Supplementation of PQQ may reversed the alterations observed in the hippocampus of D-gal-induced mice, including elevated levels of MDA, ROS, as well as reduced T-AOC activity (Zhou et al., 2018)

The metabolites with significant changes mainly involved D-glutamine and D-glutamate metabolism, histidine metabolism, arginine metabolism, beta-alanine metabolism and alanine, aspartate and glutamate metabolism

Superoxide reporters of the DHE family yield non-specific raw fluorescence, thus quantification must rely on chromatographic separation of DHE2-hydroxyethidium (2-OH-E) by HPLC to measure O 2 and discriminate it from ethidium or other adducts, ideally alongside SOD controls and pathway-selective perturbations (e.g., NOX2 inhibitors, mitochondrial site inhibitors) for source assignment
