Female-specific mechanism for energy expenditure discovered in brown adipose tissue

Higher activity of PGC-1α enables brown fat cells in females to achieve thermogenic activity and energy expenditure compared to males, reveals a study conducted in Japan. This research demonstrates that PGC-1α protein promotes phospholipid synthesis, which strengthens mitochondria of brown fat cells and enhances their heat-generating capacity in female mice. The findings reveal a female-specific mechanism of energy metabolism, boosted by PGC-1α and estrogen, which could inspire new therapies for the prevention of obesity and diabetes.
