Enzyme is key to clogged arteries

29.09.2009
Scientists at Queen Mary, University of London have made an important discovery in understanding what causes arteries to clog up.

They have discovered that an enzyme called matrix metalloproteinase-8 plays a crucial role in raising blood pressure and causing abnormal build-up of cells in the arteries – both of which increase the risk of heart disease.

Heart disease is the number one cause of death in the UK. The scientists say that their research could lead to new drugs for treating high blood pressure and preventing heart disease.

Shu Ye, Professor of Molecular Medicine and Genetics at Queen Mary, University of London led the study. He explained: "Our research tells us that this enzyme plays a crucial role in the build-up of fatty deposits in the arteries which causes heart disease.

"Many patients with high blood pressure or heart failure are currently treated with ACE inhibitor drugs. However, some patients do not respond sufficiently to ACE inhibitors alone. We hope that what we've found here could be the basis for new drugs that can enhance the effects of ACE inhibitors, which would reduce deaths from heart disease."

The researchers studied mice which were genetically altered so they could not produce the MMP8 enzyme. The mice were fed on a Western-style diet high in fat and cholesterol and compared to normal mice fed on the same diet. The mice which lacked the enzyme had clearer arteries and lower blood pressure.

The researchers also studied 2,000 patients who were being tested for clogs in arteries leading to their hearts with a test called a coronary angiogram. They found that around 25 per cent of these patients had a slightly different version of the gene for MMP8 and their arteries were more clogged than other patients.

The research was funded by the British Heart Foundation. These findings have just been published in the journal Circulation Research (doi:10.1161/CIRCRESAHA.109.200279).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
