BIOCHEMISTRY PNAS is publishing an Editorial Expression of Concern regarding the following article: “A bifunctional tRNA import receptor from Leishmania mitochondria,” by Srikanta Goswami, Gunjan Dhar, Saikat Mukherjee, Bidesh Mahata, Saibal Chatterjee, Pratik Home, and Samit Adhya, which appeared in issue 22, May 30, 2006, of Proc Natl Acad Sci USA (103:8354–8359; published ahead of print May 19, 2006, doi:10.1073/pnas.0510869103).
The editors wish to note that a reader has raised questions about the apparent duplication of certain figures in this article. We have reviewed the matter and are concerned about the validity of the results. The matter has been forwarded to the Indian Institute of Chemical Biology (IICB) to investigate further. We are awaiting the findings of IICB to determine the appropriate next steps.
