Beige fat created from white fat by cold activation

Discovery could help fight obesity, metabolic disorders. Researchers have uncovered a new molecular pathway for stimulating the body to burn fat – a discovery that could help fight obesity, diabetes and cardiovascular disease. A McGill University team focused on a protein, folliculin and its role in regulating the activity of fat cells. By knocking out the gene that produces folliculin in fat cells in mice, the researchers triggered a series of biomolecular signals that switched the cells from storing fat to burning it.

This process is known as the ‘browning’ of fat cells. Brown fat gets its colour from iron-rich mitochondria, an abundance of which is a sign that a cell is in metabolic overdrive...
