Many of the studied metabolites are biomarkers for cardiovascular disease or related disorders, thus the loci uncovered may provide valuable insight into the biological processes leading to common diseases.
Laboratory tests used in the clinic typically monitor one or few circulating metabolites. The researchers at the Institute for Molecular Medicine Finland (FIMM) used a high throughput method called nuclear magnetic resonance (NMR) that can measure more than hundred different metabolites in one assay. This provides a much more in-depth picture of circulating metabolic compounds.
"Using this extensive analysis in thousands of people, we could identify a large number of genetic loci regulating the level of compounds circulating in the blood stream", says Dr. Samuli Ripatti, the leader of the study.
Among the findings were two new loci affecting serum cholesterol subclass measures, well-established risk markers for cardiovascular disease, and five new loci affecting levels of amino acids recently discovered to be potential biomarkers for type 2 diabetes. The discovered variants have significant effects on the metabolite levels, the effect sizes being in general considerably larger than the known common variants for complex disease have.
Also, using Finnish twin pair samples, the researchers indicated that the metabolite levels show a high degree of heritability. "This result suggests that the studied metabolites are describing better the underlying biology than the routinely used laboratory tests. Therefore, the study provides further support for the use of detailed data on multitude of metabolites in genetic studies to provide novel biological insights and to help in elucidating the processes leading to common diseases", Dr. Ripatti says.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
