EXPRESSION OF CONCERN: L. Giordana, B. S. Mantilla, M. Santana, A. M. Silber, and C. Nowicki, “ Cystathionine γ-lyase, an Enzyme Related to the Reverse Transsulfuration Pathway, is Functional in Leishmania spp.,” Journal of Eukaryotic Microbiology 61, no. 2 (2014): 204–213, https://doi.org/10.1111/jeu.12100.

This Expression of Concern is for the above article, published online on 11 January 2014 in Wiley Online Library (wileyonlinelibrary.com), and has been issued by agreement between the journal Editor-in-Chief, Joel B. Dacks; The International Society of Protistologists; and Wiley Periodicals LLC. The Expression of Concern has been agreed due to concerns raised by third parties. A duplication of the Western Blot bands depicting “CS_P” and “CGL_P” has been identified in Figure 5B. The authors have acknowledged an unintentional duplication of one of the western blot images corresponding to CS_P or CGL_P during figure preparation, rather than duplication of the individual band. The authors declare that none of the western blots in the figure were altered in any form. However, due to the time elapsed since publication, the original data could not be recovered to rectify the mistake. As the conclusions are not affected by the issue detected, the journal has decided to issue an Expression of Concern to inform and alert the readers.
