Author Correction: Metformin inhibits gluconeogenesis via a redox-dependent mechanism in vivo

In the version of this article originally published, the VPC and VCS flux data shown in Fig. 6e,f were inadvertently duplicated from Fig. 5j,k. The correct data are now shown in Fig. 6e,f. In these corrected data, VPC flux in response to chronic oral metformin treatment was still significantly decreased (Fig. 6e), and there was still no impact of metformin on VCS flux (Fig. 6f). Therefore, the text describing these data remains the same and this correction does not change the conclusion of this study.
