MGP acts as a strong inhibitor of soft tissue calcification. As an illustration, MGP knockout mice develop massive vascular calcification in their first weeks of life and die within 2 months of vessels' rupture (Luo et al., 1997). To acquire its full calcification inhibitory activity, MGP needs to

Novel conformation-specific antibodies against matrix gamma-carboxyglutamic acid (Gla) protein: undercarboxylated matrix Gla protein as marker for vascular calcification.

OBJECTIVE Matrix gamma-carboxyglutamic acid (Gla) protein (MGP), a vitamin K-dependent protein, is a potent in vivo inhibitor of arterial calcification. We hypothesized that low endogenous production of MGP and impaired carboxylation of MGP may contribute to the development or the progression of vascular disease. METHODS AND RESULTS Novel conformation-specific antibodies against MGP were used...

مطالعه غلظت سرمی و پلی مورفیسم rs1800799 پروموتور ژن MGP در بیماران با تنگی عروق کرونر

Background and purpose: Coronary artery stenosis is a progressive process associated with artery calcification. Although the role of matrix Gla protein (MGP) is not completely clear but its expression in vascular smooth muscle cells (VSMCs) and sub-endothelial macrophages suggests a role in vascular calcification. The rs1800799 is one of the polymorphisms oriented within transcription factor el...

Conflicting forces of warfarin and matrix gla protein in the artery wall.

1 reported that 2 weeks of warfarin treatment in young rats caused massive focal calcification of the artery media. It had been known for years that warfarin could induce mineral deposition in the arteries of rodents, 2 and the phenomenon was so robust that warfarin was often used as an experimental model for vascular calcification, but the mechanism was unknown. In this issue, Tantisattamo et ...

Inactivation of the Osteopontin Gene Enhances Vascular Calcification of Matrix Gla Protein–deficient Mice

Osteopontin (OPN) is abundantly expressed in human calcified arteries. To examine the role of OPN in vascular calcification, OPN mutant mice were crossed with matrix Gla protein (MGP) mutant mice. Mice deficient in MGP alone (MGP(-/-) OPN(+/+)) showed calcification of their arteries as early as 2 weeks (wk) after birth (0.33 +/- 0.01 mmol/g dry weight), and the expression of OPN in the calcifie...

Does warfarin therapy have a role in coronary calcification?

Some reports have revealed that warfarin inhibits the matrix carboxyglutamic acid protein (MGP), which inhibits calcification. Treatment of rats with warfarin at doses that inhibit the carboxylation of MGP causes rapid calcification of elastic lamellae of arteries and of aortic heart valves and increased expression of MGP-mRNA in the calcifying artery. Therefore warfarin use might result in inc...
