Breakthrough in regulating fat metabolism - Body’s fat switch discovered

09.12.2011
Scientists at Warwick Medical School have made an important discovery about the mechanism controlling the body’s ‘fat switch’, shedding new light on our understanding of how proteins regulate appetite control and insulin secretion.

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.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
