Scientists at Schepens Eye Research Institute have found that reducing the levels of vascular endothelial growth factor (VEGF), which is best known as a stimulator of new blood vessel growth, in adult mice causes the death of photoreceptors and Muller glia - cells of the retina that are essential to visual function.

Researchers have found the first direct proof that a key protein drives the clogging of arteries in two ways, and that lowering levels of it opens them up, according to study results published in the June edition of the journal Circulation.

A hypertension medication called olmesartan medoxomil is effective in reversing the narrowing of the arteries that occurs in patients with high blood pressure, according to a new study.

Researchers at the University of Massachusetts Medical School (UMMS) report today on a new technique that improves the ability of scientists to target individual genes for inactivation—a technique with broad potential implications for both basic science research and human disease.

Overweight but active men responded dramatically better compared to their inactive counterparts in a first-of-its kind study from Indiana University that examined the vascular response to exercise in overweight men.

Low-density lipoprotein (LDL), a transporter of cholesterol, may also contribute to vascular diseases by a previously unidentified mechanism, according to a report published online this week in EMBO reports.

Diabetes is associated with the development of vascular (blood vessel) disease. As we age, vascular disease becomes more common. It has been thought that females may be more susceptible to the earlier development of vascular disease, as vascular changes are observed in females long before any significant development occurs in males.
