TMEM87A suppresses ferroptosis and increases cancer immunotherapy resistance by maintaining the Golgi apparatus pH homeostasis
Abstract Most membrane-bound organelles have been linked to the initiation and execution of ferroptosis. However, the role of the Golgi apparatus and its resident proteins in ferroptosis remain elusive. Here we show that ferroptosis inducer triggers rapid oxidation of Golgi membrane lipids in the early phase of ferroptosis, resulting in disruption of Golgi pH. The Golgi-localized transmembrane protein TMEM87A is identified to mediate ferroptosis resistance through buffering Golgi pH.
ELMO2 is a therapeutic vulnerability in mesenchymal-like and drug-resistant non-small cell lung cancer
Abstract Epithelial-mesenchymal transition drives tumor metastasis and therapeutic resistance, yet few treatments have been developed that target this process. Here, we show that ELMO2 represents a specific vulnerability in mesenchymal-like cells. ELMO2 suppression induces excessive autophagy and cell death via FAK activity inhibition. We identify ELMO3 as a functional paralog that compensates for ELMO2 loss, establishing a synthetic lethal interaction.
