In this review, we focus on the secreted form of nicotinamide
phosphoribosyltransferase (NAMPT); extracellular NAMPT (eNAMPT), also known as
pre-B cell colony-enhancing factor or visfatin. Although intracellular NAMPT is a
key enzyme in controlling NAD metabolism, eNAMPT has been reported to function as
a cytokine, with many roles in physiology and pathology. Circulating eNAMPT has
been associated with several metabolic and inflammatory disorders, including
cancer. Because cytokines produced in the tumour micro-environment play an
important role in cancer pathogenesis, in part by reprogramming cellular
metabolism, future improvements in cancer immunotherapy will require a better
understanding of the crosstalk between cytokine action and tumour biology. In
this review, the knowledge of eNAMPT in cancer will be discussed, focusing on its
immunometabolic function as a metabokine, its secretion, its mechanism of action
and possible roles in the cancer micro-environment.
