In the original version of the article cited above, there are two confirmed instances of duplication.
In Fig. 3A, the bottom left (siPrkaα1-exo) and top right (siCtr/PA-exo) panels were duplicates.
In Supplementary Fig. 8A, the bottom left corner of the “Metformin −/AMPKα1fl/fl” panel and the “Metformin +/AMPKα1−/−” panel were identical.
The corresponding author of the article contacted the journal to report these duplications and to request an erratum. The erratum request and the original source files to support the publication of this erratum were reviewed and approved by the American Diabetes Association’s Panel on Ethical Scientific Programs.
The corrected images are shown below and are presented in an updated version of the article online (https://doi.org/10.2337/db20-0146).
