Significance
NHE7 regulates cytosolic pH through Golgi acidification, which points to the Golgi as a "proton sink" for metabolic acid. Disruption of cytosolic pH homeostasis via NHE7 suppression compromises PDAC cell viability and tumor growth.See related commentary by Ward and DeNicola, p. 768.This article is highlighted in the In This Issue feature, p. 747.
