The biophysics of arterial decalcification: How carboxylated MGP inhibits hydroxyapatite crystal formation within vascular smooth muscle matrices.
1. Hydroxyapatite Deposition in Vessel Walls
Ectopic calcification of arterial tunica media and intima transforms flexible vascular tissue into rigid, bone-like structures. Calcium phosphate hydroxyapatite crystals deposit along elastic fibers, destroying arterial compliance.
2. Vitamin K2 and Matrix Gla Protein Activation
Matrix Gla Protein (MGP) is the most potent endogenous inhibitor of arterial calcification. Vitamin K2 acts as a cofactor for γ-glutamyl carboxylase, converting inactive uncarboxylated MGP into active carboxylated MGP (cMGP), which binds and dissolves hydroxyapatite crystals.
