Chainsaw Chang and Soo Not Ok Lee

Smut Clyde celebrates here a highly successful US cancer research lab at University of Rochester. Its head is Chawnshang "Chainsaw" Chang, and his most productive scientist is Soo "Not" Ok Lee.

The University of Rochester in USA is where the mitochondria researcher and a famous whistleblower Paul S Brookes works. Brookes used to run a short-lived website called science-fraud.org, where he anonymously exposed dishonest scientists and their data manipulations, up until in 2013 his identity was exposed and the cheaters sued him. In 2012, Paul Brookes even published a blog post about his faculty colleague and head of the George Wipple Lab, Chawnshang Chang, who is affectionately called by his Rochester colleagues “Chainsaw”.

Brookes posted his analysis of manipulated data in Chainsaw’s papers on his now deleted website, under the headline “The ugly truth behind university PR hoopla“, and wrote:

“So, to summarize, the science behind this newly patented prostate cancer fighting wonder drug appears to be a little bit shady. My source on this story indicates that he’s written the University, the company involved, and the journals, but so far only the University has responded (with a generic “we’ll look into it” email).”

Chawnshang’s wonder drug, proudly advertised by University of Rochester, was as Brookes wrote

“a derivative of curcumin, an ingredient in spicy foods. As readers of this blog may already be aware, curcumin itself has come under fire recently, following the investigations into research misconduct by Bharat Aggarwal of MD Anderson Cancer Center.”

The blog post is long gone since, together with the entire website, but here are screenshots. In summer 2012, Brookes created two files, describing data manipulations in papers by Chainsaw Chang, and by his mentee and now Taipeh Medical University professor, Yu-Jia Chang.

These were the two files Brookes shared with his university:

Screenshots of Brookes’ now deleted blog post from 2013

Apparently there was an investigation in 2012 which however did not achieve much. In 2016, Brookes got knowledge of even more irregularities in a fresh paper from Chainsaw’s lab, and reported these also to the university authorities. The authors were asked to explain, the following images visualise the problems and authors’ explanations:

“After we checked carefully, we found the mistake was in Fig.4F”
As submitted by Brookes in 2016
“We also have the repeated original data”
Authors were asked to explain
“My notebook pictures”

The full PowerPoint file submitted by the authors in their defence is available here. A Corrigendum was issued by the journal already in November 2016:

“Upon checking the figure in question, we found that, by oversight, during preparation of these multiple set of figure panels, some of the images that had been included were incorrect.”

Not much happened since, Chawnshang only got wealthier and stronger. His George Wipple Lab mostly employs Chinese or Koreans, like Chainsaw’s right-hand-woman, Soo Ok Lee. This creates certain power structures inside the lab which every university should actually avoid. Soo Not Ok Lee is highly productive and able to generate oodles of papers using nothing but Photoshop, so it seems. Chainsaw also seems not to mind how the papers in his lab are made, as long as they bring in cash into his own pocket.

A certain whistleblower contacted Brookes recently, about new evidence he published on PubPeer. On 4 December 2019, “John Smith” wrote in an email:

In this July, I reported to URMC compliance office about many serious data falsifications, generated by Soo Ok Lee’s lab at URMC, appearing in 13 research articles across multiple journals. Too many Western blot bands and microscopic images were found duplicated or inappropriately manipulated to represent data for different experiments in her papers. I have  revealed those data falsifications in the following PubPeer webpages.
Although recently URMC Dean finally replied that they will investigate this case, I still worry that Lee is able to continue fabricating data to do erratum because URMC still allows Lee working in her lab since I reported this case in July.

The attached PubPeer record for Soo Not OK Lee exploded since, thanks to the efforts of Elisabeth Bik and others, also many new papers signed by Chainsaw were flagged. I approached the University of Rochester and its School of Medicine for a comment, and got this statement from the Vice-Dean for Research, Steve Dewhurst, regarding the failed 2012 investigation:

we are aware of correspondence between the University and the editor of at least one major scientific journal at that time, related to concerns of the kind you have referenced.  The outcome of that correspondence was determined by the journal and its editor.

Dewhurst then clarified in a follow-up email:

The University has consistently addressed matters of this kind, and does not take the view that authors should sort it out themselves.   We have a policy and it is followed.  We do not, however, publicly share the details of our confidential internal processes/investigations […] the University communicated directly with the journal editor

As for the current growing PubPeer evidence of currently 45 papers, co-authored by Chainsaw, his henchwoman Not Ok Lee and the other one of the two George Wipple Lab investigators, Shu-Yuan Yeh, Dewhurst said this in his two emails:

We are in the process of reviewing the concerns raised about the additional publications, and the specific authors that you have referenced […]

Please be assured that we share your concern about the integrity of the scientific record and any allegations of fraudulent data have been or will be subject to the University’s review.

Update 12.09.2020 UR Medicine now investigated 15 papers by Soo Ok Lee and her coauthor Yuhchyau Chen, and decreed:

there was no finding of misconduct associated with any of the 15 articles subject to the Investigation, but there were errors noted in 13 articles.

Full letter by UR Medicine is quoted at the end, but if you are in a hurry:

But now, Smut Clyde‘s take on the Rochester affair. Smut even made a table of 45 papers by Chainsaw Chang and Soo Not OK Lee, the list is available here.


The Chawnshang Redemption

By Smut Clyde

Back in the days, the pinnacle of the bachelor professional life-style (if 1980s Esquire advertising was to be believed) was a modular surround-sound HiFi system. That is, a chrome scaffold holding tape-deck, FM receiver, pre-amp, amplifier and graphic equaliser as separate components, stacked vertically so the discriminating audiophile could slide any one out to replace it with an upgrade, between sips of Chivas Regal.

What evoked this flashback from a simpler time was a tower of Western-Blotted protein slices, presented as Figure 5(a) of Shen et al (2017) [14] with the implicit claim that they all came from a single experiment, with results comparable across columns and rows.

The problem is that two of those slices reappeared in Fig 4A of Zhu et al (2018) [17], in different company and identified as different proteins (though with the same column identifications). This helpful diagram is based on one by ‘Parapolystichum Boivinii‘.

Moreover, as ‘Yponomeuta Spodocrossusnoted, this second stack of slices was dismantled in turn, its constituents becoming building blocks for Fig 6A of Xu et al (2018a) [19] and again for Fig 5(f) of Chen et al (2019a) [21]. If the HiFi metaphor doesn’t appeal, think of the slices as blocks in a Jenga game instead.

A second helpful diagram from Parapolystichum Boivinii links the same stack from [14], through different pathways of protein-band repurposing, to Fig 4G of [17], and to 3B and 4B of Xu et al (2018b) [20]. The two diagrams could probably be combined but that sounds like work. It would be complicated by the third link from Fig 5A (and 2D) of [14] to 3B of Shen et al (2018) [18].

One gains the general impression that researchers in the Department of Radiation Oncology (University of Rochester School of Medicine and Dentistry) are not obsessive about the exact nature or provenance of WB slices, and keep them hugger-mugger and higgledy-piggledy in a drawer marked “Collage Supplies”. Thus they appear in a succession of temporary context-specific coalitions rather than as persistent legacies of individual experiments.

When these concerns were raised in mid-2019, Soo Ok Lee (Research Associate Professor in the Department) took the trouble to respond, promising to investigate and amend the papers if necessary, for some reason using the email account of co-author Peter Keng (co-author and Professor Emeritus there). After that admirable and encouraging beginning, the group has observed nine months of radio silence, and one can only hope that their legal advisers are not charging by the hour.

By now the more astute readers know to expect another unsystematic stroll through the annals of the PubPeer post-publication peer-review system. Yes indeed, other trails of protein recycling criss-cross the entries, radiating out from Yang et al (2017) [16] to Yang et al (2016) [11] and Zhang et al (2017) [15]. Meeting other concerns along the way.

However, this record of reuse is not restricted to Western-Blot high-rise apartment blocks. We encounter cell spheroids with more than one identity (though there is no evidence that they held false passports as preparation for fleeing the country to evade arrests): Figures 5D from Lee et al (2016) [12] and 2(c) from Chen et al (2015) [7]…

Another bridge between [7] and [12] are these immunofluorescent cells of ambiguous origin.

While [21] leads to Chen et al (2019b) [22].

The vast and cool and unsympathetic intellects who contribute to PubPeer (only sporadically credited here) have scrutinised the author of interest’s CV back to 2002/2003, when she was at the Department of Urology and Cancer Institute, University of Pittsburgh Medical Center. For instance, a Western Blot loading control recurred in three papers: DeMiguel et al (2002) [1], Lee et al (2003a) [2], Lee et al (2003b) [3]. The ultimate author, i.e. the Principal Investigator if the usual conventions of biomed authorship were observed, was Allen C. Gao. Gao was also the only author in common when the same loading-control band resurfaced in Chun et al (2007).

The period 2012-2015 in Dr Lee’s CV was productive, with six papers coming to PubPeer attention, beginning with Tian et al (2012) [6].

Corrections have been provided for most and others may be on the way.

#2 Chiung-Kuei Huang commented 7 days ago
 

I dwell on this section of the chronology as it provides an entry-point to the oeuvre of Chawnshang ‘Chainsaw’ Chang (or Zhang Chuanxiang in the old-fashioned way of transliterating 张传祥). Now Chang is (or was) an apex predator a dominant figure in the Rochester University academic ecosystem: Director of the George H. Whipple Lab for Cancer Research, and of his own laboratory nested therein, on faculty as well at the Wilmot Cancer Institute, researching the oncogenesis and treatment of prostate cancer. This topic exerts great fascination for old, wealthy men, whose interests are so easily confounded with the priorities of oncology research.

Prof. Chang holds a string of patents for a synthetic curcumin-based molecule ASC-J9 — or more precisely, one patent has been registered in a lot of countries — and founded Androscience Corporation to commercialise these patents. Though six years have passed since the most recent communiqué from Androscience. Any therapeutic success in prostate cancer trials has not been proclaimed as loudly as one might expect and the company’s activities have focused on searching for any condition that Chang’s rejigged curcumin might potentially treat: bladder cancer or liver cancer or muscular dystrophy or acne.

In further signs of Prof. Chang’s eminence, he was recruited in 2010 to Taiwan to head the Sex Hormone Research Center at China Medical University Hospital. He was concurrently recruited to Tianjin Medical University in mainland China to head the less-modestly-titled Chawnsung Chang Sex Hormone Research Center. Some sources are under the impression that the former institution is also eponymous.

Nor should we forget the Chawnshang Chang Liver Cancer Center in Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, Hangzhou. Nor the titles and funding conferred upon Chang under the Thousand-Talents scheme — first in 2011 at a Tianjin regional level, then at the national level in 2012.

So if I were in Chang’s shoes lab-coat, with a CV as illustrious as his, three Oncotarget papers would not be my first choice as career high-points to build my academic webpage around:

Journal Articles

[8]

The 1000-Talents program is intended to grow Chinese scientific capabilities in many ways, from luring expatriate scholars back home (temporarily if not permanently), and ensuring that Chinese doctorates are immersed in world-class research environments, to facilitating the theft of intellectual property — though suspicions along those last lines are undoubtedly fueled by political xenophobia. In a sad postscript, Prof. Chang was accused in late 2014 of exploiting his Chinese colleagues and visiting students, treating them with disrespect:

He has multiple NIH research funds in the United States and experiments at the University of Rochester The room has 20-30 students for a long time. He is a Taiwanese, and he is extremely unfriendly to students from the mainland and squeezes their sweat and blood with extremely low wages. But for so many years, he has made crazy money in China. In addition to his full-time job in the United States and his position in Taiwan, he has deceived the Tianjin Medical University Thousand Talents Program at home, a Yangtze River scholar, a lecturer professor at the Shao Run Hospital in Hangzhou, and a visiting professor at Sun Yat-sen University. He often brags about how much he earns on the mainland. Such academic scammers should be exposed, hoping that relevant departments will find out how he, a full-time professor in the United States, fulfilled the obligations of the Thousand Talents Program, Yangtze River scholars, and recovered losses for the country.

If true, this could have contributed to a laboratory climate of No-fucks-to-give sloppiness — as if minor authors lacked the motivation to be meticulous in assembling their diagrams. In the Chang-specific PubPeer threads (Soo Ok Lee-free) we find (for example) duplicated WBs…

Chen et al (2015) [7]

Overlapping immunohistochemistry-stained tissue slices…

Altuwaijri et al (2009) [5]

and overlapping Migration / Invasion matrigel assays.

Was no-one checking their work? I hasten to note that these stains on the departmental escutcheon go back before the 1000-Talent recognition, with 2002 as the earliest manifestation.

In less 15 min all previous members related to Soolee all line back!! We are in one family”

Anyway, to his credit, Prof. Chang is determined to see any minor errors made good. When the queries at PubPeer targeted his collaborations with Soo Ok Lee he circulated an email among past and present colleagues, requesting their assistance while appealing to their sense of familial loyalty. The word “omerta” did not occur.

Chiung-Kuei Huang, a George Whipple Lab alumnus (now at Brown University R.I.) is coordinating the responses to PubPeer, responding on the authors’ behalf when he was not a co-author himself.

I am not sure of the current status of the C. C. Sex Hormone Research centre, which no longer features in the academic affiliations of researchers from Tianjin Medical University. Fortunately the Wayback Machine preserved copies of those triumphant TMU press releases about luring Chang into residence, or the 1000-Talent grant, as the originals are no longer extant.

Sometimes those audiophile sound-systems went completely overboard.

Update 12.09.2020

A letter from University of Rochester Medical Center to the journal Oncotarget has been leaked, dated 8 September 2020. UR Medicine investigated 15 papers by Soo Ok Lee and her coauthor Yuhchyau Chen, and decreed:


Dear Editorial Office:
I write to advise you of the findings of the University of Rochester’s investigation into allegations of research misconduct involving 15 articles authored by Drs. Soo Ok Lee and Dr. Yuhchyau Chen. I appreciate your patience while the University completed its thorough investigation in the context of the ongoing global pandemic.
In brief summary, the Investigation concluded that there was no misconduct. There were no allegations of misconduct that implicated Dr. Chen at all based on her role in the research conducted in the lab, and while errors were found and acknowledged, there was no evidence to show that Dr. Lee acted with the requisite intent to falsify the research results. In particular, an allegation that Dr. Lee falsified a research experiment because she did not have access to a particular plasmid, was determined conclusively to be a false allegation.
However, the Investigation did note many errors in the published figures that were identified by the initial allegations set forth on pubpeer.com, additional allegations that came to light during the course of the Investigation, and that were acknowledged by Dr. Lee. Her explanation for the multiple errors can be summarized briefly as a the result of a faulty data management system and
due to multiple experiments conducted in the same time frame, all resulting in the wrong images being published in figures in 13 separate articles published from September 2015-September 2019.

Please note that the Investigation involved the following articles published in your Journal:

[Duan et al 2015, Lee et al 2016, Yang et al 2016, Shen et al 2016, illustrated by LS]

The review of these four articles indicated that there were several errors acknowledged by Dr. Lee and requests have been made for a corrigendum to correct those errors. We agree with these requests as there was no finding of intent to falsify the research results.
To reiterate, there was no finding of misconduct associated with any of the 15 articles subject to the Investigation, but there were errors noted in 13 articles.
We hope that this letter and explanation will prove helpful to your Journal in making its decision[s] regarding the article[s] noted above. Please contact me with any further questions you may have regarding the Investigation and the findings associated with the article[s] published in your Journal.
Sincerely,
Mark B. Taubman, MD
Dean, School of Medicine and Dentistry
Senior Vice President for Health Sciences


Here is the original document:

The letter never mentions Chawshang Chang, probably he was completely exempt from UR Medicine investigation on the accounts of being too busy, or maybe he just punched the research integrity officer on the nose.

Note the sentence “In particular, an allegation that Dr. Lee falsified a research experiment because she did not have access to a particular plasmid, was determined conclusively to be a false allegation” means there was an inside whistleblower in Lee’s lab, who is probably being dealt right now with by Taubman, Chainsaw Chang and their UR medicine colleagues. It won’t be a pretty sight, my heart goes to the whistleblower’s next of kin.

  2. Well written and very depressing. Thanks, I think. The message to everybody around the world: America is a great place to make a lot of money become famous, works especially well if you are willing to cheat.

    You can use that money to purchase a dated but venerable Technics Hi-Fi, which looks quite Yuppies-I-love-Reagan-80’s-hip on a hard wood floor.

    Another Chawnshang Chang Sex Hormone Research Center! – this one’s at the Department of Urology, The First Affiliated Hospital, Xi’an Jiaotong University. Is there a whole chain of them? Is it a franchise?

  4. NMH, the failed scientist and incel

    A complete exoneration by the school suggests that the chainsaw and his Korean sidekick will be back in action. I think the letter also should have said that they are not failed scientists, but maybe because they bring in so much grant money this is a little to obvious for the school to day.
