Variations in One Gene May be Associated with Endurance Running

17.02.2010
A few minor variations in one gene may make a difference in athletic endurance, according to a new study from Physiological Genomics.

The study found that elite endurance athletes were more likely to have variations of the NRF2 gene than elite sprinters. Non-elite endurance athletes were also more likely to have the genetic variations compared to sprinters, although the difference was not as pronounced.

The study shows an association between the gene variation and endurance, but does not establish a cause-effect relationship. Future studies are needed to unravel exactly what role the gene plays in athletic performance. The study is part of a larger body of research that is exploring the human genome and which aims to understand the genetic underpinnings of athletic performance.

Although the human genome is relatively uniform, there are variations among individuals. The researchers investigated the NRF2 gene because previous studies have shown that it may play a role in endurance performance because it:

· helps produce new mitochondria, a key cellular structure that produces energy
· reduces the harmful effects of oxidation and inflammation, which increase during exercise

“These findings suggest that harboring this specific genotype might increase the probability of being an endurance athlete,” said one of the authors, Nir Eynon of Wingate Institute in Israel. The study, “Interaction between SNPs in the NRF2 gene and elite endurance performance,” was carried out by Dr. Eynon, Alberto Jorge Alves, Moran Sagiv, Chen Yamin, Prof. Michael Sagiv and Dr. Yoav Meckel. All are at the Wingate Institute except for Alberto Alves, who is with the University of Porto in Portugal. The American Physiological Society (www.the-APS.org) published the study.

The Study
The study examined 155 track and field athletes who had competed in national or international track and field competitions. The athletes were further subdivided into endurance group (10,000 meter and marathon runners) and a sprint group (100- and 200-meter and long jump). The control group consisted of 240 non-athletic healthy individuals.

These groups were further divided into elite-level (those who had represented Israel in the world track and field championships or in the Olympics) and national-level (those who had competed in national competitions, but not international).

The study found that two variations in the NRF2 gene (specifically, the NRF2 A allele and the NRF2 C/T genotype) occurred more often in endurance athletes than in sprinters. “Eighty percent of the elite-level endurance athletes were carrying the A allele of the NRF2 A/C single nucleotide protein, compared to only 46% of the elite-level sprinters,” Nir. Eynon said. The study also found that the combined NRF2 AA+ NRF2 C/T genotype was more frequent in endurance athletes than in the sprinters group and the control group.

“So,” concludes Eynon, “some of us are truly born to run.”

Physiology is the study of how molecules, cells, tissues and organs function to create health or disease. The American Physiological Society (APS) has been an integral part of this scientific discovery process since it was established in 1887.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
