Researchers have retracted their third paper due to missing original data, following an investigation at their former institution in New York.
We’ve previously reported on two retractions of papers co-authored by Bhagavathi Narayanan and Narayanan K. Narayanan, previously based at the New York University (NYU) School of Medicine. The studies were pulled when the pair couldn’t provide original images to investigators at NYU School of Medicine. One author has blamed the lack of original data on the abrupt closure of her previous institution in 2004, after it allegedly misspent millions in federal grants.
However, the latest retraction affects a paper published eight years later in the International Journal of Oncology. Its coauthors include Bhagavathi Narayanan, Narayanan K. Narayanan and Rajkishen Narayanan; we haven’t been able to uncover if there is a relation between them.
A spokesperson for the NYU School of Medicine sent us this statement: Read the rest of this entry »
A 2006 paper investigating the effects of docosahexaenoic acid (DHA) and celecoxib on prostate cancer cells has been retracted because it appears to contain panels that were duplicated, and the authors could not provide the raw data to show otherwise.
This is the second paper the authors have lost because they couldn’t furnish the original data to defend their work against allegations of image manipulation. The reason: the Institute for Cancer Prevention in New York, where the authors did the work, shut its doors abruptly in 2004, co-author Bhagavathi A. Narayanan told us. (The institute closed thanks to $5.7 million in grant that was misspent, the New York Post reported at the time.)
Recently, some of Narayanan’s papers have been questioned on PubPeer; her work has been the subject of an investigation at New York University, where Narayanan is now based.
Narayanan told us that the criticism of their work has deeply affected her and her co-authors:
An article about how a COX-2 inhibitor (celecoxib) inhibits growth of prostate cancer in rats is being retracted after the authors were unable to provide an investigation committee at New York University with the backup they were asking for.
When the paper was published in 2003, first author Bhagavathi Narayanan worked at the Institute for Cancer Prevention in New York (also known as the American Health Foundation). But when the institute went broke the next year — thanks partly to lavish salaries and offices, as the New York Post reported — the authors claim they could no longer obtain back up for an image in the paper, once it was questioned years later by NYU, where Narayanan is now based.
Here’s the retraction note, published in Clinical Cancer Research:
