When we learned earlier this week that Bharat Aggarwal, the MD Anderson researcher under investigation there for possible misconduct, had directed his attorneys to send us a pull-all-your-posts-about-our-client-or-we’ll-sue-you letter, we wondered if he’d included the Houston institution in that decision.
Turns out he’d been acting on his own. Read the rest of this entry »
Today, we received a letter from the Houston firm of Paranjpe & Mahadass LLP telling us to pull every post related to their client off our site within 20 days, or they’d “file a lawsuit against” us on his behalf.
We’ve written about mega-corrections that allow scientists to retrace virtually all of their steps yet preserve their publications as supposedly legitimate. And we’ve seen plenty of corrections that allow authors to assert that their conclusions are correct when evidently important pieces of data are themselves unreliable.
Now comes a correction that seems to us to strike the right chords, given the fact that editors are to a large extent at the mercy of authors in these situations. Read the rest of this entry »
Bharat Aggarwal, an influential MD Anderson researcher who has been accused in the blogosphere of manipulating images in a slew of published studies, acknowledged to Retraction Watch that the Houston institution is investigating the matter. Reached by Retraction Watch by phone at his office, Aggarwal said MD Anderson
has been looking into it and I think that they will tell everybody what it is all about. I think that somebody out there is putting this whole thing together and their mind is made up.
However, Aggarwal, chief of the center’s cytokine research section, denied that any retractions of his papers were forthcoming. He refused to comment on whether officials had confiscated his computer, as a commenter to this blog has claimed. Read the rest of this entry »
Bharat Aggarwal is the last author on all three papers. He is now up to six corrections, two unexplained withdrawals, and two Expressions of Concern. He’s also threatened to sue us in the past, and has told us that his institution has been looking into his work.
Only one note specifies that the correction does not affect the paper’s conclusions.
First up: “Inhibition of growth and survival of human head and neck squamous cell carcinoma cells by curcumin via modulation of nuclear factor-κB signaling,” published in the International Journal of Cancer and cited 168 times, according to Thomson Scientific’s Web of Knowledge. The issues span two figures, according to the erratum note:
Two Expressions of Concern in Blood for MD Anderson’s Aggarwal, who has threatened to sue Retraction Watch
Bharat Aggarwal, the MD Anderson researcher who has threatened to sue us while under investigation by his institution for alleged misconduct, now has two Expressions of Concern in addition to two corrections and two unexplained withdrawals.
Both of the papers were published in Blood. The Expression of Concern for “Gambogic acid, a novel ligand for transferrin receptor, potentiates TNF-induced apoptosis through modulation of the nuclear factor-κB signaling pathway,” reads: Read the rest of this entry »
Bharat Aggarwal, the highly cited MD Anderson Cancer Center researcher who has confirmed to us that his work is under investigation by the institution, has a correction of his work in the Journal of Molecular Medicine. Troubled images are to blame — as they have been in previous retractions, and at least one other correction, of Aggarwal’s papers.
The paper, “Celastrol suppresses invasion of colon and pancreatic cancer cells through the downregulation of expression of CXCR4 chemokine receptor,” was published in December 2010 and cited 15 times since, according to Thomson Scientific’s Web of Knowledge.
Bharat B. Aggarwal, the MD Anderson researcher under investigation at his institution over concerns of image manipulation, has withdrawn a second paper, although you’d never know why from the statement.
The notice for the article, “Evidence for the critical roles of NF-κB p65 and specificity proteins in the apoptosis-inducing activity of proteasome inhibitors in leukemia cells,” is pretty minimal: Read the rest of this entry »
Whether it’s a one-off or a sign of things to come, Bharat Aggarwal, the MD Anderson scientist at the center of a blogospheric storm—and an institutional investigation—over the validity of his data, has had a paper withdrawn by the journal Cancer Letters. Read the rest of this entry »
That was the emotional sequence for some significant number of researchers around the world on Friday. In the space of several hours, they received word that they were among the scientific 1% — the most cited researchers on the planet — then learned that…well, they actually weren’t.
Here’s the letter — subject line, “Congratulations Highly Cited Researcher!” — and the retraction…erm, apology (click to enlarge): Read the rest of this entry »
