... mice. Importantly, treatment of the cells with an antioxidant increased the lifespan of the red blood cells lacking Foxo3. A lack of Foxo3, and therefore high levels of oxidants, also decreased the rate of red blood cell development and led the authors to posit that it might be possible to exploit these functio...Research shows NPD1 protects a key component of vision
