Our paper reported that overexpression of tRNAiMet can promote cell proliferation and transformation. It has now become clear that images in several figures are duplications that do not represent the experiments described in the legends. Although we remain convinced that tRNAiMet can have proliferative and oncogenic effects based on subsequent work in our lab and others, given these issues with the validity of the figures, we believe the most appropriate course of action is to retract the paper. We deeply regret this circumstance and apologize to the community. The first author, L.M., has not agreed to this Retraction.
We wanted to know whether there had been an investigation, and why Marshall had declined to sign the notice. Professor Karen Vousden, director of the Beatson Institute, tells Retraction Watch:
We launched an investigation into this matter and we’re unable to comment further until the investigation is complete. All authors were invited to sign the retraction notice.
Senior author Robert White told us he is out on sick leave.
We’ve tried to reach Marshall,
now until July a post-doctoral fellow at the University of Alberta in Calgary, for comment, and will update with anything we learn.
The Cell paper has been cited 84 times, according to Thomson Scientific’s Web of Knowledge.
