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: “The Expression of Smads in Human Endometrium and Regulation andIinduction inEendometrial Epithelial and Stromal Cells by Transforming Growth Factor-Beta” by Luo, X, Xu, J and Chegini, N. (J Clin Endocrinol Metab 88: 4967–4976, 2003). Because the results cannot be considered reliable, The Journal is retracting the paper.
