New multiple action intestinal hormone corrects diabetes

31.10.2013
Scientists from the Helmholtz Zentrum München (HMGU) and the Technische Universität München (TUM), together with scientists in the USA, have developed a new therapeutic approach for treatment of type 2 diabetes.

A novel single molecule hormone, which acts equally on the receptors of the insulin-stimulating hormones GLP-1 and GIP, was observed to reduce weight and improve blood sugar. The results have now been published in the medical journal 'Science Translational Medicine', and include data from successful clinical studies in partnership with the pharmaceutical company Roche.

GLP-1 (glucagon-like peptide 1) and GIP (gastric inhibitory peptide) are hormones that are formed by the digestive tract and that control food intake and numerous metabolic processes. When glucose (sugar) is ingested, these hormones primarily lead to increased insulin release and subsequent reduction in blood sugar, but they also affect appetite regulation and fat burning.

Some of the actions, which are combined in one molecule for the first time, are already in use for the treatment of type 2 diabetes. GLP-1 analogues, as well as DPP4 (dipeptidyl peptidase 4) inhibitors, which are thought to enhance GLP-1 action, are used to reduce blood sugar. A HMGU and TUM team led by Dr. Brian Finan and Prof. Dr. Matthias Tschöp at the Helmholtz Diabetes Center, working with Richard DiMarchi from Indiana University and colleagues from the University of Cincinnati, have now succeeded in developing a molecular structure that combines the effects of the two hormones. These novel molecules simultaneously stimulate two receptors (GLP-1 and GIP) and consequently maximize metabolic effects compared to each of the individual molecules, or currently available medicines that are based on individual intestinal hormones.

The newly discovered GLP-1/GIP co-agonists lead to improved blood sugar levels and to a significant weight loss and lower blood fat. Importantly, the researchers observed that the new substance also improved metabolism in humans, in addition to beneficial effects they discovered in several animal models. At the same time, there are indications that possible adverse effects, the most frequent of which are gastrointestinal complaints, are less common and less pronounced with this approach than with the individual hormones.

“Our results give us additional confidence that our combinatorial approach of modulating brain regulatory centers via natural gut hormone signals has superior potential for a transformative diabetes treatment”, explains Prof. Tschöp. He adds a note of caution however: “Still, this approach has to go through several more years of intense research, clinical testing, and safety evaluations, before these substances may become available for patients”. Dr. Finan, the first author of the study, points out that there may be unprecedented potential: “We are quite excited about this new multi-functional agent approach and believe it could become an integral part of a next generation of personalized therapies for type 2 diabetes, as the ratio of the GLP-1 and GIP signal strengths could be adjusted depending on the individual needs of patients.” The studies which were just published in Science Translational Medicine are perfectly aligned with the research objective of at the Helmholtz Zentrum München, partner of the German Center for Diabetes Research (DZD), which is to establish new approaches to the diagnosis, therapy and prevention of civilization's major widespread diseases and to further develop these approaches as quickly as possible in the context of translational research in order to provide specific benefits for society.

As German Research Center for Environmental Health, Helmholtz Zentrum München pursues the goal of developing personalized medical approaches for the prevention and therapy of major common diseases such as diabetes mellitus and lung diseases. To achieve this, it investigates the interaction of genetics, environmental factors and lifestyle. The Helmholtz Zentrum München has about 2,100 staff members and is headquartered in Neuherberg in the north of Munich. Helmholtz Zentrum München is a member of the Helmholtz Association, a community of 18 scientific-technical and medical-biological research centers with a total of about 34,000 staff members.

The German Center for Diabetes Research (DZD) brings together experts in the field of diabetes research and interlinks basic research, epidemiology and clinical applications. Members are the German Diabetes Center in Düsseldorf, the German Institute of Human Nutrition (DIfE) in Potsdam-Rehbrücke, Helmholtz Zentrum München – German Research Center for Environmental Health, the Paul Langerhans Institutes of the University Hospital Carl Gustav Carus in Dresden and the University of Tübingen, as well as the Gottfried Wilhelm Leibniz Association and the Helmholtz Association of German Research Centres. The objective of the DZD is to find answers to open questions in diabetes research by means of a novel, integrative research approach and to make a significant contribution to improving the prevention, diagnosis and treatment of diabetes mellitus.

The Institute of Diabetes and Obesity (IDO) studies the diseases of the metabolic syndrome by means of systems biological and translational approaches on the basis of cellular systems, genetically modified mouse models and clinical intervention studies. It seeks to discover new signaling pathways in order to develop innovative therapeutic approaches for the personalized prevention and treatment of obesity, diabetes and their concomitant diseases. IDO is part of the Helmholtz Diabetes Center (HDC).

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
