A week after announcing that a researcher formerly at the University of Chicago had faked the results of more than 70 experiments, the U.S. Office of Research Integrity announced yesterday that one of his colleagues also falsified data.
According to the ORI, Karen D’Souza
reused and falsely relabeled and/or falsely spliced Western blot images, falsified the related densitometry measurements based on the falsified Western blots, and falsified and/or fabricated data for experiments that were not performed or from unrelated experiments.
The faked or falsified data became part of a funded grant from the National Institutes of Health, two papers in the Journal of Biological Chemistry, two posters (including one from a Gordon Conference), and one presentation. The two papers — one of which was retracted without explanation last year, and the other of which D’Souza has agreed to retract — both included Ricky Malhotra, the prolific experiment faker also sanctioned by the ORI, as a co-author.
D’Souza and Malhotra have both agreed to retract 2010’s “Gαq-mediated Activation of GRK2 by Mechanical Stretch in Cardiac Myocytes,” which has been cited 23 times, according to Thomson Reuters Web of Science. A 2011 paper, “G protein-coupled receptor kinase-2 is a novel regulator of collagen synthesis in adult human cardiac fibroblasts,” was retracted in November 2015.
D’Souza agreed to two years of supervision for any Federally funded research, starting May 6, 2016. According to her LinkedIn profile, she left the University of Chicago in 2011 for the University of Arizona, and most recently worked as a research scientist at a Veterans Administration hospital in Phoenix, Arizona.
