Bharat B. Aggarwal is an Indian-American biochemist. His research has been in the areas of cytokines, the role of inflammation in cancer, and the anti-cancer effects of spices and herbs, particularly those of curcumin (a chemical constituent of the spice turmeric). He was a professor in the Department of Clinical Immunology, Bioimmunotherapy, and Experimental Therapeutics at University of Texas MD Anderson Cancer Center in Houston, Texas.[1]

In 2012, MD Anderson launched a review of Aggarwal's research after the federal government notified them of allegations of fraud by academic whistleblowers in as many as 65 of Aggarwal's published papers; the concerns were about data images that had been reused and manipulated to represent different results.[2][3][4] He retired at the end of 2015; his departure was not made public until February 2016.[1][5]

As of September 2018, 28 papers published by Aggarwal have been retracted.[6]

Career

Aggarwal holds a Bachelor of Science degree from the University of Delhi (1970), a Master of Science degree from Banares Hindu University (1972) and a Doctor of Philosophy degree from the University of California, Berkeley (1977), all in biochemistry. He completed a postdoctoral fellowship at the University of California, San Francisco and was employed as a scientist at Genentech from 1980 to 1989, where his team characterized the cytokines TNF-alpha and TNF-beta. Aggarwal then served as Chief of the Cytokine Research Section, Department of Clinical Immunology, Bioimmunotherapy, Experimental Therapeutics at MD Anderson Cancer Center of the University of Texas in Houston from 1989 to 2015.[7][8] He has published over 500 articles and is an ISI Highly Cited Researcher.[9] As of 2016, he had an h-index of 160 and 94,234 citations to 433 articles.[10]

Aggarwal's research has focused on potential anti-cancer properties of herbs and spices, particularly curcumin, found in the spice turmeric.[7][11] Aggarwal co-founded a company in 2004 called Curry Pharmaceuticals, based in Research Triangle Park, N.C., which was seeking to develop drugs based on synthetic analogs of curcumin.[7][12] SignPath Pharma, a company seeking to develop liposomal formulations of curcumin, licensed three patents invented by Aggarwal related to that approach from MD Anderson in 2013.[13]

Scientific misconduct

In 2012, MD Anderson initiated a review of Aggarwal's research after the U.S. Department of Health and Human Services' Office of Research Integrity notified the institution that academic whistleblowers had found evidence of image manipulation in 65 published papers by Aggarwal.[2][14]

Aggarwal's lawyer proposed legal action against the blog Retraction Watch in 2013 after they wrote about several of his article corrections and retractions.[15] In February 2016, the journal Biochemical Pharmacology retracted seven research articles with Aggarwal as a co-author, him being senior or first author on six of these.[4] The retraction notices stated this was "because the data integrity has become questionable".[3]

In January 2016, an article in The Times of India listed Aggarwal as the founder director of the Anti-inflammation Research Institute in San Diego, California.[16] Retraction Watch noted that the institute does not have a functioning website.[17]

In February 2016 MD Anderson Cancer Center confirmed to Retraction Watch that Aggarwal retired from the institute on December 31, 2015.[5][1]

In June 2016, following an investigation by MD Anderson Cancer Center, the journal Molecular Pharmacology retracted two papers coauthored by Aggarwal, citing “inappropriate” or “unacceptable” image manipulation.[18] By April 2018 19 of Aggarwal's articles, published in 7 research journals, were ultimately retracted by the publishers.[19][3][20][1] In September 2018, an additional nine articles by Aggarwal were retracted in journals published by the American Association for Cancer Research.[21]
