Stopping the fat: Repurposing an antidepressant for cancer treatment

Abstract

In this issue of JEM, Chu and An et al. (2022. J. Exp. Med. https://doi.org/10.1084/jem.20221316) describe the role of the tricyclic antidepressant nortriptyline in inhibition of fatty acid uptake. Nortriptyline promotes cell acidification and suppresses macropinocytosis, providing a link between fatty acid uptake and tumor progression.
