There’s been a 10th retraction from two former postdocs at a UT-Southwestern cancer research center who were sanctioned by the Office of Research Integrity (ORI) last September, in part due to observations and comments from Retraction Watch readers.
It’s a 2008 Cancer Letters paper, “Methylation of apoptosis related genes in the pathogenesis and prognosis of prostate cancer,” retracted at the request of Makoto Suzuki, the first author who has claimed responsibility for falsifying data in this and five other papers.
You can see our full coverage of the events here, including the role RW readers played in uncovering the misconduct.
Suzuki, now at Kumamoto University Hospital in Japan, conducted the misconduct while a postdoc in the lab of Adi Gazdar at UT-Southwestern in Dallas. Around the same time, another postdoc in the same laboratory, Takao Takahashi, falsified data in four papers.
In this case, the paper was pulled for falsification of a western blot of the methylation of four genes in prostate cancer. The full retraction notice reads:
This article has been retracted at the request of the first Author, who accepts responsibility. Following an internal review at the UT Southwestern Medical Center in Dallas, evidence has been found of improper manipulation and duplication of Figure 1 in this article.
The ORI delivered their ruling on Suzuki, citing falsification in this paper, in September 2014, but the paper was only now retracted. The paper has been cited 42 times, according to Thomson Scientific’s Web of Knowledge.
We’ve reached out to Suzuki and Cancer Letters editor-in-chief Manfred Schwab at Deutsches Krebsforschungszentrum (DKFZ) in Germany for any additional details, and will update if we hear back.
