein expression in distinct transgenic mouse cell lines were falsified by reusing immunoblot bands and relabeling them to represent different experiments in eleven (11) figure panels in two (2) papers, including:
     
    • Figure 3D in J Biol Chem. 2017, representing β-actin expression (left side panel) in wildtype (WT), microRNA-21 (miR-21) knock-in, and miR-21-/- mouse embryonic fibroblast (MEF) cells exposed to irradiation
