Correction: Corrigendum: Fatty acid carbon is essential for dNTP synthesis in endothelial cells

Nature 520, 192–197 (2015); doi:10.1038/nature14362 We thank our colleagues from the metabolism community (Emile Van Schaftingen and Guido Bommer, University of Louvain, Belgium, and Frans Schuit, University of Leuven, Belgium), who alerted us to a possible confusion arising from our Article. In particular, the statement in the abstract that “Isotope labelling studies in control endothelial cells showed that fatty acid carbons substantially replenished the Krebs cycle” and similar phrases later in the text could be misunderstood as implying anaplerosis.
