Inactivation of the insulin receptor tyrosine kinase and transforming growth factor [beta] pathways are well-known biological effects of fetuin-A, and severe ectopic calcification was found in fetuin-A-deficient mice [9, 10].
Osteopontin (SPP1, OPN) is a multifunctional protein involved in a number of biological processes; chemotaxis, bone remodeling, cell adhesion, inhibition of ectopic calcification, fetal growth and development, cancer metastasis and immune modulatory functions (Schack et al., 2009).
Broadly speaking, two major pathophysiological pathways explain the origins of ectopic calcification, namely the unregulated induction of osteogenesis and second, the loss of mineralization inhibition factors.
Mechanisms of ectopic calcification: implications for diabetic vasculopathy.
FGF23 mutation is associated with ectopic calcification [53].
It is the most common form of ectopic calcification and develops around local tissue damage without any alteration to calcium or phosphate metabolism, for example, in AV.
It selectively binds to hydroxyapatite and directly inhibits the initiation and progression of ectopic calcification. Preclinical models demonstrate that SNF472 reduces the progression of calcium deposition in blood vessels and cardiac tissue.
Instead of many hypothesis and studies, the exact etiology of styloid process and role of ectopic calcification are unknown.
