ENPP1 and arterial calcification, generalized, of infancy, 1: Magnesium has been shown to effectively prevent mineralization in multiple experimental models of vascular calcification, including cultured VSMCs (Kircelli et al, 2012; Louvet et al, 2013; Bai et al, 2015; Ter Braake et al, 2018), uremic rats (Diaz‐Tocados et al, 2017), and mouse models of pseudoxanthoma elasticum (PXE; Abcc6‐null mice) (Gorgels et al, 2010) and generalized arterial calcification of infancy (GACI; Enpp1‐null mice) (Kingman et al, 2017).
