G6PD Overexpression Protects Mice Against Associated Oxidative Stress and Delays the Occurrence of Frailty
To assess the impact of lifelong overexpression of G6PD on reactive oxygen species (ROS)-derived damage and the prevention of frailty, we measured the levels of macromolecular oxidative damage in young and old mice and the we tested the neuromuscular fitness and the grip strength in old mice. Old G6PD-Tg male and female mice showed diminished accumulation of DNA oxidation (measured as 8-hydroxyguanosine or 8-OHdG) in liver and brain. Old females also showed reduced lipid oxidation (measured as malondialdehyde or MDA) in the liver. Old G6PD-Tg males, but not females, presented a small but significant increase in brain protein carbonylation. In accordance with these findings, liver from 2-yea…
