Hard Hearts: New Discovery Of Bone In Heart Tissue May Explain Valve Disease
...o whichcalcium sticks in the formation of bone--in calcified
valves. "Finding thisprotein and actual bone is evidence that valve calcification is an activeprocess of laying down organized bone tissue, not a passive one, as was oncethought," says Mohler. But that still leaves the question: How did bone...

UH lab identifies first gene mutations in blood vessel disease
...een cells, of the skin, retina and arteries become calcified
and lose their resilience. Onset of the disease is usually signaled first by a rash of yellow papules on the skin, especially around the neck, groin and thighs. In more advanced forms, the skin sags and wrinkles, giving the appearance of premature ag...
Blood vessels found to signal chain of destruction in bone diseases
...Interestingly, mice lacking the OPG gene also have calcified
arteries, leading to diseased blood vessels. "We've shown that the endothelial cells of blood vessels make their own OPG and may represent a major source for the levels of this factor found circulating in serum," she said. "In the case we've stu...
