Another Retraction

Another paper from the Massachusetts Institute of Technology and the Whitehead Institute for Biomedical Research's Robert Weinberg has been retracted, according to Retraction Watch.

This Cell paper, which purported to show that microRNA-31 regulates a number of mRNAs involved in breast cancer metastasis, was retracted due to concerns about how certain figures were constructed, the retraction notice says.

"The scope of the figure preparation issues includes compiling data from independent experiments to present them as one internally controlled experiment, statistical analyses based on technical replicates that are not reflective of the biological replicates, and comparisons of selectively chosen data points from multiple experiments," it adds. "As many of the published figures are therefore not appropriate or accurate representations of the original data, we believe that the responsible course of action is to retract the paper."

This is the fourth paper from Weinberg's group to be retracted in addition to a correction, Retraction Watch notes.
