ENPP1 in the Regulation of Mineralization and Beyond

Trends Biochem Sci. 2019 Jul;44(7):616-628. doi: 10.1016/j.tibs.2019.01.010. Epub 2019 Feb 21.

Abstract

ENPP1 is well known for its role in regulating skeletal and soft tissue mineralization. It primarily exerts its function through the generation of pyrophosphate, a key inhibitor of hydroxyapatite formation. Several previous studies have suggested that ENPP1 also contributes to a range of human diseases including diabetes, cancer, cardiovascular disease, and osteoarthritis. In this review, we summarize the pathological roles of ENPP1 in mineralization and these soft tissue disorders. We also discuss the underlying mechanisms through which ENPP1 exerts its pathological effects. A fuller understanding of the pathways through which ENPP1 acts may help to develop novel therapeutic strategies for these commonly diagnosed morbidities.

Keywords: ENPP1; cardiovascular disease; diabetes; mineralization; pathological effects.
