The analysis crew administered AP39 to some worms from delivery, and to others after reaching maturity. They discovered that this compound improved the integrity of mitochondria — the ‘energy home’ of cells, which produces our cells’ power, and saved the worms’ muscular tissues energetic and shifting, even properly into outdated age, and when given mid-way via their life-course. The analysis concludes that focusing on H2S particularly to the energy-generating equipment of cells (mitochondria) might someday be used as a wholesome growing older therapeutic.
