9.5 Modulators of mitophagy 9.5.1 Urolithin A Urolithin A (UA) is a natural metabolite produced by the gut microbiota through the conversion of ellagitannins and ellagic acid, polyphenolic compounds abundant in pomegranates, berries, and nuts (220)

GPx activity, aside from availability of GSH, is affected by other factors such as glutathione reductase activity, the amount of produced NADPH + +H + in the pentose pathway and availability of selenium

Due to the activation of the original oncogene in GBM cells, they produce ROS ( Molecular mechanisms of ferroptosis Ferroptosis is a newly discovered programmed cell death process that is morphologically manifested by outer mitochondrial membrane rupture, increased inner mitochondrial membrane density, mitochondrial cristae reduction or disappearance, normal nuclei and no chromosome condensation (Figure 1) ( FIGURE 1 Glutathione peroxidase 4 inactivation or depletion induces ferroptosis Glutathione peroxidase 4 (GPX4) scavenges lipid peroxides to generate lipid alcohols, which inhibits Fe 2+ induced reactive oxygen species (ROS) production ( Inhibition of system Xc -GSH-GPX4 activity induces ferroptosis Cysteine/glutamate reverse transporter (system Xc ) is located on the cell membrane and mainly loaded by SLC3A2 and SLC7A11 ( transports amino acids in a ratio of 1:1 by pumping in extracellular cystine while pumping out intracellular glutamate
