Abstract
CD38 is the main NADase in mammalian cells. It regulates the homeostasis of nicotinamide adenine dinucleotide (NAD+) and extracellular nucleotides. Its function plays an important role in infection and aging. However, its potential functions in tumor cells have not been fully elucidated. In the present study, we demonstrated that lactate, which is derived from tumor metabolism remodeling, upregulates the expression of CD38 through OXPHOS-driven Hippo-TAZ pathway. The highly expressed CD38 converts NAD + to adenosine through the CD203a/CD73 complex and adenosine binds and activates its receptor A2AR, inducing the expression of Snail and promoting the invasion and metastasis of lung cancer cells. This finding elucidates a new perspective on the interplay between NAD + metabolism and glycolysis in tumor development.
期刊介绍：
The Journal of Cell Communication and Signaling provides a forum for fundamental and translational research. In particular, it publishes papers discussing intercellular and intracellular signaling pathways that are particularly important to understand how cells interact with each other and with the surrounding environment, and how cellular behavior contributes to pathological states. JCCS encourages the submission of research manuscripts, timely reviews and short commentaries discussing recent publications, key developments and controversies.
Research manuscripts can be published under two different sections :
In the Pathology and Translational Research Section (Section Editor Andrew Leask) , manuscripts report original research dealing with celllular aspects of normal and pathological signaling and communication, with a particular interest in translational research.
In the Molecular Signaling Section (Section Editor Satoshi Kubota) manuscripts report original signaling research performed at molecular levels with a particular interest in the functions of intracellular and membrane components involved in cell signaling.
