The Journal of Clinical Endocrinology & Metabolism has received a report describing an investigation by The University of Florida which found substantial data misrepresentation in the following article: “Differential Expression, Regulation, and Induction of Smads,Ttransforming Growth Factor-Beta Signal Transduction Pathway in Leiomyoma, and Myometrial smooth muscle cells and Alteration by Gonadotropin-Releasing Hormone Analog” by Xu, J, Luo, X and Chegini, N. (J Clin Endocrinol Metab) 88: 1350–1361, 2003). Because the results cannot be considered reliable, The Journal is retracting the paper.
