Description

Chrysovalantou Xirouchaki and a large team link a muscle enzyme to ageing in this 2026 study. Exercise switches on a protective stress-response system in muscle, steered by a master protein, and that protection fades with age.

The enzyme NOX4, which makes small amounts of reactive oxygen in working muscle, turned out to feed that protective switch. Its levels fell in aged mice and humans. Mice lacking it in muscle aged badly, with wasting, frailty, weight gain, and liver disease. Restoring the enzyme, or switching the downstream system on with a broccoli-derived compound, brought the exercise-like protection back. The findings frame one way exercise keeps ageing at bay.
