Biologist loses second paper — again, for unvalidated figures

Cellular SignallingA researcher at Case Western Reserve University in Ohio has retracted a second paper after a review found the figures didn’t match the original data.  

Last year, we reported on a previous retraction of a paper co-authored by biologist Alan Levine in Inflammatory Bowel Diseases, which was pulled for the exact same reason; even the retraction notices use similar language. The first author on both papers is Debasmita Mandal, also listed at Case Western Reserve University.

Here’s the retraction notice for “REDOX regulation of IL-13 signaling in intestinal epithelial cells: usage of alternate pathways mediates distinct gene expression patterns,” published by Cellular Signalling: Continue reading Biologist loses second paper — again, for unvalidated figures

Singapore investigation leads to two retractions, two more on the way

cov150hAuthors have retracted papers from Cell Metabolism and the Journal of Biological Chemistry after an investigation in Singapore found issues, including falsified data. The investigation is ongoing, and two additional retractions, along with two corrections, are on the horizon.

The investigation looked into papers by first authors Sudarsanareddy Lokireddy, now a postdoc at Harvard, and Sandhya Sriram, a postdoc at the Agency for Science, Technology and Research in Singapore. Led by the Nanyang Technological University in Singapore, where some of the work was done, the investigation concluded that there were issues with six papers on which either Sriram or Lokireddy was first author.

All authors but Lokireddy have agreed to retractions or corrections. Ravi Kambadur of NTU, and Mridula Sharma at the National University of Singapore, are the last two authors on all the papers.

According to a notice from the NTU, the “investigation found a number of instances of alterations to data” in three papers on which Lokireddy is first author. One of those was retracted December 1 by Cell Metabolism: Continue reading Singapore investigation leads to two retractions, two more on the way
