Background: Sodium-calcium exchanger (NCX1) regulates calcium in renal epithelial cells. Results: Na,K-ATPase -subunit regulates NCX1 membrane localization and reduced NCX1 expression or its functional inhibition increases cell migration. Conclusion: NCX1 plays a pivotal role in activation of calcium dependent migration via calmodulin/PI3K/ERK. Significance: Identifying regulators of epithelial cell motility is important in establishing novel therapeutic targets in fibrosis and cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
