Acid-base homeostasis is crucial for physiological function and pathology. NBCn1, a transmembrane transporter, plays a significant role in cellular pH regulation and HCO3- transport. However, the expression and activity of NBCn1 remain unclear. Furthermore, NBCn1 is involved in various cellular processes. This review provides an overview of recent research on NBCn1, including its basic features, regulation, tissue-specific physiology, and potential application in cancer therapy.
Acid-base homeostasis is critical for proper physiological function and pathology. The SLC4 family of HCO3- transmembrane cotransporters is one of the HCO3- transmembrane transport carriers responsible for cellular pH regulation and the uptake or secretion of HCO3- in epithelial cells. NBCn1 (SLC4A7), an electroneutral Na+/HCO3- cotransporter, is extensively expressed in several tissues and functions as a cotransporter for net acid extrusion after cellular acidification. However, the expression and activity level of NBCn1 remain elusive. In addition, NBCn1 has been involved in numerous other cellular processes such as cell volume, cell death/survival balance, transepithelial transport, as well as regulation of cell viability. This review aims to give an inclusive overview of the most recent advances in the research of NBCn1, emphasizing the basic features, regulation, and tissue-specific physiology as well as the development and application of potent inhibitors of NBCn1 transporter in cancer therapy. Research and development of targeted therapies should be carried out for NBCn1 and its associated pathways.
