24. Npp1 promotes atherosclerosis, potentially mediated by Opn expression in ApoE knockout mice PMID: 21477221
25. ENPP1 plays multiple and distinct roles in the development of mineralized tissues and that the influence of ENPP1 on osteoblast differentiation and gene expression may include a mechanism that is independent of its catalytic activity. PMID: 21930712
26. RAGE promotes ectopic chondrogenic differentiation and arterial calcification in Enpp1-/- mice. PMID: 21099228
27. NPP1 does not have a major role in PP(i) generation from ATP at the level of MVs, in contrast to its accepted role on the surface of the osteoblasts and chondrocytes, but rather acts as a phosphatase in the absence of TNAP. PMID: 19874193
28. Data show that reconstitution of TNAP and NPP1 into proteoliposome membranes generates a phospholipid microenvironment that allows the kinetic study of phosphosubstrate catabolism in a manner that recapitulates the native MV microenvironment. PMID: 20048161
