The Proton-Coupled Monocarboxylate Transporter Hermes Is Necessary for Autophagy during Cell Death.

ABSTRACT: Nutrient availability influences the production and degradation of materials that are required for cell growth and survival. Autophagy is a nutrient-regulated process that is used to degrade cytoplasmic materials and has been associated with human diseases. Solute transporters influence nutrient availability and sensing, yet we know little about how transporters influence autophagy. Here, we screen for solute transporters that are required for autophagy-dependent cell death and identify CG11665/hermes. We show that hermes is required for both autophagy during steroid-triggered salivary gland cell death and TNF-induced non-apoptotic eye cell death. hermes encodes a proton-coupled monocarboxylate transporter that preferentially transports pyruvate over lactate. mTOR signaling is elevated in
