This research, led by Professor Victor Zammit, Head of Metabolic and Vascular Health at Warwick Medical School, found that the enzyme known as ‘Carnitine palmitoyltransferase 1A’ (CPT1) has a switch which is thrown depending on the composition and curvature of its cellular membrane. This is the first time such a mechanism has been described and may possibly be unique, reflecting the importance of this protein to cellular function.
CPT1 is the key protein that regulates fatty acid oxidation in the liver and is critical for metabolism. Its activity determines whether individuals suffer from fatty liver in one extreme or ketosis in the other.
Professor Zammit explained: “Knowing that the CPT1 enzyme can switch and what controls it will ultimately lead to a better understanding of why some people appear to have a speedy metabolism and others struggle to curb their appetite.
“We are making great inroads to understanding the science behind our metabolism and how at cellular level it changes according to the influence of different factors – be they nutritional or hormonal.”
The importance of this work on clinical practice is that, having discovered the molecular mechanism, it should now be possible to design drugs that flick the switch of CPT1 in one way or the other, depending on the requirements of individual patients and the tissue that needs to be affected. For example, drugs can be developed for patients suffering from diabetic keto acidosis, a condition when insufficient insulin caused the body to start breaking down fat, so that the enzyme is inhibited to oxidize fewer fatty acids.
“This would be a major breakthrough in tackling the obesity crisis we now face,” added Professor Zammit.
The research, conducted in association with the University of Southern California, Los Angeles, USA has been published in Journal of Biological Chemistry as ‘Paper of the Week’ and the editors considered it to be within the top one percent in terms of significance both to fundamental science and potential clinical importance.

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
