ABSTRACT
The PI3K/AKT/mTOR pathway is considered a key therapeutic target in triple-negative breast cancer (TNBC). In this issue of Developmental Cell, Remy et al. challenge this idea by demonstrating that mTORC1 inhibition activates TFEB, promoting MT1-MMP exocytosis, ECM degradation, and increased cell invasion, especially when combined with chemotherapy.
