Arterial Elastin Abundance, Rather Than Orthologue Origin, Modulates Medial Arterial Calcification in Matrix Gla Protein-Deficient Mice

Key takeaways

Calcium can build up in the walls of arteries and stiffen them, which is common in kidney disease and diabetes. Working in mice that lack a protein which normally blocks that buildup, researchers found the amount of elastin, the stretchy protein in artery walls, sets how much calcium is deposited. Which species the elastin gene came from did not matter, only how much elastin was there. This was in mice, not people, and it is a preprint that has not been peer reviewed.
