Increasing certain proteins in the blood vessels of mice, relaxed the vessels, which in turn lowered the animal's blood pressure, researchers have found.

"The paper demonstrates that cytochrome P450 plays an important role in the management of high blood pressure, a disease of enormous public health concern," said Dr. Darryl Zeldin, acting clinical director of the National Institute of Environmental Health Sciences (NIEHS) and senior author on the paper.
The study was conducted by researchers at NIEHS who teamed with investigators at the University of North Carolina at Chapel Hill (UNC), Medical College of Wisconsin, Milwaukee, and Oregon Health and Science University, Portland.
The researchers created animal models that had a human cytochrome P450 (CYP450 or P450) in the cells that line their blood vessels.
The mice with the P450 generated more substances called epoxyeicosatrienoic acids or EETs, known for their role in protecting the cardiovascular system.
EETs relax and dilate the blood vessels and fight inflammation.

"This is a great example of a basic finding that improves our understanding of a metabolic pathway that can be used to develop improved treatments for those suffering from a common disease like hypertension," said Dr. Linda Birnbaum, director of the NIEHS and the National Toxicology Program.
