"We tested for an association between genetic variants across the human genome and fasting glucose and insulin," says Richard M. Watanabe, Ph.D., associate professor of preventive medicine and physiology & biophysics at the Keck School of Medicine of USC and lead author of the paper.
"We found a novel association between fasting glucose and the melatonin receptor 1B (MTNR1B). It's novel because this is the first time a genetic variant has been associated with both glucose and increased risk of diabetes."
The study examined genetic information from 6,543 people participating in three independent genome-wide association studies for fasting glucose and insulin. The studies included Finland-United States Investigation of Non-insulin-dependent Diabetes Mellitus (FUSION) study and the SardiNIA study of aging and the Diabetes Genetics Initiative.
"The MTNR1B finding is interesting because melatonin is involved with regulating circadian rhythms, like sleep cycles, and people with sleep disorders, like sleep apnea, tend to develop obesity and insulin resistance, which are risk factors for type 2 diabetes," continues Watanabe. "More studies will be needed to understand how MTNR1B is involved in regulating glucose and associated risk for diabetes."

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
