Abstract

Macropinocytosis coordinates non-specific uptake of macromolecules and fluid. Cancers employ macropinocytosis to obtain nutrients to support their metabolic homeostasis. In this issue of Developmental Cell, Lee et al. (2019) report that glutamine deprivation boosts macropinocytosis via EGFR signaling induction, providing a fine-tuned mechanism by which cancers adapt to nutrient supply.
