Correction: Corrigendum: Metabolomic profiles delineate potential role for sarcosine in prostate cancer progression

Nature 457, 910–914 (2009); doi:10.1038/nature07762 In Fig. 4b of this Article, a typographical error was made in reporting sarcosine levels in the DU145 cell line represented. The y axis values should be in the scale of 0–50 pmoles per 106 cells, rather than 0–500 pmoles per 106 cells. This error has been verified and does not affect the conclusion of the paper.
