Washington: In a new study, scientists have isolated a natural hormone from muscle cells that triggers some of the key health benefits of exercise.According to a team led by researchers at Dana-Farber Cancer Institute, the protein, which serves as a chemical messenger, is a highly promising candidate for development as a novel treatment for diabetes, obesity and perhaps other disorders, including cancer.“It’s exciting to find a natural substance connected to exercise that has such clear therapeutic potential,” Newswise quoted Bruce Spiegelman, senior author of the study as saying.Spiegelman dubbed the hormone ‘irisin’, after Iris, a Greek messenger goddess. He said the discovery is an important first step in understanding the biological mechanisms that translate physical exercise into beneficial changes throughout the body, both in healthy people and in preventing or treating disease.“There has been a feeling in the field that exercise ‘talks to’ various tissues in the body,” Spiegelman said.According to the report, the irisin hormone has direct and “powerful effects” on adipose, or fatty, tissue -- subcutaneous deposits of white fat that store excess calories and which contribute to obesity.When irisin levels rise through exercise, or, in this study, when irisin was injected into mice, the hormone switched on genes that convert white fat into “good” brown fat. This is beneficial because brown fat burns off more excess calories than does exercise alone.Along with stimulating brown fat development, irisin was shown to improve glucose tolerance, a key measure of metabolic health, in mice fed a high-fat diet.Spiegelman caution that the discovery won’t allow people to be able to skip the gym and build muscles by taking irisin supplements because the hormone doesn’t appear to make muscles stronger.
