The genome – wide comparison of evolutionary biologist at the University of California, Berkeley is conducted discovered more than 30 genes with DNA mutations that have become more frequent in Tibetans than Han Chinese, nearly half of which, as the body in connection consumes oxygen. A mutation in particular spread of less than 10 % of the Han Chinese to nearly 90 % of all Tibetans. – ‘This is the fastest genetic change ever observed in humans,’said Rasmus Nielsen, UC Berkeley professor of integrative biology, who led the statistical analysis. ‘For such a very strong change, a lot of people would have simply due to the fact to die to die the wrong version of a gene. ‘.
We are looking for evidence of past selection, looking to find something functional in our genome, these so-calledBGI researchers obtained DNA from 50 Tibetans in the Tibet Autonomous Region of China and 40 Han Chinese from Beijing, the Tibetans were living in two villages at altitudes of 4,300 meters and 4,600 meters . Away all reported at least three generations of ancestors lived in the same place after obtaining the consent, the Chinese researchers blood samples from the participants and measured oxygen saturation of red blood cells concentration and hemoglobin content in the blood. Conducted research at the IRCM was Institutes of Health Research Institutes of Health Research and the Natural Sciences and Engineering Research Council of Canada .An understanding the controller of the heme plane is likely in order be relevant to various diseases. For example, is a state where Bariatric fat built quite due to a low energy consumption to energy absorption. Proteins as Rev-erb? to for maintaining a well cell of metabolism and energy balance points, event and in those metabolic diseases such obesity and diabetes and suggest ways to intervene where necessary.
Researchers at University of Pennsylvania School of Medicine have of a molecular circuit to help with haem to maintain proper metabolism in your body, discover provide new insights into metabolic disturbances such obesity and diabetes.
