Rakesh Kumar, a researcher with six recent corrections and one retraction, has had one of those corrections upgraded to a retraction.
Here’s the unhelpful notice, from Molecular Endocrinology:
The August 2007 Molecular Endocrinology article by by Gururaj et al, “Estrogen Induces Expression of BCAS3, A Novel Estrogen Receptor-alpha Coactivator, through Proline-, Glutamic Acid-, and Leucine-Rich Protein-1 (PELP1)” (Mol Endocrinol 21:1847–1860, doi: 10.1210/me.2006-0514), is withdrawn by the authors.
This was the correction:
In the August 2007 Molecular Endocrinology article by Gururaj et al. “Estrogen induces expression of BCAS3, a novel estrogen receptor-alpha coactivator, through proline-, glutamic acid-, and leucine-rich protein-1 (PELP1)” (Mol Endocrinol 21:1847–60; Epub 2007 May 15. PubMed PMID: 17505058; doi: 10.1210/me.2006–0514), the authors note certain inadvertent errors in the Actin mRNA lanes in Figure 3H and splicing in the pS2 ChIP in Figure 7A upper panel while composing the panels.
The authors are replacing the published Figures 3H and 7A panels with an erratum using data from repeat experiments. There is no change in the text and figure legends. These changes do not change the original scientific conclusions and the validity of the findings remains the same. The authors regret the error.
The original paper has been cited nine times, according to Thomson Scientific’s Web of Knowledge.
Kumar, who was at MD Anderson when the paper was originally published. appears to have left the George Washington University, where he was recently chair of biochemistry. He is a visiting distinguished professor of biotechnology at the Rajiv Gandhi Center for Biotechnology in Kerala, lndia. Our requests for comment from him have gone unanswered.
