Researchers at Weizmann Institute of Science found a protein called MTCH2 that helps cells burn fat and boost endurance. They studied human cells and mice to understand its role in energy production.

Modern weight loss medications can help people lose weight, but they often reduce muscle mass too. Scientists wanted to find a way to address this challenge while also helping the body burn fat more efficiently. Researchers at Weizmann Institute of Science discovered a protein called MTCH2 that plays a major role in how cells manage energy and store fat.

The team led by Prof. Atan Gross studied mice with low levels of MTCH2 in their muscles. These animals became more physically fit, developed greater endurance, and were resistant to obesity. They also had more muscle fibers, which consume oxygen and are associated with improved stamina and athletic performance.

To understand how MTCH2 works, the researchers turned their attention to mitochondria, tiny structures inside cells that generate energy. Mitochondria can fuse together into large networks or remain separate units. When energy production becomes less efficient, cells compensate by consuming more fuel, including fats, carbohydrates, and proteins. The team found that MTCH2 helps control this process by regulating mitochondrial fusion.

The researchers then studied human cells to see if the same mechanism operates in humans. They used genetic engineering techniques to eliminate MTCH2 from human cells. Without MTCH2, the normal mitochondrial network broke apart into separate units, leaving cells in a constant state of energy shortage. However, this inefficiency can actually help the body burn more fat and reduce new fat cell formation.

Why It Matters

This discovery could lead to new treatments for obesity and improve physical endurance. It also highlights the importance of understanding how our bodies manage energy and store fat.
