American scientists have found under which conditions are important for the body beige fat is converted into less useful white. In the future this eliminates restrictions in food intake and not gain excess body weight. A study published in the journal Cell Metabolism, briefly about it reports the edition EurekAlert!
For the conversion of beige fat in white, as shown by scientists, meet the mitochondria — cell organelles that perform the energy functions, in particular processing of glucose. By the conversion of beige fat in white, components are subjected to autophagy — intracellular destruction.
To regulate the conversion of fat into each other is possible, as shown by scientists, using the control of gene expression, responsible for the destruction of mitochondria. Mouse, who had suspended the destruction of organelles, turning the beige fabric in white, showed a high rate of metabolism and do not suffer from obesity.
In a healthy person observed three types of fat: white, beige and brown. The first saves energy, and its excess leads to obesity and diabetes. The third keeps the body warm and is associated with thinness. Babies are born with this fabric.
The second fat, which some researchers considered a variety of the third, can turn into white, which is undesirable for health. Cold therapy and its medical simulation, allows for a short time to carry out the inverse transformation.
