Retraction of: npj Precision Oncology https://doi.org/10.1038/s41698-017-0008-z, published online 03 April 2017

This Article1 has been retracted by the Authors because concerns have been raised regarding the identity of the cell lines used for the experimental work. Specifically, re-analysis showed that the S1GODL xenografts matched STR profiles of Ovcar-3 cells, and review of raw flow cytometry data was found to be discordant with presented data. In light of these findings, the identity of the cells within the experimental groups in the manuscript is uncertain, and the conclusions of the work are not reliable.

Authors Vincent La, Rachel Fujikawa, Deanna Janzen, Miguel Nunez, Lin Hwang, Kym Faull, Greg Lawson, and Sanaz Memarzadeh agree with this attraction. Liat Bainvoll did not respond to correspondence from the Publisher about this retraction.
