Abstract

In this issue of Cell, Wu et al. employed C. elegans and human cell experiments to identify a pathway through which metformin increases lifespan and inhibits growth. A key transcriptional target, ACAD10, is activated when metformin induces nuclear exclusion of the GTPase RagC, thereby inhibiting mTORC1 through an unexpected mechanism.
