Following an investigation by the University of Florida providing evidence of the senior (third) author's use of manipulated or falsified data in Figures 1,3 and 4, the Journal wishes to retract the paper published in Molecular Human Reproduction (MHR) 16: 215–227 (2010) ‘MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells’.
The information presented in these three figures is key to the conclusions of the paper. Neither Qun Pan nor Xiao Ping Luo were the subject of any investigation. Although beyond its control, the Journal sincerely apologises to its readers.
