Abstract:The reversed pH gradient across the cell membrane on account of intracellular alkalinization and extracellular acidosis is an importart characteristic of tumor microenvironment. Sodium hydrogen exchanger isoform 1 (NHE1) is ubiquitously expressed at the plasma membrane of many types of cells, which plays a critical role in intracellular pH and cell volume homeostasis. NHE1 plays an important role in the regulation of tumor microenvironment and involves in tumor migration and invasion, which may be a potential new target in anticancer therapy.
