Anil Sood and other questionable stars of MD Anderson

Anil Sood and other questionable stars of MD Anderson

The MD Anderson Cancer Center, part of the University of Texas and located in Houston, is a giant hub of huge cancer research money, even for US standards. They also do a lot of science there, which only purpose seems to be publishing in big journals in order to generate even more money. If there is any genuine interest to help cancer patients with actual research: this stands in a stark contrast with MD Anderson’s evident attitude to research reproducibility and data integrity. A number of their star researchers who published in most respectable journals papers, had their data flagged on the whistleblowing platform PubPeer as highly problematic. Yet MD Anderson apparently cannot care less. Their star cancer researcher and businessman Raghu Kalluri was never investigated for many problems in his publications, either in those with or those without his misconduct-tainted Portuguese co-author and ex-MD Anderson employee Sonia Melo. When nobody ever investigates your research practices (e.g., because your research institution is blinded by the investor money you brought in), you will per definition never be found guilty of any misconduct. This is probably exactly why the elite journal Nature recently accepted a new paper from the Kalluri lab (Kamerkar et al 2017), on the same topic of exosomes as cancer biomarkers as his irreproducible earlier masterpiece with Melo (Melo et al, Nature 2015). The new Nature paper even again features the same disgraced co-author, who lost a Nature Genetics paper (Melo et al, 2009) and her EMBO Young Investigator funding due to data manipulation.

There is more evidence for research misconduct at MD Anderson. Continue reading “Anil Sood and other questionable stars of MD Anderson” →

Fishy peer review at Science, by citizen scientist Ted Held

Fishy peer review at Science, by citizen scientist Ted Held

Sweden and the international research community recently faced yet another research misconduct scandal. It was about a Science paper by Oona Lönnstedt and Peter Eklöv, which in 2016 made worldwide headlines with its findings that young fish larvae (or fry), namely Eurasian perch, would eat up plastic pollution like teenagers eat fast food. It soon turned out the research was apparently never performed as described, the original data was missing (allegedly stored only on a laptop, which was then stolen from a car), the results likely made up. The Lönnstedt & Eklöv 2016 paper received an editorial expression of concern in December 2016 and was eventually retracted on May 26th 2017 following misconduct findings by the Swedish Central Ethics Review Board (CEPN), while the two Swedish whistleblowers Josefin Sundin and Fredrik Jutfelt, initially themselves stiffly criticised by the University of Uppsala, were finally exonerated (see panel verdict here and here, further documents here and here).  I also make available here the original report by the whistleblowers to the University of Uppsala and CEPN, detailing their “Key points highlighting scientific misconduct by Lönnstedt and Eklöv”. For further reference, read Martin Enserink’s reporting for Science here, here and here.

However, there was more to that Science paper than fraudulent science. Even if the results were not made up, their objective scientific value would still be very questionable, because it had very little connection to the reality of the plastic pollution in the oceans and the fish feeding behavior. The uniformly small, freshly industrially synthesized plastic balls which were fed to the fishes were not really representative of the actual plastic particles polluting our seas. But even those arbitrary chosen particles were not likely to have been eaten by the fishes voluntarily. If the fishes ever did swallow those, it was probably because they were simply made to, being at the point of death by starvation, something which rarely ever happens to actual plankton-feeding fishes in the sea. Of course one cannot expect peer reviewers to spot misconduct and data manipulation, but objectively assessing scientific methodology, result and conclusions of a manuscript is actually what the peer review is all about. One does wonder why the “highly qualified, dedicated” reviewers at Science failed to notice all these obvious scientific shortcomings, and instead decided that Lönnstedt & Eklöv work belonged indeed to “the very best in scientific research”. Was it because the socially and ecologically relevant conclusions sounded so important and welcome, that one simply had to blindly ignore the poor science behind them?

Peer review ghost-writing, or do professors understand plagiarism?

Peer review ghost-writing, or do professors understand plagiarism?

Every academic will probably agree that plagiarism is wrong. It is absolutely not OK to pass someone’s else’s intellectual work as one’s own. Plagiarised research papers get retracted regularly, on several occasions plagiarism in dissertation led to withdrawal of doctorate, most notably among several German politicians. There is however one aspect of academic life where plagiarism is so normal that the parties involved  do not even consider it to be plagiarism, neither the plagiarist, nor the victim of plagiarism. It is the academic peer review, the process where research colleagues are invited by journal editors to submit their expert opinion on the scientific quality of the manuscript under editorial consideration. and it is not the incompetent youth plagiarising there, but professors, principal investigators (PIs), research institute directors and clinic heads. Our academic elite plagiarises daily, without anyone even raising an eyebrow.  Continue reading “Peer review ghost-writing, or do professors understand plagiarism?” →

Data manipulation evidence in Helin Vakifahmetoglu papers “warrants no further consideration”

Data manipulation evidence in Helin Vakifahmetoglu papers “warrants no further consideration”

The Swedish Karolinska Institutet (KI) has investigated its own cell biologist and well-funded autophagy researcher Helin Vakifahmetoglu-Norberg, following my publishing of a dossier with evidence for data manipulations in her papers. Also PubPeer evidence was considered. This was a second investigation of Vakifahmetoglu-Norberg, who was fully acquitted by KI already in 2016. While the new KI investigation progressed, one of Vakifahmetoglu-Norberg’s publications was retracted (Shen et al, Oncogene 2008), due to image duplications and unavailability of original data. With their second decision, KI again exonerated  Vakifahmetoglu-Norberg from all suspicions. One of the reasons was: since the Shen et al 2008 is retracted, it ceases to exist. Hence, all image duplications it shares with other Vakifahmetoglu-Norberg papers cease existing also. Other arguments were the author’s assertions to have reproduced more than 10 year old results faithfully (since the original data was unavailable), or her presenting evidence that similar looking images were in fact dissimilar. Unfortunately, where such original data could be recovered, it was shown only to internal investigators at KI, noone else. The case is closed, no appeal is possible. There will be no corrections even, unless journals do the unlikely thing and decide not to accept the KI decision.

Another Vakifahmetoglu paper (Imreh et al, J Cell Biol. 2011) is still under KI investigation but she has officially nothing to do with it. KI announced to follow this through with her former boss and the paper’s last author, Boris Zhivotovsky. He is under another KI investigation already, together with several of his colleagues including the  department’s prefect Ulla Stenius (see my report here), who received the KI letter about  Vakifahmetoglu whitewashing in cc.  Continue reading “Data manipulation evidence in Helin Vakifahmetoglu papers “warrants no further consideration”” →

German Leibniz institute director Karl Lenhard Rudolph guilty of misconduct

German Leibniz institute director Karl Lenhard Rudolph guilty of misconduct

A major misconduct finding hits German life sciences. Karl Lenhard Rudolph, stem cell and ageing researcher, director of the Fritz-Lippmann-Institute (FLI) of the Leibniz Society, was found guilty of research misconduct by an investigation of the Leibniz Society, in a decision published on June 15th. 11 papers in total were investigated, going back as far as 2001. One paper is to be retracted, seven Errata were requested. The investigation confirmed duplications of image parts, inappropriate splicing, rigged loading controls etc. No original data or lab books were available.

Just in Mai 2016, Rudolph’s FLI was raided by the police “on  suspected breaches of the animal welfare and drug law, as well as embezzlement” . All animal experimenting was stopped till present day, according to Radio Jena, other sources quoted Rudolph in May 2017 that mouse experiments were approved again, though the police investigation continued. Rudolph also admitted that his own lab was also part of the problem and that 13,000 mice were killed unnecessarily. Was Leibniz Society’s recent tough and public disciplinary action upon FLI director Rudolph the consequence?

The translated report on Rudolph’s research misconduct (my own version) is published below, the German original is here. I have not yet determined which publications from Rudolph lab were investigated, but 5 Rudolph papers were previously flagged on PubPeer. His institute, located in the Eastern German town of Jena, is now banned from Leibniz funding for 3 years, FLI now must report back to the Leibniz Executive Board until November 1st 2017 on the improvements regarding data documentation, quality control as well as tutoring and supervision of employees.

Expert review: Macchiarini papers on plastic trachea transplants are misconduct

Expert review: Macchiarini papers on plastic trachea transplants are misconduct

Bad times for the scandal surgeon Paolo Macchiarini and his acolyte Philipp Jungebluth. Misconduct findings led previously to retraction of an oesophagus transplant paper, with more soon to be expected, their employments in academia seem to be definitely a thing of a past. Macchiarini’s big plans of world-shattering trachea and oesophagus transplants in Russia went bust, when his grant funding was not extended and the Federal University of Kazan waved him goodbye. The master’s acolyte Jungebluth is currently suing me in court about my reporting on his own past employment, because he managed to convince the Berlin judge when passing the injunction that all his now proven research misconduct and patient abuse, which led to deaths of several patients, plus several other dishonest deeds of his, had in fact perfectly qualified him for an academic research career at the University of Heidelberg in Germany. A career he claims to have aborted entirely on his own accord, hence his (now only 1/3 successful) court injunction against me. Jungebluth, after having said farewell to his 8 years of thorax surgery training in vain, even claimed in court to be desperately wanted as thoracic surgeon by all Berlin hospitals, including the huge university hospital Charité.

Which brings us to the recent setback for the two trachea transplanters. Their publications regarding the plastic trachea operations at the Karolinska Institutet (KI) in Stockholm, which left three patients dead, were investigated by two external experts. One of the experts was Martin Björck, professor of surgery at University of Uppsala, the other was Detlev Ganten, professor emeritus of pharmacology and former CEO of the Charité. And their fresh report, submitted to the Swedish Central Ethics Review Board (CEPN), does not read like the Berlin Charité or any other medical research institution in Germany, or anywhere else for that matter, might ever consider employing Jungebluth. The central Lancet publication, describing the first plastic trachea transplant performed on Andemariam Beyene (Jungebluth et al, 2011), was slammed as based on misconduct, both ethical as well as research misconduct. It is the same Lancet paper Jungebluth presented to Berlin court as evidence of his scientific fame and excellence.

Melo and Kalluri defend discredited Nature paper with preprint, where they admit data “adjustments”

Melo and Kalluri defend discredited Nature paper with preprint, where they admit data “adjustments”

Sonia Melo, the Portuguese cheater scientist and her former US-boss Raghu Kalluri issued some days ago a biorxive preprint, which sole purpose is to defend their discredited Nature paper from 2015. There, they originally claimed to have found a unique biomarker for early pancreatic cancer, a much hailed promise to save lives of many cancer patients. However, soon it was found out that the results were not reproducible, the Nature paper Melo et al, 2015 contained evidence of data manipulation (just like other Melo publications with Kalluri and her PhD boss Manel Esteller). The antibody, on which the central evidence for the allegedly unique pancreatic cancer biomarker glypican 1 (GPC1) was based, proved to be delivering staining artefacts; the vendor Thermo Scientific soon discontinued it. Even Kalluri seemingly distanced himself from his results.

Now in their new preprint, Melo and Kalluri claimed to have perfectly reproduced their original 2015 GPC1 results with a new antibody, which however proved to be likely exactly the same as the old one, but sold by a different vendor.  As soon as this became known, the authors issued a new preprint version just two days later, featuring yet another entirely new GPC1 antibody, with an utterly new set of results to complement the 6 day older ones.  However, also these results are most likely useless. The authors namely freely admit in their preprint method description to have intentionally manipulated their flow cytometry (FACS) data to obtain a positive signal specifically where needed. It seems that one full professor and three research group leaders have absolutely no understanding about data integrity in flow cytometry (or maybe even in research in general). Obviously, they simply adjust the FACS settings for each sample in an analytic row any way it pleases them until they see a result they like. As they don’t even hide it, they seem to think this is the proper way to do science.
