Hypoxia-induced mobilization of NHE6 to the plasma membrane triggers endosome hyperacidification and chemoresistance

Abstract

Sodium/proton exchangers (NHEs) are critical regulators of pH within the cell and the extracellular microenvironment. Here, the authors show that hypoxia induces mobilization of NHE6 from endosomal compartment to the plasma membrane in a PKC-dependent manner inducing hyper acidification of endosomes and drug resistance.
