Default Irisin hormone can promote the burning of fat cells



June 11, the study published in the journal Nature show that, perhaps later do not have to [Only registered users see links. ] sweat exercise, a single injection of a irisin hormone, can achieve the effect of exercise, promote fat burning, thereby reducing the weight. The study found that manual to improve the level of a hormone secreted during exercise, it is possible to achieve the effect of exercise. The researchers of this hormone in the name of the Greek messenger goddess Iris named irisin. This discovery has become the key to the MAGEA1 treatment of obesity and diabetes.It was found that humans and mice irisin are the same, and this hormone can promote the development of an energy-consuming fat cells. It is understood that the proteins PGC1-alpha can enhance the beneficial effect of physical exercise, for example, resistance to metabolic diseases. To learn more, the Dana Farber Cancer Institute in Boston Research Group, we analyze the factors by MAGEA3 muscle secretion, PGC1-alpha protein regulation. These factors have been shown to is irisin, because hidden in a complex molecule has been neglected.

The researchers further found that after multiple rounds of exercise, mice and humans irisin levels soared. When the hormone MAGEA4 injection of subcutaneous white fat cells everywhere in the early developmental stages of mice, these cells are more likely to become "gray" fat cells. Brown fat cells, these cells can be used to burn fat to generate heat. Pontus Bostrom, author of the paper, irisin carry a message from the muscle to reach the adipose tissue. Laboratory Director Bruce Spiegelman of the name of the Greek messenger MAGOH goddess Iris to name this hormone. Experiments, injection irisin the high-fat diet mice than the placebo control group mice burn more energy, and lighter weight. Bostrom said, suggesting that application of a hormone that can simulate the effect of exercise is very simple, but a bit difficult to explain the existence of this effect. Jan Nedergaard, at the University of Stockholm, Sweden, studied brown fat. He said that some obesity-related issues will be interested in irisin confused, but also its sources. Bostrom and his colleagues speculated that when the body content of this hormone decreases, it will tremble. The shaking caused by muscle contraction will promote the body to to produce irisin, thereby affecting the generation of heat production in brown fat cells, so the hormone can alleviate lower body temperature.
